Todays task consist of unlooping and un capping the lines that route to the Duty Valve.

The other day in doing so, I had broken the nipple off the old solenoid and I ordered a new one from Mazda. What a difference visually. The Duty Valve is the Pre/WG solenoid that controls the pressurization for both waste gates and acts like a boost controller.

Is the Power FC still the "state-of-the-art" for FD tuning?

I remember everyone tuned FD running them 10+ years ago...

Its the most consistent, easy, and user friendly.

Adaptronic seems to be more precise for bigger horsepower like megasquirt.

You can use the Power FC for up too around 400hp. Thats of course with upgraded intercooler, injectors, fuel pump etc. Anything above that, users tend to upgrade their ECU.

Drove around Lake Wales Yesterday because we had an appointment at Bok Tower Gardens where we are considering to host our Ceremony and Reception.

Chasing down this boost leak is killing me. I'm taking the car to Pettit Racing tomorrow morning to do a boost leak test and remedy.

I just replaced the pill restrictive hoses that connect to both wastegates. Luckily in doing so, one hose that was suppose to have a pill didn't and needed to be replaced anyways. The pills act like a boost controller. Yes I could have bought two controllers but then that's more hose and two more objects in my bay. When I upgrade to the 99 twins, then I'll install boost controllers.

So why a front plate on the FD? :)

--Ian

you gettin fresh with me? lol

This is what caused my so-called leak...
Actuator arm had fallen off

https://www.miataturbo.net/attachmen...ine=1456526177 Untitled by Gerald Mugar, on Flickr

So now i can boost .73bar all day like I want to but it doesn't just come that easy.

The secondary is boosting .4? bar now and I need to find out why.

The car is just so damned beautiful.

Plans for wheels?

I plan on getting 18inch street wheels that are bronze in color. Its still an indecisive decision which 5 or 6 spoke wheel we are going to choose from but its gonna be 18x9 or 18x9.5

Autocross video from 02/28/2016 held by the PCA

Installed Jeffs PFC ECU Bracket so its not flopping around. Especially while Autocrossing. Interested to see what other intuitive products he has in store for the Rx7

So I developed an exhaust leak with the stock twins. It's inevitable. Especially since just about everything has been touched and replaced but the twins with 147k miles. Yes, that number is correct. I put on 22k miles in about a year 20 months on a rotary.

So, tomorrow I am checking out a set of N3G1 99 spec twins along with a HKS down pipe, and a bonez or rx7store.net midpipe. Still need to figure out what it is that's replacing my stock midpipe.

I'm hoping to get it done before autocross this weekend. We'll see.

What they look like and picked them up in Orlando. They were from the owner in Sarasota who had to commute for some work and it worked out in less then a day to be picked up.

https://www.miataturbo.net/attachmen...ine=1459302337 Untitled by Gerald Mugar, on Flickr

I picked up an HKS Downpipe and the twins which seem to be either rebuilt nicely with decently clean and new hardware or its really just that they are extremely low miles.

Either way I'm happy for the secondary turbo fix I'm currently going under way. The 93 turbos are on their way out with just a coolant line and two oil lines in the way of removing the setup.

Heres what the Y-pipe looks like inside. We suspect the Secondary is blowing oil.

https://www.miataturbo.net/attachmen...ine=1459302337 Untitled by Gerald Mugar, on Flickr

You worried about that crack in the housing? It looks kinda nasty...

No. It's very common and won't be an issue. This crack isn't bad at all. There are exhaust ports with two or multiple cracks that owners install. This set is extremely clean as be been told sharing pictures with friends.

Some people think the 99 twins are overrated and going single is the best decision if the turbo setup is already removed. But these are my thoughts:

I'm already invested in a properly working twin setup. I.E. New vacuum hoses, new solenoids, new parts all oem.
The 99 twins spool faster then the USDM and are more efficient along with adding 40+ additional hp tuned over a tuned USDM
Model.

There are BNR twin turbos which they port the housing for the wider fins. They are even better and more powerful. I would have liked to bought the BNRs but I would be spending 3k when I got a killer deal on the 99 spec turbos.

The turbos and a very expensive HKS downpipe was picked up for 800.

I'd keep the twins too...some FDs need to be left at least sort of as the factory intended.

Yeah I think it really just comes down to the condition of the car:
if it's minty fresh with all maint done and a ton of cash invested to keep it as clean and original as possible (as yours seems to be) keeping the twins is likely a good choice

if it was #racecar or the rats nest of vacuum lines was disintegrating or the car was a nightmare, switching to single is almost mandatory.

Single is almost necessary in case of a standalone ECU. The PFC is mostly a tuneable stock ECU, if anything.

Your point exactly. And I am not exactly stock from the dealer lot but I want to make it OEM+ and really enjoy the car. I'm not doing it for the compliments but a lot of Rotaries fellas seem to enjoy the well kept clean stock look.

He really loved his car and paid whatever it costed him to drive it. The Brand new OEM built from scratch motor he had Lowes Automotive build for him costed 10k. That shows you his dedication. And Also that there weren't any REMANs available.

It is the easiest way to tune the car with the hand held. It is a bit outdated but its simple and to the point. It doesn't need any more then that.

Why is that? Too hard to control the various flappers with aftermarket?

--Ian
(in the market for a clean, stock, low-mile FD).

Because it required dedicated logic for that particular application, and given that most companies don't even have a PnP model for the FD, they won't bother to implement it. Poor ROI and all that.

Can't you control all that with an Adaptronic or Haltec? I have an old Navy buddy down in the Savanna area that works at Gulf Stream with a BNR setup he is prepping for E85. We talked a lot about ECUs with his car since we were both going though ECU choices around the same time. I vaguely remember him saying something about the two aforementioned ECUs being the only ones capable of controlling the engine with the twins. I wanted him to try MS3 but there is so little support for it for FDs.

The PFC is the most popular choice for the community for the twins. You can use it for a single setup but it's not as precise as adaptronic. With adaptronic, your power is limitless.

And for MS3, there isn't many users that I've seen. I'm not sure if it's because of what you mentioned or because it's unfamiliar. I'm familiar with MS3 and I would assume if you find a tuner he can adjust everything for you like a normal session.

Btw just ended tonight at 12:30. The 99 spec turbos are in and we are going to work on the oil and coolant lines tomorrow. We'll have it wrapped up ready to rip. Can't wait.

I also purchased and installed 99 spec twin turbos since I had an exhaust gasket leak on the block to the lower exhaust manifold. I was also burning oil in the secondary(so we think)

Between the exhaust ports was cracked

Open Down pipe start up

Still didn't fix the lower boost on the secondary. The 99s pull a lot harder because they are slightly larger then the 93 usdm models. And they are more efficient. Reason is still being determined why the sequential system on the secondary is running lower boost. Boost on the primary hits hard at 12lbs. Im working on the secondary to match that same psi level to redline.

I soften the dampening on the Ohlin coilovers to help out with my oversteering issue where my tail end likes to slide a lot. This helped out a lot during autocross this weekend.
I am thinking of unhooking my rear sway bar in the future for the next event.

Dude, those ES Miata's are like a second faster than you. What kind of tires are you on currently?

There is one ES Miata driver that was faster than him by 2 tenths, so either you're reading the results wrong or exaggerating. Most of the ES Miata guys here in Central FL have been autocrossing for decades. Gerald and I are still fairly green with less than 2 years under our belts, BSP #1 here. Gerald, I'm pretty sure you will need some wider/stickier rubber if you want to take that Street Prepared FTOD from me.

Eventually Ill upgrade from stock 16x8s running 245/45/16 to an 18x9.5 with 265/35/18

But For now, I'm tweaking things on the car to have a nice setup running autocross. I just lowered the dampening a bit to give the car some body roll because I was too stiff and sliding rear happy. That seemed to improve a lot. I am also going to un hook on end link to the sway bar in the rear suggested by Owen to see if that further improves my performance. All in All it was a blast and we all did pretty well out there.

8" rims are right in the middle of most manufacturer's recommended range for 245 tires. That's only "pinched" if you're into oni-kyan.

That sort of goes against everything I read on here. Didn't Flyin Miata and 949 do some pretty extensive testing on this already and a 225 on an 8 was faster than a 245. Most of the fast guys here in my region ,that are not limited by rule requirements, even go as narrow as a 205 on an 8" for autocross.

A national solo racer who drives a 3rd gen rx7 uses a 245/45/16 tire on stock wheels.

I'm not aware of any testing showing a 225 on an 8 being faster than a 245 on an 8. I'm not sure how you'd do that on a Miata anyway, AFAIK there's only one tire available in a 245 that fits a Miata. That's a Hoosier, and I'd be very careful about trying to extrapolate general trends in street tires using data from Hoosiers.

205s may be faster than 225s on lightweight, low-powered cars on big tracks, but if so that's not because the wheels are too narrow. It's because the grip doesn't make up for the extra drag from pushing a bigger tire through the air, or the rolling friction on the pavement. The break-even point on that is going to be very sensitive to power level, aero, track configuration, etc, so I would not try to apply them to an FD that weighs 20% more than a Miata and makes 50% more power.

For an extreme example, back when DOT R comps were legal in stock, Integra guys used to run 275 Hoosiers on 15x6 wheels. The 15x6 wheels were required by the rules, and the 275 Hoosiers were clearly not operating at their best, but it was still faster to put 275s on those wheels than it was to use 225s. Again, this is a Hoosier, so don't extrapolate too much from it. :)

Here are two threads that sort of go against your argument.

https://www.miataturbo.net/wheels-ti...25-tire-49858/

https://www.miataturbo.net/wheels-ti...-wheels-61867/

Some very fast people in these threads with proven results. I honestly thought it was pretty common to run a slight stretch. I run 195s on my 8 inch wheels and am consistently top 3 locally in a pretty contested class. We also had one of our local pro guys (John Brown, winner at Dixie Nationals STS Miata a few weeks ago) run back to back V720s in a 225 and 71R's in a 205 and the 71r's in a 205 were faster at our lot by half a second. Again, this is all autocross and strictly street tire stuff. His 3rd and 4th run was on the 71r's, the added cones are there because only 3 runs count in pro.

But were talking about the Rx7. Not the Miata. Those are two completely different platforms of suspension, power, and wheel base.

This all came from the "245s are pinched if you're into stance" comment. It's more of a, just because the manufacturer says something doesn't make it definitive thing, I guess. Won't keep hijacking your build thread. Atleast it's keeping it on top of the front page, lol.

90civicHB, you're missing a point here. 245's on an 8 will not be utilizing the 245 to its max potential, but it will be faster than a 205 on an 8 (though with less feel, and less progressive breakaway). A 205 on an 8 will be faster than a 205 on a 7, because the slight stretch will provide better feel and allow you to make the most of the tire.

as far as being pinched, Codrus is correct -- according to the tire manufacturers, a 245 on an 8 is just fine.

949's recommendations are very different from manufacturer recommendations because he's more interested in making the most of a given TIRE size, rather than making the most of a given WHEEL size.

Replaced the hood latch release cable because it broke on the molded plastic part that creates tension. I can now see that Mazda revised the part by adding a little bit of metal overlay.

I also had to replace the throttle cable because the older one was looking pretty shabby.

I'm going to DGRR this week. Any miatas going? Some show up to the meet.

This past weekend was awesome at Nantahala Village were Rotaries on the east coast gather for a 4 day event.
Jeanne and I drove up to Atlanta late Wednesday afternoon taking back roads from the Florida Georgia line to Macon on mostly US23. We took our time sight seeing and viewing the Old towns of America like we always do for trips and enjoyed the cruise. We rather not take a Interstate to preplanned destinations if we have the time to avoid them.

The next morning was Thursday and I noticed a big decrease in power other then my slow engagement of the second turbo and low boost. This leak and power loss was affecting the entire power band and there was a big whoosh sound when I got on it. GREAT! only boosting close to 6lbs.

Dale was quick to point a finger and say, "well that doesn't look good. Your problems right there!"

I tore a nice slit in the exhaust pipe to the intercooler. I was glad it was something we can fix with ease and that it wasn't an expensive one. Dale quickly told me that Addicted Performance might have a stock pipe laying around from their work on rx7s. So I crossed my fingers and hoped the entire trip wasn't handicapped to waste gate pressure at DGRR. But I was also happy that it wasn't anything else.

That night we got to Addicted and what do you know, Dale was right. They had a spare hose that they were ready to toss out for that same very reason I had just experienced earlier that day. I paid 20 bucks and had the tools to do a quick but very hot install because we take the dragon to get there. 10 mins later and I'm back to 12lbs primary. Wahoo.

Drove home after dinner at Calhouns which is in Maryville with a group of 13 people. Dinner was good and we are exhausted from the barbecue and long day of driving. We unfortunately took the Dragon back to our lodge and it is no fun driving it at night. It is dark, the percentage of danger increased dramatically and I'm tired. We pushed on and in the middle of the run I get dizzy and somewhat get vertigo and pull to the side because I lost focused. The tree line ended and my headlights hit across the valley to the other side of the mountain and tripped my brain out. The Depth of Field like in photography played games with my sight so I pulled off. I let the other guys in the group drive ahead of me and I followed last regaining my focus. WE all made it back to the village safe and sound.

The next day the group did a run on the Cherohala Skyway. Before we headed out I wanted to know why the car was feeling so out of place and my confidence was out the window. The car didn't feel right to me. I come to find out the dampening on the front struts are at two extremes of full stiff and full soft. NO wonder. This isn't the car that feels great out on an autocross coarse pulling times right behind BSP class. So I dampened all four struts 8 clicks from full stiff. I also was too high on all four tires. I was maximizing my fuel economy up to Atlanta because we all know rotaries are excellent on mpg. Not.

I was at 45 all around and lowered it closer to my Autocross pressures which are 32 up front and 29 in rear. I had 36 up front and 32 in the rear after the deflate. After the adjustments, the car felt normal to me again. I regained my confidence and ran the rest of the day proud and confident. I can't believe how I'm starting to feel the car out and notice when something is wrong. Its taking a while this time around. We drove out to Bryson City to wash the cars off of the extermination performed on the runs and ate dinner at Pasqualianos.

On Friday, the event holds a classic meet for all the rotaries to participate in Judging for best generation RX7s and receive an award that evening. So I got my car at the site rather early. I won't say how early but it was brisk at low 40s. Got there and saw that everyone had left their cars in the lot over night. There were two unofficial parking spaces left so I pulled backwards into one. I walked back to my cabin made coffee and got ready for the day. I let Jeanne sit back on this event so she isn't overloaded with cars this cars that blah rotary brap brap. When I walked back to the main lot, everyone was already out cleaning their cars with detailer and rags of micro fiber clothe. So I began my quick clean up of the engine bay and wiped all the pollen that the Appalachian had given to me. I detailed the outside just in time and the meet was underway.

I took some pictures of other rotaries and enrolled in the car show. The meet closed at around 12 and Jeanne and I headed to Bryson City to enjoy each others company as well as eat lunch and go shopping at mom and pop venues.

We ate lunch at https://www.theeveretthotel.com/bistro.html which is a farm to table restaurant and it was FANTASTIC. Not expensive at all. It was delicious. After Lunch we walked around antique shops, stopped by the local brewery to try a flight of beers and bought a bomber to bring back home. We also discovered that the train depot in the middle of the city does rides through the mountains leaving at 10 and arriving at 3pm. It is something we might do next year. The though of riding a train along mountainside and through tunnels excites me. Its something a car can not do.

We walked back to our car and stopped by an old Soda Fountain business and had Chocolate and Vanilla malts for the ride back to the resort to meet up with the Florida crew to eat dinner at https://noc.com/places/restaurants/r...end-restaurant

Super delicious food and big portions. This restaurant was inspired to feed hungry hikers. Plus its on the river with locals fly fishing and kayakers. I ordered local trout tacos which was good and Jeanne ate the Sherpa. For dessert there was peach and apple cobbler. We were excited to get the blackberry cobbler but they changed it up a bit. Don't get me wrong. The apple cobbler topped with vanilla ice-cream was just as good.

So we paid our bill and head back home for the raffling prizes and awards. Jeanne and I held our tickets for the drawings and we won a long sleeve DGRR shirt, mazda iron on badge, IRPerformance Poly Urethane Motor Mounts, two adaptronic hats, Concentrated jug of rubber/vinyl cleaner, and some miscellaneous stuff. It was a good roll for us. But that didn't end the night. Awards for best car was being announced. I'm already pretty happy about the motor mounts.

So we hear the awards being named for best SA and FC with first, second, and third place. It was time for the FD awards. And what do I mistakenly hear? Third place FD goes to Heraldo!!! Now I was confused because it wasn't my name. But I've been called that in the past by friends and it couldn't be me. There were too many other good looking FD's out there with single turbo this, AERO that , Widebody, 3 piece wheels and so forth. I'm just a simple clean FD that stuck to how he wanted to share what an FD should look like for others to enjoy. And that is just that. I was a simple clean example of a car that we all love. And I received 3rd place after I was called up more then once and car was described as Montego blue.

I was super honored to receive the award and very gracious. I almost wanted to grab the megaphone and say an Academy Awards speech naming Jeanne as priority of the award.

That ended my day and my entire year of hard work getting the car to the point to where it is at right now.

As a bonus for the drive home, the car performed 342.7 miles on a tank of gas before triggering the low fuel light. I filled up 15.63 gallons which equates to 21.9257 mpg.

Remember I'm not tuned but running the base map off the PFC ecu. We also took a very nice curvy road back home that is in North Carolina. I will get that route later tonight to post it up. It was a beautiful drive with creeks alongside of the road, lakes, and falls.

Pictures follows......

Man that Rx-8 looks ugly parked next to three FDs. :)

Thank you. I'll be posting some pictures that I took at the event shortly. Surprised that I won 3rd place for best 3rd Gen

This week the car is going to kilo racing so they can tinker the low secondary boost. I am experiencing a 12-4-6 pattern.

While its there I have a few things getting down.

Brand new oem tps sensor installed

IRPerformance motor mounts

Elite rotary oil pan brace ( looks like I'm leaking oil around the brace and on the oil mixing pump lines) so when they look deeper into the leak, I have a set of steel flex lines to replace the plastic lines.

Fixing the 99 fog lights. They light up connected to the battery but not when hooked up correctly to oem connector. I'm receiving power too but it's all weird.

Banzai Racing delete kit

I'm dropping off the Hks RS intake to get painted and clear coated silver along with the Hks S pipe. to have an oem look. I cleaned and have the Hks filters but I'm going to use the K&N filters instead.

I also purchased a HKS twin power.

Untitled by Gerald Mugar, on Flickr

So I got back news from Kilo Racing with and update that is upsetting but comes with opportunities.

The car wasn't leaking oil from the oil pan as I thought it was. It's leaking from a broken oil mixing pump line. Its basically severed. He offered to do a fix to it that I did not want to do but asked him to do it the right way. He offered a different fix since I'm to be Wed this September. I'm still having him install the oil pan brace to prevent future leaks from the engine flexing.

I said to him lets do it the right way because Jeanne and I drive this car a lot and I autocross it on occasion.

He hasn't fixed the secondary Turbo issue because this is a new issue.

We discussed a few things and he mentioned that in order to replace the lines he needs to remove the motor. I was apprehended by that sentence and asked to call him back. I talked to a few people to make sure there wasn't another way to do it and to have my rotary friends reassure me that this is the way to do so and the easiest.

So I called back and asked a ball park number that'll stick to let me fiance know and be prepared for with tonights dinner and opening a really nice bottle of wine thats several hundred dollars.

I am having the injectors sent to marren. The previous owner has a reciept from 2004 when he had them rebuilt. So it'll be interesting to see the differences once again.
I ordered new injector grommets since marren will more then likely provide new o-rings.

I purchased a new oem fuel pulsation dampener and new fuel pressure regulator. I was contemplating ordering the new fuel hose that connects the primary and secondary rails.

I like to get things powdercoated to look nice but today isn't the time to do it. I simply can't strain the wedding funds anymore. We still need to pay off the remaining balance to the venue, pay for the catering next Friday, and find a florists, photographer, and music. Luckily we already have the dress. Thank god.

I do need an efini y pipe. I'm going to ask kilo if he has one. Well degrease the engine bay though it's pretty clean from the view up top. I'm pretty sure it's ugly down under and inside.

I'm skipping the harness unless kilo says or recommends a new one since they are about 840.00 from my dealership and there's only one in North America.

Kilo is going to inspect the sequential system. All the solenoids and vacuum hoses are a year old now. But it'll be easier when the motor is out.

The coils are new as of 16 months ago. He is suggesting I hook up the choke again that Pettit racing deleted. Each mechanic has there own points of views. I'll just let him do so.

We will block off the air pump with the delete kit I purchased.

and just Purchased an efini y-pipe and crossover

DSC09219 by https://www.miataturbo.net/attachmen...ine=1463232287
DSC09099 by Gerald Mugar, on Flickr

So the motor is pulled out and Kilo said one of the injectors is potentially leaking. Not from the diffuser or metal grate but possibly from the body. He sees stress cracks on a couple of them.

So He is installing a set of 99 injectors he knows works well. I asked him if we should take them to get cleaned and flowed and he emphasized that they are good and work well.

He also looked around the turbos and thinks some lines are not correct for the secondary turbo. Ill confirm with him tomorrow when I stop by to drop off the new emissions harness I just dished out.

He said that it is his recommendation to replace the harness since the car not only has 155k miles and is 25 years old but because a couple of clips are broken and the wires are brittle. FML

The car has been in the shop since May 2nd but because I had to order parts along the way and wait for them to arrive, is wait pushed my car back from getting fixed any faster.

And its funny that David Hayes was there pulling out my motor on my car. I saw his car there when I dropped mine off and it looks fantastic.

Im heading over to Kilo Racing now to drop the harness off. Ill have more pictures taken once I'm there.

Everything got done as I hoped it would. I was a bit hesitant in my first year of owning the car but regret not going sooner to Kilo.

I have absolutely zero oil leaks. Hooray!!! I hope to not replace the Oil mixing pump lines ever again. Though, I took advantage of the situation being that the motor was being pulled for multiple things.

Today I installed the Hks twin power and man does it go through the power band ultra smooth. I couldn't believe it. The motor felt effortless. (could be that new harness too)

So the boost is not where I'd like it to be. It doesn't drop to 3 psi like it used to before I took it to Kilo Racing. It drops at 8psi where it should and climbs back up to .67bar

I tried to manipulate the PFC with boost levels between the turbos and percentages but I couldn't get it to .8bar

I kept blowing off couplers every time I took the car out to day on the exhaust intake side.

We'll some pictures after 7 weeks of diagnosing, ordering, and performing on the car.

Just read the thread, very nice work I love it!

Carry on

Thank you ajay842. I'm relieved that the forum and its admins nonchalantly let the thread transition itself the way that it did. I feel it's almost like a journal.

This is what lunch looked like today with both my baes

So what do you think of the Mazdacomp bushings? My new FD needs a few bushings (all the inside ones on the driver's side rear) and I haven't figured out what to put in there yet, other than NOT poly. :)
