As NEW as Used can BE

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? :)

you gettin fresh with me? lol



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

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.

Autocrossed in Tavares on Sunday with a Porsche Club.

The car is just so damned beautiful.

Plans for wheels?

949 has 6ULs in a size that might fit... :)

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.

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.

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.
