Nice! Sounds like she's purring.

Looking good Jeff. The car looks nice too. ;) Sounds like a nice solid idle.

This has got to be a thing. I know first hand 4 people who own a Miata and daily a Jetta... :dunno:

That is a nice idle, especially for a first start. Well done!

I've been gazing at your engine bay shot for a while. It's so clean and lovely.

It's gotta be the 40+mpg...at least for me. Gotta love the torque of a diesel. I love the Miata, but it would make me go broke in fill up costs if it was my daily. At least, with how I drive it! I get about 600 miles a tank on the Jetta. I'm lucky if I get 300 on the Miata.

It really has turned out well. I have some thoughts on making it better, but it would be either too time consuming for the benefits of appearance, or too expensive(relays instead of fuses, vacuum block, pretty Moroso overflow tank).

Mine is the VR6 (torque :cool:) and it does alright on fuel consumption but it's no 600 to the tank and I have to put premium in it.

My Miata is probably getting 180 miles to the tank.... :facepalm:

Nice, I love that VR6 sound. With these injectors and the pump I'm probably going to be facepalming soon as well.

Luckily I'm going to be towing the Miata to events soon once I get my tow hitch welded onto the Jetta. No more pain and suffering in my lats from sitting in race seats for 2 hours straight.

That drive to MRLS and back destroyed my body. I love the seats...just not for long periods of time.

You realize that the EV14's should actually get BETTER mileage than those crappy ancient rc's you had right?
It always confuses me when people associate injector size with gas mileage, like its 1998.
Big congrats on making the switch. You'll enjoy them every day, and thank yourself for doing it.

I guess that old stigma was associated with injectors in my head. Makes sense after watching a comparison video of the RCs and the IDs. Glad I did it. Just want to go for a drive but I'm still waiting on the plastic to do my cowling project.

I won't get pulled over with no front bumper...right? ;)

over a 9 second window. Pretty flat afr but the engine rpm oscillation is being annoying. It isn't much, only 20 or so rpmdot, but you can still "hear it". Getting some oscillation in timing and pwm as well. Well, not a lot, but 1 degree and roughly 1% of pwm oscillation. My PWM table is flat in that area so I'm not sure what is causing it. Maybe too sensitive on my closed loop setting for these injectors?

https://www.miataturbo.net/attachmen...ine=1411347258

Yeah it just looks like the closed loop settings are causing some overshoot. Not real familiar with the latest MS software/tuner studio but I'd guess a bit too much I and not enough P.

It would help you if you kept spark advance flat in the idle area (or maybe bump it up a little a low RPM to provide an automatic correction).

I always got best idle quality with a richer mixture than that (maybe 13.5). What mixture gives highest vacuum with your IDs?

ID's can for sure idle at 14.7

Very true. The odd thing is that I barely had to play with my idle VEAL to get close to stoich.

When I start autotuning, I believe I'm going to increase my VEAL map by about 5%. Just puttering around the neighborhood I saw it try to adjust +4 on certain cells. Don't want to enter boost lean to enrich later, just seems like a recipe for disaster....actually it not only seems but it would be.

Vlad, I think the rich fuel smell we were smelling at MRLS was due to that O-ring leak. I think it only was noticeable under high boost, and when I removed the FPR, it was the icing on the proverbial bad seal cake.

I haven't smelled fuel since I did the install so it makes me think that is the culprit. At least I hope it is. Messing with injectors and fuel pumps is not my cup of tea. When I was doing the fuel pump and was soldering in the new connectors, I think I used about 3 times as much heat shrink as I would normally. On that first key on, I was scared the car was going to blow up.

Also, here is some crappy plastic welding pictures. The bastards on youtube make this look way too easy. I think, if I make pieces that people/me can see, I'll use a rubber dough scraper from work to smooth the still hot plastic more uniformly flat. Doesn't help that this was textured, and it would be hard to recreate the texture(sponge?).

Still, for a first attempt, and not having sanded it, not bad.

If you are wondering what it is, it's the cover I made for the headlight relays to help protect them from the elements a little better. I couldn't bend the corners without cutting it so I used a little filler rod on the inside joint, and then melted the exterior plastic to smooth the joint over. It is solid, I yanked on it pretty hard and it didn't budge. Should be great for the cowling project,especially since I don't care about how perfect it looks, just strength.

Looks worse in the photo than it is in real life, camera picks up a lot of light reflection that you don't see. *He says, rationalizing*

https://www.miataturbo.net/attachmen...ine=1411389626

Yeah, not a bad strategy. You always want it to trim down.
Makes sense on the o-ring, since you obviously have no other leaks.
You might want to look into getting a AFPR in the future - cause bumping it up closer to 70 will get you better spray patterns/atomization and efficiency

You and I think alike. Seems, after much reading, they like being at least 60psi fuel pressure, 70-80 ideal.


Just one more damn thing to add to the list of inevitable purchases.:rofl::bang:

question on a fuel pressure gauge. Wouldn't it be easier(read cheaper) to wire in a sender to megasquirt rather than a physical gauge? Can't imagine there to be a lot of variance in fuel pressure with a AFPR, except in a "you idiot you are out of gas" moment.

its up to you. many fpr's that I've seen have a gauge right on them, so maybe you can get one of those just cause its so easy/simple.

This may be a stupid question, but what exactly do you do with the stock FPR when you convert to an AFPR? Down the road I'm looking to do this, and I assume you will just remove it entirely.. but then what goes on the end of my fuel rail? I guess a custom fitting or something.

yeah you just block off the spot if mounting in different from oem spot

Cool, thanks for the info.

So going back to my slight, tiny idle oscillation issue. Crazy how a tiny amount of timing change, makes things purr. I added 1/2 degree of timing advance and it is like buttah. It will only occasionally oscillate <10 rpms. It is beautiful.

I do need to stop driving it with my bumper off. I think I almost caused a couple accidents this morning due to people rubber necking. Sadly I bet people think, "that damn juvenile delinquent has been drifting his car and tore off his front bumper!" ala Turbofan style.

No worries, just sharpie "I DIDN'T DRIFT ON PURPOSE" all over the car :giggle:

:bowrofl::bowrofl::bowrofl:

best

friday

ever

even though I had to bail early it was worth the 6 hour trip and the sunburn

I love how much we pissed off...everyone, at the diner. Eclectic group of people yelling about Miata crap...hilarious.

I too was sad I had to bail early but it was totally worth it. Next time I'm towing the Miata behind the Jetta in comfort. Although, on the drive back, I think the only reason I didn't pass out and crash is due to how painfully uncomfortable the car is after 3 hours.

Well, I know what I'm building this weekend. Not sure what parts I'm going to use it on, but when I do the brake ducts, it'll certainly give me a perfect mold to the lip opening as Hornetball did by hand.

I've always wanted to make one. This guy has one of the best heating solutions I've seen for equal heating, which is usually the hardest part of this. I have a space heater that rotates 90º and blows hot hair which I will use instead of his quartz heater.

Hmmm . . . taking orders?

No plans, no. First I gotta live up to the hype I've made about this ducting. Then sweat in nervous anticipation to hear what a fellow perfectionist (Revlimiter) thinks of my work.

Then I'll let yah know if I make anything else!

(Really though, this would only be for my nerdy desire to make cool things. Ain't nothin' "in the works".)

Well, that sure puts the rest of us in our place. LOL. :fawk: ;)

Stop being such a woman and reading into things Rick.:dealwithit::giggle:

I just want to make sure he likes it before I agree to make any more....Then, maybe for a select few(labor is high). Hardest part is the variance in radiators, intercoolers, and piping. Rev's is quite similar to mine so I'm making all the shapes, and letting him cut the intercooler hose holes/mounting holes.

Us perfectionists can recognize our own. I've been known to spend full weekends redesigning logos which have the final version only fractions of a point different than the original. 3 points are roughly 1 millimeter. lol

It's all in the details.

Also, nice plastic welding!

Nice

I'm honored that my car has a place in this thread, even if it's just to be made fun of.

:laugh:

:party:

I ain't laughin' at yah, just at the awesome sharpie notes! You crashed it and owned it rather than cryin' in a corner like some would. Plus your short shifter is godly(compared to my slushbox). Did you get your fuel cut out taken care of?

He ran alloffit his Monday when his wastegate line came loose and shot 4 foot flames when hitting boost cut ��

Awesome!
https://www.miataturbo.net/attachmen...ine=1411570323

lol if only we had a pic of it. Drove a couple more laps never using more than like 1/4 throttle because otherwise it'd hit boost cut, lulz. Pop BANG.

Does your boost cut only cut spark and not fuel though? Mine was surprising as hell when it happened(tuned my ebc finally so it doesn't happen anymore) but I never got bangs or anything spark/fuel related.

Seems like that's the case, resulting in the 4-foot flames :laugh:

That's, "We" perfectionists. ;) ;)

drifted- on accident
shot flames- on accident
ALLOFIT- on accident

Do you do anything intentionally? :giggle:

Nice ninja edit :giggle:

Spinners await

Please do this for the laughs. Go buy those spinner beanies(can't remember the name), cut them off and put them on your center caps. So ludicrous to see a 2871 turbo'd MSM scoot around the track with little blue and red spinners going wild.

You could turn your car into an ironic badass. Funky on the outside and amazing internals. Just imagine how pissed people would get being passed by you. :ROFL:

This.... This is a pretty good idea.

What, like a propeller hat?

https://www.miataturbo.net/attachmen...ine=1411667873

Go for the real deal. Spinners FTMFW!!

https://www.miataturbo.net/attachmen...1&d=1411669297

And connect batter LEDs to the spinning portion. Who needs ground effects honestly!

The big question is, if I angle the propellers slightly will they produce downforce or lift?

Best purchase I made INA long time was the leather bound collector series. I grew up on C&H. It was and is the best thing including The Far Side comics.

I have the same collection. Love it. It resides by my bedside almost permanently.

Spent the weekend hanging out with my niece and sister so I haven't gotten a lot done on the radiator cowling. I'm 50% done with it right now. Just need to:

-Enclose the sides
-Cut the plastic on the rear and bend the tabs to meet up with the fan mounts on the radiator
-Rivet the areas I plastic welded

Pinched area on the bottom is to add a little rigidity. Fit is almost too perfect, it is pretty hard to pop on and off. The good thing is that you won't ever have to remove it since I will be making the skid plate/bottom tray separate so if you need to get to the engine bay you won't have to remove the radiator cowling at all.

Looks a little rough at the moment but there is literally no where for the air to go but through through intercooler and radiator.

https://www.miataturbo.net/attachmen...ine=1412087423

I really like that Jeff.

I think I'll go ahead and order up a FAB intercooler (machine shop is finally working on the Silver car engine!). When will my IC/Radiator ducting be ready? LOL.

I use ductape, you use some kind of awsome material. :rofl: That´s not fair, you win sir :drool:;);)

Great work !

For you, I'd make one. I am using this one on my car since it was my "learning piece". Yeah, you won't ever see it, so superficialities need not apply, but I learned how to make it faster and involving way less labor. I bent things/welding the plastic in the wrong order making it more labor intensive than it should have been.

Revlimiter gets the second one, since I want to make sure he is getting a nice clean, no ugly bends/messy welded plastic, radiator cowling. It's amazing how many little tricks and techniques you learn by doing this once. I'm glad I decided to assault this project again, it taught me a lot.

(Really though let me know if you want one. I should have enough plastic to do a third as long as you don't want an under-tray as well)

:bowdown:

Template!....Template!....Template!....Template!.. ..Template!....Template!....

Dude I'd need to go to some shop that has a 3d scanner. That is the only way if you'd be able to properly recreate this. So many angles and variances in length.

I'd love to give you some measurements, but I don't think it translate well.

I am contemplating figuring out how to make a vacuum form of it though. That is mostly deducing how I would do it, rather than I will do it. In my minds eye I'd have to make it a 3 piece mold. There is no way to make a one piece, unless I carved it out of foam into a positive mold, and then used the plastic to make the negative. I'd have to make one big ass vacuum molder.

Plus, everyone has their radiator in a different place, some have AC still, different piping for intercooler. Just too much damn variance. Unless this forced everyone to buy a FAB9 intercooler from Bryan...which I'd be ok with since the intercooler is amazing.:party:

Wow. That's really generous. Thanks.

My configuration is different though. My radiator is still in the OEM location (I remember that you moved yours slightly) and the Silver car is a DD that has to keep functional AC. So, basically, I'll take inspiration from this. I've got a bunch of that plastic sheet myself to play with. Need to get a plastic welder from HF too (should come in handy given our propensity to nail coyotes and jackrabbits).

I love these build threads. Much cross-pollination of ideas. Our cars ROCK! :party:

No worries you've helped me out a lot over the course of this build man!

I too like cross-polination...:giggle:

OK I got the cowling all finished up and the bumper back on and I was going to upload some photos but some family friends came over and I haven't had the time to.

What I did find out after doing a bunch of autotuning to ensure I didn't have any lean areas, is that I have a weird sputtering issue when I am in high boost.
-It isn't overboost protection, since I'm only hitting a max of 270kpa(280 is my OB limit).
-It isn't spark plug blowout either, I pulled the plugs and they looked peachy @.36 gap.
-It isn't showing a lean situation with classic spark blowout/overboost activation. Instead it hits around 10+/- AFR.

Is this an OEM FPR overload issue in conjunction with the new injectors and 255 pump? It feel like really fast stuttering/sputtering hiccuping. It isn't a harsh interruption in power, just a soft interruption in acceleration, but it noticeably affects power until I lightly press the accelerator to slowly accelerate. Anything full WOT causes the situation.

Brian at Fab9Tuning provided me with a Fuelab 515 AFPR &FPR gauge(Thanks again!), which I haven't had a chance to install yet. So after installing I'm hoping it takes care of the issue.

My only thought could be Accel Enrich settings, but my logs are not showing Accel Enrich activating in the problematic areas.
