I have APS TBE with Cobb access port, need help with the next mod.:(

Thank you.

anyone??

im probly going with a fmic first then turbo etc. but thats only because of the amount of money my set up is going to be (6 grand) so front mount first for me

6G's worth of mods??


anyways i would get a VF-22 THEN a fmic..

FMIC, then 18G or 20G with supporting mods. ;)

If you get a FMIC on your stock VF39, you will feel a decrease in performance (lag, spool, etc). My advice to you is save your money and buy them at the same time so you can save some cost on labor, and you won't have a turbo on your car, that is making the TMIC heat soak under high boost. Why are you only looking at the IHI turbos?? They aren't that much bigger than stock and therefore won't make as much power as say a 20g or PE 1820. Hope this helps.

Go bigger with your turbo only because you'll regret the 22 later on. The 22 is a good choice for the WRX not the STi.

Sorry to inform you buddy, we just installed a FMIC on my friends STi and we compared it to our other friends STi and Man :eek: You can feel the pull is much harder by far.. now being said.. both cars have the same exact mods and ECU tuning.. Full boost comes on maybe 200-300 rpms later but, when it kicks in.., it just puts you in your seat. We did a few runs on the freeway and every time the STi with the FMIC pulled harder.. Do you, yourself have a FMIC on your car?, or are you talking from personal experience or from hear say? Because I am trying to understand where this decrease in performance is coming from :huh:

Sounds like your cars either have horrid tuning, or not running the turbo as hard as it can go.

From personal experience a FMIC can shave off 20WHP compared to a stock STi TMIC if the turbo is pushed as hard as it can go, with the usual I/H/E + EM.

i was running around with a Greddy FMIC on my stock VF39 for about 2 weeks and hated it the power was horrible, laggy and I felt a loss in TQ. I agree with XT6Wagon that a FMIC really does put you down on power over a TMIC.

Current AP STi maps won't work with VF22. What EM you going to use?

1) Under no conditions does an 'upgraded' IHI turbo make any sense on an STi ... waste of time and money for such a minor peak flow increase.

2) If you're going to upgrade the turbo, I really wouldn't recommend anything smaller than a TD06H-20G. 18G is possible if you don't have higher power aspirations, but you'll just kick yourself and want a bigger turbo soon thereafter ;)

3) When you do upgrade the turbo, you'll need at the minimum bigger injectors, fuel pump, and new engine mgmt with a good tune for it to all work properly/safely. FMIC is a good idea at this point too.

Without running a bigger Turbo it really is a waste of money. The stock IC works really well with the stock turbo.
Why do the guys running FMIC (with the stock turbo) run slower at the track? Because the stocker works better with the small stock turbo.

I've seen2 different STi's at the track with upgraded FMIC + bolt ons running mid 13s @ 103 mph or so. Thats a huge amount of money spent to run what a stock STi can run.

So take my advise don't upgrade your IC unless your planning on running a bigger turbo. This will save you a lot of money.

Thank you for your feed back, all your experiences are truly appreciated. For now I going to save more money to have the Turbo+FMIC+Injectors.

dont forget the EM!

Tell me that you tuned for the FMIC and I'll beleive you. Otherwise the crap VF-39 will not fill the fmic up quick enough and you'll get lag and you will see a decrease in 1/4 mile times. And yes I speak from personal experience.

But then I got a ECUTEK flash from kingpin and got that lost power back and shave a tenth off my time.

So with a fmic and a stock turbo you'll loose power on the bottom all things equal unless you tune for it. However, you will not experience the dreaded heatsoak/pulltiming/feal weak, like you experience with a TMIC.

WIth a good tune that makes use of the much cooler charge a fmic has you'll get that power back and then some. But you'll probably still be a little laggier with the stock turbo.

So put a green on and have your problems solved. :lol:

while i agree that a bigger turbo than vf22 would be a better choice for an sti, but i just installed a turboxs fmic that blk04 is talking about, and while there is some increased lag, the car pulls MUCH harder from 4000 rpm on, running the same tuning. i might get a bigger turbo later, but at least i'm ready for it. for some, it'll be tough to afford a turbo like a 20g, fmic, injectors etc at the same time. in the end, a fmic is worth it even w/ stock vf39, plus now i'm sleeper w/ the rs hood...

gotboost, a greddy fmic is so small, it's worthless as a fmic. it's probably only slightly larger than the stock tmic. thats probably why your performance decreased... all you gained was more lag...

What does your car run at the track? Dyno numbers? Like I mentioned earlier the fastest cars at the track (stock turbo) seem to be running the stock IC.
I really can't see spending all that money on a FMIC unless your upgrading the turbo and looking for big hp numbers.
Thats a lot of money spent on very little performance and more turbo lag.

No complaints with it at all, it handles the 20G quite well.

i'm not interested in drag racing numbers, so i don't know what it runs at the strip. in addition, drag times have a lot of variables- like driver skill. you could get a 12.7 one run, and a 13.1 the next run, doesnt say anything about your car... on road courses and autox, there is a difference, and on the freeway, i can feel a definite gain. I can only speak from my own personal experience. but yeah a 18g or 20g is a good turbo w/ a fmic, but i can tell you that the stock tmic suffers a lot of heat soak. on the track, the car would feel less and less strong as laps progressed (even with the IC spray), now repeated runs dont feel any different.

its not the time, but rather the trap speed that tells if you've gained power or not.

Anyhow, wrxmando... I say go with the FMIC, go with an 18G or 20G with supporting mods. Atleast you'll have the FMIC out of the way.
