It's generally agreed here that it will produce tons of lag and is not worth it on a stock turbo.

dont listen to everything that people post. I am running a FMIC on my stock td04 stage 2 19psi and the only lag I get is the beggining of 1st gear and only 2-300 RPM's after that its all go and it hits hard. People make it seem like its a bog monster if you put a FMIC on it. I am fully catless so it does help spool up alittle bit but really, the lag is not that bad.

i believe the stock td04 will not take advantage of the fmic so therefore a big tmic would be better, but hey its your car so do what you like. and i agree, FMICs look awesome

The front mount design is over kill for smaller turbos. 8 feet of plumbing to the intercooler, plus an intercooler that is probably too large for the application... but if you want it for looks then buy it you wont be disappointed with the look. If you want performance on the stock unit or even a vf39 buy a better top mount. Top mount has the advantage of shorter plumbing, and on subies, a hood scoop molded into the car for that purpose. Plus if you live where there is snow your intercooler wont get damaged by ice/snow nearly as easily.

Turn up the boost is the secret.

I ran 22+ on the TD04. It tapered to all hell but, it was fun.

And all FMIC kits are the same?All use the same charge piping sizes,all use the same IC core?No.Different people have different results because they use different kits.APS makes two FMIC kits.Do ya think your gonna have different results depending on which one you use?Do ya think if you don't retune you might see more lag?

You are far from stock with stage two. Furthermore, while your anecdotal evidence sheds a dim light, most of the posters on this board agree that a TD04 performs best with a high quality TMIC.

Read Unibombers manifest hes was running in the low 20psi's, its all in the tune and supporting mods. Once I get a GM bcs, inj and a fuel pump maybe some meth/alky shes going up to 22/23psi. People under estimate the power that is to be had with their stock turbo. Also if it blows I can pick up a used one w/ 5k miles for $100 off ebay.


hahaha islander.....anecdotal evidence

by jove dear Watson

A stock turbo also perfoms best when you port it or run meth or alky or port the cross pipe or or or or or...the topic of this tread is not what will make it run the best the Op is only wondering about lag associated with a FMIC vs a TMIC. Also the OP never stated his car was stock only that he had the stock turbo. You stated that running a FMIC caused "tons" of lag, I mearly responded by saying yes there is lag but not nearly as bad as people make it out to be. Will it perform the best with a TMIC, maybe but if anyone wants to take a ride in my car I will be glad to show them the amount of lag or go for a spirited drive w/ someone running a TMIC.

i ran a stock turbo on my front mount for a while, The lag was there. To me, it's not worth it, but each man to his own.

I ran a large APS FMIC with my VF30 for over a year. It kinda sucked, a lot! the lag was a little worse but I could live with that. What downright sucked was that at WOT after every shift, it would take ~1.4 seconds(logging shows this) for the turbo to repressurize the piping & core back to 20psi. After a shift, the engine is still running ~4000RPM and climbing and you gotta fill up all that tubing and core again. It seriously sucked.

Once I threw in a 8cm FPGreen, that issue went away. Lesson learned... Match your turbo to your intercooler.

I'm running stock turbo and IC and I"m running 17-19psi on my TD04. Of course Clark is a mad man when it comes to tuning. You can use a FMIC if you want just have your car tuned and the better the tuner the better the car will act. Don't use a ots map and run a fmic that's not smart. And running a FMIC on a VF series turbo can be done too..... for example: All the subie rally cars are running either a vf-34 or 43 can't really remember off the top of my head but they all are running FMICs

If your talking about the limited v mount that sits in the grill instead of the bumper I believe they had that last year but looking at snow drift highlights it looks like they went with a IC that sat in the bumper this year. Kinda like the greddy spec v. But that is neither here nor there.....

The main thing I was getting at was using a FMIC on a vf series turbo or even a TD04 the only draw back will be lag and if you can deal with it then I don't see a problem. You may get a cooler charge plus if in the future you decide to upgrade turbos then you already have a fmic and that's something you don't have to worry about. That is actually my plan, Greddy spec v FMIC on my TD04 then a little later downt he road find a VF-34 maybe a 39

i guess what we are trying to get at is that a decent top mount is definately efficient enough for a td04 and even a vf series turbo, and for the money you could just stick with a bigger top mount and have some change left in your pocket.....so it just seems pointless to go w/ a fmic unless you just want it to look cool in which case yea you can do it...get tuned for it....and hopefully the extra bit of lag wont bother you too much

Also depending on which part of the world your in kinda helps too. CA, OH, anywhere about just north of Tenn a good TMIC is great. Sadly enough down here in hell when you have your IC sitting in your engine bay and its 110 degrees with 60% humidity......it blows

Well considering we've seen a loss in performance up until about the FP20g size turbos. The BEST 1/4 mile run I've seen with a FMIC + stock TD04 was 14.0 et and I forget the MPH....

I ran a 13.89 STOCK....

I actually have a close friend who HAD a similar setup as me, intake, FP18g, Walbro, PE650's, Catless Turboback, GM BCS. Only difference is he had a TurboXS FMIC and I have an STI TMIC. He dynoed about 15 more AWHP then me. But I could walk him at the drag strip, best run he could make was 13.4x. We switched cars and I could instantly tell the car took a second or two more to build boost (a second or two makes a huge difference if you are racing for fractions of a second). Eventually he went with an FPGreen, and the FMIC is a great combination with it...

Here is a good example of a FMIC hurting performance...and its on a vf39 (larger turbo then the td04)...

http://forums.nasioc.com/forums/show...ghlight=cobalt

There is even a video at the end of a Cobalt SS walking that STI. You can watch him drop off between shifts....

What I'm getting at is the is NO benefits of a FMIC in combination with the TD04. As even the stock intercooler can peak 19 psi without heat soaking, on the STI its easy to get 19 psi (my turbo didnt make power after 18 so I left it there when I had the TD04). Its only going to hinder performance.

Heatsoak is suxors. Get a FMIC, but don't get huge ass piping. Keep the volume lower and you wont notice lag so much. I got a FMIC cause in Idaho we have massive hills that keep me at 20%-30% throttle. 15 minutes of boost has a way of making a TMIC HOT.
