Anyone running a big TMIC on a Stage 2 STi?

j87w · 12-30-2006, 12:01 PM

I have searched around here, around nasioc, and around clubwrx.net and I cant find any dyno sheets or advice from people that have added a big TMIC to there STi with a Turboback. I have read the big TMIC thread and SOG said a guy dropped a few tenths off his 1/4 mile from one. Im looking to put the APS one on for a stock look and good fitment. Anyone know of power gains with just a Turbo back exhaust and tuning (stage 2 pretty much)? Im not looking for advice on other power adders really just a new TMIC. Thanks

You need to get a custom tune. A TMIC any bigger than stock really throws things off if you're running a base stage not intended for a certain mod. St2 is supposed to be for TBE only. ONLY! Why? Boost in particular along with timing need to be reconfigured. I ran a bigger TMIC on my old bugeye and had problems until I got new map. I tried what you are asking. It was faster, but the TMIC affected how car hit boost. How much and how long. Not a good thing.

Well I'm actually going to get tuned. But what I meant is an STi with a Turboback and tuned plus the Big TMIC. What are these guys gaining out of the TMIC. I totally understand the maps and what it requires to run them and what not to put.

I ran an APS SR375 Tmic for a while. From my experience the APS unit flows much better than the stock unit. It is a bar and plate core so it should flow much better. If you combined this TMIC with some meth/water injection you would have a good platform for some insane torque.

I have recently taken mine off in anticipation of getting a FMIC so if you are interested let me know as I will be looking to sell it.

If you are just wondering what gains when properly tuned, you Should see 20whp easy. Little, little lag on the STi . Nothing like a front mount. But gains are very good w/ a large tmic. Problem is heat soak and future turbo limitations. Have been in 2 STi's w/ Spearco tmic's /vf39 and insane hit of torque.

I'd be interested in that too, let me know when you're selling it.

Are you using the stock turbo still? Keeping a FM combined with something like a FP2006 has been crossing my mind lately...

Does anyone have dynos they can post up with pre and post aftermarket TMIC upgrade?

Start skimming thru the Dyno Database sticky Dyno Database - Enter your numbers here! and look at item #10 of each post which is the TMIC or FMIC. I only looked at the first page but found:

1. 2004
2. 245WHP 93 octane
3. 253WTQ
4. 320WHP 93 octane
5. 360WTQ
6. CAI w/ Perrin turbo intake tube
7. Random Tech. catted 3"
8. Random Tech. 3"
9. ECUTEK
10. Turbo XS TMIC
11. SS @ SOG
12. Dynopack
13. Gwinnett, GA
14. Perrin EBCS, AVO auto. water sprayer, Turbo Smart Dual port BOV,Walbro 255
Latest 1/4 mile time was 12.465 @ 107.6
And a best MPH of 109 w/ a 12.7@109.01

I know that the bigger TMIC is a good way to go and the el cheapo ebay versions have been popular.....even on cars being raced in autox. I plan to slap one on right before I get tuned.....

Thanks Karl, I have looked through that thread a few times. I guess Ill just go through and find all of them to see if there is any results. The reason I started this thread though was to see if anyone had there Stage 2 tuned then put on a TMIC and had it retuned. I was just looking for gains with it. But Im going to look through that thread..

I know Scooby South posted in there with the stock TMIC and came back later and tuned with an e-bay special and got more HP & Torque.

I'm running the APS SR375 TMIC as well, but on a 20G setup.

It has proved to be efficient when properly cooled, and is definitely an upgrade from the stock unit.
