Good TMIC FAQ.

I have 07 STi and have access to buy JDM V7 STi TMIC, are there any fitment issues? Do I have to buy anything to make this JDM TMIC work? hows my shroud and splitters?

Yes, as long as you get the Y-pipe that comes with it. It will not benefit you by itself, especially on the stock turbo.

be prepared to fabricate y-pipe (coupler) and you also need a longer throttle hose if you want to mount it correctly...

Good Info. I just dropped in a USDM STi tmic in my wrx 2002. I had to get some longer hoses in order to get it to fit properly.

Did you need anything else for the swap i was thinking of doing the same swap on my 06 and do a new intercooler hose kit (http://www.rallysportdirect.com/shop...it-p-3674.html) ? or does it mount right up

2007 STi & WRX BPV gaskets are different!

I swapped a '07 stock TMIC for a '07 STi TMIC this past week-end, and the stock gasket has changed. A thin "rubber" gasket is used instead of the wide "paper" gasket. Also, the stock BPV flange has been routed to hold the new thin gasket in place.

Solution: go to an auto parts store and buy some "paper" gasket, and cut out the pattern for a new gasket!

Would have made this a new post but I haven't posted my 3 legit replies yet...

I've searched all over these forums as well as the general web and I can't seem to find a straightforward answer about what to do with the IC water tank in the winter time. Three questions come to mind:

Should the water be drained from the tank to avoid possible ice expansion damage to the tank, or can the tank be left half full to compensate for the expansion?

Should the tank be drained completely during winter months?

Should antifreeze be added to the tank (is it safe to do this)?

Advice appreciated!

I would consider using something to drop the freezing point of the water (such as antifreeze, but wouldn't use antifreeze)

And don't use anything combustible. But seriously wintertime, there shouldn't be need for I/C spraying, so in all reality I would probably drain it or use er up and not fill it until temps warrant the need for it.....

Your owner's manual has your answer on the IC water spray. It says 1/2 full tank = good times. Using your IC water spray in the winter is lunacy. Adding anitfreeze is lunacy.

I know it's a dead company, but I picked up an M2 TMIC
Finned area dimensions: 16.5" x 6.5" x 4.5"
Overall: 16.5" x 11" x 4.5"

Seems they had a bigger version also:

Post Is it worth it???

Everyone keeps asking about the fit of upgrading their non-sti tmic in their wrx for an sti, but if the user has very little modifications done to their car, is this a worthy upgrade?

I have the opportunity to purchase an sti tmic for cheap, but was wondering the benefits of doing so if I only have upgrade the uppipe and downpipe?

Just a green horn looking for guidance...

Yes, but you need to tune for it. The stock injectors will be the limiting factor after that.

Look at TurboXS stage 3, that's exactly what I have.

Tube & fin is not accurate enough. Apparently there are three types: extruded tube & fin, folded tube & fin and plate tube & fin.

See this article: http://www.are.com.au/feat/techtalk/...e%20and%20Fin?

Bit chaotic, but has a wealth of information.

Based on the pictures I determined that stock LGT tmic (and thus 08+ WRX) is folded fin & tube design. Must be the Subaru's Nissan heritage. Supposedly very efficient in terms of cooling but having significant pressure drop.

You own a turbo car. There is no reason not to cool the air as much as possible after the turbo heats it up. I'm sure with a stock wrx tmic, there's a lot left on the table in the cooling dept. Swapping to a larger STi TMIC along with respective sti scoop/splitter on top can't hurt. And no, you shouldn't need a tune for that. In fact re-tuning just for such a minor mod would be a bit silly.

I've never seen a factory turbo car with a completely efficent intercooler setup. In fact most are very insufficent. Talk about wasting HP.

There is a reason: bigger turbos have a larger pressure drop; you have to balance that against any gains you make, and frankly, if that's all you do, I doubt it's worthwhile.

Cooling is one thing, but especially without tuning (which is vital in my opinion, but definitely not required) the difference in throttle response and some spool may not be worth it for many people. Sure, you'll make a little better peak power and have more consistent IATs, but there ARE side effects.

I know from my own experience the difference on a well-tuned stock turbo of the stock and an aftermarket SSAC TMIC (tuned for the stock TMIC). I lost a few hundred RPMs of spool and there was quite a decrease in throttle response and spool-up (not the RPMs, just how fast it builds boost). In my opinion. Based on my experiences, I'd wait until A. It was tuned for or B. I had a bigger turbo, before adding the larger TMIC.

I'm not saying it's not beneficial, I'm just saying that there IS a downside, and from my experience the pros don't outweigh the cons from my perspective.
