Hmmm...How about a Air/Water Intercooler, or other aftermarket options?

[Etos]

Here is another thought of how to get a larger than stock Intercooler in the 818:

Perhaps a large FMIC could be mounted above the transmission behind one of the grills at the rear of the car. Several fans could force air over the FMIC (now a RMIC I guess) with air ducted from scoops at sides (or a WRX style hood scoop over the vent on the deck vent?). Looks like there might be enough room for the RMIC brackets and plumbing.

Happy Holidays!

FMIC does not mean it's a better intercooler. All FMIC have the inlet and outlet on the sides- it would create 2 90 degree turns the way you described it. If the placement is good- the TMIC is still a much much better fit. All you're doing is moving the TMIC back a bit to be further over the trans(factory TMIC is already right over the belhousing).

Also I think alot of you are over thinking this a bit. A factory STi TMIC is good to about a little over 20 PSI. After that the metal crimps start to pull away. Here's a thread with quite a bit of detail about it:

Regardless, at 20 PSI in an STi with a few bolt on items(TGV, turbo inlet) you are making 380HP easy in AWD. That's 460 crank, that's 400WHP easy in 2WD format. Point being is unless you want over 350HP in an 1800lb car a factory intercooler is more then enough. At 350hp you have a 5.1 P/W ratio. That's better then ZR1 P/W.
