hello i have a 2001 wrx which is pretty standard apart from an exhaust and air filter just wondering if changing the standard intercooler to an sti one is of any benefit and is it a straight swap like all the hoses fit straight on, i have done a search on here and couln't find any clear answers thanks in advance daniel

Unless you're going to have it remapped and possibly fit a larger turbo I think the standard WRX one is adequate.

I doubt it will make any difference without a remap (although I seem to recall someone posting that they experienced greater lag when they fitted one prior to remap).

thanks for the reply i will leave the standard one on for now,thanks again daniel

Btw, I forgot to add... I'm not a mechanic or anything, the above is just my viewpoint gathered from reading scoobynet and other car related bbs's for a couple of years

I may be wrong, but iirc the bugeye wrx TMIC isn't as efficient as the equivalent blobeye>, scoop is certainly smaller. In fact, the blob wrx scoop is as big/bigger than the bug STI..!

As far as fitting an STI 03> TMIC to any newage WRX, it's a piece of pi55. Although you also need to fit the matching undertray and scoop (block of flats..) to get full benefit.

As far as mapping is concerned, IMO it's not essential, basically your charge temps will be lower (like driving when it's cold) and that's should be within the ECU's capability. Mapping after may allow the mapper to use a bit more advance, but then again might not.

Try fitting (easy) a temp sensor in-between the IC and throttle body and monitor you charge temps for a week or so, then decide. K-type thermocouples are cheap and a half decent display ~£20 from the right place..
