I've got a white 03 si and i have my ups and downs about it. The ups are definately about the interior and how nice it looks. The downs are the performance aspects of the car. Its a fun car to drive and all and handles like a dream with just stock suspension....but i just need more power in this thing for me to be happy. I've got dc headers, greddy evo 2, injen CAI, and about to get the hondata upgrade. I'd rather go all motor with it instead of turbo. I would like to turbo it and all but i dont know. From someone that has already done it or knows exactly what their talking about....what would be the price range and power gains from some new camshafts and new internals of the engine. And also what would be the price range on a cybernations turbo kit and other mods to my car i'd have to do if i got the kit.

 

I wouldnt do camshafts and internal work...The best thing to do would be to get ahold of a type s head and swap it out, that plus your already getting hondata would make some very good #s. The only problem with that is that the type s heads are not readily available so youll have to spend some decent $. For the price of a turbo you can pick up a whole type s swap and then sell your motor to someone with an ex.. I read somewhere on an import mag. that featured the rev-hard ep3 and it only made 200hp.

 

If you want to go all motor, you should swap out your k20a3.

the man speaks the truth.

 

k-pro, bigger injectors, jrsc, race header, and some dyno time. = ~230whp

 

go with the k-pro that way if you want too add stuff you can tune to what you have on your car but you best bet is to wait a bit and upgrade you exhaust to 2.5 and go from there

A K20A2 swap should definately be in the plans for the future, at least in the meantime, scrap that shorty header and get a race header.

 

supercharge it , the jackson racing sc makes NOICE *** numbers

 

swap it for a k20a and slang your a3. cybernation stage I goes for about $4600 I think.

 

rev hard kit is pushing around 240+whp.
