So heres my dilema, i have 1000 bucks to drop into my 05 STi. The Problem is that I dont want to void my warrenty (dont Ask) so, what should be on my to do list of upgrade parts. I was thinking the Turbo XS utec and in a few years move to bigger injectors but that ecu will void right so what should i do???

 

try looking into the cobb acessport. It is nice because it is untraceable. when its time for service just switch back to stock.

 

A turboback while keeping the stock converter will still void correct?

 

I'd go with the Cobb or a good set of guages. They won't void your warranty and it's a good thing to start with. Learn your car while it's stock.

 

already have the factoy gauge pod and i think im gonna go with the accessport, i was alreadly looking into that thanks for the help

 

In a non performance sense, get a clear bra for your front end. The bra will protect the paint from road stuff. You might also consider kartboy shifter bushings (both front and rear for a firmer shifter feel) and whiteline steering rack bushings. If you plan on doing your own oil changes I'd also pick up a fumoto valve. While none of these parts will yield 20 extra hp, they will make a difference, not to meantion the fact that I believe are warrenty friendly.
