Turbo Questions
i'm buying an 05 STi in a few weeks and i wanted to know a few things. i've got a list of parts i'm going to get for it. i'm not a newbie with cars but i'm not as familiar with turbos. i plan on getting the fp green turbo and perrin FMIC. my question is can i put those on with a turbo back exhaust, utec and a few other things or will i need to do more internal upgrades? i was planning on doing a few things and then big turbo and FMIC and then internals and suspension. i wanted to know if that would be ok or not? thanks!!!

The only problem I can see is that if you put on a big turbo and large intercooler (perrin) it will lean out the cylinders a bit. The WRX and STi are known for a cylinder lening out a bit more then the other 3 so I woulod invest in anew fuel rain and fuel pump. Maybe some new injectors as well.

I know this is gonna sound like it's coming from an old fart, but I suggest getting used to the car before changing out bits & pieces. This will allow you to establish a "base line" of performance. After a few months have passed & you've done your homework, open up the modding floodgates!

since youre getting an FP Green, FMIC, TBE and a UTEC I would get these:
Fuel Rails
Bigger Injectors
Fuel Pump
lots of Dyno Tuning by someone that is good at tuning the UTEC on an STi
