hi, I want to do a turbo upgrade on my 2004 wrx, can I get some help on what would be good? Im looking for spooling at 3.5k rpm and about 20psi. What do i need besdies the turbo and front mount intercooler to make this happen? and id like my 0-60 to be about 4 seconds, 1/4 mile 12 seconds.

 

There are lots of things for you to read in here that will get you to your goals, and you are breaking a primary forum rule but Im going to be nice because it is your first post.

Get the FMIC thing out of your head.

You can easily attain your goals with an 18g XTR some 1000cc or larger injectors, a down pipe, an up pipe, a turbo back, possibly an intake, a larger TMIC, and a tune. Either open source, or an AP, and run E-85.........if no e-85 maybe meth.

Good luck and happy hunting.

 

To reach those goals I would suggest an 18G turbo, STi TMIC, 650cc Injectors, 255lph fuel pump, 3in catless/catted turboback, meth injection, and a good protune via opensource. Maybe an intake.

Keep in mind most of the goals you listed mainly depends on how good of a driver you are as well. You should search for some setups others have to see what suits you best. Searching can be your best friend.

 

Talk to the person who will be tuning your car, they will have thought out plans for you to achieve your power goals. Before you build your car, you may want to consider if that stock 5 speed will hold up to those power levels and driving habbits. My last 5 speed didn't like what you're about to do to your car.

 

For a 2.0 I would say either a Evo 3 16G or an 18G. Anything else is absurd for a 2.0 unless its built.
