Forced Performance 20g question? Help...

Forced Performance turbo question...
I am planning to buy the Forced Performance 20G turbo....

Will I need a bigger injector then STI to run it at stock boost?

Is this turbo a true direct bolt on?

Am I ok by using a PDE 3 inch down pipe? or should I get the turbo XS 4 to 3 inch pipe?

This is my motor.

Stock JDM STI Version 8 motor.
Catless down pipe
Headers
up pipe
And walbro fuel pump....

Thanks....

PS.. If anyone is intersted in Buying a vf37 and all the stuff U need to bolt on to your car here U go...

What sorta boost are you planning on running with it. When you say stock do you mean 13.5? Honestly, if I were you I would upgrade the injectors. It can't hurt you to do it but it could if you dont.

i believe the 20G turbo is not drop in. think u might need a custom uppipe and a custom down pipe. since i dont they make a complete bolt on 20G yet. i have only heard of a few companies making a bolt on 16G.

u didnt state which on u wanted.

I suggest you call FP and speak to Robert. I have the FP hybrid and like it much. FP makes great products and offers better service. If the 20G won't work for you, maybe Robert will be able to direct you to something else.

I know there 18G is direct bolt-on so the 20G might be as well. On the 18G you have to keep the boost relatively low on the STi injectors so if you want to extract the full potential of the 20G bigger injectors would be best. Check out Ultimate Racing they have some 750s...these should be perfect.

the forced performance 20g that is specific to the wrx is a direct bolt on. i would run no smaller than the pe650's.

heres a photo of mine next to stock.
