Thanks to everyone for all the help recently. I was hoping someone could answer me this.
If I have a 2002 WRX stock, what happens if you replaced turbo, injectors, intercooler and fuel pump and tune the vehicle, but leave the Downpipe stock?
I know that doing DOwnpipe and Tune can give some good gains, but what about leaving downpipe and just doing a turbo upgrade.
I only ask because I already have my injectors, pump, intercooler and was planning on selling the parts to do the DP, but i then thought, what about just doing the Turbo upgrade with a VF39 or similar.
Will I still see good gains?
