Wrx 2003 PPP

Hi guys im investing in a 2003 wrx that already has PPP. My question is part of my enjoyment is modding well it was when I had one years ago. Is there much I can do to the car performance wise considering it has the 265 ppp already. Am I safe to put a dump Vallve on etc. Any other new performance add ons since 2003?( safe ones) regards Dave

The TD04 turbo you've got is already close to it's top limit, so for any significant power gains you'd have to change that, injectors & fuel pump.
Personally I'd go for some sti wheels (with decent tyres) and brembo brakes, thicker rear arb and drop links, some new suspension and geo set up, group N engine and gearbox mounts, braided hoses, brake stopper, sti steering knuckle and poly steering rack bushes. Then a smattering of poly bushes as the need to replace arises.

my standard wrx 03 injectors were near max duty around 320hp. that was obviously after a change of turbo but back in 2007 . think they're 440's. sti pinks are 550's
