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. |
Thanks for info what is the injector flow rate on these? Sorry obviously don’t know much about them. |
My little brother has a wrx ppp that had no mods on it then I’ve put a forge dump valve and hks panel filter and a cat back jdm exhaust runs perfect no issues n9 lights etc sounds really nice aswell |

Dump valves don't need to be mapped in, and if the ppp is 265 on a wrx then that's your lot pretty much as far as the turbo goes.
