can anyone tell me whats the difference between a normal wrx and a prodrive. Want to put the prodrive pack on my wrx and want to get all the right parts by the way its an 04 model

 

do you mean PPP ???? thats made my prodrive its a bolt on pack.

 

i know the sti ppp for a 04sti is a back box and decated middle section onli 2.5" tho and a uprated fuel pump and revisd ecu. i think the wrx ppp is the same with the adtion of a larger intercooler hose pipe. hope this helps. but if you want my opion don't bother with the ppp get a full remap and and 2.5 or 3" turbo back system and uprated fuel pump plus injectors and either a induction kit or element filter.

 

or a new ecu. i spoke to john pye 2day and he said a replacement sim tek ecu is awsume on a wrx with gains in throttle respons and overal drive abilty and better mpg
