how could I get more power out of my my03 wagon with ppp fitted? Would I need to get another ecu? Thinking of circa 300-350 reliable bhp? What kind of money am I talking and whos the man to do it (south east)???

 

You would need to sort the gearbox, clutch, brakes, ecutek the ecu, bigger turbo, uprated fuel pump and oil pump, your not talking cheap though, a set of 4 pot ap brakes will set you back 1300 quid, gearbox rebuild will be 1k+, clutch will be 4-500 quid, ecutek will be 750-800 quid, turbo will cost around 700 quid, then add labour, but for 100% reliability you would need (350bhp) an engine rebuild (2k+).
Check out places like roger clarke motorsport who do upgrades. (it would have been cheaper for you to get a JDM STi for what you will theoretically be spending).
