I've had a stock tune done a while back but I'm now wanting to get a bit more out of it whilst retaining the stock turbo.
Thoughts so far are;
HKS downpipe
Turbosmart kompact BPV
Grimmspeed 3 port solenoid
Intake pipes, maybe some jacks-GTB ones if he still has any left
And handling;
white line front and rear sway kit 22/20mm
STI pinks springs
Thoughts on this? i know going 3 port and intake pipes probably aren't needed at this level but would there be any noticeable gains from having them?
