Being guided by those who are running / have run some nice hp from k04 turbo's.
Sort of hoping with the new injectors / pro4 mani / flowed head that I can ease off the boost but raise the hp to match torque. Too much at mo to up the turbo size.

The bigport head will help with flow once you get the boost up
On a stock 9.5:1 AUQ lump with a hybrid k03/k04 I made 280bhp and 290 tq at 1.25-1.3 bar; changed the turbo for a GT28RS modded to fit the stock manifold and made 310bhp with 300tq at 1.3 bar. Biggest difference was the boost staying to the limiter at 7200
I could've pushed it to 330bhp @1.5bar on that setup but that was still running the stock fuel pump, LCR 370cc injectors and a 4bar fpr.
Keeping an eye on this to see where you end up with it, the car looks fantastic! Jealous, just a wee bit
I've got my old engine in the garage, I keep looking at that and eyeing up my wife's 400...
