With a big cooler like the Peron, Revo intake, a BBT k03 hybrid and that RS4 valve, I should see 350bhp.
Injector wise, I'm not sure. I've seen quite a few graphs of the BBT k03 mapped by R-Tech on the standard k03 injectors, and they all make good torque across the revs. I'll speak to Niki and see what benefit, if any, there is to k04 injectors.
Already got an uprated Helix clutch which should be good for 400lb/ft, and the Powervalve, so I'd like to think the big costs are out of the way engine-wise. Apart from the turbo!
