I've got a ST170 on GSXR 750 throttle bodies, 4:2:1 exhaust, canems ECU switching the VVT at 1850 rpm (Not ideal, crude but all the ecu will do.)
I'm looking to make around 220 - 240 bhp around 7500 rpm with useable torque throughout.
I'm planning on getting the head ported and polished but aside from that..not sure which direction to go.
I'd like cams but not sure whether to go vvt delete Cat Cams or other options?
What CR do I aim for with what cams..and how to make it..head skim, block decked or aftermarket rods and pistons?
OR...is standard bottom end good for the power?

Has anyone who's built one with decent power got any useful advice?
