Thinkin of buildin a new cossie in the new year, and want to try a slightly different spec this time.
The last cossie had the usual stg3 bits: T34, 500 cooler, greens, cams, LOW COMP (7.5:1) etc. but this time i want as little lag as possible.

SO, i'm thinking of something along these lines: 200 block, balanced crank & rods, ported & polished head. roller bearing turbo (GT30?) with ext wastegate. The comp ratio is where i'm thinking of making the big difference, as i was contemplating raising it to 8.5 or maybe even as high as 9:1. I'm not sure on injectors or map yet, advice appreciated.
As i'm only aiming for 350bhp (but with massive torque this time) will this comp ratio be ok?

Please discuss: any help is brill, ta!
