red line 8500 ... so you'll be normally accelerating to 8000 rpm? With a high rev motor, to avoid delay in acceleration be using high-ratio final drive (example: 4.875) and a close-ratio gearbox

So with 1.3 liter, 8000 rpm you'll be making what? 120 bhp n/a, 160-180 bhp turbo'd (and less in rwhp)?


Just guessing here, but maybe the 2JZ turbo would be good spooling, although less max HP. It would boost mid-RPM torque, then the wastegate would come on before your redline

Large turbos, so to minimize Lag on the street they are fitted to large engines:
* IHI RHF5 - GTI Golf MK6, 200 HP
* garrett Gt2052, 225 hp
* TD05HR-16G6-10.5T(evo 6), 276 HP
* garrett GT2554R - up to 270 HP

small
* 2jz CT12b: 3-liter, twin turbo 276 hp
* garrett GT17 - 130hp?
