i am finishing up my light gsr build i got stock bore 81mm ctr pistons, skunk2 mani, skunk2 stage1 tuner cams, skunk2 cam gears, 440cc injectors, cold air intake, full exhaust headers to muffler, new bearings and rings, light weight flywheel, si tranny. what kind of numbers should i make untuned and what can i make tuned. what max rpm are skunk2 stage1 tuner cams good till.

 

get on a dyno... seriously. Nobody can honestly make an accurate guess as to how much power someone is putting down just by looking at mods. A dyno is the only real way to find out.

And as far as the cams go, my guess is the stock redline. Stage I cams don't require upgraded valvetrains, which tells me you don't need to rev any higher than stock.

 

i say more horsepower than stock
