a buddy of mine that just got back in the states from serving over seas is ready to upgrade is camaro. its a stock ls1 right now, other than an exhaust and a tune. well he is pretty hell bent on a turbo set up and a local guy has a 76mm, w/g, BOV, and a big air to air for cheap. all he is wanting out of it is low 11's, high 10's until he builds another short block. will the 76 work very well with pump gas (91) and lower boost levels? and if it will work out ok, what would be a good cam and valve spring choice for a 90% street car?
