Twin Turbo LS1 Question I've been entertaining the thought of a low boost twin turbo SBC in my 68 Camaro, and have decided to go with the LS1/T56. I already have two 87 Buick GN turbos sitting in my shop that I plan to use. My goals are to have a 550rwhp set up. Can a stock LS1 handle what I'm trying to do? I'm not sure what kind of boost I'll need on a stock motor to achieve those numbers. Any suggestions?
I run APS twin turbos in my LS1/t56 Trans Am and dynoed 548rwhp and 513rwtq. The bottom end is all factory, I changed the oil pump, cam and chain while I was in there and have had a blast. I use the stock #8 spring in the wastegate so 8psi is all I get. I figure there will come a time when I will have to replace the motor but for me cast iron is the next step. Go for it!
