I am looking to make around 500whp on a built ls/vtec motor with 9.0:1 compression. I am un-sure of what turbo/manifold to go with. Full-Race kits are expensive but I see 50trim kits on e-bay for like 700-1000 bucks.... t3/4 50 trim turbos....how bad are they for them to be so cheap? I was thinking of using the sc61 turbo. Any suggestions?
