S475 / S480

I am seriously thinking about pulling the trigger on the VS 7875. There are a lot of builds on the ls forums and sloppy mechanics has had some good luck with their stuff. It should make more than enough, but you hear about high back pressure with the 75mm turbine and larger cubic inches.... Forced Inductions told me I needed to go t6 unless I like blowing head gaskets..... That sure gave me a warm fuzzy lol.

You thinking about swapping out your gt45?
