Hello guys, this is my first time posting on a forum. I bought a V8 stock aluminum block 5.7 LS1. I'm dropping this engine on a 350z drift car with a t-56 6-speed trans.

for the turbo I'm looking to go for the 76mm ball bearing cx racing single turbo.

what size wastegate to i need? and why
what king of blowoff valve you guys recommend?
how much boost can i push maximum?
how much horse i could make.

im also doing this intake manifold in the link below. what do think of it, is there a better one

please advice, thanks
