I got my 92 ls motor into my 90 si hatch, and am kind of disappointed with the performance. I looked into Ls vtec, and it seems like a lot of money for not much performance. My friend has a complete turbo kit that he bought for his 90 rex, and lost interest. Its XSboost turbo, really shitty piping, manifold, injectors, oil lines and pump, and fuel pump. He told me he would sell me the whole kit for $400, but I dont want to build the internals. What do you guys think? Would I be able to make some reliable power with this setup on the stock internals, and is it a good deal?
