Prime Performance aka Prime Driven these days. They swapped a GEN 4 in one. You can also turbocharge the engine you have. I wouldn't bother 3S swapping it to be honest. Toyomoto used to offer a turbo kit for them. Relatively easy to replicate for cheap. 3S manifold, CT26/20 turbo and the rest are universal parts. Not hard to do. And cheaper like i mentioned.
