The stock 3000gt vr4 turbo exhaust manifolds bolt directly to your heads. That's the easy part. Then you have to route oil feeds, oil returns, intake pipes, intercooler(s), install larger fuel injectors, find a way to control the computer to compensate for the increased fuel, larger fuel pump, make an entirely new exhaust after the turbos. It's on my bucket list, but I was just being silly suggesting it for a solution to your problem.
