NissanZ34

I read somewhere an unofficial claim that said they are pretty much maxed out at 700whp and 600wtq. They don't last long with that much power. It is safe to assume if you stay around 500 whp and 450tq it should last a good decent amount of time.

Now if I had the money and intended to go forced induction, I would do supporting mods first such as exhaust, clutch & flywheel, big oil cooler, motor & transmission mounts, differential brace, differential bushing and a tuning license.

Then I would have the motor built from the ground up or at very least pistons and connecting rods. Get the injectors and fuel pump along with aftermarket fuel pump hat.

Then I would get the turbo kit and the remaining needed parts.

Proceeding in this order will insure you to do it only once.
