| Yet look over the last few years. 400rwhp Z's with stock turbo's rolling around with 90K+ miles on many. Many even have much bigger turbo's on stock long blocks and are doing just fine. The VG30DETT is incredibly strong. With correctly calibrated fuel, ignition and boost management, the engine is good for 500-600 streetable horsepower and that's a conservative number do to more is less over all life of the motor. Even the Supra guys will tell ya, 800rwhp on stock bottom is great, but they don't last long at all under those conditions and they must rebuild as well. It's all the true stories you don't see about Supra's blowing there motors as well under stress conditions Good reading on Project Z motor rebuild compared to stock. [ http://www.sportcompactcarweb.com/projectcars/9909scc_proj300zx/ ] These engines, like all Nissan engines, are extremely well built. The twin turbo even had oil squirters to cool the pistons! The engine has dual overhead cams, a main cap girdle (I piece main cap), high nickel block, forged crank, and forged rods. Just the maintenance of pulling a motor, adding bigger bolt on's and if something where to go wrong, which happens to even built motors. Then repulling will make you bitter of the car and possibly sell it. Also, a street engine lives 90% of its life at - 2000-5000rpm range. Higher the Rpm's more stress on internals, more wear. Driving the car will not kill the car as we all know. Dumping a high demand of stress and Torque on it such as a drag racer will have you doing just like a Drag racer crew does, rebuild after rebuild. The VG motors are hailed to being one of the finest motors ever ( of it's time ) to produce such power and not be open to do it ( just bolt on's ).
