Realistically speaking, how much power could the stock Z handle?

You will get mixed reviews about this. Over the years of seeing other people’s misfortune on their Z’s and seeing/helping with tear downs I would not do anything more than 450-500 whp and 450 wtq with a spot on tune from a reputable tuner. In alot of the cases I have seen the connecting rods were the limiting factor. Longevity really depends on your right foot and how your Z was tuned ultimately. It is all in the tune so when trying to push the limits of the stock Nissan pistons,connecting rods,crankshaft is opening Pandora’s box really you will be putting wear on other components as well. A good clutch kit and the CSC fix is a must. I have seen engine failures at 300 whp and 470 whp etc it just depends on how you use you’re Z the strip,track,auto x,autocross events really beats on your Z. Doing all your general maintenance on time is also key to longevity/dependablity on our cars. I would be more worried about damaging your engine than your transmission honestly. Our manual transmissions will take more abuse and whp/wtq than our automatic transmissions.
