im looking into a z car for myself and im wondering what kind of quarter mile times should I be expecting with a stock v8 mod and leaving the rear end and tranny stock??

They probably have those stats over at Hybridz.org. That's a good spot for mods to the S30. Good luck.

I suggest you buy the V8 conversion manual for Datsun's from JTR. For a minimal price, you can learn all about whats involved and what performance can be expected from a V8 converted Z.

In the meantime, there are plenty of free online calculators that can estimate a 1/4 mile time based on weight and horsepower.
