The 280Z we are converting is a 1975. I've always been a huge SU fan and though some may make a case they are not as dependable, I've not actually found that to be the case. In fact when something needs to be addressed on the induction side, I'd much prefer the simpler diagnosing and repairs of SU's. When set up properly you can forget them for the most part. The pluses are they sound great, tip-in response is more lively, and the car is much more fun to drive. Admittedly, I'm biased having, owned over 20 early Z's with L-series engines and worked on countless others. Long live the SU's!
