The 35th Anniversary Z®’s engine has been modified using revised pistons and camshaft and the addition of electronic exhaust valve timing control.

Responded to similar post as well but I talked with Nissan Competition to find out what parts are different and was told that the difference is all ECU tuning, otherwise the motors are the same.

I don't think you can add exhaust valve control with an ECU change
There must have been a physical re-routing of timing belts to accomodate the new function

I was told almost all of the 13hp difference was the ECU tuning, so yes I know it has an exhaust valve control but according to Nissan Comp, its not worth anything HP wise, maybe 1-2.

Probably the reason why it is "mostly" ECU tuning is b/c they had to retune it for the VTC on the exhaust cam. So I bet the VTC on the exhaust help a bit. They also mentioned that it has revised pistons.

Well, take it anyway you want, but when I talked with Nissan Competition, to find out what parts I needed to update my motor in my racecar, they said it was all ECU tuning and that the new engine parts dont really add any horsepower. So in other words, I was ready to spend money and buy parts and they said dont bother....
