Oil cooler will definitely be required for track duty. And yes, that is why your old stock Z could not handle the track.
Stillen Gen3s and Takeda CAI are the consensus top intake choices. Fast Intentions is probably the top exhaust choice. But there are cheap eBay exhausts that don't sound bad with good gains and there are expensive exotic exhausts that sound amazing with little to no gains. It sounds like you're going to have to base your decision around your budget.
Don't forget tires. Probably the most important performance mod.
