If you are to go with a 981 Cayman generation and intend on heavily tracking it, I would recommend an oil cooler, optionally an extended oil pan for more capacity and cooling.

Lastly, if my memory serves correctly, the aluminum cam bolts or alu bolts in a critical component of the engine must be swapped to steel. High rpm driving can vibrate these to such perfection that they can back out or snap and cause catastrophic engine damage. 987 generation Caymans don’t have this issue as they are steel bolts. Easy fix/swap. Source from multiple shops I’ve spoken to. I would double and triple check on that with a race shop that has extensive 981 experience working on them. Since I own an 987 this really didn’t stay in my long term memory but posts like this help me to remember.

If you were planning something more expensive, I would suggest a 718 GTS 4L 😂

Why haven’t you bought one already?

If it makes this easier, when there’s a GT”2” in the name, the 2 stands for 2 turbochargers.
