I believe so. I see different engine designs in their gallery. Best to call and ask. http://www.hip-designllc.com/index_product1.html
I was washing my (dark blue) Cayman yesterday, and I was thinking about how if I only had two garage spots for the rest of my life, the Cayman would be the car I would keep. That and my E400 wagon. But the Cayman can do it all-- fun in the twisties, fun on the track, reasonable as a daily driver, and you could even take it on a long trip and be perfectly happy and comfortable.
Just drove both literally back to back this morning. Different generations so not the best comparison. I find that the Cayman (997) is a bit more balanced. In almost every way comparable to a 991.1 Carrera S. With that said they are both incredible cars. I plan to keep my current GT3 forever!
