No, I forgot about that. It has a CNC ported head with over-sized valves, but we didn't really see a significant gain from that (We Dyno'd it before and after). Maybe that would be more beneficial with the GT42 turbo (would probably do 650-700ATW with that).

However, it is still amazing to drive and very responsive, so it's likely to stay as it is.

Running it on Race fuel is almost a certainty though, just to see what it will do.
