Nah it has a D16A6, i know he was looking into putting a Z6 head on it but i believe compression was going to be too high. He did rebuild the D16A6 with P29 pistons and a thinner headgasket which bumped the compression to 11:1. Also has a ZC/SI hybrid tranny, with ZC 1-4th gears for very short gearing, and a SI 5th gear and final drive for lower highway cruising RPM's. Car runs great and is very strong. The best things is, it even has A/C haha.
