I ran the piston, sleeve, and crank from a VZR2 with a V-Spec carb, head, and turbo button with a P3 plug. The block, con rod, end plate, and bearings are the same for both. I ran it off-road in an XB8. It worked out prettygood because our track last seaon was low traction so I didn't need all the torque of the V-Spec. The combo I put together extended the top end way more. My buggy would run away from anyother car, period, on our 140' straight. I always like massive torque off the bottom so my favorite pipe is the Jammin JP-1. I could get 7 min. on 125cc. with the blue restrictor.

The VZR2 piston, sleeve, and crank will fit right into your V-Spec.

Too bad, I blew it up. It was spinning the tires all the time down the straight I over-revved it too many times the rod snapped.
