Yeah those DOHC motors can fly for sure. I built a Integra type-R Motor for a buddy of mine and he was running 11's on motor. He couldnt even use a 5" tach, he had to run one out of Busa! I think redline was around 12k.
Those guys drop some serious money in those motors for not to much GO ont he street. You almost have to run slicks on the front of those cars with 400+HP. It isnt even fun after you have to do that. My buddies Motor and
trans build totaled up to about $35K and then he blew it up at the track! LOL He should have bought a Mustang!
