I'm trying to buy a throttle body and came across a skunk 2 70mm throttle body for $200. I've got a golden eagle intake manifold. Do you think there is any problem with using the 70mm sizing throttle body going onto a 64mm manifold?

 

save your money unless you are going to bore the IM to match.

 

Port matching is not hard to do....i vote you buy the tb. Proven gains. Skunk2 however has a common problem of the butterfly sticking. Apparently many members on these boards have lost their engines to this problem. I picked up a holley tb but omni power has been recommended. Apparently they have an almost stock like butterfly. Seemless opening and does not stick.
