Done right, Hondas are a force to be reckoned with. My buddy is going to be building a CRVtec (2.0 block B16 head) for his Del Sol. That thing is already pretty quick, I cant imagine it with 25% more displacement, 11.5:1 pistons, some nitrous, and some wicked cams. Also, my buddy has a stripped and gutted older hatch slammed to the ground and a D16 (SOHC Vtec). Even though its not much and all it has for performance parts in I/H/E, he still manages IIRC like 13.6-13.9's in the 1/4.
Have you figured out what you are going to do with that mitsu 1.8? Going to run a turbo setup in there or ditch it for a Honda 1.8?
