Find a 4g64 wideblock and put the 4g63 heads on it and you have 6 more c.i., better torque, and should be able to make an easy 300hp with the right turbo setup and MSpnp.

Then sell the 4g63 short block and recoup some bucks.

The dohc 4g4 should handle 15psi on pump gas with the nice combustion chambers and 4v heads. I hear the gen1 heads flow better, and it seems you need the 6bolt block for best results. There are some water circulation mods you need to clear the firewall.

See projectzerog.com for all the skinny


OK so im going for it! I found a 91 4G64 block at mt local yard for 150, I have found the 4G63 complete head for 200$
I already have a nice header that I bought a year or so ago.
found a 14B turbo from a guy here in town so im after that as well. The guy with the Gen1 head has a full dsm 4G63 gen1 wire harness that im getting also. Now im trying to find which intake I should run as there is many options for diffrent setup's I have seen. Eddy what is the MSpnp mean? Map sensor or? These engines have alot of aftermarket parts
as well as tunner software...and the fun starts! <img src="/forums/images/graemlins/smile.gif" alt="" />
