is it possible to do a direct switch from a 4g64(96 eclipse spyder) to a 4g63 motor with not a lot of mods? cause the 4g64 is soo hard to find n e thing for and it seems that the 4g63 is even more powerful, and would that be a good idea to switch the motors?

 

Well the ecu's are different but besides that it should be fine. Motor mounts and all. Dont get me wrong its going to be alot of work but it can be done for say 3g?
