if you had a SBC there is quick and dirty 350 throttle body and a JY ecm and harness. thats about the only cheap ready to go stuff, custom redux for a smaller engine -wether its MS or JY-gm is a steep learning curve, the gm stuff everone uses is the 88-91ish obd1 stuff which has a data stream about 3-4 times faster than the earlier gm stuff, there are guys didoing 4, 6 and 8 cyl stuff-and retrofiting to many other non gm engines--but it takes hacking the chip, opening the bin files and changing the values to fit the odd engine.
