okay i have a 86 na shell with 30k on the body never seen a winter always stored inside(engine is toast overheated by previous owner) i wan't to do a 20b swap with a larger single turbo and get in the range of 6-750 hp. my brother says to do a 13b turbo and get the same hp with a big turbo. (note i am a mechanic by trade and i like the rotary and brother is a vw nut.) i just want the car to be able to do it and be somewhat reliable. i am going to do the majority of the work myself since i have the tools i just need the info for the teardown and rebuild of a 20b what kind of porting and etc, i have access to a dyno to tune it but i need to know what i need computer and igintion wise for it too since i can't find anything on what would be needed to do it. all i can find is sites here in the us that will install the whole package as ready to run. but i want to build it myself just looking for ideas and a little help.
