Im rebuilding my FC after i blew a rotor and i was thinking about putting a motor out of a 93 rx7 into my FC how hard is this gonna be

 

very hard.. Mounting points are completely different the wiring is different... period the end not worth it.. theres a link at the top of the thread called FAQ gets into more details if not the search function works as this question has been asked many many times

you'll gain like 30-40hp for a LOT of work and money. unless parts a abundantly available to you. it's really not work the effort.

 

turbo2 swap would be much easier.

 

hmmm well thanks guys good to know my buddy just wrecked his fd and was gonna give me his motor and trans for free but if its gonna be a crazy swap ill just do a turbo 2 swap

 

Get the motor and trans and sell it. You could make money for your rebuild or turbo 2 swap

 

not again...
