I have just transpanted a 1980 motor into my 1985 rx7. I have it running however i have issues with the electronis. I due not want to use the electronics off of the 85. I may need to put vehicle back with emissions in the future. Any suggestions choke oil gauge charging system etc. I installed header and removed rats nest from the 80 motor

 

you cant put the 1985 emissions on a 1980 motor, the passages are different, and it doesnt work.
