ok, so i wanted to know how hard it will be for me to put a S5 motor in my rx7.

what do i need? what is the best way to do it? and how much do you think it will cost all together?



this guy that i am good friends with is going to help me put it in for cheep....

im planning on doing a similar swap with my 1980 fb at the end of the year. let me know how you get on and any problems you come across. sorry i cant be of much help. im a complete noob when it comes to mechanics and rotaries for that matter =/

yeah i am too....its going to be a while before i can get it done cause i work at mcdonalds and i get paid 6.55 an hour.

yeah i work at a local supermarket and the pay there is crap, hence why im not going to be doing the swap until the end of the year =/ ideally id have enough money to do a 20b swap. one can dream =(

yes very true....but it might happen one day. you never know what tomorrow will bring

Is it going to stay EFI or carbed?If you decide to go carbed then the swap is fairly easy.Just get the front crossmember, Front cover,oil pan and mounts from the 84-85 GSL-SE model to drop it in.They you will need to swap a dizzy on it as well.If you stay with the EFI setup then you will need to wire up the ECU.

im going to stay EFI.

whats a dizzy?

The Dizzy is the distributor. But I thought those were interchangeable? Also, I read in another forum that "the OMP on the SE front cover is run off a rod, while the S5 is electronic and will not bolt up to the SE cover", which makes that front cover swap problematic.



If I'm right, the only reason we have to change the front cover is for the motor mounts. It seems like there could be some kind of adapter...



I'm planning a similar swap, an S5 into an '85 GLS-SE. Seems like it would be just drop-in, except for the motor mount issues. I wish you luck!

lots of time and money
