What is need to swap a 3rd gen motor to a 2ndgen? Im thinking about doing this to my 87 Rx7 TII. How much would it cost for all the parts?

 

You'll need a complete 3rd gen motor, but you don't have to use the turbos. You'll need to make custom motor mounts. If you don't want to try to get the 3rd gen ECU to run the motor you can just use a standalone ECU. I helped a friend of mine with a project like that, and it wasn't too hard.

 

K2rd sells motor mounts for them but im too lazy to find the link.:o

 

The link for K2RD is http://www.k2rd.com . Their mounts are for the Cosmo 13B and 20B. I don't know if they'll work with the 13B REW. I remember Ted saying they wouldn't.
