i need help with a cosmo swap
 

yes i have an 89 rx7 and i just bought the cosmo 13b-re twin turbo motor and what i need help with is what motor mounts do i us. also for bolting up the tranny and the starter is different how do i do that

I think wat u have to do is sell me the Cosmo 3 Rotor, its much easier after that.

1st old post I'm sure he has figured it out by now LOL. Second the 13b RE is the twin turbo two rotor option for the Cosmo, the 20b was the 3 rotor choice. A 13b RE is the early version of the 13b REW offered in the FD3S. These motors are similar except the 13b RE had larger intake ports from the factory & I think it used smaller turbos.
