Hey i got a question i have a 87 rx7 turboII and i was wondering my engine isn't doing that well and i was thinking about puting a 3rd gen rx7 engine twin turbo in it, what would have to be done to the car to put the 13b tt engine in it?? Also to have the car run strong?? thanks alot

 

generally it is not worth the effort and amount of work required to put in a 13b rew (3rd gen engine). the motor mounts are different and just a bunch of other stuff. Do a search if you want to know the details. With enough time and money anything will fit.
