NOLA85RX7

hey to all...I have a 1985 mazda RX-7...it came with a 12A rotary engine with a Nikki carberator on it...I recently took the stock 12A and transmission out...I have decided that I wanted to put a 13B Turbo engine with a matching transmission it it...and was goint to upgrade the intercooler and turbo and also was going to upgrade the fuel injection a little...I have no idea how but my Brother does so I am going to learn something from him....I am going to put a stage 2 clutch with an aluminum flywheel in... I am going to do other things to help peformance...but when it comes to the rear end..I am stumped...now with me having a 13B turbo in it can I put a rear end from a later model rx-7 in it and if not what rear end can I use?

Hi, I see no one responded to your quest. now I have similar requirement as you were. how did your project when on? I am also interested to know how you did the turbo tran to the first gen, did it fit direct with out any mod cuts to the body? Please reply if you have any helpfull hints on your own thread. Thx.

Rear wheel locked up cause the car was stored for years with 8500 miles on it. then the original owner drove with out fixing the rear wheel lock for about 100 miles like that. I bought the car and got this fixed, but noting the noise on freewheeling with the differential clunk. so the idea is to change to a better differential that will with stand future upgrades on the engine to turbo II. One point in mind is that I do not want to put any mod cuts to the body. keeping the body original I like to improve the performance and handling. Please help direct. I been searching but found some major enhancements and add on etc.
