I am looking into putting a 13b rew in a 1st generation 1985 rx7 does anyone know of anyone or any websites that have any info on this The more input the better zoom zoom zoom

 

I replied to your e-mail already. You can see a 1st gen with an FD motor at http://www.rx7s.com .

 

I don't see any first gens there w/a 13b rew I plan on keeping it stock (motor that is) and use the ecu that came from the 13b

 

Look at Romeo's GSLSE.

 

Sweet first gen but Theres no info about how he swapped the 12a out for the 13b

 

The GSLSE came with a 13B. Your 12A has its mounts at the front, but the 13B REW has mounts on the rear housing. The usual way to overcome that is to make a cradle for the engine to mount to. Then you can weld/bolt the cradle to the frame.

 

Thanks do you have any more advice as in how much room will i have in the engine bay to play with

 

You'll have a good amount of space to work with, but I'm not 100% sure if the stock twin turbos will fit. You'll need to run an electric fan, unless you want to make your stock fan clutch work on the FD motor. Don't forget a front mount intercooler.

Front Engine Mount (13B into 12A RX-7 chassis)



This Front Engine Mount allows any 1974-85 13B engine to be installed into any 12A RX-7 chassis with a minimum of difficulty. (The stock Mazda front engine mount for a 1984-85 13B GSL-SE will not work because of differences in the front cross member.) When used with the 1984-85 GSL-SE 13B RX-7 oil pan, this mount greatly simplifies installation.

 

Or you can go to the wrecker and buy the GSL-SE crossmember and use the 12a front cover and mount.Mine I replace the crossmember seeing as the crossmember was only $75.Just beware the rusty bolts!Heres a page that might interest you.It's the Turbo II swap.But with a bigger turbo you run more power.12a-13bt Swap Page!He even put prices and wiring up on the page.
