I have 2 fd's. I got into an accident w/ 1 and I want to take the engine & trany out and put it in the other one, but the other is an automatic, is this possible to do?

Yes it is, just swap everything related to the manual, clutch master cylinder, pedals, etc.

You can do it, however you will need to take a close look at the Tranny TUnnel. They are different in the mounting bosses area where the tranny mount attaches to the car.
The Manual has a fairly symmetrical mounting arrangement, with two bosses similar in mounting and size that the Manual tranny mount attaches to.
The Automatic has the bosses not only in a different location, but they are two different sizes, therefore.. you will need to fabricate a tranny mount.
There MAY be someone who makes one, but I do not know of them, the vast resources out here in the forum may know of someone who does.
Also on I believe the Late 2nd gens.. the Drive shaft is different between the Auto and manual. BUT DONT QUOTE ME.. it is simple to check. Just pull it and look.
I have a 88GXL that was a auto that I put a manual in, and the driveshaft worked fine from the manual.

Notes... It is a pain to do the pedal assy.. you will have scraped nuckles.. also the mount for the tranny is a pain... And WORST OF ALL..... the Auto has a 3:90 rear in it... and the car is gonna be SLOW... but will get better mileage.

dude that rear end is good. On mine It had a slower pick up but a mean top end. plus it gave enought time for my turbo to spool.

And WORST OF ALL..... the Auto has a 3:90 rear

isn't it possible to change it though?

SPiN Racing - are you talking about 2nd or 3rd gen rx7's?

Spin, there's no need to "mount" the tranny of an FD. Both bellhousings bolt right to the motor.
