Tranny conversion
 

Ok guys give me some help here. I plan on restoring my 87 rx 7, but it is an automatic, just wondering how hard it will be to switch it to a manual, I have a lot of bodywork to do before I pull this off. If anyone can help and give me some advice, I would really appreciate it.

Not very hard depending on how much effort you want to put in. I replaced a tranny (manual for a manual) right after I got my car. All in all I'd say it was a 10 hour job. This is with very very little mechanical knowledge. Add about 2 hours onto that for automatic swap (for me at least).

what about mounting the clutch pedal, running lines, swapping out the rear diff?

:confused:

manual into a manual is a one or two hour job (or more); depending on annoying factors of how nice things are being that day. i wouldnt compare replacing a manual tranny to swapping auto, though.

i believe theres a write-up at www.rotaryresurrection.com for auto >> manual.

One of my friends who likes working on cars did that swap. He said he would never do it again because it was so much trouble. ;)

BTW, the differential has the same flange as any other NA FC, so you can keep it as long as you don't mind the gear ratio. However, you will need a MT NA driveshaft because the AT NA driveshaft is too short to proplerly mate with the shorter MT transmission, and the AT driveshaft will not mate to the MT transmission.
