Hello guys,

Been reading a lot of the threads on swapping an Auto to 5 speed. I ended up buying a 1988 Rx7 SE N/A for 500 bux. Body is in excellent shape, car runs fairly well. Makes a good 'beater' for me =). I also have a 86 T2 parts car essentially w/a blown t2 motor and full t2 drivetrain.

Now the SE is auto and the T2 is 5speed. So I put 2 and 2 together and I want to do the swap since I essentially have everything available to me for 'free'.

Now I generally got what needs to be done but need some items that need to be cleared as some posts raised some questions for me:


1) Can I use a T2 tranny on an NA block. Most of the threads I read mentioned that it is possible but you have to use a T2 clutch, T2 Flywheel, T2 master Cylinder, T2 Slave Cylinder, T2 Starter (??). Is there anything else I would need?

2) Swapping the 5spd Clutch and brake pedal. Most of the threads I read mention you take both out and install them into the auto car (removing the Auto brake pedal). Now can I just remove the Entired Metal bracket that sits under the dash and bolts into the firewall? Or Do I have to remove each pedal by iteself and essentially disassemble it and install it in the auto car?

3) Differential: Swapping the 5spd Diff into the Auto? Can I just swap diffs? or gotta swap entire subframes?

4) Driveshaft: can I use the 5spd T2 shaft? I'm assuming so since the diff and tranny are essentially T2s.


Thanks again for any help that you guys provide =).

If the body's are ok, i'd say just swap the engine into the TII, since it's generally easier to do and a bit more reliable this way (instead of custom mounts, etc). However, if you do decide to swap the tII driveline over to the auto, you basically just swap the flywheel and bolt everything up to the auto car, (ALL of the TII parts should be used, flywheel/clutch, all hydraulics (master & slave), driveshaft, and starter though the auto & tII starter are interchangable). You'll want to swap in the tII diff, since the tII driveshaft won't bolt up properly to the n/a rear. And yes, the brake pedal & clutch pedal come out as one assembly, basically pull the steering column and glance under the dash and you'll see pretty easily what's required, you'll the whole brake pedal assembly, and then you basically just bolt the clutch/brake pedal back into it's spot, bolt on the hydraulics and then you're damn near done!

Alright Seems simple enough (though im sure there will be issues when I get down there

The body on the T2 is terrible, but the Auto is simply beautiful.

The issue with the pedals and using the entire bracket was sorta confusing but makes sense now.

Thanks =)

heres the pic from my pedal conversion the clutch and brake ride on the same shaft.as with the auto the brake is the only pedal to ride on its own shaft.two hardest thing i witnessed was fabing tranny mounts and looking up the wires to make the rear lights work.

I'd take the SE engine and put it into the TII body. Seems easier to me with more options for future plans i.e. putting the turbo back into it after you rebuild it. Make the base model SE your parts car. The Trubo has more potential. This will save you from posting "Want to make my N/A a turbo, what do I change" thread as well.

I was told the only difference in Auto's and 5spd was the flywheel config. An Auto has a counter balancer that fits into the rear main oil seal and the flywheel bolts to the counter balancer with 6 12mm bolts. If you want a lightened flywheel for performance you'll need to hang on that Counter Balancer.

Hmm, So did you swap the entire 'metal' bracket that the pedals mount into or remove both pedals from the manual car and swap them onto the Auto Car. Is the Bracket welded on? If its bolted wouldn't that be easier?

As far as swapping my na engine into the T2 body, well the T2 car is in terrible shape. Interior is torn up, exterior has dents and is primered only. The NA Body is clean. I need basically a fairly reliable ~150-160rwhp car that acts as a secondary car for when my 300zx TT is down for mods/repairs. I already have my 'speed and track' car.

Thanks again for all your responses.

well there is a hole cut into the chassis of the car auto or 5-sp.the brake pedal bolt on the auto runs through a shorter spacer.take the bolt out on the 5-sp and the two spacers theres one spacer for the brake pedal then theres another for the clutch pedal to run through.also you will notice the bolt from the 5-sp is longer because not only does it run through the brake but goes past the brake pedal and runs throught the clutch pedal.be sure you get all springs as well and little hardware.if you look closely in my pic the first one is of the clutch assy, the second photo is of the brake.you can see the spacer the bolt runs through.
