Advice about Swap 13b into 83' S
I have a 1983 rx7 type S. I have about 141K on the orginal 12a and was thinking about swapping to a 13b. I was thinking about swapping one out of a 85 gsl se but I was wondering what would be needed. i plan on trying to get the motor from Atkins Rotary because they are local, but I was wondering what other parts would be needed to do the swap. Thanks.

throw a turbo 2 in it..if your going to do any kind of swap, that would be it..here you go..a nice write up just for you..
Turbo 2 Swap Into First Gen
GSL-SE parts:
Oil pan
Oil pan gasket
Oil pickup tube
GSL-SE rear end differential
Custom driveshaft
12A or GSL-SE parts:
front cover
front cover gasket
front crossmember
transmission crossmember
Home depot:
3/4 Box steel (you only need 3 inches worth)
8mm x 1.25 x 45mm metric bolts and lock washers
On the engine:
Take off the TII oil pan, front cover and oil-pickup tube. Discard these elements, you won't need them. Drill and tap any spot on the first-gen front cover for the oil drain. Install the oil-pickup tube, front cover and oil pan with their respective gaskets.
On the tranny:
Remove every bit of the TII crossmember gear, including the soft rubber mounts and the large single bolt held on by two smaller bolts on the bottom of the tranny. The two smaller bolt holes are where your mount will be made.
Get your hands dirty, hold a piece of paper flat against the area surrounding the bolt holes and smudge the paper with your dirty hands. you should get an impression of the bolt holes as they are on the tranny. Use this impression to drill two holes in the 3/4 box steel. Cut the box steel into a section no longer than the width of the flat area on the bottom of the tranny. You now have a tranny mount.
Installation:
Join the engine and trans, and attach the front crossmember. Sit the motor in the car on the stock mounts. Lift and support the rear of the tranny into the tunnel, and notch the metal at the rear of the shifter hole in the tunnel to clear the rear of the tailshaft.
Drill two holes in the crossmember using the same template you used to drill the box steel mount. You'll have to drill the holes about 1/2" rearward of the stock mount holes on the crossmember. Use the 45mm long bolts to secure the crossmember, mount and tranny together.
That's all there is to it.

Most of it's good, but there are a couple errors, better methodology. To keep the stock MOP system, one must use the SE front cover. The turbo return line is best tapped on the land directly underneath the MOP on the front cover. The shifter housing and rod can be removed and and shortened 1". This will keep the shifter in the stock position. The oil pickup tube can be from either a 12A of 13B, as long as it comes from a 1st gen engine.
Then you need to deal with all of the fuel mods to feed the TII engine. This is where starting with an SE chassis has it's advantages.
