gslse motor you are thinking of putting in?
i think the gslse has the front cover motor mounts
so it will just bolt in, you might have to put new holes
in the bracket that holds the motor mounts because
of the extra length of the 13b over the 12a.
I am in the process of putting a 13b into my rx2
along with a 5spd and supercharger

The twin dizzy tranny is 40mm shorter than '74 and later trannies. You'll need to have the driveshaft shortened.

you have to reverse the oil pan and modify the oil pick up tube since the oil sump is the rear.

I used a gslse oil pan and made a pickup.
the gslse oil pan was the only one i could find that would work, the rx4 and cosmo pan would have worked
if i didnt use the cosmo 5 spd which is longer.

You can also use a GSL-SE engine mount bracket - it has a shallower offset to allow the front of the engine to sit further forward. Of course, you can also oval out the 12A mount holes so that the whole bracket sits 20mm further forward in the car. An -SE wiring harness and fuel pump wouldn't be a bad idea either, of course.
