Am I asking for alot of headaches attempting the install of a 1993 13b TT motor/trans into a 1987 TII ?? Will it 'slip right in', mount for mount ?? TIA !!

Yes, No.

You will need to fab your own mounts, and either rewire the car using the 93 harness, or go standalone EMS.

i can't see any point in trying to use the FD trans as opposed to a T2 trans either

there's info on this swap, mazdaspeed7 is doing it. i believe its in the rotary engine forum, might try searching tho as im not positive what forum its in.

unless you have one sitting around, pass this project up, its not a drop right in thing

Why does everyone say that? I dont think its any worse really than a RE swap.



Lets hear some specific reasons why not to use an REW? Sure, the stock twins suck ass, but the block itself has more bracing in critical areas than the RE, 13BT, etc. The rotors are a bit thinner on the face, and more prone to denting under detonation, but detonation often requires a rebuild anyways.



You have to rewire or use a standalone with any swap. Whats the big deal here?



Im selling the mounts if youre not able to make your own, so there goes that argument if you cant make your own.



The TII trans bolts right up using TII clutch stuff, the counterweight is the same betwen s5 and s6(REW), so again this is no more complicated than an RE swap.



The water pump inlet/outlet are in shitty places, but you could just use an FC pump(which most people do with RE swaps anyways), or cut and reweld the lower tube of the water pump and use flexible coolant lines, or just use a 3rd gen radiator. Again, there are options that arent any worse than the typical RE swap.



And a 3rd gen downpipe comes VERY close to the fc location, so not much work there. A muffler shop would have no problem tying a 3rd gen downpipe into the rest of an fc exhaust.



Heres the link to my swap. Im doing a lot of other things not necessary for the swap, like the radiator, oil coolers, and a lot of things yet to be seen. The majority of the swap is mounts, wiring, and plumbing, but thats typical of ANY swap. Personally, i think the engine fits very nicely, and I dont see why its so uncommon and so hated on.

its not that it cant be done, its just not as simple as dropping it in thats all, he asked if it would slip right in mount for mount

That is true, but any swap short of a n/a-->TII swap wont bolt up using stock components. But as far as swaps in general go, the REW is no more complicated than any other swap, and has come distinct advantages as far as im concerned.

see the one thing i dont like is everyone says the fd's rear plate is so much stronger. thats cause the mounts are there, it has to support the whole engine, of course itll be stronger, but all that extra strength goes into holding the engine up.
