So does my bro. That's why I'm asking. I think it would be really cool to rotarize it.
The 13B is the same length as the stock engine. I'm must worried about the intake/exhaust getting in the way of the half-shaft/CV joint. On the Isuzu engine, the exhaust comes out of the plug side and wraps under the oil pan.

It's one of those projects that I'd like to do... someday. The Imark's carb has been rebuilt and is quite down on power. This car is NOT fun to drive anymore. My bro wanted to install a turbo engine, but I suggested a rotary. We'll decide on what it'll get sometime next month. It's my bro's car so all I can do is suggest stuff. I'm still rooting for the rotary

Thanks peejay. I didn't know anything about those turbo models, other than they were a factory option in the Imark.
I drove it a bit today. It's not that bad of a car, just gutless with a capital G! Hmm, I wonder how much power the transaxle could handle?
Here is an interesting page about installing a V6 into an X1/9.
http://www.angelfire.com/biz2/genera...ts/fiatv6.html
This page says the X's transaxle can handle 150 HP smoothly (no burnouts hehe). Hey, that's like the stock diff of my MG Midget according to the previous owner who broke a couple with his streetported 12A (with less than 150HP, probably)
I know that X trannies are not very strong, and two Xs that I'm familier with both had grinding synchros and then died due to a poorly designed internal part that ends up developing a hairline fracture along its thin edge.
Knowing the cause and fix for X trannies has sort of prepped me for the Isuzu tranny which has taken similar abuse and does not grind at all. To save money, I wonder if Isuzu used the same 5 speed in their turbo and NA cars? Maybe it can handle more than 150 HP RMS (to use a speaker term, ha!). So far, it handles little burnouts just fine. It even handled being used to make a smoke show in a residential neighborhood (back when it had more power) Not much smoke, but nothing broke hehe!
This seems like the ideal tranny for a rotary in this car. It already fits the car perfectly, it shifts smoothly and always goes into gear (even 1st when rolling, which is hard on my SA tranny), never grinds, seems stronger than the X tranny which claims to handle up to 150HP, and uses a clutch cable instead of master/slave cylinders (not sure if this is a good thing).
By the way, KEP didn't have any adapters for a transverse mounted rotary, and Mazdatrix thought it was a dumb idea. Looks like I'll have to fab up some sort of adapter.

I'm at a friend's house right now so I cannot get you the link at the moment, but I did find a truly crazy setup - some wack-job (I mean that in the kindest sense of engineering insanity/genius) managed to mate a 13B to a Mazda transverse FWD transaxle. And stuffed it in a 323 Wagon. Peripheral port engine, as I recall, and it only runs 14's. (Due to no traction, no doubt)
I want to know how he got the engine to clear the long axleshaft. I have a feeling he rotated the engine - rotating "plugs up" makes the most sense but without seeing the setup (pics were not allowed!) I do not know for sure how he did it.

As far as I know, nobody has ever done a fwd (transverse mount) rotary. I've been on the lookout for this kind of info for a long time and I've never seen any. No pics? I'd really love to see some pics of that 323.
I drove that Isuzu again yesterday. It's a great little car despite the sad engine. I've got to put a rotary in it some day. I don't think I'll need to go plugs-up, but some rotation will be needed.

The reason you haven't seen many (if any) FWD rotaries is it is not as simple as doing a engine-tranny adaptor with a rotary engine. This is b/c on 99% of FWD transaxles, the axle which crosses behind the engien to the other wheel, crosses directly inline with the rear-facing exhaust ports on the rotary.
The only way I have figured to get around this would be to rotate the transmissison and custom moutn it on an angle or something. Or do that same with the engine.
Either way you will have to re-do your oil systems on both as well.

I'd most likely rotate the engine and redo the oil pickup tube. Probably the entire oil pan too. If going NA (not that I have much choice, heh) I'd need to make sure the carb still sits level and rotate it 90º so it still feels the same G forces as it did on the longitudinal front engine-rear drive of stock. Like a cork screw intake manifold adapter. Sterling might be interested at this point Anyaway, the oil metering pump would need a new interestingly curved rod, and the exhaust would neen some wrap or heat shields because that part of the engine bay was not designed to handle that much heat. The CV shaft would need to lose its harmonic reducing rubber thing located in the middle of the shaft. I hope it'll be ok without it. Maybe I could just slide it up or down the shaft or add another homemade one? Racing beat coats their tension bolts with silicone to reduce harmonics...
I hope the 5 speed in this car has the same internals as the turbo model. Now I'm off to check out Isuzu websites for more info. Ever seen a souped up Imark? It looks a little out of place, lol! I'll see if I can find those pics my bro found a long time ago.

about 2 years back i saw and rode in a Mazda Rustler pick up (323 pick up) in Johannesburg ,South Africa.
The guy had a 13b bridge port mated to a Mazda 626 2l 16v gearbox .What was done for the conversion i don't know ,but what i noticed was that the diff section of the gearbox was just below the sump.Ive been trying to contact him again because i wanted to put a 13bt in a VW Golf 2.If i get any info i will post.
