Just because of the torque numbers and the fact they they aren't really sought after like the k series are. plus, you don't really see J swaps all the time, and you can find them everywhere for super cheap.

very much transversely mounted in the odyssey but other than starter position I can't really see a serious issue with changing it to a linearly mounted set up. the 3 engine mounts can hold the torque in the transverse set up so I can't see why they wouldn't work otherwise. Also that BMW swap sounds sick, only issues I would have wanting that is that now you're paying BMW prices for engine components and you have prissy German engineering under the hood.

I'm hoping that the small form factor of Honda engines specifically can make up for the lack of space. Since it seems like no one else has even thought of this swap I will probably have to do most if not all of the leg work when it come down to it. I heard one time of mock engines made of foam to help with planning and fitting but i havent been able to find one, i feel like that would be a huge help here lol

Most of the reasons boil down to efficiency and reliability. While I don't doubt the reliability of the 4.0L its not the good ol' days where there was 40 jeeps and AMC's at every junk yard, where as now Honda J motors are closer to 50 at every junk yard and no one touches them. Plus the reliability of modern Japanese engines is unparalleled in my opinion. All this is not to mention the fact that those v6's can push a 4000lb mini van to get 11L/100km combined, so I figure the same motor can push the 3300lb Comanche to at the very least the same mileage. All with no aftermarket engine parts.

Thank you for the tips and things to look for, i didnt even think about the exhaust width on a v6 platform and how it would fit between the wheel wells.

Thinking about swapping my 89 Comanche to a J32 or J35 out of a Honda odyssey for a multitude of reasons. I was wondering if anyone has done this specific swap before, or knows someone that did it. What would need to be done? I'm assuming a new subframe as the sump would end up being forward as the stock location for the starter motor is under the oil pan. Obviously any kind of engine control and wiring would need to be completely redone. I've been looking for a transfer plate pattern and haven't been able to find one as of now. most likely a custom throw out bearing would need to be made I would imagine. Not sure how accurate any/all of this is so any input, links, or advice is greatly appreciated.
