im very interseted in this project also.. i just happen to have 2 250sx engines on my bench and basket case frame and my friend has a 350d engine that needs work just laying around. i am also very familiar with trx300's (i have 4 of them) and old trx350's. id like to make more power for bigger mud tires. one of my 250sx has trx300 rear diff and axle installed already. i couldnt find a replacement for the sx.

If you're going for mud, 100% 350D will give lower gearing. The primary gear set are high geared, but the output goes through an extra gear reduction gear set vs the other engines. I have to run everything the highest geared I can to get even close to sx/350x gearing, so going low geared should be really easy with gear set swap, rear diff swap (250es for example is lower geared than 250sx), etc. Of what I've read the 250sx frame mounts won't line up to the 350D engine, so if you don't want to build your own motor mounts, throw the TRX300 engine in with the output shaft swapped out, if you don't mind the extra fab work, then throw the 350d in. The trx350 vs trx350d has ac vs dc CDI, so for my case I'd be going AC so I can delete battery, starter, etc for the more "sport" focus, but for utility/mud keeping battery and DC CDI might be the better route. If I remember right the stators can be swapped if you kept the rest of the system matched up right, I think both ran batteries, just the AC stator has an exciter coil that powers the CDI directly while the DC one doesn't.
Any mod that works on the 350x top end should work just fine on the trx350d, so 400ex/450r carb, headers, etc. 100% you'll want to make sure compression release is working correctly for kick start, the kick starter is really short on the 350d's vs the 350x (maybe just swap out?).
Anyway, good luck on the project, some day I'll get this project moving along lol. Really need a garage to work in, would make life so much easier.
