Can you weld the 4.1 limited slip (clutch type) in the naturally aspirated '86-'88 cars?
Mine is acting like it's an open differential at the moment, or I believe it is. Both tires spin forward when it's on jacks but only one wants to spin under load as far as I can tell. Will upload a video later.

My goal with the car is to learn how to drift, so I'm not opposed to getting an open diff and welding it to swap in if I can do so without changing transmission and driveshaft.

Wanting to know what my options are here. (Never rebuilt a differential before as well, so tips would be helpful if that's my only option)

 

It is a "limited slip". If you do have worn plates then I would just rebuild the LSD. When it's running as it should it rocks man. I doubt you'll like the feel of a welded diff... unless you're drifting. Driving it daily will get on your nerves.

You do have an LSD and they're hard to find. I wouldn't ruin it by welding it.

 

Good to know, I'll look for a thread on how to do the rebuild unless you know of some good sources of info for that. I do plan on drifting the car, it isn't really my daily. Just currently my daily for the next week while my MR2 is getting paint. Uploading video now.

 

 

recommend rebuilding with the more mazdatrix clutch discs for more grab if youre gonna drift. imho better than a welded. buddys grabs about 80% its perfect
