I recently bought a 91 3000GT VR4, and the first thing I want to do is convert it to RWD. Looking for the solution that will give me the absolute least power loss possible. I've thought about just welding the spider gears, so that if there's any mechanical issues I can reverse it by getting new spider gears instead of a whole new dif and potentially a whole new transmission, but I think I'd lose a lot of power. Anyone who has experience with this or resources please let me know! Thanks!
