OK,I'm about to buy a 89 S13,5 speed SOHC with a open Diff and I had a question and I knew just the forum to ask it on! Without buying anything else RIGHT NOW (with the exception of a tune up) can I buy a lsd and drift with that? I plan on saving the money for a 1.5 later down the road but i'd like to get some seat time in. I can get decent/badish tires to drift with. No disrespect to anyone but PLEASE DON'T SUGGEST A WELDED DIFFERENTIAL! I do not want to weld anything on my car unless ABSOLUTELY NECESSARY! Also can someone please explain what the difference between a mechanical and clutch type LSD are? I greatly appreciate all the help I'm sure i'll get from this thread.
