I need some information, I am planning an h22 swap into my 91 si, however I know traction will be a problem, so I need to find a transmission with LSD. However I see a huge lack of information on LSD h22 trannys. So whats the down low on it? Which years / makes have LSD? Whats the ID code on the LSD ones and where is it located at? thanks in advance guys!
