Hey guys! I wanna know how can I tell if a trans is from a JDM 90-91 integra XSi or a USDM 90-93 integra LS? I mean they both say S1 but how can I tell or test which is which besides installing it in the car and testing out the gear ratios on the road? The motor it came off is a B16A but trans can always be swap out so I just want to make sure because the gearings are alot different and I want to run a XSi trans! Thanks in Advance!
