There is more than one version of the YS1. There is a rare, highly-desireable, short-geared version from the '92-93 GSR, and then there is a much more common long-geared version from a '92-93 LS. These are for the USDM YS1; I'm not sure about the JDM YS1 (if such a thing exists). If you have the long-geared version, you really got bent over big time. If you have the short-geared version, you made out pretty well as long as all of the internals are good.

The trans should bolt straight up to your B-series engine with no problem. Use a '92-93 Integra RS/LS/GS clutch.

Hmm, okay thanks for the correction. I was under the impression that all of the B16A-powered JDM DA Integras had either an S1 or a J1. Looks like I was mistaken.

The '90-91 LS trans is the A1, which has a 4.40:1 final drive as opposed to the 4.26:1 final drive in the newer YS1-LS.

I've heard mixed stories about this. Some say that this is true. Others say that both 1990-1991 and 1992-1993 have a 4.40 final drive. And yet others say that both have a 4.266 final drive. Given the notoriously inaccurate information on the web, it is impossible to say which is true without either consultig a factory Honda manual or counting gear teeth.
