I'm currently running a B18B1 in my 89 civic hatch. The tranny on it now tops at 110 mph at 7200rpm, this sucks. It's a cable tranny with no code that I can see,although it does have a LSD. I need a tranny thats more friendly when going over 60 mph, aka not at 4000 rpm.

I've done a little research and figured a YS1 is what I need. I have based this decision off of what kind of car it came from and that it's sold in america(parts reasons). I still do not actually know what the characteristics of this transmission are. Could someone inform me of the the top speed in all gears and the rpms at those speeds or maybe just point me to a chart. I was also wondering if it's possible or a good idea to take the LSD from my current tranny and put it in the new tranny.
