4th and 5th in the 99 g20's are known to be super weak (also road proven by myself). They are way longer than is necessary. Shorter 4th and 5th should give me slightly better acceleration in the 70-100 mph range, which sounds like fun to me... For the record I am not actively seeking a transmission at the moment. Just trying to jump on good deals while they are available. At the time I posted this I had poor connection and didn't have time or patience to learn that 240sx's are RWD. Is it a slightly embarrassing post now? Sure. But I had the balls to ask what I needed to ask when I needed to ask it... And yeah, sounds like it's the 91-94 se-r trans that I want...
