hey guys hows it going well i have a 90 da with a b20vtec and i had a stock ls trans from the DA and picked up a ys1 from someone along the line but he told me it was an ls trans. now i have done a bunch of research and i cannot find a definite answer but i need to order my parts asap, so heres what ive got. its a ys1 on the label, when i got it it had an electronic speed sensor mounted in it so that kinda tells me someone had to have wanted it in a newer car. its a 24 tooth spline but the diameter is larger than the one off my previous LS trans, being an s1. so with that being said, can anyone tell me if its an ls ys1 or a b16/gsr ys1, and/or year so i know what to order. both 24 spline but the ys1 has larger spline diameter if that determines anything could use a lil help.
The guy you bought it from could and did tell you and it will be easy to confirm once it is in the car.
You order a clutch for a 1992 or 1993 Acura Integra RS, LS, LS Special, GS, GS with Leather, or GS-R
Well the guy hasn’t answered since I met him and im hoping othing is wrong with the gears I may pull the case to double check but your saying the 92 93 is the larger spline and it doesn’t matter obviously the motor but just the spline size?
Yes, the spline/input shaft size is the difference… 92-01LS can physically use the same clutch, 89-91 use a smaller spline/shaft size.
Well that works that’s all I needed to know cuz I wasn’t sure exactly before if I had the smaller or larger spline until I had my trans out but thanks for a solid answer cuz I always get mixed answers
