ys1 is a gsr tranny. are u sure its a A1 tranny and not a S1. either way it really doesnt matter cause they both are almost identical gearing

Before you guys make up anymore bullshit, here. This is absolute fact, so pay attention.

1989-1991
USDM Integra RS/LS/GS- A1/S1
JDM Civic/CRX SiR- Y1
JDM Integra RSi/XSi- S1/J1

All these transmissions use a 25mm input shaft and require the use of a 1990-91 Integra clutch disk.

1992-2001

92-93 USDM Integra RS/LS/LS-S/GS- YS1
92-93 USDM Integra GSR- YS1
92-93 JDM Integra RSi/XSi -YS1

All JDM/USDM Hydrolic B-series Transmissions.

These all use a 26mm input shaft and require the use of a 1992-01 Civc/Integra Clutch Disk.

All pressure plates and flywheels are interchangable between all B-series engines and transmissions.

Gear ratios can be found here.
