I have a 1993 Civic Ex Coupe with a 5-Spd Manual Trans. This car is completely stock. The p20 tranny's shaft ball bearings are grinding in all gears. I'm about ready to purchase an S20 5-Spd Tranny to swap with the P20, but can't find any specs about it on this site. Can I swap my P20 with S20? Is there any problem with the original p20 axle half shaft lengths, motor mounts, or mating surfaces? Any feedback is greatly appreciated. Thanks.
