I want to change the factory 5 Speedon my 98 EX to an H22/23 manual trans with lower gear ratios. I'd like to get as much info as to the necessary parts (Axles, Clutch etc., even ECU if necessary) and Yr./Model of Prelude is best to use. I was told that the 96 Si H23/5Speed would work without any mods though claims are that any 92-96 Prelude 5 speeds will do the job. I just want to confirm before I purchase one for my swap. Si trannies are hard to come by. I searched here and honda-tech for info. but most people are changing them on 5th Gen. (OBD1) Accords or going from automatic to stick on 6th Gen. Your help and knowledge is greatly appreciated, thanks ahead!

 

Swap yours out, surface the flywheel or change the clutch while your at it (if it needs replaced) and swap the H23 one in. That's it. Make sure you bleed the line.
