hi. i'm at the stage to buy a gearbox for my race car and would be very greatfull of any feedback on the 3 gearboxes,
i know the ratios are generally the same with exception to the later s80 with 4.7 fd. i'll be replacing the diff with a race one and also 4th gear to bring it very close to 3rd gear as these will be the only 2 gears used during the race, (dirt 1/4 mile oval)
but how do the other parts compare? i've read somewhere the s80 has dual synchro's?

many thanks Adam

 

All '94 - '01 Integra transmissions are stamped S80, LS, RS, GS, GS-R, ITR. They're all S80. S4C is always a B16 trans though, and IIRC so is the Y21.
