hey fellas, i've just swaped over a gear box, the gear box i was using is a 1990 CRX B16A cable clutch gear box, and the one i swapped over to is a 1991 Integra B18 Non Vetec cable clutch gear box.
Is there a gear ratio difference or final drive difference between the two box's. 60km/h in fourth seems about the same, but 5th gear at 100km/h seem very different?

Im pretty sure the B18 has longer ratios and has a 4.2FD?

they are completly different gear ratios. The b18a/b are longer by far. ie in 5th gear at a 100Km i sit at 3k and in the b16 gear box it sits at around 3600RPM

Indeed, B16a gearbox has close gear ratios to keep the revs high between shifts.... I bet your revs drop below VTEC with the 1st to 2nd shift now?

it is definatly different, i havn't been reving the car to much yet cus i have just put a 1.5way Cusco LSD in which i am trying to run in a little before my next race on the 19th. I have rev limiter set at 8500, i'll give it a squirt and have a look

thats about spot on for 5th between the two box's, 4th at 80 km/h is sitting around 3250 for memery in the b18 one

yes very different
with my S1 i can do about 95 in 2nd
with my YS1 i can do about 110-115 in 2nd and harder to shift back into VTEC
cant wait to swap it back !
