Does anybody know if the J-spec. tranny on the B16 is geared lower that the USDM. The swap that I have in my car is at 4100 rpm at 60 mph in 5th. It does not have a factory LSD. Is there something wierd that I got my hands on? (not that I'm complaining...the low low gearing is great!)

 

The early J1 and S1 trannies are geared liek a type-r tranny.

 

Do you know if the Diff. is any stonger? Will it put up with slicks?

 

i have a b16 trans on my b18b..at 3000rpm im going around 50mph in 5th gear..

if you put on slicks..just got to watch out for your axles..
