I have a B16A engine and S1 transmission swaped into my 90 CRX.
I race the car on the track (not drag strip) and the current S1 transmission is having what I assume are syncro issues getting into 3rd gear. It won't shift easily into 3rd when the revs are high.
I have a L3 transmission from a CRX SI car/engine.
I know the ratios are wider in the L3 transmission, but are they wider enough to cause a negative effect in my racing of the car?
Additionally will the L3 transmission fit on the B16A engine?
If so what clutch/flywheel specs do I need, spline number / flywheel diameter.
Or should I just have the S1 transmission rebuilt, if so what should that cost?
 
Ok, I wasn't sure if you could mix and match the engines/transmissions.
Thanks for the reply.
Do you have any idea what it would cost to have the S1 transmission rebuilt?
 
if you race, i would consider getting the y1 tranny, which i believe has lsd.
 
the L3 is a D-series transmission which won't work with the B-series engine

There are adapter kits- they really are just plates with both bolt patterns on them and a disc/plate combo to cover the mismatch between the engine and transmission. Search for them. There are kits to mate B series and F/H series engines onto D series transmissions.
 
i never understood why anyone would want a d-series transmission from all my experiences they are weak and worthless... i understand to maybe make a swap easier considering the h22 trans is cable shifted but screw the d trans the only reason i have a d engine/trans still is i cannot afford a b16 swap right now.

If you're installing an H22 into a Civic or Integra, you have to cut into the shifter tunnel to make the H22 transmission fit, so that's part of the reason that kits like this exist, so that you can use a transmission that's bolt-in...
 
D transmissions are REALLY cheap to build up- for the cost of a B series transmission, you could have a Quaife style LSD and almost perfect gear ratios. If I was going to build another Civic, I would go with a custom D transmission behind a turbo F block. That's just me though. :)
 
i got a ys1 with my b16a1 and that works great for me...
