i have a b18a1 and need to know what transmission would be good to replace the stock one with.

Will the one from the Type-R (C5) bolt up? I don't know the numbers but that one has a LSD diff. too. Should be the closest ratios too.

 

im not sure if it will bolt up or not, does anyone know exaclty? but the LSD would be nice.

 

I'd go with a B16A tranny. The shorter gear ratios will give you better acceleration. However, if you drive on the freeway a lot, you'll find that cruising at ~70 mph will put your engine up close to 4,500 rpm. This isn't a bad thing, but some people get scared...

 

Or annoyed by the gas mileage/ noise while cruising. My tranny is at like 3-3.5 at 70 and the engine makes enough noise.
Who's car is that in your avatar?

 

so running at about 4.5 to 5 grand wouldn't hurt it?

 

youll want either another tranny form an LS, because of the gas mileage and lower cost of the tranny itself, or an early SIR1 b16a tranny with an LSD. more expensive, but the lsd is very nice to have.
