I'm looking for an engine tranny combo, pretty much set on the B18C GSR engine but I'm not too sure about what kind of gas mileage I'll be getting with the tranny, does anyone know where I can find a listing of the different B-series trannies and what RPM they're at in 5th going 60? Or even top speed and RPM. I have yet to find anything of the sort and decided to ask.
Thanks
Justin

 

If you are worried about gas mileage get an LS tranny or an LS 5th gear in a GSR or ITR tranny.

 

with a b18c1 that is stock with bolt ons, stock ecu and gsr tranny in a civic sedan i was able to do 27mpg daily driving and 32mpg on the highway.

 

The LS 5th gear sounds most like the best choice.
