I've seen lot's of b18a/b with gsr tranny's but haven't seen much of b16's. Any reason why not?

Well post up if you do

 

From what I've read B16 trannys are geared for a high reving motor, which the b18b def. is not, and the high RPM in 5th is just not very economical for daily driving

 

What rpm's are b16 tranny's usually in at like 40-80mph?

Would it be bad on the motor also?

 

i was gonna ask the same Q? because i have a GSR and B16 but dont know what to put in with B18 ls engine....

 

my friend has had both and currently has the b16 on right now. to me, b16 stays higher in the rpm's when cruising, but the car pulls good w/ the b16 tranny being nice and short.

 

i've seen stock b18b with cams, b16 trans, & sprayin 50 shot in the high 13's in qtr
sounds easy & fast

With a B16A transmission, you are running at a little under 3000RPM at 50MPH. And at 80KPH, you are running at around 4500RPM. So you can see that if you run a B16A transmission on an LS, you are not going to have a happy camper on the freeway. The LS motor was simply not made to run at close to 5000RPM all day long on the freeway. So unless the car is not going to be a freeway cruiser, I would NOT use a B16A transmission on an LS.
