so I have an auto teg and im gonna do a manual swap and was thinking I would love the b16s shorter gears for better acceleration, but I do get on the interstate to go to work for about 40 miles and this is my dd. my question is will I be able to to comfortably run 70-75? if somone knows the exact rpm that would be very helpful. I know the gsr ratios are in between the b16 and ls but would the gains be worth the extra money over the ls?

 

you will hate your life. put a gsr 5th gear in that b16 trans. that will keep you around 3500-4000 rpm in the 70's for mph

 

B16 trans is super short for a LS street car. Idk how much you'd like it...and since the B18B isn't quite as high RPM friendly as a VTEC B series....your highway MPG may not be all that great.

A GSR trans is great for the LS though.

 

i hated a b16 transmission on my ls. gsr would be a lot better.
