B series are all compatable, but can you swap 4th and 5th gears only? I need longer gears for crusing/economical driving. Compared to revving at 4 grand going 70mph. I'd imagine this is a common though or project. I would use the search, but I guess its down. If anyone has some insight or advice on this I'd really appreciate it. I'm looking to get part numbers, prices, and what I'd need as far as the two gears (from the mainshaft, and the countershaft). Thanks!

 

Yeah its possible. People do it all the time.

If it were my car, I would only switch 5th though.

 

Yeah, I'm just curious though. Can someone possibly list me some part numbers?

 

Get a GS-R Tranny, best of both worlds.

 

No, I want to buy the actual gears from Acura. If I can get them brand new then thats what I want. Do I need the synchros as well? I really dont know all what I need here...

 

x2

 

i like the short gears. revving at 4k doing 70 isnt too big of i deal. i did it and got 32mog with my b16... and that was mixing city and highway. keep the B16 gears IMO

 

I'd keep the 4th gear especially if you are still mated to a B16. The 5th gear I have been contemplating to change for a long time, but will probably do that when I install a LSD and my turbo kit hehehe.

This is probably best for the transmission forum to verify. I'm sure you would have to buy both gears for the main and countershaft. I doubt you need to buy new synchros. Call up Acura Carland in Duluth, GA or Son's Acura Parts in Morrow, GA. They have great discounts on Acura parts and I believe they know quite a bit of tech related stuff as well.

 

ok i have a b16 swap in my da with the ys1 tranny.... i put the ls 5th gear in my transmission and i gained alot of mpg from it... im getting about 38 mpg mixing between city and highway...the thing is 5th gear isn't powerful for climbing hills and what not but i like cruising at 2500k in 5th going 60 its deff niceeeee :-P

 

sounds comfortable. you need some boost for those hills though

 

haha nah im more of an n/a guy but i live in wv so the hills get quite big lol but its ok i need to slam the car but no money ahhaa
