6-Speed Transmission

[lagunabluek]

Does anyone know if there is any company that makes a 6-speed for a B-series motor. If not what type of trans do you recommend for an all-motor drag car?

How fast r you planning to run??? Stock B-series can handle more than you think!!! unless your trap speed pass 140mph.

If you want a 6 spd, get a K series.

Well, im building a B20/VTEC that is bored .60 over, 12.1:1 comp pistons, ported head w/ OS intake valves in a stripped CRX. i was thinking maybe somewhere in the 14's? Im not sure tho with this altitude! Im just trying to get tranny ideas

mmm please tell me this is stock sleeves!



btw the only 6spds you can find for fwd cars are in the $20k range; USED from what i've seen

Yes it is on stock sleeves. I was just curious if there was anything out there! Now what 5-speed should you use???

All-motor, go with a B16. Turbo'd, I'd suggest GSR. B16 has shorter gears which will definately help you with an N/A setup.

here are some pics as of now of the motor

Out of curiousity.....why'd you build an n/a motor? Why not just a stout turbo motor?

[lagunabluek]

That is a question I have been asked alot! Well I bought the B20 thinking that displacement was gonna be key for boost, well, then I was told that it was better to boost an LS, so I ran upon some 12:1 JE pistons for super cheap and decided to go all motor on this one. But now I figure that I am almost done with HS, and once I am done with my airframe and powerplant schooling, I figured that I would be moving down to lower elevations in the not too far future. But once this is done, I will start building an LS/VTEC strictly for turbo. Hope that answeres ur question!

Mugen or one of those JDM brands makes a 6-speed sequential for the B-series, but they're pretty hard to come by, and it'll run you $3-4k used. It's not worth it. Just pick up a Type-R or '99-'00 Civic Si tranny.

Those sleeves are going to crack.

I'd like a 6 speed for economy....my 5th puts it at 4000 rpm at 80 mph. :frown:

Because n/a is a completely different animal. They sound good and the powerband is even better. They have their benefits (and disadvantages) over forced induction.

[lagunabluek]

.06" over on stock b20 sleeves... wow; those'll crack the first run
