Does anyone make this has it been done before

 

Never seen one, especially since the B-series motor rotates counterclockwise.

Wouldn't it make more sense to use the F20C?

 

why the eff' would you wanna do that?

 

5-6 Reverse gears.

just a thought I am almost finished with my built sleeved turbo b16 in my race civic but was thinking about building a prerrunner ranger also and using my b16 engine because it would f'n rip out at the dunes and b something other than everyones ls1 sandrail but I forgot about the reverse rotation thing I e-mailed a company today that sells a 5spd tranny for rwd b-series but I asume big$ for that so I thought s2000 would be much cheaper with an adapter but I guess that is not going to work

thanks for the repies that were helpful

 

G-force makes a transmission specifically for reverse rotation engines.....on the contrary you could get a reverse rotation rear end, or make the engine spin backwards.

 

cant you just use a K series with an adapter plate for the AP1 tranny?

i was told they will bolt right up but i think i remember seeing an adapter plate for the set up somewhere. a K24 with an s2k tranny would be nice

 

Or s2k with K tranny haha

 

Im already making an adapter plate.

i wasnt planning on selling them cause i didnt think anyone would be interested in buying one.....

i have a 2k2 s2k tranny and i will be working on the adapter plate later this week.

U just have to use a different differential or flip the differential around.....


HERE IS THE BOX [] Honda-tech lives in it..... U want to think []&lt;--- out of there.

let me know how it works show pics and i will buy one b to s2k

 

oh yeah and for those of you who ask WHY?

again... think out of the box....

the s2k tranny(depending on year) has very agressive gearing just like the type r transmission except theres a 6th gear so u can cruise on the freeway.... ontop of that its designed for a rwd chassis so that allows u to upgrade several small trucks and other types of cars with better gearing.....

now the B series engine is because its cheap..... atleast compared to the K and F series engines.....u can build a powerful LS vtec or cheap and the availability of more affordable parts is just overwhelming compared to the F and K series....

Probably the most important factor is that wiring for the B series is a hell of a lot easier to come by... older cars... higher availability....
And if u use an OBD1 engine...(which i recommend highly) then there will be a hell of a lot less wiring work needed to get everything working great.... in just about any rwd car... or modified fwd chassis.

 

to build a k may be a good strong powerful engine but why would anyone say build a k not a b when there are so many high power b's out there if your building an engine why not use the cheaper way when horsepower and reliability are availible with both setups

 

i don't think i'd run a b series on a k or f tranny as the tranny will be spinning in the wrong direction.... sure you can flip the diff/rear end but that doesn't solve the fact that the tranny will still be spinning backward. helical cut gears don't like to spin backwards reliably. i think the answer is a tranny with straight cut gears... that way it doesn't matter which way it spins. or you can just do what i did and get the whole s2k drivetrain and scrap the b idea.

well in reality the diff doesnt need to be flipped. cause it will be spinning the proper way when mounted to an s2k tranny....

the reason the s2k and k series engines spin clockwise is the way they are mounted in the car. If u mount the b series engine in a dc chassis it will spin counter clockwise.... but if u were to mount it the way a k series engine is mounted... that is with the intake manifold facing the front.... it will spin clock wise.....

same if u mount it to the s2k tranny longitude wise the way it should be.. it will spin clock wise too... and the s2k tranny will work as intended with the teeth traveling in the correct direction so no damage will occur.

 

And i am almost done with the plate... i just have to figure out a starter location... i havent taken the time to do the starter issue yet but so far so good... so im confident it wont take me long to put a place for the starter once i get started on it...

i am also working on a adapterplate to mount a b series engine to a k series tranny...

dont question my reasoning.... i have great reasons... those who see it my way need no explanation.

 

i'm confused here. how does changing the mounting orientation of an engine change the direction it rotates? a b spins ccw regardless of which way it is facing, and a f/k spin cw regardess of which way they are facing. the rotation is dictated by looking at the cam gear end of the engine, not one side of the car. if you mate a b to either a k or f tranny it will be spinning the tranny backwards unless you mount the tranny to the crank pulley end of the engine and i don't think that is reasonable option. does this make any sense?

 

yeah it makes sense im going to look into it further.

I still believe i am right but i am not one to shoot down other peoples words without investigating first.

 

yeah dude... no matter what way i try to see it the outcome is the same for me....

 

Just use an NSX motor, an adapter plate, and an AP1 tranny. That's what I did in my prelude.

 

i think you'll be disappointed with 6 reverse gears. i investigated this idea a few months ago posting on a variety of honda/non honda forums to see if any other oem made a rwd tranny that spins ccw... and i even wrote to turbo magazine asking about mating a b series to a rwd tranny and they said about the only option was to either have a custom tranny built, or to scrap the idea and go with an f20c complete drivetrain... (which i opted for). i did get a good suggestion from someone to spin the b series cw with some custom cams and a few other things... this has been done by a few people with success, but it seemed to be to expensive/complicated an option imo.

 

just buy an f20 swap and put a k24 crank in it with custom pistons and rods

 

Providing that the tranny will take being spun the oposite direction without issue, really it's *MUCH* easier to just flip a rear end upside down and possibly have a back cover fabricated to deal with oil filling issues etc. Kit car guys do similar things all the time using porsche transaxles in mid engined cars.

It's really not a difficult problem to solve. The fab isn't even that tough, its just a hundred million little packaging, wiring, bracing, putting it all together issues etc that will wear on you.

that is the problem though isn't it? helical cut gears only like to spin in one direction reliably... hence why i mentioned a straight cut gear tranny earlier.

actually, with the tsx (k24) crank and some h22 rods and pistons and some minor modifications to the rods and block, you end up with a f24... we can all thank gary castillo for figuring it out.

 

has anyone tried the gforce b rwd trans? if so how well did it work and what did you do to mount the b engine n/s?
