i guess this could be in the fabrication section, but i just have a question..is there an adapter plate/bellhousing that can be used to make a b series motor rwd? i've seen a few of them but theyre all using professional racing transmissions. if there is an adapter, what trans can be used? thanks alot.

 

Contact R and T autoworks in aberdeen North Carolina. We make oil pans for their RWD B series race car. They have perfected the art.

 

it would be hard cuz the motor sits the opposite way a RWD motor would

ive seen a few D's and K's into VW Bug's tho

 

G force makes a reverse rotation transmission called the GF-5R for the B series

 

You turn the motor 90 degrees. This isn't for a Honda.

What about an h22? Those rotate normally don't they?

 

i was actually working on mounting a b series to an s2k transmission... the problem is pretty much all rwd transmissions are for engines that rotate clockwise... which most engines do including all new honda engines and larger honda engines. b series h series and d series and pretty much all honda engines that are 5 cylinders or less rotate counter clock wise untill the s2k f20 series and k20 series came out

if u get custom made gears that are straight cut gears then the transmission can rotate either way freely.

currently debating attempting to make a gear box that changes the rotation of the b series engine or just getting a j32a2 for the s2k transmission i plan to use in my rwd teg conversion.

 

G-Force Transmissions, a leader in the design and development of driveline components for Professional Racing Teams introduces the Reverse Rotation GF-5R 5-Speed Transmission.

• Drag/Road Race Application
• Vertical Gate/H-Pattern Shifting
• Utilize Any Rear End Arrangement
• Utilize Honda Engine Technology

The reliable GF-5R 5-Speed Transmission, adapted for use with reverse rotation B and H-series engines allows anybody utilizing a rear drive combination to use Honda engine technology with a standard, no
hassle driveline. Currently G-Force Transmissions is the only company manufacturing a rear-drive transmission for these Honda engines.
G-Force offers a full line of driveline components for the Import/Sport
Compact racing enthusiasts.

 

you could buy a complete s2k drivetrain for less than one of those transmissions i'd imagine. just do that. that was the most sensible option for me. i would have loved to keep my b, but it is much easier/cheaper to do the complete s2k.

you also have to keep in mind, the transmission is only a small part of the equation... you will also need a rear diff to match the rotation, or flip one upside down... which will require more custom fabrication for the subframe.

 

yeah the rear parts are the easier parts though u don't have to get an s2k differential and its not recommended cause they tend to explode from high horsepower so something like a differential from a 300zx would be better.

that 5 speed transmission.. while easier cause it rotates the correct way for a b series... i think for the price u can take a different route and have even more power... like mounting a j32a2 to an s2k tranny is totally doable with an addapter plate.

the s2k tranny actually has very similar gear ratios to that of a integra type r transmission except for the fact that it also has a 6th gear for cruising... so if u have a daily driver u want to make fast like me... the s2k tranny is a good option especially if ur trying to keep the honda parts theme.

 

if you had a completely built motor and turbo along with a bunch of other things for a car I would give that transmission a thought. Ya an s2k swap would be easier, thats what I have for my car but I would have loved to have a gsr motor. the stock s2k trans in my car or yours weir is on borrowed time, that transmission would stand a chance to what I would do to it.

 

You could go the "transaxle route" and mount a Porsche 914 transmission in the back of the car with a torque tube running through the car with the driveshaft. The 914 transaxle can be easily flipped to turn the right way, and you get the benefit of better weight distribution from mounting the gearbox at the back (like a 944, Corvette and others).

And if the 914 unit won't handle the power you're planning on running, you could go with a G50 from a 911.

This method would make it a little easier to fit it all in the Civic/Integra engine bay without having too much of a tranny tunnel between the seats.

 

jaques... are you going to do that? haha, sounds like u have done some research.

 

Many years ago (probably 15 or more) I worked with my buddy building pretty much exactly what I describe above using a 1984 Prelude chassis, a 1993 Prelude 2.3 litre (H23), and a 914 transaxle. We were about 85% finished the build, and all the difficult fabrication was done. The customer got bored with the project, tried to sell it complete, but ended up parting it out in the end.

The chassis, which had been substantially modified (understandably) went to the wreckers for scrap.

As cool as that was to work on, this will be my next big fabrication project:

 

i just purchased the gforce reverse rotation tranny. i will be using a ford 9" rear end. the tranny comes with an adapter plate and bellhousing. i wanted to stay with the b-series because of the nhra lbs/ci rule for my specific class.

 

I'm assuming you're drag racing that, redboost10. Otherwise an entire b-series swap moved to the rear is ideal for road racing. Very low moment of inertia, and nearly 50/50 weight distribution.


Jaker, the picture of that "low cost" or whatever you want to call it....pure sex. I'd drive up to a guy in a super car and just shout "**** you". lol, then procede into a F&F highway street race.

 

It's called a Midlana. Basically a mid-engine Locost. The guy that's building it is using a turbo K20, and just had it dynoed yesterday: 409whp! Oh, and it weighs right around 1,400lbs.

 

yes it is for nhra so i will be drag racing it in superstock. i could have went with a s2000 longblock and not worry about the reverse rotation but with the larger displacement of the s2000 motor, i would have to add more weight than i would like to for a rwd 4cyl setup like this.

 

What about a drysump oil system, electric water pump, different starter, and backwards spinning cams?
Then spin the motor over the other direction

Probably still cheaper to go s2000 stuff, and less work.

 

i went with a peterson dry sump system with moroso oil pan, golden eagle electric water pump, still using stock honda starter, and cams are custom.

the reverse rotation gforce trans is the same price as a regular rotation cam so your not saving any money by doing some r&d with cam that spin the motor the other way...unless you wanted to put an automatic behind the b-series, but that just sounds boring to me.

i dont know if it would be cheaper to go with an s2000, because its a bit more to build an s2000 for high hp and like i stated, the trans are the same price.

 

yea, just buy the whole s2000. cheaper than a g-force transmission.

 

I don't think the s2k trans can handle 1k hp......

 

damn it jaques.

take me for a spin once its together. haha. ill have to come over and have a cup of coffee and check it out once u get started.

i guess i still need a ride in the wagon yet too... :D ill trade u for a rip in my drag car :D

 

Travis, I must have pics of your build

i am down in corvallis at school, and the car is in woodburn in the shop. just waiting for the strange front struts and then we will start doing some cutting. ive been gathering pictures and might start a build thread.
