does anyone have pics of the h-d adaptor plates?

Whoever said having a d motor to b trans adaptor was a bad idea is a dumbass. For those of us who have d motors that make power up high (8000-8500) it would be a great idea. there is a guy on HT who is just finishing up a turbo d16 drag car with a b series trans. Even a 94+ GSR trans has equal 1-5 but better final than the zc/si hybrid. Once you factor in a type r or 92-93 GSR trans, forget about it--you will never be able to match that with a d-trans unless you want to spend $1500 on your gearbox which at that point you can't just go to a junkyard to replace your $2000 custom 1-5/final d16 box. I have had disagreements with people over this before and for the RIGHT application I think a b box d motor makes a hell of a lot of sense. As far as Houseman goes, I don't know the prices for d series gears but for 84-87 crx/civic FD--he wanted $1500 a piece. Ouch.

That's right, I am a dumbass. You're right, the GSR trans has a "better" final drive than the stock civic ex/si 4.25 final drive.

But then again there's the 4.4375 zxi final drive
71/16 = 4.4375

And even without that 4.4735, the 4.4 is only 3.5% shorter than a a 4.25

infinitude 3/5 gearset is $525. you use the stock 3rd as 4th.

1.9 / 3.25 = 0.5846
1.565 / 1.9 = 0.8236
1.25 / 1.565 = 0.7987
1.0 / 1.25 = 0.8

Taken from my transmission page (http://thebense.livejournal.com/56502.html)

GSR transmission
1.900 / 3.230 = 0.58824 or 58.824%
1.360 / 1.900 = 0.71579 or 71.578%
1.034 / 1.360 = 0.76029 or 76.029%
0.787 / 1.034 = 0.76112 or 76.112%

B16/USDM ITR tranny
2.105 / 3.230 = 0.65170 or 64.170%

1.107 / 1.458 = 0.75926 or 75.926%
0.848 / 1.107 = 0.76603 or 76.603%

why not make a adapter plate to make a b-series tranny to fit on a d-series motor? or are those already made?? but a dseries tranny on a bseries motor is just whack y0!

i would buy one...you can pick up ls longblocks for cheap and then just put it in your car using your stock mounts and axles...sounds like a good idea to me

People also told me for years that running Hondas were "whack". Then the turbo guys say all motor is "whack". Then the Honda folks told me running a SOHC was "whack". Now making adapter plates for a variety of applications is "whack".

Maybe, "whack" is the way to go! It seems to be a win-win everytime.

im def going to be pickin up one of those h2d adapter plates for my f23 motor...

bisimoto how long is the waiting period on recieving one of those plates?

changing from b series to d series makes no sense this is rediculous

d16dcoe45

Hey Bense--I wasn't referring to you. I was referring to Mitsuman when I said "whoever thinks D motor to B trans is a bad idea is a dumbass"--and I stand by my statement. What I really don't understand is why anyone would want to run d trans on a b motor. I just found out about the M's Factory (I think that is the company?) who has either 4.50, 4.70, or 4.90 FD for d series for like $500, they also have a close ratio 3-5 gearset (forgot the ratios) for d series for $625--So for $1100-$1200 you can keep your si box and have a killer d-series trans setup. But if you already have a b series motor and trans, you have a great selection of factory gearboxes (and a ton of different aftermarket gear choices) Which for even the best type-r box will still be equal or cheaper than a built up d box with similar ratios--I just don't understand why anyone with a b motor would want a d trans. I can understand an F or H motor--the d or b trans makes the swap easier plus you get rid of the cable shift of the f or h (not that the cable shift is necessarily "worse")

im assuming you use everything d series with h2d just the like the h2b setup.. d series mounts and all.. what comes in this kit?

Bense

Now that I think about this more and more, I can see an actual use for these B2D setups. Hopefully it will provoke more aftermarket trans parts for the D-series.

I want a 2.45 1st gear

.:Swig:.

i vouch for it

I do stock them, and make more whenever my inventory runs low. I have them available for immediate shipment.

It comes with my signature half-moon plate, custom aluminum flywheel, custom 8.8 grade bolts, and instructions.

I can see why there is a need for this. One can just buy a B engine, retain the stock linkage, axles, tranny mounts, clutch, and voila: a simpler swap without the expense of B transmissions. You should really take a look at how many B trannies break in the all motor class even with 220whp! It will be a cost effective kit, in the long run.

Bense

D-series trans stronger than the B, who woulda thought!

if you can help get one produced for less than $500, put me on the "I will definitely buy one of these" list

hybridpatient95

thanks bisimoto...

what tranny do you recommend for drag racing?

also what mounts would i need to use all d series?

also with this setup the motor will sit pretty much like a h2b motor does i assume?

axtran

speaking of low rpm... one of my managers at work has a '92 Ford Mustang LX 5.0 with a Lincoln Mark VII Auto Trans and does 1800rpm at 80mph. That's sweet.

Other than that, I guess someone who doesn't know how to drive stick for crap could benefit from this part :-D

platinum00

D to B conversions make sense. B are stronger proven trannys, you can fit stronger axles in the tranny. you have alot more gear options, clutch options, etc...

B to D conversions just dont make any sense. The only reason to do this would be if your not going to make much power and already have the D series tranny lying around. Saying it's cheaper to replace if it breaks is just dumb. why would you want to keep replacing the tranny?

A high horsepower D series is what 500whp. people are having problems at those power levels. A high horsepower B series is what 800whp. There is no way in hell a D series tranny can take that abuse.

FYI. I currenlty run Y8 tranny so im not a biased B series guy.

hey did anyone ever think that a b series conversion to d tranny would be really nice when it came to the 4wd wagovans! thats what im trying to do right now because i spun a bearing in the d motor and i have a fully rebuilt b20 laying around so y not put that in. b to d is a good idea when it comes to that.
