ive done a substantial amount of searching on this subject and all i can seem to find is people saying that its been done before and you need an adapter plate. I cannot find any write ups about the specs of the plate or why you even need one (i havent personally compared the specs of the two trannys so i dont know whats different about them other than ive heard the b16 trannys input shaft is longer)

so if anyone could please link me to somewhere i can get specs for an adapter plate id appreciate it.

also ive found adapter plates for b-engine to d-transmission, and this doesnt make any sense to me as far as performance. the b-transmission has a closer gear ratio compared to the d-series which ultimately means faster acceleration and it stays in the engines power band more. correct?

i have a mini-me swap in a 94 del sol and im looking to do a b-series transmission swap along with a turbo.

 

BUMP

 

Some info here: http://www.d-series.org/forums/diy-f...r-own-d2b.html

Honestly for all the trouble to go through, you could just get an aftermarket final drive gear for your stock transmission, instead. I used an online calculator before, and figured out that the 4.5, 4.7 & 4.9 final gears in the Z6 transmission ended up being pretty close to the gearing of B-series transmissions.

A cheaper option to think about, rather than buying an adapter plate kit, that will likely cost around $1,000.

 

there is no one currently producing a plate for the d2b, but you dont need a plate it can be done with out using an adapter. but in all honesty your not ever gonna get the hp out of a boosted mini-me to ever utilize a b series transmission. your best bet is to just use a si/ex trans thats plenty enough trans for a boosted street car, unless you are planing a 600hp build

 

why do you say that?

im only following through with my mini-me swap because i already started it. in hindsight i wouldve liked to buy a b18 and then a b16 tranny wouldve bolted right up no problem but at this point thats neither here nor there soo...

im not looking to get an outrageous amount of hp out of this, but i want a fun DD for the summer, and i know for a fact the shorter gears would make a noticable difference.

im also interested in finding out if 1st thru 4th gears/synchros of a b16 tranny would fit on the mainshaft and countershafts of a d-series transmission, in which case you wouldnt need to do a full transmission swap, which from what ive read from the link above, you need a custom flywheel along with some other fabrications.

 

Aside from the b series tranny also using an intermediate shaft which botls to the back of a b series block to allow for equal length drive axles meaning less torque steering under hard throttle.......my advise would be to just change your engine over as well!

If you are going to all the trouble trying to mix and match, and spending money for adaptor plates and such, why not just pick up an LS engine for $300-400 and drop it it instead? It will make more power than you have now because it flows better, plus it is very turbo friendly, and oh yeah, it's stronger

 

Really No one?

Its not just the Gear ratios your after, Better axle options, Halfshaft, Stronger Tranny, Are just a few reasons.

Do some research before you make an uneducated post

 

Precisely what i was looking for..

THANK YOU!

 

did you ever hear of the term k.i.s.s. or keep it simple stupid. i say your not gonna make enough hp out of the mini-me because well your not you dont need to think about the b series trans till your well over 500hp. and lets face it i dont think you aiming for an over 500hp build, im not knocking you intelegance but from the posts you have made about your build your not ready to plan and exacute a build like that so as i said just build and boost the mini-me and use a dseries tranny it will be hold up to more then you will throw at it that is if you know how to drive

 

i knew about that plate but th last i heard it was super expensive and not available to the public yet, now it is expensive but useful for one who needs it. and i just dont think the op needs it unless he has money to burn on useless things that are not needed for his build but hey if you feel you need to spen 800 dollars to use a b series tranny for your 250hp build then by all means go for it

 

i just wanna make myself clear...

im not planning on doing this swap because i plan on making high hp and am afraid of breaking the transmission. ive done some research on the subject and from what ive read, any transmission with a close gear ratio will accelerate faster than a transmission with a wider gear ratio, it will also stay more in the power band with closer gear ratios. if you put the specs of the two transmissions next to eachother (specifically a 92-95 D15B7 transmission compared to a JDM B16A J1 transmission) 1st thru 4th gears of the J1 transmission are closer than the gears of the D15b7 transmission. having closer gear ratios compared to wider gear ratios will make a noticeable difference in acceleration, it doesnt matter if you ride a 10-speed bicycle or a 5-speed civic.

now im still learning about all this but im pretty sure that im accurate about what ive said.

 

which is why im doing research AND asking questions

 

Thats all true info, but its not in any way cost effective. Its would make a lot more sense to either run a D16Z6/D16Y8 tranny with an aftermarket gear set and final drive or build a hybrid tranny (you can use a VX third gear as a really short 4th in an EX/Si tranny and its cheap) or finally you could use a CG tranny out of an '86 - '89 Integra and adapt it fit you civic (been done before, its geared pretty close to a B-series tranny and it bolts up to a D-series engine)

 

I asked about that earlier, if the gears were interchangeable between transmissions, because that would be a much easier option

but no one answered that question.

 

you asked if the bseries trans gears would fit in a d series transmission and that answer is no. and no wonder you dont want to listen about the d series trans cause your comparing the b trans to a d15b7 trans and well the b7 trans does suck and has wide gears, but compare your b trans to a ex or si trans from a z6 or y8 and i bet it will be quite abit closer, ive used all the different d series transmissions and for stock transmissions the ex/si is the best tranny, but for my boost cars i liked the b7 trans better as i felt the ex/si trans was to close for boost cause you were having to shift so fast and was way to snappy for the street especialy for a dd, my car ran 12psi and was at full spool at 1600rpm and carried it to 7k it was so snappy that if it was raining that it was hard to drive safely and i put the b7 trans back in and it tamed it down a bit but it was still plenty quick

 

the j1 still has better gear ratios than the closest ratios of any d-series transmission. i have compared them, and i still wanna do it.

 

you dont want a b16 tranny and turbo. that would be stupid. you want a ls or maybe even a gsr.

 

why do you say that?

 

You do realize that a B-series hydro tranny is going to in most cases run you $500+ for something that doesn't need to be rebuilt along with an adapter plate you're looking at over $1000. Sure sometimes someone gets a deal, but thats not normally the case. For the money buying an aftermarket gearset and final drive makes way more sense. Or just do a complete B-series swap.

 

im not entirely worried about the cost as im not planning on doing this immediately. but i should be able to get most of it done by next summer.

 

hard to justify.. meaning D15B JDM Tranny will fit to B16/B18/b20?
havent tried this one on honda motor but I think it'll work since we
have it tried on other motor like Nissan b13 1.6 engine and tranny 1.3 also tried for other brand but for demo and it shows significance.. I might make a fun of this D15 for B series.. for sure I'll scrath my
head but worth doin

 

You'll be a lot happier just doing a cheap b-series swap.

Do a b18b + your pick of a bseries transmission. It will be cheaper, higher displacement, and a stronger bottom end.

Not to mention you won't need a ridiculous adapter plate.

I get the impression you're making your life harder just to be different. There's a good reason "d2b" adapter plates are few and far between. Because instead of wasting money making a d-series setup better, you could just get a b-series.

 

yes and no. im also stubborn. and i like to experiment and over enough time ill be able to get all the parts i need to do it.

 

that makes absolutely no sense. All B series come with those trannies (why its a B series tranny) and they all make less power than a boosted D series.

Although I do agree that a si/ex tranny is fine for a boosted street car.

I'm not sure exactly how to put a B series tranny on a D series but I know its possible. This car I saw yesterday had a boosted Y8 with a Type R LSD tranny.

 

Well if you are doing it solely for acceleration reasons then its a complete waste of money. For the amount of money you are going to waste putting a B series tranny on your D series you could make the D series much faster by just using a better turbo or more boost. there is really no point in spending the money to put a b series tranny on a stock block D series. If you have a built D makign a ton of power and you were looking to go faster then ok. But in the power range that you want to make its not going to make enough of a difference to justify the price.
