Default d tranny to b20.. will it fit?

yeah im rockin a 90 crx si with a d series motor.. and well i just got the tranny refurbished and a new clutch... im planing to instal and b20 into my car and was wondering if the d trany would fit the b20 and if it would work aright.. cuz id rather save some money and use the almost new tranny for a while then step it up and get a new tranny altogether for the b20.

^^ here's a similar thread about d tranny with b motor.

it doesn't seem like there is a adaptor plate, etc. currently available. the OP in the thread I posted claims to know someone that will fab them but I dunno

I don't think there is an adapter available, as there is with other honda trannys. GL but I believe it is a solid No

D series = d series and b series = b series. Therfore you must find b series tranny to bolt up to b20. Good luck get the ls one for taller gears for fuel economy and built your way up.

On a lighter note, if you have a nice D series tranny you want to sell now, I may be interested. I would like to know more about what was "refurbished".

Hit me up. If the price is right, I will contribute to your quality B series trans fund.

I can't see an adaptor plate working for this application. Given the position of a D-series transmission, the driver side frame rail would be in the way of the engine if you tried to use a D-series transmission with the stock mounts and an adaptor plate. Remember that the stock placement of a D-series transmission was made with a shorter engine in mind. Of course, I could be wrong about the clearance issues, as I have never actually seen a B-series motor mounted in this way. But regardless, I have yet to see an adaptor plate that is remotely cheap. So even if it DOES fit, it is probably not the most cost-effective way to go.

I'm just reiterrating the fact that a B head wont fit on a D block, and vise versa. And apparantly "I missed the bus".

i believe they are talking about D series transmissions working with B series motors. you came out of left field talking about mating B series heads on D series blocks. way to bump up a dead thread with irrelevant information, chief.

But I can see some REAL clearance issues here. Comparing my 1989 DX to either of my B-powered cars, the bellhousing on the DX is about 1-1.5 inches closer to the driver side of the car. Add another .375 inches (at least) for the thickness of the plate, and I see problems. At the very least, the driver side frame rail is going to need to be notched to make room for the crankshaft pulley (clearance is pretty tight as is with a Hasport kit an B-series transmission). And the timing cover is probably going to be close to touching. Needless to say, as a best case scenario, timing belt replacement is going to be difficult. Add to this the fact that Bisimoto's other adaptor plates cost $700+, and you are going to have to REALLY like D-series transmissions if you still want to go this route. The only REAL advantages I see with using a D-series transmission are the cheapness and disposability factors of D-series transmissions.

Also consider that if you want short and tight gearing, there isn't a D-series option comparable to, say, the B16A transmissions or the ITR transmission.

The Si is plenty short. With a B16, it would probably be inbetween the b16a tranny and the ls, wich would be perfect actually.

I will buy one. Just to see.

since when has clearance issues stopped true enthusiasts? i do think it has advantages over a B series trans. especially on cable actuated transmissions. there are way more D series transmissions floating around the US than their are B series transmissions. D series transmissions are cheaper too. by a lot. Bisi seems to think the D series transmissions internals can handle the abuse.

yes, even the B series LS transmission actually has a better gear ratio than the D series SI transmission. the use of a half-shaft, in my opinion, is better when using a B series transmission. hopefully the plate does come out, because maybe later a D2B adapter plate would come out. think of a well built D16a6 using a Ys1 transmission. talk about total sleeper.

the LS has slightly shorter gearing than the SI which means better acceleration.
