Well guys, after reading a shitload and finding Mista Bone's old website about D series hybrid transmissions I decided to embark on a little side project to get me by until I finish the K swap, which is still a couple months out.

First off, I have a 93 cx hatch that is lighter than hell. It is equipped with a 96 d16y7 non vtec. It has a z6 intake manifold and tb, and B series intake arm. I'm running a p06 stock map, which is not correct for my d16y7, but it does fine. I think there is more power to be found with tuning, but fuck tuning, its a D series.

This motor is my little bitch until the K swap is done and I rape the shit outta it daily, but my long ass cx gearing was driving me nuts. I have about 5 D series trannys laying around from all the swaps I've done in the last year or so, some fucked up some in good shape.

Well I got bored after class friday and said fuck it, I'm gonna build myself a hybrid trans.


So first off, 3pm, start pulling transmission. 4pm got trans out.


So I start tearing apart all the old trans'



and then I clean up a B000 case for the new trans


then I put it together and throw it in the car. Finished by 9pm yo



and then today I go test drive and GOD DAMN, this thing is a badass D series.

This has to be the quickest NA D I've ever been in or driven for sure, and its non vtec lol.

For the trans I used d16z6 1st and 2nd, dohc ZC 3rd and 4th, and my old 5th for the gas mileage. I also used the 4.250 final drive from the SI trans.

Here is a video, pardon the quality but its hard to shift and camera at the same time. Keep in mind guys, that I'm at 6200ft elevation, that adds a good 1.0 to 1.5 seconds to our quarter mile times, if not more, so be nice. This car is most definately 100% postively faster than my b18b1 swapped eh3. obviously my weight is the big difference here but I highly highly recommend this transmission stuff to everyone who plans on keeping a D. Its by far the best thing you can do for power outside of boost or nitrous.

Here is the pretty girl herself

 

how angry were you when you wrote this up?

nice job :thumbup: on a scale of 1-16 how hard would you rate something like this?

 

haha not angry at all, but I was angry friday afternoon when I was doing this, and I was trying to portray that anger I was mad because of my shitty gearing so I had to fix it

on a scale of 1 to 16 lol, well lets put a b16 swap at 8, for reference, and an h22 swap at 12 or so.

I'd say this was about 11.

also my timeline is somewhat inaccurate. I pulled the other cases apart the night before.

but I did the entire trans swap and the building trans process in about 6 hours, but then again I can pull these things out quickly

 

an 11 i have an ex tranny. is there much room for improvement?

 

no I wouldn't mess with it. You could use the ZC 3rd and 4th but its not worth the effort.

If you ever blow that trans or want to install an LSD however, It wouldn't be much harder while you have everything apart

 

u got a link for the hybrid trans?? I rebuilding the trans my bro blow up so that i can put it into my car. And that is something im been looking for. So did that PDF help?

 

http://home.cinci.rr.com/mistab0ne/tranny.html

that pdf helped a lot. Thanks for that man. I meant to say it in the other thread but forgot

 

damn that's a sweet setup.

 

I glad it helped. im gonna to be using the dX 1 and 2 and then the SI 3,4,5 it should be a helluva lot better than the CX i have in there now.

 

yea the main thing is switching out that final drive ring gear to the 4.250.

The Cx's 3.250 is what kills it.

Getting the shifter forks to line back up was probably one of the most difficult parts. Just had to shoehorn the thing in lol. It has those three tabs at the bottom that connect to the shaft that is connected to the shifter selecter.

Well you have to lift that shaft all the way up, and then it still barely will slide in, and then you have to pop it all down. After that you have to realign the guide bolt, the 8mm allen head thats in the bell housing. If you don't line it up right you won't be able to get into 1st, 2nd, or 5th.

My friend liked this trans so much that I might be building another one for his 92 cx. If I do so, I'll probably take my time and maybe a writeup for you guys, which would bring the difficultly down to 8 or so.

Also if you don't swap gears, only final drives or just entire gearsets, its much much easier. Its pulling the individual gears apart that gets a little more complicated
