    Had a bit of time to test fit the drivers side axle today. I had the option of two different lengths tested longer one first and it was about 1in maybe two too long. The second shorter one fit like it was meant to be. Oem integra axles ftw. Here is the photo of it Installed I'll work on the other side in coming days.

    Re: PROJECT: A20A to B18A Tranny Adapter Plate

    Okay, so quick update, so I was able to swap everything out and put it all back together and drop in the car. I had to modify the front mount just a bit to get that mount 100% bolted down but its in now. Drivers' side mount 100% bolts in nothing changed there. Rear mount the top two bolts, and one of the bottom bolts are in so that 3 out of 4 there, I'll call that 75% but even with just those 3 boltded up and rest of the mounts the motor doesn't move at all. If you recall, the rear mount is the one that needs heavy modifications and/or redesign. This I plan to work more on with Dana Prum in the near future.
    I've tested the shifter now that everything is bolt up and sitting in the bay correctly. The shifter is smooth, fuild, and responsive. The clutch cable bracket work and hydro to cable conversion kit work's great. The pedal is stiff from the exedy stage 1 clutch kit and flywheel but smooth and responsive like stock.

    At this point, the only thing holding the a2b from being 100% is a test drive. The plate itself doesn't seem to need any other modifications outside of the starter holes cut during production, which will be done.

    The test drive will happen as soon as I get my car together, which I've been working on all week. Here are some photos to hold you guys over. I'm editing a video and have one more video to make after.

    Well, I'm putting the final touches on the project. Here is the last thing needed. To make room for the intermediate half and the mount plate, the black box has to be deleted, and the oil returns neck needed to be cut off and then welded shut. Now, for me, this is a problem because I planned to delete the black box and run a catch can anyway as my build it's going boosted.

    Man I have updated this in a while sorry about that definitely more on top of fb and yt but a lot has happened over the weekend and there will be a video to go with it all but for now the latest is that everything is in the car mounted bolted up and ready to go.
    mounts have been redesign/made and fitted/welded to the car so there is no going back, starter engagement has be tested and is functioning properly, shifter cables functional, Clutch cable to hydro conversion functional. But the car doesn't start so I'm not able to test drive it at this point. As mentioned before the car was taken to my friend Dana aka youngstatic on yt to have some work done related to a2b and my turbo setup so I could get ot dyno tuned. That did go as planned but all the a2b stuff was taken of. The car cranks but didn't start so no test drive yet. More on that in a yt video but for now here's the photos

    I hope you get it running soon, its currently fwd though right?

    What is left in the process of releasing the tranny adapter plate? Is it going to be released solely through your fabricator or are you going to be able to release a dxf file so anyone can make it if the send it in somewhere like sendcutsend?

    Yeah its fwd right now. The awd stuff is gonna be a while as I'm gonna need to develop a lot of parts for the rear end. I'm sure I'll have get rid of the double wish bone rear suspension to make something work and a whole Lott more.

    As far as the plates go. Allen built will produce them once I tell it's a go only thing stop that us a test drive. I want to be 100% it's gonna to work before I give him the word. But as far as the plate goes there's nothing really stopping them from getting ran as is

    Re: PROJECT: A20A to B18A Tranny Adapter Plate

    What about fwd trans compatibility? Starter is in a different location, so if anyone wants that should we just forgo the starter hole in the current design or leave it and cut a new one? I for one am wanting an S80/Y80/S4C trans and I want to keep the shift linkage. I think everything else looks good in terms of compatibility

    Did you end up using a stock mount for the trans or what is that? I see the custom part you welded to the frame.

    And mainly the steps to do the swap are:
    Add passenger side mount bracket to frame
    Modify rear mount
    Modify alternator bracket and sump drain for jackshaft
    Mount made for jack shaft
    Fit integra axles
    Shifter depends on awd or fwd
    fwd trans need a traction bar

    So the video I'll post after this will clear things up about the side mount so check it out then we can go over that more in depth if need be. Dana just posted a video about my car and some to things I got going on to his yt today.

    As far as fwd vs awd stuff is concerned I will make this as simple as I can and have stated before you can remain fwd with the awd transmission/case. You don't have to go awd to use the awd transmission case. If you would like to use a fwd gears stack you can put that in the awd case and remove the transfer case from the transmission and block off the hole. There is only one part you need to make this possible. It's the speed factory awd to fwd Shift Fork replacement. Every thing else with a2b would the same you just install the Fork can swap out the gear stack that simple. Need to redesign the plate or use different Shift linkage, cut new starter holes ect. I've mentioned this in past post (or at least I have on the fb thread).


    As far as the list yeah you got it 90% right. The axels are gonna be thing that kinda of tricky but not really. The halfshaft side is dependent on the what halfshaft you run. If you have a teg you can run a teg axel if you have a crv you'll need a crv axle. Kinda straight forward. Passenger side would be a crv however you can fit a teg axel in a crv Transmission sooooooo technically speaking you could run either. For example I have crv Passenger side axel and the halfshaft is from a teg because at the time I didn't have a crv halfshaft to use so I have to use a teg drive side axel. But I can swap the halfshaft to a crv then use the just crv axels. However I would have to make new mount because the halfshaft mount holes are slightly different. Seeing how this is up the each person(maybe working with Dana to make mass produce them both) that's really up to you.

    Other then that you got it spot on. I just would focus on the awd vs fwd transmission so much because there is a work around that make this setup usable either way its most fit of the bell housing and rear mount and clearance in the bay that make the awd case more useful in the long run. Even if you plan to fwd only if you later want to join the awd crowd you can and still keep you fwd gearing with a single part.

    Re: PROJECT: A20A to B18A Tranny Adapter Plate

    And we have a test drive. A2b is fully functional. the car needs a tune so I wasn't able to really drive it drive it but here is one of a couple trips around my neighborhood. At this point there is nothing really left to say/do. It works this is proof of concept. I can most likely have Allen roll the plates out just have to let him know.
