Get the transmission, driveshaft, rear diff, and rear axles. The stock parts should be fine for n/a builds but if you are adding lots of power they aren't made for that. Good news is Honda AWD swaps are kind of taking off and various companies are starting to offer upgrades for this stuff.
FYI there is also a billet H22 AWD bellhousing in development that will accept the B-series transfer case. This may ultimately be the best solution for AWD Preludes because using B-series transmissions requires the engine to lean forward, even with an H2B setup. The overall fit in the engine bay just isn't as good like that, having it lean back a bit like with H-series / stock engine is much better.
Here is an example of the prototype diff mount that was made for the S2k rear diff, however this idea has been scrapped:
The current idea is to only support the CR-V/Element rear diff and develop one mount that will fit on 2WS and 4WS cars. It should look very similar to this.
Currently this project is waiting on one vehicle to leave my property then I will be able to bring up the development car and make further progress on it.
Ok, so this happened just recently.
Thanks to Brian Spiker(TransLab Performance) and Aaron Lopez(driver) but they have been working on the AWD H22 billet bell housing that will allow any H22 owner to transfer their OE guts over and become AWD with the K24 tranfercase.
This changes everything because it eliminates the need for he H2b adapter kit to go AWD.
There is no confirmation on my kit for fitment issues yet but in time that will get worked out.
Check this thing out!!!
Needless to say, the whole game is change now...lol!!!
Ok, so this project took a hit, due to finances and lack of time.
We should be moving the car to the shop that we will be tearing into the car to start mocking up parts.
Wow someone finally made awd for H22 that's awesome. Wish that was around when I did my 3g H swap.
Hey 1funryd this is Dustin aka 91JDMsi from like ten yr ago when I bought the az H22 mounts my lude is up for sale if you know anyone interested 5k call me at 865-599-9346 thanks.
Good Day! A little help please?!? (I've searched for hours, found similar problems with possible solutions, but nothing to help me, so decided to post. Just FYI...)
Sometimes, for no apparent reason, it won’t start!?! Then sometimes it will after a short time, but other times it won’t no...
Hi, I recently acquired Duckeedoug's 1991 Prelude blue Si. He was extremely meticulous with the car's upkeep, and the overall body and interior looked fantastic for being almost 30 years old. Alas, he had two engine failures during his ownership, and decided to offload it.
I'm originally from...
Hey guys,
I think it's finally time to start the process for a motor AND transmission swap for my '91 Prelude Si. The car currently has a B21A1 with an automatic transmission. I'm looking to go for a H22 swapped from a 92-95 Prelude with a 5-speed manual transmission. I'm in the process of...
I'm taking the initiative, hopefully this will end up being stickied, so that I can be immortalized in my glory for such a brilliant idea.
So here you go...if you're new to preludepower, or if you're too stupid and lazy to use the valuable search tool, or if you tried searching and you're...
Ok so I did the head gasket on my 89 b20a5. I believe I had the timing like a tooth off it was real sluggish and wouldn’t idle. I was taking the valve cover off to check it and me being stupid didn’t unhook the battery and ground out the alternator wire. It blew the main battery fuse so I...
