All Wheel Drive Project


After a decade of debate on the subject, 1FunRyd and associates are teaming up to finally produce another 1FunRyd aftermarket option for the 3rd gen chassis.

1FunRyd Performance is working on the: All Wheel Drive kit for the H2b and B16/18/20b kit that 1FunRyd currently supports.

We have already completed the standard B-Series kit project and here is my personal car below running and reliable.











1. Working on the rear wheel setup:




All Wheel Drive video:



We are excited to finally start this project because the approach we are using for this project is to build my Custom Engine Rear Sub frame which will mean that I will be able to redesign my H22, B-Series and my future K-Series kit to accommodate all the engines and bring them higher up into the engine bay to allow for better ground clearances.
Stay tuned for updates as we solve one issue after another... ;)

Wouldn't this pretty much work the same as any awd civic converison? say doing h2b with crv components? or is everything going to have to be crazy custom? Was thinking of doing the h2b awd in the 5th gen.
Has anything with the 3rd gen swaps been common? No.
So the same for this swap.

We are building a custom subframe to address many of the issues to accommodate this swap, it will not solve everything but it will be a bolt up scenario with the custom parts we make and it will allow for more flexibility to do swaps whether its just FWD swaps or AWD swaps.

If you attempt to do this on your own, without the correct information then this will be the most expensive thing you ever do with this chassis.

Any updates on progress?
We got the bearing back for the rear knuckle and test fitted it.
That bearing will work for a hub we chose, however we are looking at other options to use to try to keep this project/skit more affordable.

Custom options are an option but we are trying to use OE options as much as possible to keep costs down.

We have started on the custom 1FunRyd Subframe for the engine to replace the rear subframe in the engine bay to all for better clearances and also to all fore future changes or add-on's for my swap kits and other things.


So you will be attempting a K-series kit also?
Referring back to my statement above with regards to a custom rear subframe has started.
The only way to make room and or stuff cerain motors in our chassis and gain better ground clearance without cutting the frame or the hood is to make a custom subframe which I have been talking about for years.
So we are making headway there.

Any new updates?
1. We are 95% finished with the Jig to make my custom K-Frame to replace our stock one so it will allow more room and better engine placement for all motor swaps.

2. The rear knuckle situation is figured out to reduce overall cost to customer and me alike.

3. We are waiting on the rear diff that we are going to use on this project which is a Subaru diff. We are still going to get a spare CRV rear diff for those who want to stick with the CRV overall power plant.

4. Hubs have been figured out, just need to get them all done, but since that is one of the easiest parts we are waiting on that after we get the rear diff on hand.

5. The rear diff part is still on hold until we get the diff here in hand and then we shall be making progress on that.

We are moving on this, once we get our first prototype K-Frame done and tested in our current H22 chassis it will be opened to the public for sale.

So the subframe will be road tested first, and then as we get all the parts in to assemble the entire car, we will test that as well. The full testing will be done in phases as we make sure we road test all parts.

Which year & model Subaru diff are you planning to use & why?
The subie diff is going to be a one off.

The main kit is the CRV/Element which we now have both in our possession.




This is the subie diff on just a comparison mock up.



As it stands the subie diff has a much deaper bell housing which means 4WS will need to be given up unless we cut the bottom of the chassis and make a brace much higher in the chassis.

For my kit I want as much bolt up and no cutting as possible since I am trying to make this a kit that can be installed by most enthusiasts with some basic knowlege and tools.

Depending on how we engineer it, there still maybe some customizing on the chassis side for the user.

So all that bitching about me putting a k series into a third gen prelude....only for you to come back 2 years later and do the same??tsk tsk Sean


with that said tho ; this is awesome!!!

ive been worki g on an adapter plate to mate the honda j32a2 v6 to the suburi awd transmission. Planning on making my 5th gen jswap awd.
lol!!! The only reason was because of the engine placement which required cutting the hood.

But with my new subframe, that changes the game, and also increases the cost of the swaps now if anyone wants to do a swap with better ground clearance...

But I have not done the K swap yet so its still up in the air...:lol:

And to the J32a2 swap AWD...that is also awesome!!!

Will 4WS be retained with either differential setup?
Due to the bigger rear diff of the subaru, 4WS cannot be kept without sever cutting of the chassis which is no where the current customer wants to go.

The kit we are developing is mainly for bolt up as little to no modifications as necessary.

The CRV setup however will be able to keep 4WS.

So any idea on ETA for this kit? maybe early 2019? heading out tomorrow to pick up a 91 project car with a blown motor....AWD is a dream of mine
We are still working out some driveline issues and rear differential issues since the current project is being made with an S2000 rear diff.

We have to put a holt on things until we get the gearing worked out due to steering issues with AWD.

Any more progress so far?
We have the subframe for the rear done, and we have the prototype for the front K frame that replaces the OE K frame.

We will be test fitting things in the up coming weeks, we just have to get the NSX running first so it can be driven out on its own power.

Any more updates?
prototypes of the front and rear sub-frames done. But need to be tested.
We are now able to get more space back in the shop, my truck was one of the issues due to we used it to haul metal and parts away.
Is movable now but still not road worthy.

We should see some more progress in the next month or so.

How much power can that crv rear diff hold? Would be awesome to do a turbo awd setup pushing high numbers without grenading diffs every time you launch.
Not much at all. 250whp has been the number floating around, but I personally believe around 230whp is probably max.

So, my dream of having a boosted awd third gen is out the window then?
No, just need to change things in the swap to make sure it can handle.
Like getting an upgraded transfer case, and use a different rear diff to be able to handle the power.

This means a custom transfer case, and customized rear diff from a different car and then get custom cut gearing in the rear diff to ensure that the rear and front turn the same.

You can still boost the B20vtec and push the setup, you just need to do the research to see what combination works.

So I know you are comparing the crv and subie diffs. What about any nissan rear diff?
We are going back to CRV diff for this project. Due to cost and timeline.

The issue with awd systems is that if your diff is not the same gearing as the transmission then you will have issues with turning.

Very ambitious project Sean, although I can't say I'm completely surprised that you would take something like this on. I'm interested to see how this turns out although I am a little more interested in the K swap idea.
The K swap may be still on the table, but for now its not a high enough demand.
Still only 2-3 serious buyers of that kit and all that will be associated with it.

U can add me to that list of buyers. Would be nice to have a K.
Should I get enough backing I will do that.

Anymore updates on AWD setup?
As of now not yet. I had an issue trying to figure out the rear knuckle for the hubs, but I finally got that all worked out.
So I am currently waiting on scheduling with the fabricator to get the missing parts we need from one location to the other to get started on the nitty gritty.

So what are you guys hooking up to for the rear subframe? Are you cutting stuff out and welding in new tabs or using existing mounting points?
We are using the new subframe we came up with for a bolt in solution.
