AWD Xtreme Build

So I’ve got an idea but could use some insight from some people that might know a bit more about what I’m wanting to do. The plan is to turn my Xtreme into a Xtreme Syclone. However I want to LS swap my truck and still make it AWD with a 6 speed manual. I don’t know what manual transmission I should use not do I know what AWD transfer case will mount to that transmission. Any insight would be great. Thanks

Re: AWD Xtreme Build

What is your mechanical background/abilities? What kind of budget can you throw at it. If your a high school kid working at McBurger flippers, the chances of this coming off are pretty slim.

I don't mean to sound like a Debbie Downer, but a lot of high end plans die on the vine.

So I’ve always done my own mechanical work on my cars and most of the body work as far as making body kits fit. I just don’t do paint or dent repair. I haven’t ever dealt with drivetrain repairs or swaps so this is new territory for me but I’m pretty sure as long as I know what I need I can do any fab work to make it operational. As far as my budget goes it’ll take some time but I’m a quality tech in a manufacturing warehouse so saving the money to buy the necessary parts won’t be a problem.

Re: AWD Xtreme Build

I haven't done this conversion but I do know you will need the front diff out of an Astro van with AWD. All Syclones were automatics I think so I don't know what manual and AWD transfer case to use for the conversion. hopefully, someone else knows what might work to do a manual. I thought about doing the same to my Xtreme, but came to my senses and realized how much money it would take to do it right and decided to just try and save up for just an LS swap in the future. I bought an AWD turbo car for my adrenalin rush! Good luck!

Re: AWD Xtreme Build

The first hurdle you'll have to overcome is the fact your truck is currently 2wd. To make it AWD you'll need to swap the body on to a 4WD S10 chassis that has the same wheelbase. By using drop keys on the torsion bars and rear blocks you will be able to lower it somewhat.
As far as adapting the AWD 90-98 Borg-Warner 4472 transfer case out of a Bravada or Astro van goes, try contacting Advance Adapters to see if they make a kit to fit that TC to a T56. The Syclones were automatics IIRC. You may have to settle for a 5 speed. A 4wd NV3500 would bolt right up to the Bravada TC with the right 4wd GM adapter. IDk if it's the 5 bolt or 6 bolt one. Depends on what year trans and TC. Try getting it with the TC.
You don't want the NV 136GM 99-05 TC as those are computer controlled electrics.

Yeah I’m sure there is a way to do it but like I said in my earlier post. I haven’t ever dealt with anything as far as driveline or transmission issues or swaps so I’m not sure what I’m looking for. I know it’s just a transfer case that is used to make it AWD and I know there are transfer cases for manual transmissions but I have to figure out which manual transmission I want/need to use and then locate a transfer case for said transmission. The rest I can piece together pretty easily.

Re: AWD Xtreme Build

When you're done the only part of your Xtreme that will be original is the sheet metal. I might be easier to find a 4WD 4.3 5 speed RCSB and just put the Xtreme kit on it. Then do the AWD swap. Then lower it. Then do the LS swap. Rather than completely taking apart your entire truck all at once.

Re: AWD Xtreme Build

second a this
doing all at once will be a big pill to swallow
heres what I would do


find a 4WD chassis
get all the AWD stuff you need to convert the 4WD
put this all together while chassis is out
swap the motor out to LS
swap the entire chassis over from your 2WD


IIRC GM did a prototype of an LT1 AWD using a Sy as a basis
you might want to research how they did that and substitute the LS for the LT1(old style one)

Re: AWD Xtreme Build

This conversion has been done before. There are threads about it here at SSF as well as other boards. All of them start out with a 4x4 chassis & build up from there.

Here is an example - https://www.s10forum.com/forum/f307/...ersion-515441/

HINT: The 1GEN & 2GEN truck frames are nearly identical, so most of the information from the thread posted above should be of value.

Would be cheaper to find a clapped out 1GEN 4x4 & build up its frame, Then swap your body onto it.

Re: AWD Xtreme Build

There is one caveat.
This is going to cost a lot and take along time.
It would also be helpful if you are a reasonably experienced mechanic. You are taking on a big project.
Hopefully you have a well equipped shop and can devote one stall to this for a couple years.
Not trying to discourage you. Go for it.
Just keep in mind most simple LS swaps (if there is such a thing) take longer than originally planned and end up costing more than originally budgeted.

Re: AWD Xtreme Build

Im pretty sure the floor in the 4wd is raised in the transmission tunnel to accommodate the transfer case too. maybe easier to get a 4wd build it and stick an xtreme kit on it.

Re: AWD Xtreme Build

You bring up a good point. I've never tried swapping a 2wd body onto a 4wd truck, but was under the impression all same year, same model S10 cabs were the same. IDK??? Guys commonly swap 2wd cabs in place of rusted out 4wd cabs. Never heard mention of any floor issues.

No maybe about it.

Re: AWD Xtreme Build

I guess it bolts on, but the floor in my 4wd blazer def has a strange hump in the trans tunnel, that is not as prominent as the two s10's i have, but maybe its a pick up to blazer thing?

Originally I had this same idea but for now, I've got a 4x4 rcsb that will be getting the early bravada transfer case and axle tube soon. I'll drive it until the end of summer then start the LS swap. All of said goodies are sitting next to it now just waiting on time.

All of the research I did showed exactly what is mentioned above. WAY too much work to start with 2wd. I actually picked up a second rcsb 4x4 that needs some body work just because it was so hard for me to find one that wasn't completely rusted out. Hopefully I'll build that into something cool also.

Re: AWD Xtreme Build

I also had this idea at one point, I found the trouble with the trans was that there is only one company I am aware of that makes a t-56 magnum or TR-6060 that uses a 4x4 tailhousing that would allow you to mate it with and AWD transfer case. Look up Rockland Standard Gear Tranzilla, if money is no object it would be an awesome little truck.

Other than that swapping the AWD parts over from an Astro to a 4x4 chassis should be relatively straight forward. Then you get to deal with the usual 4x4 ls swap issues of differential/engine clearance problems.

Good luck!

Re: AWD Xtreme Build

Check out Project: Crew Cab V8 4x4 6speed. https://www.s10forum.com/forum/f30/p...-speed-609746/

T56 with an adapter for s10 transfer case. https://www.s10forum.com/forum/f30/p...l#post10995602

Might be some more useful information about getting a t56 and a transfer case to mesh.

Re: AWD Xtreme Build

I have a 2wd auto cab on my 5-speed ZR2 to fix damage from a rollover, the floors are different, but not enough to matter. Only difference is 2wds have a smaller hump over the catalytic converter on the passenger side but it still fits fine.


I also converted my 1992 4x4 to AWD using astro van parts, bravada parts are a better choice they use smaller pinion flanges, astro stuff comes in 2 sizes and the larger size hardly leaves a pinky width between the flange and transmission, and I had to put a jack under the floor and push it up to clear the front shaft. Its a 5 speed now, maybe some time I'll get a rear mounted t56 and use a camaro bell housing on the front and an adapter to mount a transfercase to the back.

I havenít seen a 4wd 5speed truck for sale in years.
