Well after much debating, i'm going with a 4.3 with a 700r4 in my yota, sure you never heard of that. However i have been reading many forums, some guys are running yota t/c, others running NP 205s. My question is what about a NP 208, who's running one? Much lower gear than the 205. My truck is an 87 4 runner, that see's double duty as a camping/ mild offroading with the family. Just trying to keep from spending 700 plus on an adapter for the yota t/c.

Thanks, Doug

 

I want to. Can't seem to find one in the pick and pulls around here. I have the np203 in my ext. cab. It sucks....

I've read that gm offered a right hand drop of the np242 "I think" It was in some blazers and sub.'s Haven't seen one of those either.

 

So you are running a chevy trans and transfer case, did you have to do any mods to the floor pan. I'm just wondering about clearence issuses.

 

3" body lift.

 

I have a V8, 700R4, and NP208 in my 93 Toyota. No body lift, custom cross member. The floor / firewall needed just a little clearancing with a hammer since the 700R4 is much wider than the Toyota transmission. No TC shifter yet. It's on the to-do list. I'll probably graft a shifter from a Blazer onto the Toyota floor whenever I can find one.

The transfer case hangs really low in my setup. I was determined to not have a body lift, and I'm paying for it now since even the transmission pan hangs below the frame rails. It would need some serious skid plates for any rock use.

The 208 isn't the strongest around, but GM put it in Suburbans so it can't be that bad. And it's very light compared to a 205 or 203. I'm confident that something else will break long before the 208.

Later year solid axle Blazers/Jimmys (~1990) came with a NP241 with a passenger side front output. Earlier models has a 208, and later ones were IFS with a drivers side 241.

 

RevNL, thanks for the reply. I was wanting to do this without doing a body lift as my truck went up 5" with the SAS. So how much body lift do you think you would need to get the trans flush with the frame rails? I would like to keep to a minimum.

 

On mine, the bottom of the pan is about 2" below the frame rails. Not too big a deal. Any decent skid plate should take care of it.

The transfer case sticks down around 8" below the frame rails.

I was kind of shocked when I finally had everything in there and stepped back to take a look. It basically negates all the lift I've done to the truck.

Another point of concern is the radiator. All the aftermarket options and all of the cooling systems I've read about here depend on 2" or 3" of extra space between the hood and the frame rails.

 

Well that was what i was needing to know, as far as the radiator, i found a aluminum one at a Street rod shop for $109. My father has one of these in a 47 chevy sedan with a 427 big block, and it runs around 200 on the hottest of days, and it only 24" wide. I think the yota rad is 22 x 19, and they have one 22 x 19, so i think i can make it work.

Thanks, Doug

 

Are you guys running a fixed yoke, of did you stay with the slip?

Thanks Doug

 

Slip yoke for me.

Here's a thread on clocking and adding a slip yoke eliminator to a NP208:

I wish I'd done that before I fabbed my crossmember.

 

Thanks for the link, so with out a body lift would you be able to clock the transfer case up?

Thanks, Doug

 

It looks like it. Depends on what options the clocking ring offers. The bracket that held the IFS torsion bar will probably have to come off.

 

I have an 83 yota pickup with a 350 and I am running a 208. I put a 4" body lift on mine so I would have plenty of clearance and it is the perfect size body lift for me. It also allowed plenty of room for my radiator. But when it comes to strength, the 208's are pretty damn strong they just don't like great impacts. I have seen more than one with a broken off tail housing. But as long as you aint wheel hoppin, you should be good.

 

I did this conversion I have a 2 inch body lift sas conversion running stock v6 radiator work great. still running slip yoke in 208 have dana 60 rear and dana 44 front I love it hasnt broke yet

 

Im running the 4.3 700r4 and 208 case and love it the low gear of the 700 and the 208 are great offroad around here.I dont have to use the breaks as much as some of my friends i used a 3.0 radiator that came in my runner I ended up having to install a 4in lift due to the fact that I didnt have the cash to do a sas right yet.I am running a 98 4.3 out of a 4x4 blazer it has plenty of power for such a heavy vehicle and just keeps getting heavier.

 

Revnl, do you have a build thread? Sounds like you got a pretty sweet ride!
