I was considering installing a 4bt in a late 80's or early 90's S-10. I was thinking I could get 30+ MPG out of it, but Iam not sure the truck could handle it? Has anybody done this?

Because of the weight, and height of this engine, it might be a little much for a S-10. I am sure it could be done, but your truck might not be to happy about it.

from another thread..sound perfect for a S10

"I think the Cummins B 3.3 Turbo is an ideal eninge to swap into smaller things. Like jeeps and things of that size. Its mechanically controlled for easy installation. Just a suggestion."

I have been thinking of repowering a 95 AWD Chevy Astro van with a 4BT, but was having the same concerns as HANK1948 about weight and torque.
Currently the van has a 4” lift from Overlandvans.com

The front consists of 2”of body lift and 2” from reindexed torsion keys. The clearance measurements on the diesel page at Overland seem right but the 4BT specs are different than Cummins own. I am interested in the B3.3 and was wondering if 120hp/~320f# is possible.

From an S10 fan

I had every intention of installing a 4BT in my 4x4 S10 but it ended up falling through for a number of reasons:

1. Clearance, we were going to have to either do a body lift and install the engine drivetrain high ( ugh) or drop the level of the front "chunk" or swap the front IFS for a SFA any one of these options really takes away from making a reliable dialy driver with as few custom parts as possible.

2. weight, the front end would have to have been beefed beyond a reasonable level to carry that engine. again not pract for a daily driver.

3. torque, dana 44 is an aweful week axle to put that kind of torque thru. Options were to go to full ton axles but then they had to be shortened... More custom stuff.

Custom stuff on this swap would send the price out of the atmosphere.

Flyin71H off the yahoo club put together a full size 1/2 ton chevy with a 5 spd and has a load of miles on it, really thinking about copying him in what he did.

I believe he was talking about low 30's or really high 20s
