I really wish we had more info that 4bt looks like it was factory installed. My original intent was a Cherokee with an OM617,but last night started thinking on an Explorer Sport 4BTA and now I find this...must be fate.
Now I just have to sit down and plan my truck on paper. Driveline options modifications etc.
Thanks for the inspiration,
If I did an explorer it would be one of the newer IFS ones (95-98) and I think a body lift would be necessary unfortunately. I'm torn between explorers and broncos. Explorers will probably get the best mileage though because of the smaller area and less weight.
I'll work on the pictures when the tornadoes blow out of my area. It was originally 4wd and we ran it that way for a long time. We changed the transmission about 6 months ago and went 2wd because we never really used the 4wd. Both 4wd and 2wd transmissions were T5's out of a chevy. We used the original factory AC and Power Steering. All brackets were homemade. Also, it uses an alternator that originally came in a chevy luv because that particular alternator has a vacuum pump on the backside. the turbo housing is orginal (Frito Lay Step Van), though the insides were swapped out of a turbo off of a Komatsu 4B. That helps produce boost at lower rpm. I get good power and boost starting at about 1500 rpm. We used the original 8.8" rear end, but I swapped the gears from 3.27's to 2.73's out of a mustang. Seems to be ideal gearing for this vehicle. I get 32 mpg and am only running about 1850 rpm at 70 mi/hr. Most everything else is original explorer. With the original fuel tank, but all the stuff taken out of it, it holds about 24 gallons, so I can comfortably go over 600 miles between fill ups.
Thanks for the interest. I'll answer as many questions as I can. My plans for this summer are to remove the engine from the explorer and install it in an '01 quadcab Dakota.
tdart- I'm curious how much clearance there is between the AC evaporator and exhaust manifold on your explorer. And what about between the back of the engine and the firewall? I'm working on a 93 ranger swap and would really like to keep my stock AC system. I was kinda worried about clearance issues, but hey it looks like it can be done!!
I've got a foot between the evaporator and the exhaust manifold. The last valve cover is about (hard to measure) 3 inches in front of the firewall. I hope your ranger swap goes well. My father in law has gotten good service out of his. It tows great and has gotten nearly 40 mpg before.
Wow. A foot? The V6 manifold in my truck now only clears the evaporator box thing by a few inches. That's gonna be great I guess. And the kinda mileage you guys are getting? I was only planning on ~ 25 or so max.
I'm assembling my 4bt right now. School is out for the summer in a week, so in a week or two I'm gonna be starting a build thread on this site.
