Nothing beats a cummins, Oh!.... except maybe a Cat.Not all of them. The 2.8HS is nice, but timing belts, aluminum cylinder head and a history for broken pistons, spun bearings and general shoddy performance has me less than sold. Not to mention a very questionable legality VS EPA / EC regulations. I would stick to a federally certified EPA engine.
I would stick to industrial duty instead of automotive duty.
I called the guys down at the engine program (or whatever its called) but when you do an engine conversion, and need it inspected for emissions for the city of Denver, you take it to them to have it ok`d.Does anybody know the Emission laws for Denver on this conversion?
I was wanting to put the 4bt cummins in my 1990 toy truck.
Long time lurker on mud, first time contributor though. The green 80 is mine. Picked it up from Proffitt's on the 12th and drove it back to the SF Bay Area. The work is beautiful, everything fits very nicely and the truck runs great. The two trucks averaged around 22mpg on the way back, but we were not gentle on them, cruising at 80-85 mph on the way home over all the passes and everything. Tinkering with the fuel screw and the pump timing has provided a nice bump in power. New injectors will be on order soon and then a second tank to run svo.
As for the abs, the truck is now part time 4 wheel drive, so the abs only works when the front drive plates are locked. Not a big deal in my opinion, but the ABS warning light is on which is a little annoying.
Thanks to all the guys out at Proffitts that put this together for me.

I can't believe nobody has asked but, How much does it cost to do this to your rig? Also what do you have to provide (the drive train)?
I saw the quote of 12K -13K , Is that for "turn key" or are there any other cost?
It has been asked and has been answered. Conversions usually cost between $12K-$14K. That is a turn-key conversion. You drive in as a gasser, and you leave as a diesel. You don't supply anything, unless you really want to. Sometimes the customer can find a 4BT cheaper than we can. Engine prices are going up as EVERYONE wants a 4BT now. You can hardly find them for less than $3K anymore. They are being put into everything that you can imagine.........Land Cruisers, Broncos, Scouts, Jeeps, Power Wagons, etc.
I feel that the 6BT is way too much engine for a Cruiser. Yes, you can put one in and it has been done before, but I would not want one.Thanks HZJ60 that was my next question. It seems that you can find the 6bt a little more easily, and maybe a little cheaper as well. Man that thing must be a heavy beast though.
From all the research I (and many others here) have done I was told that you could not do this conversion and have it smog legal in CA (I know diesels are smog exempt that is not the issue). Is there a loop hole I am missing somewhere? Any insight would be much appreciated!
Dre... http://www.isuzudieselswapper.com exists. You typed "swappers", not "swapper".

it is not a problem. the CARB rules state that the motor must be from a vehicle the same year or newer than yours, and it must have all of the emissions that it came with. CARB does not address diesels specificly as i recall, but the rules are posted on line if you want to check it out.
Thanks. The way I understood it was that it is also a weight class issue. A guy I talked to on the phone at CARB said that you can't put a medium duty engine in a light duty vehicle as well. Which technically according to him would be a 4BT into a Cruiser...
well.... technicly a medium duty truck (even though they say "heavy duty") would be something like a dodge 2500/3500 or a ford f250/350. heavy duty trucks would be like the topkick or similar. so really he is not correct. besides, the bread trucks they put those motors in, are certainly not heavy duty.
