@higrafey Black smoke can occur across the entire operating range, but is usually worst under full power, or during the lag before the turbocharger boosts air supply to match the fuel usage such as in the early stages of acceleration and during gear changes. Moderate turbo lag smoke is acceptable; otherwise black smoke should be hardly visible in a correctly running engine.So other words BLACK SMOKE :) badass jeep though im looking to put a 4bt in a xj
@greatplanesman The engine puts out 135 hp @ 2800 rpm and 265 ft-lb @ 2000 rpm. This project is still underway, so I don't have mpg numbers yet. I'm expecting low 20s.
@XyenkocamaroX There's more to engine selection than rated output. The torque curve is more important than horsepower, in this case. And besides, not everyone wants or needs a 500 hp monster engine, especially in a short-wheelbase Jeep.
@speedfreak460 It's like swapping anything else into a Jeep, but you need to make some custom parts (motor mounts, crossmembers, frame reinforcements). The toughest part was finding an engine adapter so I could use a standard GM transmission.
@speedfreak460 Everyone uses a 4BT, and I wanted to try something different. The Isuzu engine is quieter, smoother, and produces the same amount of power. I'd recommend buying a donor truck instead of just the motor -- an old NPR can be had for around $2000-$4000 depending on condition.
@higrafey Chrysler are idiots for restricting diesel-powered Jeeps to Europe. Nice work, and I "get it" as I'm currently swapping out a Westerbeke W-52 (actually the Mazda S2 2.2L diesel found in old B2200s and Ford Rangers from the '80s) with a new Beta Marine 60 (a Kubota 2.4L) in my steel sailboat.
So there's a lot of measuring and fabrication in my near future.
@svalchemy Ah yes, I know all about measuring and fabrication. At least mine doesn't have to float. :-) Good luck on your sailboat. Sounds like a cool project.
Amen to that! I would love to walk into a dealership and get a brand new diesel Jeep complete with a warranty instead of having to do it independently. Too bad Chrysler killed it. I think there's a reason Fiat owns them now.
@Yardjass I don't actually own a car because I live closely to my two sailboats, one with a workhorse 30 HP inboard gas engine designed in WWII called an "Atomic 4", and the other with a new diesel I'm prepping to install.
If a biggish car company made something like a Ford Transit or a Nissan Cube or a Honda Element with the little 40 HP diese that came in the first gen Mercedes Smart Car, with a hybrid option for lithium ion batteries and regenerative braking to charge them, I would buy it!
Haha, that would be aawesome even with just a small diesel and not all of those hybrid components. Doesn't the smart car get like 85 mpg with that engine? I'm waiting for that 24/36 mpg wrangler that they already have out in Europe. Either that or a diesel Fiesta or something similar sized. I'll probably be waiting a long time though...
Yeah, I remember those. I'm really partial to the wrangler though. I just bought a Golf TDI but I'd trade it in a heartbeat if they brought the diesel wrangler from Europe over here.
BTW What you got there is a classic. I had an 87, it was rigged as a rock crawler, full roll cage, skids, engine, 60 dana's, lockers, rockers, gears, etc..I bought it for 500 bucks from an old boatyard. Sold it for 15,000. It was built and never used. It sat for 5 yrs. Only thing was the floor boards thanks to it having no cover but still a little elbow grease and it paid off. Jeeps are so much fun and the Manufacturer should put a diesel in and coils springs out
@Sunfadedlovejaded The engine and Jeep will likely be the same color, a flat desert tan. Industrial style. Sounds like you had a pretty cool Jeep there. I agree that they ought to make a diesel available to the U.S. market. It's doubtful that will happen, since most everyone would rather drive a hybrid or an electric car.
@rockinbass01 I already addressed the transmission questions in an earlier comment, so please check there for answers. The wiring isn't set up yet, but it should be easy to separate the YJ body wiring from the engine's wiring -- this is a fairly uncomplicated engine, especially if you bypass the glow plug controller and wire them up manually.
@DEXH2K chevrolet luv was a rebadged isuzu, not a gm vehicule. It's after the luv that gm saw the potential of small pickup and built the s10. I'd love to have one of those small isuzu pickup with a 2.2 diesel
@tpvalley My 3.9L is rated at 130 hp and 255 lb-ft at 2800 rpm. I think you might be referring to the non-turbo 4BD1 that was used back in the 1980s. The torque comes on at about 800 rpm and stays nearly flat. This engine has 225k on the clock and it runs like a top, aside from a bit of blow-by.
@walkingfreak Yes, GM and Isuzu co-developed the Duramax engines used in today's GM trucks. The engine in my YJ, from a GMC/Isuzu box truck, isn't considered a Duramax... but it's still a GM/Isuzu engine.
@luciusthegod I'm running an SM465/NP205 combo from a late-'70s GM truck. I began machining my own transmission adapter, but those plans changed when I came across an industrial Isuzu 4BD adapter. It converts the bellhousing to a truck-style GM Saginaw transmission bolt pattern.
@greenmountainsolar By fan plenum, I guess you mean the fan shroud? I'm going to install an electric fan when the Jeep is finished, so there won't be a conventional shroud. The clutch-driven fan was for testing purposes.
yeah..the shroud... you know, for simplicities sake, the plenum combined with a 'flex fan' would really crank a lot of air through the radiator at low speed 4 wheeling... they are fairly cheap and simple to install. just a thought.
@greenmountainsolar Thanks for the advice. I was leaning towards an electric fan for the sake of clearance; I need to move the engine forward a few inches to improve my rear driveline angles.
wow..the torque was moving the jeep... you better have a light foot or a strong drivetrain... i really want a diesel engine in my wrangler... nice work..!

Isuzu rules in diesel technology...
It provide engine to GM since 1970, for example Chevrolet LUV, many trucks, and other vehicles....
Duramax motor was development by Isuzu, you can visit the Isuzu company and you see that i'm talking about.
Isuzu is the most big manufactured from diesel motor, and provide engine for many others things like boats, etc...
