Been thinking of this one. The "new" older luv than my first is starting to smoke... heck, could be used as a mosquito fogger for those that think of trying it lol... the g180 has had it's day. Confusing part is that it has good compression across all 4. But that's subject matter for another area of the forum. Back on topic:

I see a lot of v8 swaps and plans here to do so. I prefer diesel engines and know if you can fit a 305,350 or any other sbc into something a 6.2 can fit as well, as they're only about 50 lbs heavier fully dressed and can use the same motor mounts in most applications... so why not in a luv? I mean, it'd be v8 power (kind of) and a diesel to boot... anyone heard of this being done? I wonder if it would be truly feasible as an option for mine?

I worked for the State of Ca and we had hundreds of 6.2 & 6.5 engines. My thoughts on them, "I would use one as a boat anchor but it would fail as that too".

The 6.2 is underpowered but if taken care of as reliable as anything (except a cummins) IMHO. The idea of similar dimensions to a SBC and the fact it is low-powered compared to the other makes is what drove me to think of it running in front of stock or mildly upgraded luv drivetrain components... I'm going to scour around and see what I can find just to get the feel of the idea.

BTW, my burb had almost 400k when I finally sold it, with only a tiny drip from the i.p... only ever replaced a starter and 4 glow plugs the entire time I owned it (minus maintenance and filters etc). I guess it's one of those things only a nutjob could love... (like couriers and datsuns lol)...

My buddy was given an '82 GMC Dually with a 6.2 in it. He gave it back. :lol: No really, he added the Banks turbo kit and it helped some. Next, he was told to install 6.5 injectors and pump. That is supposed to really liven it up.
He says he thinks it has a sensor on the hitch ball. Whenever you put ANY kind of trailer on it, the power is cut in half. :lol:

But in a LUV would it matter?

In it's day the 6.2 was a great engine. It wasn't a race car engine, but it returned great fuel mileage and would outlast the body. Top speed in my moms 4wd Suburban was 80 up a hill or off a cliff. Thing ran forever. We sold it with 400K on it and last we saw it the engine had outlasted the body.

People talk bad about them because in comparison to modern engines they are anemic. The same way that a 1969 427 Camaro is anemic compared to a 2011 Nissan Skyline. But it is an apples and oranges comparison.
I think it would be an awesome swap into a LUV.

I think it depends on what you want to build to? 6.2 for mpg or the 6.5 for more power and a little better engine.

after you get done spending the money on the turbo for the 6.2 you might as well did the 6.5 is already got the turbo and 6.5s can put out some power.

My friend swapped a 6.2 into his 86 chevy 1/2 with a 6in lift and 35's same motor mounts. He spent 600 bucks for a garret turbo kit? its not banks. But its only 15 pounds of boost. Its rather a joke. for 600 bucks. he wishes he did a 383 stroker but the 6.2 gets 16-18 mpgs with that big lift and the big tires.

Just food for thought :lol:

(P.S. A 4bt cummins will fit with a body lift. 8) )

No, I am talking bad about them because we replaced heads on them too often and a ton of injection pumps. It was so bad we threatened GM with a lawsuit, we got dozens of free trucks. All we asked of the 6.2 was to haul as per the owners manual, it will but you can bet the heads will crack. I have changed over 15 sets myself.

Aside from an actual Isuzu diesel wouldn't this diesel be the most sense in a swap? For the motor mounts and general wealth of technology on swapping SBCs into LUVs like he said. I am going to put a v8 in my truck someday, (long time from now no doubt since my 1.8 is OK), diesel / Biodiesel would be a neat trick.

I will look some more but maybe answer here too, best diesel to swap in?

Why exclude actual Isuzu diesels? There are some great ones if you look at the ones sold on the Japanese Domestic Market ("JDM") that can be imported here.

is the 3.1 isuzu trooper v6 turbodiesel worth its weight? i have seen a few from time to time on ebay and they seem like they would be a reasonably easy swap for weight/power

Huh ive never seen those before! I wonder what there weight is? and I think JoeIsuzu is right. Why not a Isuzu 4BD1T? there very great diesels, you can buy loads of adapter kits to bolt them to a lot of different things! there way cheaper than the cummins kits are! But they weigh about the same of the 4bt cummins though. Weight will always be the problem in a diesel swap. (i mean the 4bt and the 4BD1Ts)

a 4bd1-t should still be a feather compared to a 6.2 or a 6.5 8O a brick vs feather compared to the g180 but still reasonable :lol:

6.2 chev 855lb
4bd1-t isuzu 785lb
4bt cummins 782lb
so your looking at a difference of about 70lb over the v8 and 3 more than 4bt :lol: .. so not that much of a "feather" but still a reasonable difference.

I guess I meant 'other than' because that's an obvious choice, and maybe I was thinking about more turbo/trans options. Sounds like the GM diesels I mentioned might be a boat anchor. Didn't realize diesels were so heavy anyways. Thanks!

The 5.7 diesel would be a better choice and yeah i know about the first year and other problems but they can be overcome with little work heck there was even an 4.3 diesel.

the 4DB1-T or 4DB2-T is about 750lbs with no trans and are common to have a 2,800ish top rpm limit, its more or less the same size as the 3.9L Cummings engine.

the JDM 4JB1-T or 4JG2-T are about 700lbs with 4wd trans. being that there out of troopers, rodeos, ECT in Japan they have a max rpm of 4,200 but burn way less fuel at about 2,600
that's what ive found with my 2.2L diesel any way......

how that compares to the 4.3L 5.7L 6.2L 6.5L GM diesels in LBs i have not a clue.....


when you compare a V-8 with auto trans, to a 4JB1-T and manual trans. that's a fairly sizable amount of LBs
but when the V-8 has a manual trans its not quite as big..


(edit)
the 2.2L engines are about 450lbs with no trans.

The 6.2 6.5 have weak harmonic balancers too. They have only a cast iron crank, so it is a good thing to replace it. Check the chevy diesel forum and you will get the skinny on them to. Luver8 is right, I think but I. Don't have any experience with them. They came out after I left GM dealers. The 4bt has a lot of the turbo piping that go's over the top of the valve cover. All I have worked on were that way. There is supposed to be some with piping that does not go over the top. I have not seen one. You can go to the 4th swap forum forum to get more info on them.

You could use the 1.9 turbo engine from VW. Already tranny adapters to use a Toyota automatic and manual transmission from Sami 4x4 supplier. Good engine, I had one in a VW passat. Only thing you need to do is change the timing belt around 60k. New belts will go longer.

The olds 5.7 diesel will fit, but it has it's own set of problems. I got 400 k on one but you need the right stuff. Pistons are almost impossible to find for them.

Also some Isuzu 4cyl diesels that are a good choice as a 4bt. Check the 4bt swap forum on them too. Medium duty truck engines.
