really only ONE diesel swap?

Postby biggreenoger [OP] » September 13th 2010, 12:57am

So as I have lurked around this site I have only seen one attempt at a diesel swap? Only 1 that has a drivable diesel Astro/Safari. With so many makers of these robust engines out there I'm a little surprised. I know room is limited but can't you just feel the tire burning torque, and great milage of 2.73 gears? Anyone toying with the idea? think of the possibilities... :whistle:

i think about it regularly but I'm unsure of any available Duramax that will be able to fit in the Vortec's place. I know if and when Chevy wises up and releases the 4.5L Duramax I'll be one of the first in line at the dealership to buy the motor, allison tranny, ecm, tcm and a eaton posi. But until then I'll stick with the 4.3

Oh ya the D-max, Great engine and very capable of impressive numbers all the way. From fuel mileage to power it really stands out. With dimensions and weight just ever so greater than a big block chevy it could work. But as for price well, bet you could get a small block to run on water for less. Hows about a UD trucks 4.2L I-6 banger( Nissan I think), Isuzu's( maker of the D-max) 3.0L 4J or the 5.2L 4H. These are fairly comparable t the size of a v-8.

The Isuzu D-Max 3.0 L has less power and torque than the 4.3 so it's not worth the cost to get one. As for the Nissan... I wont touch/own/drive anything that doesn't have a bowtie on it and I certainly wont taint a Chevy with some foreign engine.

In 1991, the limited-edition GMC Syclone featured a 280 hp and 350 lb·ft turbocharged and intercooled LB4 with the first use of multi-point fuel injection on a 4.3L Vortec V6. Power output of the new LU3/LG3 engines is 180 hp to 200 hp and 245 lb·ft to 260 lb·ft.
Now this is a newer engine, so I agree its spendy$$$$$$$$
4JJ1-TC produce 150 horsepower and 282 lbs.-ft. of torque. Despite its spirited performance, this engine is a miser. In fact, the NPR ECO-MAX achieves up to 20% better fuel economy. Like every Isuzu powerplant, the 4JJ1-TC is a true commercial vehicle engine. Each component has been crafted to reduce maintenance and increase durability.
So it’s no surprise that the 4JJ1-TC can be driven up to 10,000 miles between oil changes and has a class-leading B10 durability rating of 310,000 miles—meaning that 90% of 4JJ1-TC engines will reach that mileage before requiring an overhaul.
Torque is what gets you moveing.

I think a fresh 6.2L would be a bolt-in affair.
Back in "the day", you could get nearly 30 mpg in a 6.2L 2wd Suburban. Not sure if there is room for boost, but it would be an interesting setup for sure. :)
Best MPG to date:
21.0

The only Mopar engine I would ever drop in a Chevy is the 528 hemi.

If I had to choose between a Cummins or the new D-max I would go with the new D-max because I like the numbers better.

@ donkey: the 6.5 turbo charged V8 diesel will fit just as well.

:naughty: Cummins is not a Dodge engine, but maybe the only reason to own one. It is an Industrial engine the has a proven back ground, and is found in almost every make from Chevy, Ford, Dodge to International. Mine tho did come out of a Ram 2500 :oops: It will loose the Dodge rocker cover too.
Well the 6.2, and 6.5 are a real clear choice as for drop in bolt up and go. The 6.2 (especially the 1982 the stongest block) are still plentifull as the US Military ran them in almost all GM light trucks and hmmvees and still have hundreds in crates. Humm a twin turbo 6.2 and a built 700r...I know a guy that has a retired 1009 K5 blazer on 37" humvee tires and he claims 30+mpg. The 6.5 is based on all most the same block so it should fit nicely also. I think I saw a build that someone started with an Astro getting a 6.2. I try to dig it up. The Duramax is very impressive all the way down to all of it elctronics. To play D-max one would need DEEP pokets.

This was all I could find on that 6.2 swap. I'm thinking its a Th400 on the back side, but deff a astro frame section. The last time he posted anything was in '07 but nothing after these pics.

Just for the record-not the only diesel swap.

viewtopic.php?f=68&t=6981

It's listed right at the bottom of your thread in similar topics.

Also-about a year ago a guy posted he worked for a company in South America who bought second hand new builds diesel Astro's that GM sub'ed to Japan to build.They have a fleet of them with the original window stickers that included the extra charges for the diesels.BTW-that post is not on this site.

The early "want-to-be' Olds diesels where pcs of junk.I owned one and the one thing they are noted for is cracked heads and blown head gaskets.Heavy walled blocks that had a wt unwarranted for their intended use with junk heads,head gaskets, and a valve train I wouldn't want to wish on my worse enemy. :banghead:

Should you be proud of your build??I am saying you bet.Well done.The first and only one????.Doesn't seem so........ just for the record.

Oh no, I would not say mine is a is a sucessful swap since i used a full size blazer 4x4 frame. But some where i found a guy who had a Iveco 3.9 diesel in his astro and had road worthy miles on it. My van is just one of those "I had an itch in need of a scratch" cuz I can things. But I'll have to look those other JDM vans up for the specs on them.
EDIT: Ya thats the one that i was talking about.....Iveco 3.9 liter turbo diesel. (same size as Cummins)

i know gm use to put the 6.5 or the 6.2 into many half tons of the 80s' and i was a proud hand-me-down owner of an 82 cutlas diesel. though none of these were ever turbo. i found them all to be lacking in power. installing a new turbo diesel would pose alot of driveline issues and i havn't seen any diesels in less than 3/4 ton. so i would say that a diesel swap would cost alot more because to get reliability, you would want to change the whole driveline. not saying you shouldn't entertain just the engine/tranny.

:lol: :lol: seems the censors cut my comment......well what's a old hot rodder to do........ :doh: :doh:


I have 4:11 gears front and rear. The front axle is a dana 60 hi-pinon out of a '78 f-350 camper special the rear is a dana 70HD out of a '79 chevy 1.25 ton. it sits right now on 38's but i have plans for large 35" drag slicks to show off with. Np 205 iron transfer case to connect the diffs. Waiting for the trans to come back from the builder, and then off to get some drivshafts..

i know gm use to put the 6.5 or the 6.2 into many half tons of the 80s' and i was a proud hand-me-down owner of an 82 cutlas diesel. though none of these were ever turbo. i found them all to be lacking in power. installing a new turbo diesel would pose alot of driveline issues and i havn't seen any diesels in less than 3/4 ton. so i would say that a diesel swap would cost alot more because to get reliability, you would want to change the whole driveline. not saying you shouldn't entertain just the engine/tranny.

The Military ran the 6.2 in all GM light trucks and even the humvee all the way till 1990 i think. After that the humvee got the 6.5td and now they have the D-max. I agree that the first gm diesel are best used for anchors, but the '82 and up take to a turbo like a pig to mud. I once had the ill fated ownership of a '80 heavy half with a diesel that could bearly pull its self. But I do have a buddy ownes a retired 1987 military 1009 blazer with the 6.2 and 37" humvee tires still NA but turned the fuel up and loves that truck. And that pile gets almost 30MPGs.

How about this: it a damn Mopar engine! :rofl: :rofl:
The only Mopar engine I would ever drop in a Chevy is the 528 hemi.

If I had to choose between a Cummins or the new D-max I would go with the new D-max because I like the numbers better.

@ donkey: the 6.5 turbo charged V8 diesel will fit just as well.


:naughty: Cummins is not a Dodge engine, but maybe the only reason to own one. It is an Industrial engine the has a proven back ground, and is found in almost every make from Chevy, Ford, Dodge to International. Mine tho did come out of a Ram 2500 :oops: It will loose the Dodge rocker cover too.
Well the 6.2, and 6.5 are a real clear choice as for drop in bolt up and go. The 6.2 (especially the 1982 the stongest block) are still plentifull as the US Military ran them in almost all GM light trucks and hmmvees and still have hundreds in crates. Humm a twin turbo 6.2 and a built 700r...I know a guy that has a retired 1009 K5 blazer on 37" humvee tires and he claims 30+mpg. The 6.5 is based on all most the same block so it should fit nicely also. I think I saw a build that someone started with an Astro getting a 6.2. I try to dig it up. The Duramax is very impressive all the way down to all of it elctronics. To play D-max one would need DEEP pokets.



Deep pockets for sure.
I happened to look at the price of a brand new GMC 1 ton duramax Pickup, and it was nearly 80 grand, before tax and dealer BS.
I didnt bother to look at the new Vette's pricetag as it just seemed to depressing, sigh.....
