well a 6.2 , 6.5NA or 6.5TD should fit with the smallest effort, as
they were used in this generation of tahoe/burb/ pickup. you could
probably get a Cummins 12V B5.9 in there with a body lift and some
sawzall work. the 12V is a good choice as the wiring is incredibly
simple... two hot wires. the rest just take more time and cost more.
hell if you really wanted to, you could probably stuff a Cat C12 in
Do you happen to know if the blazer shares its platform with the suburban?
The weight difference between the 5.7 and any Diesel would be pretty great.
If its the same platform as the suburban, I would think the older Chevy
Diesel would bolt in with some nice massaging, Not to mention susspention
Now that I think about it. I remember seeing a blazer with a Diesel before,
I think it was an old Military Surplus. Ah yes! here we go. "6.2 diesel
blazer 1984 (M1009 Military Version)."
a little digging on www.google.com will bring up a bunch of stuff. just look
for "crate Diesel engine blazer" or just Diesel Blazer. They are out there.
its a short wheelbase so no on the suburban, maybe same platform as a
shortbox reg. cab. i wouldnt mind a cummings, good strong motors, to
bad there in dodges. would love to see gm get some in there trucks.
although the duramax is nice
That Cummins is a beast of a Diesel. Pretty much Bullet proof, Cant say the
same for most the transmissions that have been put behind them! The Duramax
is nice, but I prefer teh inline 6 configuration for pulling. I would LOVE
an inline-eight, but I dont have a four foot hood to work with.
the autos that chrysler sticks behind the cummins tend to live a
short life. we've got a '96 at work that is on the 3rd transmission
that *we* put in it (picked it up for a song from a subcontractor we
use alot) since 2000. if you're going to get a cummins, get the
Don't count too heavily on the Cummins 5.9. While it is an excellent motor,
it's heavy - and if you're in a half-ton truck you will need to beef up the
suspension to handle it. It was only available in 3/4-ton and larger
trucks. What you gain in simplicity in wiring, you lose in complexity in
the installation with all the body and suspension work, not to mention what
you will have to do for the tranny.
If you have the rounded-style body (as opposed to the older square-style, I
don't remember when Chevy changed the full-sized Blazers and Suburbans) then
the GM 6.5L turbo diesel was available in this body style in a half-ton
version (actually beginning in '93) so the installation would be much
easier. Unfortunately, the 6.5L is a drive-by-wire with no throttle cables
so you will need to replace the gas pedal and wiring harness as well as
switch over the ECM and other electronics. If you want to avoid the
electronics, you could bolt up an older mechanical fuel injection pump that
uses throttle cables to a newer 6.5L motor (which had an electronic FI
pump). Your other option is a 6.2 normally aspirated diesel which should
bolt right in with the least trouble, but it's going to be the weakest of
all the motors mentioned without serious mods.
There's nothing worse than getting half-way thru a major project like this
and continually finding out you need "one more piece" several times before
you finish. The only suggestion as to a gas-to-diesel conversion I can make
is find yourself a "donor truck" with the motor, etc. that you want that is
the same body configuration as your current truck, then just transplant
everything from the donor to your truck right down to the motor mounts and
gas tank and vice versa. At that point, sell the donor to recoup a few
bucks. It's the most straight-forward conversion process you will get. But
with a '92 you are going to have to start asking yourself which is easier
and worth your time and money - converting your current truck, or selling it
and buying a diesel version of that generation. Since GM diesels of that
generation didn't hold their value all that well, you just might do better
with a sell-and-buy.

Another reference readily available is eBay. Just insert the words
'blazer' and 'diesel' and you'll find various complete vehicles for
sale as well as engines and other components that show various years
the 6.2L was utilized.
The M1009 also goes by the military code of "CUCV".
The early 6.2 were actually built by Detroit Diesel. Around 84 Chevy took
over the assembly line. They changed the fuel filters and the rocker arm
assemblies. The 6.2 is a dog performance wise, but they get great gas
mileage. I had an 82 K1500, stick with overdrive that would get 28 on the
highway. Not bad for a 4X4. Had about as much power as a six cylinder. Only
problem I had with it was it broke a lifter and of course the fuel pump
died. Ford and Chevy had problems with the rubber damper used to cushion the
pump drive. Diesel fuel would eat it up and the bypass would stop up with
rubber. They came up with a better design on the damper later on.
thanks for the information. i love the body styles of this model
chevy, both the blazer and trucks. much more then the new body styles.
so it may be worth my wild to put some $$ into getting it the way I
