View Full Version : My S10 Blazer project (6.2L Diesel conversion)

I bought this 85 1/2 ton with a 6.2L Diesel drivetrain about a week ago.

with the intention of droping the drivetrain into my S10 Blazer

So far I've gotten the Diesel ready to yank, and will hopefully borrow the cherry picker this weekend for it.

Today I finally installed a body lift in my Blazer, to make room for the powerplant. (Sorry about the dirty rig)

I was a little dissapointed when I found out that the body lift kit didn't come with bumper re-locating brackets, but I'll figure out something.
I'm planing on getting my trailer hitch tucked right up to the body and will probably have it modified into the rear bumper.

My plans also include a SAS, and I might just use the full sized diff's in it.
The full sized came with a nice little off road package, including rear posi.
(Does anyone have a set of spring hangers that I could use on the front axle)

that'll be quite the project, make sure you post progress pics

thats awsome

Totally use the fullsize diffs man, widen that unit up. Diesel will probably snap your shit that you got now - it'll also lessen your issues with driveshafts and stuff. Spring hangers might be an issue like you said, but you could probably get some from a wrecker - bolt them onto your frame. you might need to relocate the pads on the axles. You PROBABLY have a corp10 front - passenger side diff - spring pad is right on the side of the diff and you can't move it in really. should be fun though - think about using coils, that might make it a little easier.

Keep us posted it would be a heel of sweet rig when done!!
Dont forget the pics!!!!!!

I couldn't borrow the cherry picker until now, so I took the full nose off to make the job of removing the engine easier.
It should be out tomorrow morning, and it's heading right into a friends shop to get the bearings all replaced and new gaskets / frost plugs.
I'm also getting the transmission shop to do their thing.

I will be using the full sized axles, along with a mostly Jeep suspension system and a friend of mine is giving me a posi unit for the front :D

The 85 full sized truck actually has a straight basicly rust free hood. Would anyone around Kelowna area like it. Good price, for free. Same as the T-case skid plate.

I'm taking some time off and doing the job in Midway. When I've got it on the road I'll be going back to Kelowna, or area

Edit, I just posted some pictures in Around the Bonfire that you guys might like. Just a warning they're all close up deer pictures not car related

have fun.. how bigs the body lift?

3" body lift. It took less than a 1/2 day as well.

The motors just about ready to go already. A friend of mine re-bearing'd it, although it turns out that it didn't really need it.
He also popped out the frost plugs, and ordered in new brass plugs.
The cooling passages were also clean.

The transmission shop will be called tomorrow and probably have it re-buillt by Thursday.

It looks like I might be busy until monday so I don't think that I'll get much done before then

The Next Stage!

Here's the Blazer now!
and here's what's going in next week sometime

The transmission was re-built and the motor has new bottom end bearings and brass frost plugs in. Along with the hard to reach gaskets replaced. (non were leaking and I want to keep it that way)
I'll hopefully have the motor painted before it goes in, but it's hard getting engine paint in a small town. I don't want to take the 2 hours out to go buy some (the parts store has forgotten to bring it out 4 days in a row now)

07-08-2006, 05:42 AM
Can't you rip down to grand forks to get engine paint...it's not that far from midway is it? But hey keep up the good work!

G-Forks is close. I just don't care to take the time out.

I'm going to Kelowna on Tuesday, so I'll pick up the paint there. It gives me a little time to clean up under the hood and figure out the wires and what not.

I am 1/2 thinking of changing the rad suport and switching to the newer first generation grill while I've got it apart. I guess that I should see what the wreckers have in clean parts available.

Just 1 update, I got the motor / transmission pulled today
I'm heading for Kelowna to look at another Blazer with a really nice SAS tomorrow, and will probably get some good ideas about the next big job.
Thanks Sean [cheers]

I really won't get much more done all week, other than clean up.
Although I will hopefully have the time to rip the front diff out of the parts truck and install the POSI.

You going to swap the hydro-boost too? Vac brakes don't work worth a shit with a diesel...

Also, are you keeping the AC in the S-dime? You might need all the room you can get. The 6.2 is about as big as a bbc.

Cool swap BTW, I can't wait to see how it all comes together!

I know about the Hydro Boost, however I really want to thank you for mentioning it.

I really want to keep the air conditioning. Something about a black rig in the hot Okanagan sun just doesn't turn me on. Although I do have a parts rig that I can rob the standard heater from if nessary.
I'll be pulling another unit apart and seeing if I can get a little more room.

The 6.2L is 4" longer than the 2.8L, and 6" wider. They are both the same heigth. So it'll be a tight fit all right.

07-10-2006, 09:32 PM
Yeah, it's a tight enough fit in a K5 engine bay...

Are you going to modify the firewall, or do you think it'll clear?

I hear you on the black truck thing...although i can just take the whole top off. :p

My next years plans include a roll cage, then chop 1/2 the top off, but it might not happen.

I've got a nice sledge hammer for the firewall, it'll be the first time that I'm intentionally going to beat the living hell out of a car. It'll look ugly but what the hay!

I think that the inner fenders will clear everything without mods

If I need a little extra room I'm moving the air conditioning rad under the bumper with a e-fan, and getting a rad made up that will fit where it was... with a remote filler neck. That'll gain me almost 3" right there

07-10-2006, 10:37 PM
I guess it's a bit of a trade off thing. You don't want to go too far back (driveline probs, firewall reconstruction...plus side is weight bias is better) but too far forward has it's own problems too. At 700+ lbs that 6.2 is going to be putting a fair bit of weight on the front diff...the farther forward the worse it'll be.

If it were my project I'd carve the firewall and push it back as far as possible and just deal with re-constructing/modifying the firewall. It's just sheet metal and there is no distributor to worry about. My 6.2 doesn't even have a vacuum pump back there...

A 50/50 weight bias is pretty much ideal IMO for climbing and stuff. The closer you can get to that the better it'll perform in almost any situation.

Thanks for the sugestion Rene, I'll look into it.
I'm not the best with the welder, but I do have friends, plus I can make fiberglass look factory

I don't mind lowering the motor an inch or so to clear the ar conditioning box if nessary as well.

If it wasn't for the heater controls I'd get rid of the vacuum pump as well... I wonder if I can just run a cable instead.

Do you by any chance live close to the Okanagan? I'd like to see your rig if possible some time.

Taxidermy, Nissan made a really good although underpowered Diesel engine. My mom has a 85 pickup that will have 600,000km on some time this week without any real problems.

Too bad that they haven't imported the diesel since 87 or so, although you can buy the Japanese imports now.

07-11-2006, 12:13 AM
Sorry, I'm down on the coast...or I'd prolly help you out. I'm a steel fabricator.

Don't forget that if you drop the motor down you are likely to run into oil pan to front diff clearance problems. Your 3" body lift will be a big help though.

Another alternative is to run a "vintage air" stand alone AC deal. Might not fit in the budget though, but it would free up some space under the hood.

I'm scrapping the independant front end, so I'll probably have another 4+" of clearance under the oil pan.

That's an idea about the vintage air. Thanks.

I'm busy all this week, but wouldn't mind running down to the coast next week some time if your around. It gives me a chance to pick up a set of used oil cooler lines (to see if the 4.3L's will work) and possibly go Sturgen fishing for a day with a friend.

07-11-2006, 08:20 PM
I wouldn't worry too much about the cooler lines. I got rid mine and plugged the block some 15,000km ago now.

FWIW, the 6.2L uses the same oil filter as any older SBC... so as far as filter-base-mount style cooler setups, you have some options.
