what was the crappy diesel that chevy used in the 90's?

6.5?

i heard the 6.2 detroit diesels put in the military trucks were fairly nice!

were they turbo'd? i know nothing about them LOL

 

its gonna be a daily driver for awhile. im running 35s right now.

so 60% dd and 40% off road fun

the vw would be nice. and could probably pick one up for cheaper and easier to find then the merc

 

Yep, the GM 6.2 6.5's are pretty much the bottom of the barrel...

The reason the military doesn't have any issues with them is b/c they've got an all expense paid parts and labor work force to maintain them...

They are terrible...

"Common Problems

Main Bearing Web Crack: In both 6.2L and 6.5L engines this is reportedly fixed with a combination of improved higher nickel cast iron alloy and lower block re-design including, but not limited to, a main bearing girdle. These features are in the new for 2007 AM General GEP P400 6500 Optimizer enhanced 6.5L diesel presently being sold to the US Government for the 6 ton armored HMMWV.[1]
Crank Failure: Related to age failures of the harmonic balancer, the vibration damped accessory drive pulley, or the dual mass flywheel.
Pump Mounted Driver: Relates to thermal failures. The PMD is screwed to the DS-4 injection pump on the 1994-2001 GM 6.5 diesel utilizing fuel flow to dissipate heat. The injection pump is mounted in the intake valley (a high heat area). The PMD contains two power transistors that should be cooled by proper contact with the injection pump body. If the pump is not precisely machined to make complete contact with the transistors via the silicone thermal gasket and paste, the PMD is improperly installed without the gasket or paste, the PMD is installed off center with the pump body, or corrosion develops on the mounting surface the PMD will overheat. Several companies manufacture an extension harness and heat-sink kits. These allow an owner or their mechanic to relocate the PMD away from the injection pump to a lower heat environment and/or a place that can get more air flow."


BUT, they were made in numbers. So at least you can find one...

Which is good, case you'll need the parts supply.

Banks has a GREAT turbo kit for them.

 

Banks has a KICK BUTT twin turbo kit for em...i believe it's twin turbo..been a while since i've checked out Banks

i'll be the first to say..German's designed the TDI GREAT!!!! but their wiring.....it leaves a little to be desired.

we bought a VW jetta TDI with the 1.9 in it...and it was great...for the most part...problems with the glow plugs..and a couple other various wiring problems...then something messed up on the inside..and we had to rebuild it.

got everything put back together..and it's a lot louder than it used to be?

sold it to a guy for $2200 i believe? with like 270,000 miles on it..but only a few on the rebuilt motor.

it ran great though! pulled some decent hills very nicely!!

 

ya im a mechanic in the army and both the 6.2 which is non turbo and the 6.5 which is are POS the break alot not enough power just all around not good motors

 

A friend of mine did a big OM617 project here:
http://www.expeditionportal.com/foru...ad.php?t=20372

Is still working on it actually.

 

that thing sounds amazing...

you've got me rethinking my original plan of a high HP V8 swap for my next project... thanks

 

Diesel is where it's at...

the VW 1.9 might even find it's way into my 4Runner one day..........if a company ever decides to make a conversion harness

 

Before you go diesel, make sure you know what you're getting into. Most likely, you won't be able to fit that Ford engine in and you'll end up with a Merc or VW motor. If you want V8 power, get a V8. Most likely, your diesel conversation will be relatively slow accelerating. Where diesel shines is low end torque. With my 22RE/5spd/stock gearing, I very often stalled out on steep tricky sections of trail. With my diesel Landcruiser, I can idle down to about 300rpm for short times and have yet to stall the motor in low range on anything, even with riding the brakes up hill. Diesel is THE motor for offroad... why gasoline ever made it into anything with 4wd beats the hell out of me honestly. Your gas mileage will be better- my 5700lbs cruiser with a boat on the roof gets ~18mpg city and highway.

 

I'm dreaming up a OM617/A340f with flappy paddles in my 94 4Runner with something like a 3" body & drivetrain lift, or a BJ spacer/FJ80 coils lift maybe with a 1" BL for good measure all topped off with 33/10.50x15's and selectables...

I'd go 5speed if the OD rpm drops weren't so low...


Shouldn't have to re-gear... Should be @ 18-19 mpg and still get up with fast traffic...

I can dream though...

 

see, a stock diesel is for the low end torque....in TRUCKS.

diesel car motors are designed a little different...they produce power for longer periods of RPMs.

you could floor the Jetta we had and it would just keep going..through whatever RPMS you wanted to take it...it would just keep pushing!

our dodge diesel however..it kinda "cut off" at around 3700rpms...

of course by that time you're in the "red" of a Dodge Cummins lol.

wouldn't need to run that high of rpms anytime anyway..(in the dodge).

i think a VW TDI swap, with a flashed ECU. 4.88's and 36's would be a great combination

 

WOW!!! My new favorite truck ever!

 

toyota sells a diesel overseas in it's Hilux that would be alot easier

 

as much as i like the ome617 swap ....had a hand in the one you posted the vid for ....(big red) it leaves no room in the engine bay front to back ....
theres cooling issues atm and there was also moving the rad around ....
we've tossed around a few ideas and for my personal rig im gonna be doing the 4cly to give me the desired room in the engine bay and the slap a turbo on it after, so many choices for that tho ..... we've got a hino turbo that needs a rebuild, or i could but a benz turbo ... or the sunbird turbo ....

 

I wonder how often D4D's float around?

 

I don't think the 7.3L would be a good motor in a truck this small at all. It would be crazy heavy and it wouldn't really be fun to drive. The body roll would be crazy and the weight distribution would be horrible. Besides there is no reason to put such a massive motor in a Toyota mini truck. Weren't these motors used in school busses too? I'd go with a motor more suited to this size a truck. Even with this huge motor you will never be able to tow anything an F250 can because the truck is too light, no brakes and not big enough. You could go with a Toyota motor like I did with my 3.0L TD or a 2.4L or even a 3B or a 13BT from a Cruiser. Also another motor I've heard some good things about is from a Mitsubitchi. Not sure what motor is was but I think it was a 2.8L TD or something like that. I'd stay away from the TDI's as the are smaller and when running hard for long periods the EGT's will most likely get into the scary range. I like my 1kz-te as its got lots of power and decent mileage but if I were to do it again I'd find a direct injection motor for the mileage aspect. But I love that my 1kz will start in all but the coldest weather we get here. And tons of power offroad.

I'd love to drive a D4D as the are the direct injection version of my 1kz. They have more power and torque and have a variable geometry turbo so a very nice and flat powerband. Great on fuel but they are highly electrical which kind of bothers me. My 1kz is at about 391000kms and its going strong with no noises and it barely uses oil. The UOA's come back great all the time.

 

no way a 7.3 could fit. they barely fit in like a 01 ford truck. takes up the whole engine bay and the turbo is right by the firewall

 

you can stuff the 7.3 in the yoda without extending the frame.. my buddy has a 2003 dodge cumins moder in his 1990 4runner... so it is possible... with work... but if it was me doing it i would have went with the little Caterpillar moder but thats just me..

 

i want to see pictures of this 4runner

 

Thats a lot of motor for a Yota, might as well build a complete frame for it. I think it can be done without alot of mods to the frame but a body lift and a new firewall would be in order. Anybody know how much the 22RE weighs?
