i heard somewhere that the 6.2 gm deisel is about the same size as a 350... well that got me thinkin, if i could fit a 350 in my truck, why couldnt i fit that? so i was just wondering if that was true or not... it prob weigh a ton and not be practical, but it would kick butt

kenbo53

never seen one outside of a truck but i would say ited be quite a bit bigger and to drop one in a toyota would take an ungodly amount of money time and fabrication skills

First, the rated power isn't all that much: 143 hp @ 3,600 rpm / 257 ft-lbs.

(A L98 TPI V8 has 245 hp / 345 ft-lbs @ 3,300 rpm. Smaller, lighter, more low end torque. Gasoline, though.)

If memory serves, they're based on the Oldsmobile V8, not the Chevy. So it's bigger. Not that much bigger, though. The Olds and Pontiac blocks were physically small considering up to 455 ci displacement. I'd like to know if it'll fit a Toyota, but the Chevy V8 is such a tight fit already, I have my doubts.

Also, being based on a gas V8, it's not the most reliable diesel.

Swaps I'd like to see:

Cummins 4BT
Pontiac 455
Whatever is in those Isuzu NPR diesel box trucks
Hybrid engine/motor/batteries from a Prius
Electric motor

It has the same engine mounts and bellhousing pattern, but it's physically a little larger and 1 liter = approx 61 cubic inches, So 6.2L = 378 cid

6.2 was its own design and although it still had lower end issues, it was way way better than the 350 diesel in early 80s caprices and oldsmobiles. 6.2 s are tough to find alive, gm no longer carries them and from what I remember the 6.5 is the direct replacement. I dont think it would be a big issue with cramming one under the hood, but all the other stuff, especially trying to get a big enough radiator to fit might suck up more space than u have. I think this swap has been done in land cruisers b4.

Don't get me wrong but... The american diesels are very poor... 6.2 liters for only 143HP? In Europe with so much liters a diesel would have like 500HP!

actually american diesels are way better now.the 6.2 is like a early- late 80's engine. i used to drive an 02 ram 3500 with a cummins 5.9. it had about 245 hp and 550 lbs torque. but they can be upgraded to 500 hp so easily, the cummins 12 valve especially. now the power of diesels is 350 hp and close to 700lbs torque. back in 80's diesels were garbage.

teh GM6.2, like pretty much everything Gm makes was/is a garbage motor. We had one in our sanding truck when I worked at Timberline and trying to get a loaded truck up to the lodge from the ODOT lot on 26 was an all day affair. It was based off of a gas V8 and was never meant to be a diesel motor.

The 6.5 was a replacement adn it was a better motor and even had a Turbo on it at one point, but it was still nothing like the new breed of DI diesels or even old Cummins motors of the last 15 years.

As far as the "euro" diesel's and how hot they all are... yeah that's what DI and turbo's do, not all of these motors were quite the screamers they are now years ago. Lest we all forget the Merc and Volvo diesel's of the past that pretty much ruined Americas perception of what Diesel's can do.

In terms of A diesel swap... there are SO many better options to fit in our trucks. most of wich came from mother Toyota in other parts of the world. Personaly I feel it's insulting to put GM garbage in a Toyota, that goes for all of their motors.

To the GM "garbage" comment, boo hiss. This is a Toyota forum yes, but lets keep in mind GM and Toyota represent different vehicles for different people for different uses. The diesels you are all talking about were built for towing purposes, and yes they have come a long way since the 80's, and they are used for towing vehicles etc.
The European diesels the other fella was talking about do put out a lot of power and get GREAT mileage (ex. VW 2.0 TDI etc). However, the diesels being put out by the American automakers are able to be tuned to get great mileage while maintaining high power input.

Basically lets try to keep comparing apples to apples here ya'll, otherwise good guys start to exchange ill words, and don't we all just want to get along and talk about badass cars?
To purpose a diesel swap on a Toyota, in my opinion, is an amusing thought at the most. Yes, more low end power and big boy exhaust note is appealing, but the time and money not to mention the heartache fab-ing up parts to make this swap actually WORK far outweighs the benefits of attempting such a switch. PUt outrageous amounts of money into a bulletproof motor such as the 3VZ or the 5VZ and make it unique and just as badass.

Diesel_Freak

I stand behind my statememnt... along with the 2.8 Gas-V6 the 6.2 Diesel may be one of the biggest turds in world engine hostory. And as far as something to swap into a Toyota 4x4... Wow WHY??? Unless it's free and going to improve your truck somehow I see NO merrit in using this engine in a swap.

Cheers

the 6.2l is a dog and a bomber u dont want it my truck has one

I've seen some swaps using a Mercedes 5 cylinder diesel that look interesting. I've also seen a VW swapped in. I believe it was Flash that did a GREAT job on and write up about swapping in the VW.

ozziesironmanoffroad

drop in the cummins turbo they have in the new dodge ram 3500s. now THATS a diesel.

seanmearse

if the 6.2 diesel sucks, why did it succesfully carry my ass around for three years in the military? i was a 63B10, which is a light wheel diesel mechanic, also H8, recovery specialist. Now, i am not saying i am some diesel guru, but in those three great years of my life, i never once had to change out anything but batteries, starters, and generators. granted its not the most powerful engine, but it got s**t done.

For my next project, I want to build a late model 4-door Dodge shortbed on a 1-ton 4x4 chassis with a Detroit 6V53T 2-stroke diesel. Now that's a diesel!!

This month's Road and Track has a review of the new BMW 335d diesel. 0-60 in 5.3 seconds, 35mpg. That'd be the swap for a Toyota pickup.

grant526

That BMW swap would cost WAY more than the Yota you'd be putting it in!! lol

But yes, this could be an interesting swap. Just don't let BMW in conjunction with Car&Driver tune it for you. I saw them race 2 of these at the NASA 25 Hours of Thunderhill a couple years back. The blew the 1st motor in the "tuned" of the two cars within the 1st 4 hours. . . Go figure!

sorry if im sounding like a smart ass but then new duramax diesel motor for the half ton trucks is a 4.5l

LMK

General Motors plans a 4.5 litre 72-degree[10] V8 for light-duty applications which will be built at GM's powertrain facility in Tonawanda, New York after 2009. Designed to fit in the same space as a Chevrolet Small-Block engine, it is expected to produce over 310 bhp (231.2 kW) and 520 lb·ft (705 N·m) of torque. It added urea injection, 29,000-psi (2,000 bar) piezo-electric common-rail fuel system over previous Duramax architecture.[11]

It would initially be targeted for the Chevy Silverado/GMC Sierra and Hummer H2.[12] Unlike previous Duramax engines, the 4.5 liter will be designed and built entirely by GM, without assistance from Isuzu.[13]

As of March 2009, a GM spokesperson stated the engine project has been put on an "indefinite hold" due to current economic conditions.[14]

I travelled Tanzania in 2001 and saw a 4runner called the SSR. It was a turbo diesel and I wished it was imported here. Anyone know about it?

The 6.2/6.5 was a great little motor. Get the facts strait before posting. It will fit any where a SBC will go and our very cost effective little motors. As far as simple to work on goes its about as easy as it gets. Keep in mind this engine works on late 70s and early 80s technology so its a long way from the common rail computer ran injection systems we have today. However that is also one of the pros to the 6.2/6.5 engines. Not only are they simple but they are cheap. I could buy a new long block 6.5 for what it cost me to replace my injection pump in my LB7 duramax. I have also owned both a 6.2 with a banks turbo and a 6.5 with a factory GM-8 turbo and both had decent power. My 93 ext cab was a 3500 4x4 and had 380,000 on the stock bottom end when i sold it. That truck would also get about 20 mpg on high way which was pretty good on a 5500lb truck. My 85 had 33s and a factory 6.2 with some 6.5 upgrades and a banks turbo and once again she would get 18-20 mpg with 4.10 gears and a 4 speed.

Now if your looking for a power house then no these are not the engines for you. If you want any real power with them you have to go turbo. However a stock NA 6.2/6.5 can make around 160 hp and 280 tq in stock bone stock form by adjusting timing and the injection pump. Now im not sure about you guys but thats a lot of torque and decent power. Add a turbo and your looking at adding 40-60 hp and 80-100 tq depending on boost, fueling, timing, and how hard you want to push it.

You also have to factor that most guys with 4 speed trucks get 18-22 mpg with the 6.2 and 6.5. We are talking about trucks that are a 1200-2500 lbs more then most yota's so you should pick up a few mpg over that.

Like i said i do have a lot of experience with both the 6.2 and 6.5 and from what i have seen they are strong little motors that will last when taken care of. They are cheap and easy to work on and can run on the crappiest fuel known to man. The us military still uses the 6.2/6.5 in the M998,M1097,M1114,M1151 and a few others that i dont feel like listing. The M1151 weighs in at over 14000lbs with combat load and in iraq we would see about 20000-35000 miles out of our gun trucks before they would be toast. While this does not seem like a lot keep in mind you are talking about 140 degree weather in the summer, being run balls to the wall every day (foot to the floor 90% of the time), dealing with major dust and sand (kills even civilian vehicles in 40-60k) on top of that most operators dont take care of there trucks (run with our oil, little to no service, no coolant, etc) under these conditions just about any engine would meet its maker. However i have seen more then once where these engines have been over heated, run with out oil, neglected, and abused yet they still keep on ticking.
