It is nice to listen too. I myself do the same lol

Thank you.

Not sure, I made them up.

Heck ya it is. To have something this old, run so good and get 22+ mpg is as good as it gets.

No kit just used the Turbo 6.5 Exhaust Manifolds and Intake Manifold, Diamond Eye Crossover, Quadstar Intake Plenum, Quadstar Super 60, Hx Downpipe Adapter, Custom Turbo Oil Feed, Quadstar Oil Drain kit and a Custom Downpipe. There is no full kit for these so you'll have to aquire it piece by piece but doable.

I'm currently at a 10 sec 0-60 loaded and can get down close to 6 empty. These trucks are very underrated and all comes down to proper maintenance for longevity and reliability. 15 psi is alot on a stock GM Turbo back pressure wise. I regularly run 15-21psi without any problems but my engine is upgraded to handle it.

Coos Bay, Oregon.

I've never actually gave the truck a real fair chance to not blow Head Gaskets. The first time was after I bought it with the original head gaskets, the second was because a shop didn't clean the block up and didn't tourqe the studs correctly, the third was because I reused old studs that had been over tourqed and stretched and used the weak mahle 6.5 std head gaskets on a questionable block surface. So I got a new ARP Stud kit, resurfaced the Block and Heads,checked for flatness, tourqed to 110ft-lbs instead of 120 and retarded the timing to keep combustion pressure down. It's been over a Sun cycle (year) since my repairs and all is well. I now blow exhaust gaskets instead of head gaskets lol

She's a quick one and even quicker than in the video. I can get down to 6sec or under 0-60 with all the weight out of her and pump cranked up but the tranny needs rebuilt. Im currently at a 10sec 0-60. She also weighs alot and am at 6500lbs and was heavier in this video.

Check for starter brace have good connections bleed fuel system see if glow plugs work probably replace harmonic balancer after it's running

It's only a stock 93 6.5 turbo one. I just need to get an upgraded pump and should be solid on pressure after that.

She's pretty throaty without a muffler. I am planning to get my exhaust finished and put a muffler on then have it come out the back.

My crossover pipe gaskets are leaking as well so it kinda makes it sound wierd..

@@TheAscendedMaster ah nah dude, they all sound like that. it's just a turbo and a diesel. :) My brother and his buddies used to take off in their cummins and we'd make a joke about it.

@@TheAscendedMaster keep on keeping on. most of the men in my family used to be diesel mechanics.

I got an '86 suburban and pick-up.. both 6.2 and looking to make them both a beast..

Compared to when I first bought the truck and was completely stock to now is a night and day difference in all aspects. The truck has 3xs the power it had stock, starts the first key turn each time, gets almost as good of fuel economy ( stock was 21-31mpg, now gets 18-28mpg loaded), can climb hills and accelerate as quick as I want, engine runs smoother, quieter, more efficient and cleaner, never gets hot and doesn't let me down, 0-60 went from 22 seconds to 10- 12 seconds and I can keep up with any Cummings, powerstroke or duramax if they want to race. So yes, the truck is substantially more powerful than before and a heck of a lot more fun and enjoyable.

Honestly a lot more than is expected. Turbo exhaust and intake manifolds, Turbo, oil drain plate, crossover pipe, custom exhaust, up to par engine coolant and oil cooling systems, upgraded fuel system, filters and electric fuel pump, custom Turbo Intake, custom Turbo oil supply, pump turned up and in good working condition as well as injectors.

Probably more I just can't think about atm.

Thank you!

Oh man both those sound excellent! I unfortunately still have a bad tranny and torque converter so boosted launches and Dyno pulls are a no go for meow. It just slips 1st-2nd and 2nd-3rd if I get on her hard. Getting the tranny rebuilt w an upgraded tourqe converter and parts to handle the added hp & tq has been on the to do list but finding an honest, reliable and affordable shop is damn near impossible.

Trust me i feel your pain i got the really rare manual just finding syncros is near impossible

See and I would totally do a manual but with my Arthritis, Stenosis, Herniated Discs, Fibromyalgia ect I just couldn't handle it. Heck, I can barely hold my foot on the pedal or handle the steering wheel. But I'd still choose a TH400 over a manual. I like the TH400 a lot as it's the strongest tranny out there and has been since its debut. Upgrades are plentiful and it ain't gone out of style yet. Dudes are pulling the tranny from their new Camaro or pickup and putting a TH400 in and loving it. Sure it's a 3 speed but I still get 18-27+mpg in my rig right now loaded, which is probably the most impressive numbers for a Turbo 6.2/6.5 Diesel. I'll get this HD one built and be set for life.

Good luck brother on the build and your health

Thx man!

Thanks! Ya sure thing, whatever you would like know ask away.

@@TheAscendedMaster Do you have another way I can contact you?

​@@BradDDogI suppose my email. [email protected]

Lol not this engine. Lowered Compression Ratio and it's a 81' Red Block. She be solid.

Well. Id worry about reliability vs power to start with. Power is great but if the engine can't perform and keep up then it'll only do more harm than good. Id start by getting your cooling system in order and fuel system. Inspect the Harmonic Balancer, make sure the pump and injectors are good and working properly, new timing kit ect I did every single reliability upgrade to my 6.2 before giving it more power to ensure that it could handle it and not have new problems arise as less than adequate systems fail to keep up.

This is an old video years ago before I Turbocharged it. Was installing new Promaxx 6.5 Heads and ARP Studs here.

Old is the new gold compared to new vehicles. All mechanical made of iron and steel...built to last not to break.

Thank you!

Lol I have had the truck to a little over 90mph but damn is she screaming and sketchy.

She's actually a Canada made 1981 K20 6.2.

The drivetrain is completely stock and with 450+ HP and a already bad slipping TH400 she can't keep up with the extra power & tourqe. I also carry around 2000lbs in added weight from my tools, camper, spare, hitch and other stuff in the bed so shes always working harder than she should. If I completely emptied the truck of all the added weight she would be a freaking turbo diesel dragster lol

It's not made for power like a car, 15psi should be the max

It needs to be Turbocharged for that which means upgrades to everything. Intake, exhaust, fuel, cooling, reliability upgrades to engine ect.

Ok thanks love your truck by the way

Is there a better way to contact you

I'm a 64 year old man, usually on a 6.2 when removing are installing the heads, I stand on the side of the truck and bend over the fenders.

​@@sherwinstaudt1881Must not be a '81 4×4 K20. I'm 6'2" and I most definitely couldn't pick them up and off from the side without seriously injuring myself or dropping and breaking something. These Heads are not light and have always taken me to stand in the engine bay to remove and install them.

The 1982 6.2 was designed by Detroit Diesel for GM.

​@@TheAscendedMasterI drive one every day, 1982 Chevrolet C10, had it since it was new, 937,000 Mi on it right now, body of truck is in excellent shape no rust .all that has been done on it is oil pan gaskets, rear main seal, several water pumps, valve job, 1 injector pump, in about 50 or 60 starters, starters are junk thank God their lifetime, I've had just about enough on starters think I'm going to find me a gear reduction starter. Three junk 700 R4 Transmissions. I use it on the ranch nowadays very little road driving, if I Road drive it and keep it under 70 I get around 24 Mi to gallon.

195° Thermostat. Truck runs alot smoother, stronger and more efficient than when I had a 185° in.

And the way I want it too. A sleeper.

Nothing essentially. Through the mere possibility each were produced just like with most things and just like most things strive towards greatness it does too. Growing, expanding, creating ect Everything is built upon the other and leads to new things. I haven't gotten any further beyond which leads me believe that everything is a part of a Quantum Sentient Occurrence and all that is stems from this by means of every possible possibility for everything and anything all occuring, becoming, doing ect in every and any way.To be able to comprehend what I mean by everything and anything I mean the most crazy, insane, imaginative, out there, unrealistic, impossible idea, thought, thing, possibilities possible. Basically meaning anything you think is impossible isn't.

He must've swapped the original 6.2 for the Turbo 6.5 at some point which is a big upgrade in sense of power.

@@TheAscendedMaster Yes he did.

Of course not. Such is an idea that isn't real and is based upon religion and an individual misunderstanding the occurrence of what is while also failing to accept it therefore creating this idea that one believes that the nature of such is a so called "bad" happening. But in order to determine if what is happening is "bad" or "natural" comes down to if it is going to harm rather than help or if with intent is set out to harm rather than help. Anything that takes away without equally giving back is something I would consider to be unhelpful or in your terms "bad". But it will always be whatever that individual thinks of it.

@@TheAscendedMasterit sounds like you’re not fully committed to your opinion…If someone brutally r@ped and murdered your loved one, you wouldn’t call that evil?

I had one for about a year. Wouldn’t pull the hat off your head it was so weak. Only thing that kinda saved it was 456 gears but then it would only run 65 downhill. The one upside is you can’t kill em but o think I’ll stick with a 350
