I bought my 1981 K20 6.2 9 years ago. Knew absolutely nothing about it. Learned as things broke type of deal which is the best way. After 5 years of driving it N/A I spent the doll hairs on peiceing together a Turbo kit. Best desicion ever! Truck runs even smoother, has wicked more power and still gets 22+ mpg loaded. Truly an amazing engine.
I put a 6.5 out of a 98 Sierra in my 81 square body. I had to build the cross over pipe because they only made it from the factory with the newer trucks and they all have the front drive shaft on the left. My 81 has the front drive shaft on the right. The same side as the turbo. You can only buy exhaust pipes for the 95 and up with the 6.5 turbo.
@@RustyDreamsGarage my 83 came with an already installed military 6.2. But no brackets or anything. I’m hoping the ac is on the drivers side and I still can’t figure out if it’s supposed to be the short or long compressor.
@@RustyDreamsGarage and my ATS turbo system is already installed with all the original ATS stuff. Now if will just warm up a bit here in MN. I can get back to it.
I have a 1986 C20 Scottsdale Detroit Diesel and a 1986 K2500 Sierra classic Detroit Diesel.. I've been learning and thinking of turbos for both of them but the K2500 has a lot of external engine parts my C20 don't have..
@@RustyDreamsGarage it kind of looks like 3 filters but I'm still having trouble getting it started.. new batteries, starter and alternator from my C20.. figured it'll help turn it at least
@@dominiquehaines-86SquareBody the best thing to do is remove the glow plugs, only crack the injector lines, and crank it over to bleed the system. Open the primers on the filters to vent it.
I have a 83 k20 suburban sb350 with a nv4500 5spd im about to trade for a 90s k30 crew cab dually with a 6.2 auto and i wanna banks turbo it but is it even worth it to turbo and auto
30mpg? Im at ~12mpg right now w 700r4 conversion on 38s w steelies NA Jcode(84 M1008) my used Banks kit($700 plus parts trade) is going on this week. Banks got the 5.7billion contract to repower all the new JLTV dmaxs w his own D866T version engine.... cant see why they dont offer a 'retro' kit re-release to reinvigorate the 6.2/6.5 world and partner w AMG for P400s again or sell it with the Optimizer 6500 ready to go.
Ok. So 4.10 gears and 38” tires. Why are you expecting good fuel mileage from that? My 4 speed c20 6.2 routinely gets 26mpg. The red truck does even better with the turbo and a th400. Guess it’s how you drive it

I had a 1992 Gimmy C 1500 pickup with a 6.2 diesel and a NVG 4500 transmission. Very reliable and economical to operate at 25 miles per gallon.
The ATS turbo kit didn’t interfere with the AC system. But good luck finding one of those kits these days.

I’m buying a 6.2 so that was really helpful, thanks man!
Yep. Love my 6.2 also
Nice work Brotha!
Thanks!
Very helpful, thank you!
Thanks, informative and in my language 😅
Oh and why aren’t you hooking up your AC again?
I have a brand new kit to install. Just waiting to finish up the truck first

@@dominiquehaines-86SquareBody what kind of additional external parts?
@@RustyDreamsGarage looks too me like it has a secondary fuel pump connected to the intake manifold
@@dominiquehaines-86SquareBody some of them had two filters. A spin on on the manifold

@@DaPopaBear I’ve had 6.2’s with manuals and autos. My turbo with a th400 is my absolute favorite. Definitely worth it
But how does it tow ?
@@JasonY02 I pull a 18’ trailer with my old cars on it and you’d never k ow it was behind you
Where did you buy your turbo kit?
Off Facebook. Join the 6.2 groups and you’ll find one
