I love seeing people using these. I have a 6.5 599 block in my 1991 FJ80. I pulled it from my 2500HD a couple of years ago. With 180k on the engine, the cylinders still had good cross-hatch. Bottom end looked like new with no visible cracks. I did find cracks between valves on the heads at the rear cylinders. I cleaned it out and put new heads on with ARP studs. I added all of the updated cooling components along with the best fan and clutch I could find. HX35 turbo, 4 inch in, 3 inch straight out. I'm only running 15 lbs of boost. It's a little hazy pulling hills but EGTs are good and it has plenty of power for the Land Cruiser. I can get nearly 20mpg on the highway with 4.10 gears, 35s, and full-time 4wd through the 4l80e.

Nice to see another Suburban with a 6.5 getting souped up! Hopefully someday I can get my hands on a p400 or optimizer myself. I thought about a Duramax swap too, but decided to stick to older and simpler. These engines get a bad rap imo, they came out of the factory with a few issues, but once sorted they're solid as anything imo.

Dennis is tops! With their mixed history, I find it understandable that folks might not like them, but like you said, once you know you know.

My first experience with the 6.5L Turbo was while working at a Chevy dealership. We had to pick up a small fleet of trucks we had to sublet for modification. I chose a route back which took me over the back roads with some seriously steep hills. I was amazed at how the truck I drove pulled up the steepest hill, it kept accelerating as we climbed which wasn't an easy task for most vehicles. I also wound up seeing a fleet of these trucks towed in with blown engines. The truck shop mechanic simply stated much of this was probably due to what he called misuse -- driving it like a gasoline engine, winding out at high RPM or excessively lugging it. Otherwise he insisted it was a good engine. Over the years, with the experiences I've had working in the automotive repair industry, I have to agree; if properly maintained and not overly abused, they can be an efficient and durable engine. And who doesn't love that old school "clacking" of an old school IDI diesel?

Helpful helper tip: If you want grease on engine parts that won't be assembled for a while, ATF assembly grease is a great option because it withstands pressure and dissolves in oil. But if you don't have that around, plain old Vaseline petroleum jelly works just fine. It stays in place and readily dissolves in oil. It doesn't offer much resistance to pressure, but as long as your oil pump is working, it should be fine.

You can never go wrong with the old diesels. Sure they left much to be desired hp wise. They had a real chance at lasting 500k+ miles though and made enough torque to be fantastic work trucks. I have a modern 2011 duramax and while I love it, I love my 93 7.3 IDI turbo way more. Its probably gonna hit 700k miles in the next few years. Only major breakage was 1 turbo and 2 sets of injectors. It needs glowplugs since the early 2000's but I have plenty of ether.😂

Great video, awesome to see you and Pops working together :) And no such thing as labeling too many things when building an engine! Thank you for sharing the small details like tool part numbers. Did you remember to gap your rings before installing? A new set doesn't guarantee proper clearance Every P400 part is still available except for the block or full engine. The best head upgrade for a 6.5 is to run P400 heads, they have hardened valve seats and will resist cracking better than the stock Optimizer heads or any aftermarket one Also a word of advice to anyone installing timing gears- Don't assume they are plug and play. There's a recent aftermarket set that have the dots off by one tooth and several engines have had valves hit pistons and trash engines. At a minimum use the old timing chain set dots to align the cam and crank before putting on the gears Thanks for giving the 6.5 some love, they definitely have a trash reputation because of GM's penny pinching but when built and maintained properly can be a very reliable and easy to work on engine

I also thought that only the P400 had a forged crank. This is great news that the Optimizer also has one. Maybe I’ll go that route instead of a Cummins.

Those wrist pin clips are easy. Roll one end down into the groove, push the other end with your thumb to drop into the pin hole, snap into the groove with a pick or screwdriver. To remove, spin the clip until there is clip exposed in the little offset, grab it with a pick or compress with a screwdriver.

Good tips!

I would love to do all this to my 7.3 , i almost bought a 85 or 86 chevy army pickup with the same 6.5 motor , it was one tough looking truck

I bet a 7.3 would run really strong with just a handful of little upgrades and a big turbo. That would be fun to build.

I've been waiting for this day to come! Very cool to see a family truck get an engine and your dad is doing it with you. I am very happy to see you sticking with Detroit power and not going with something more fashionable. Now if only my CUCV engine would blow up so I can do this 😂

Great job. Very enjoyable to watch with some very professional looking editing and professional narration. Kinda sound like Mike Rowe there a bit. Cheers from Brandon Mississippi!

@WillometMotorFab Glad I found the channel too! Funny story. One of my best friends growing up in high school acquired a 92 or 93 silverado with a 6.5 shortly after graduation. The thing had a bad compression skip and was blowing a ton of white and blue smoke. Pulled the head on the bank with the dead hole and found a severely scored cylinder. From there we pulled the oil pan, removed the piston from the bad cylinder, honed the crap out of it till all the vertical lines/scoring were gone. (Really should have been bored but he was broke as was I). Put the original piston back in with a new set of rings, buttoned the motor back up and the thing ran like a top! Albeit it always had a little bit of piston slap on that cylinder until it warmed up afterwards. Ended up driving it for 4 years after that going back and forth to Northern Arizona University and it was still running pretty decent when he sold it! 6.5 DDs aren't as bad as people make them out to be.

You had me at “heavy, loud and smell”

NO END TAGS. I want to be able to watch the the whole video without end tags blocking my view

great job with filming i want to do total seal rings in one of mine some day

Greetings, fellow Texas diesel head!

Nice video. On the gear drive, ive heard from old timers that they can cause a harmonic that kills crank shafts or the nose of the cams in the 6.2 or 6.5. I’m not sure how true that is but just something you might look into just incase. Any 6.2-6.5 stuff I’ve dealt with I’ve talked to Heath about, they had the land speed record with one back in the 90’s I believe.

Thanks very much for watching. I’m glad you enjoyed it. I’ve heard the same about gear drives, and disregard their comments completely. Timing chain slack is far more concerning, especially for these engines with only a few thousandths clearance from valve at piston at TDC. Gears are broadly superior to a chain, though more expensive to install.

As a ford/international guy I naturally always have hated these engines due to the design/reliability/output and personaly have rebuilt the top end on one. having said that i really enjoyed your video and cant wait to see the finished project!

Great engine!

The gep p400 was the the absolute best available option until it was discontinued. I actually have a brand new p400 sitting in my shop. I got it from a customer who purchased it for a Hummer and I ended up Duramax swapping it.

@@WillometMotorFab The main issue with the p400 in many gm applications is the oil pan. The p400 uses a special structural cast aluminum oil pan that was designed for a specific application. At one point a couple of companies were offering modified versions of the cast aluminum oil pan and one company was in the process of having their own oil pans cast but I can't remember if they ever brought them to market before the engine was discontinued. I had a customer with a 98 suburban that experienced a broken crank due to the failure of a balancer and I installed a p400 in it and I had to modify the oil pan to clear the front differential which was the main problem. That was when the p400 was first released.

Ill have to keep that option in mind if the 6.2 ever goes in my 91 suburban or 85 suburbans. But I have a spare and that long block you started with is 8 grand.

Yeah, it's a fairly expensive platform, and you've really got to be a fan to justify the leap.

When I was over in Iraq we had a HMMWV with a NA 6.2 throw a rod through the block. We found a blown up armored HMMWV upside down in a pond. We took the 6.5 turbo and swaped it over to our two door soft top M998. Was still a slow turd, but it was a slightly quicker slow turd. I got pretty good at changing the fuel injectuon pumps on the NA 6.2s. Millitary 6.2s and 6.5s were a little different than the civilian versions.
