Re: Let's see those 6.2 Detroits!!!
What kind of power range we talking here?

Re: Let's see those 6.2 Detroits!!!
225hp-450 depending on what type of 6.5 its on. IE: Optimizer 6500, AMG/GEP P400, etc.
So technically Josh and Ryan, it is Cummins killing power. ![]()

Re: Let's see those 6.2 Detroits!!!
I'd call it 6.5 killing power. And you can get a lot more than 450 from a Cummins...and have it last.

Re: Let's see those 6.2 Detroits!!!
Nothing special about mine. Got ARP studs, a GM-8 turbo, 6.5 marine injectors, and two cracked heads. Gotta pull it back out of the truck and put some different heads on it.

500hp 6.5 = $10K + 500hp Cummins = $4K +/- But a high hp 6.5 is a helluva lot more unique than the usual Cummins swap.

The motor in my'95 blew up at 135k. I had that truck just the way I wanted,now knew these motors were iffy,and decided to buy a crate motor all brand spankin' new from Peninsular Marine in '03. This was a GEP higher nickle w/beefed-up main webs,18:1,125 GPM,dual t-stat,medium duty turbo,and reworked DB2 pump. It's their 300hp motor. I added an intercooler,had the gauges, '97-up air cleaner with AFE filter,custom mandrel bent cold air intake,and BD 4"mandrel exhaust. I had it dyno'd at a friend's shop and it came out to 315 HP. That thing was a real nice running motor. I had fun being the under dog and dropping jaws on some Ford and Dodge owners,as well as all the "new to trucks" Duramax drivers. Sure,they could get more out of theirs,but they never expected to eat my black smoke. I really enjoyed rolling up the mountains with power to spare as I passed the Power Strokes with fading power. I was really happy with that truck and many people were impressed. Unfortunately,one evening I hit a curve (at reasonable speed) where an accident scene had just been cleared...all except the antifreeze all over the road. It was like hitting ice when the roads had been dry everywhere all day and it was early fall. I corrected and it whipped the other way (like on ice) and I was sideways all over the road and got t-boned,flipped,and totalled. I saved what I could off the truck,including the motor with 15,000 miles. I had my '92 with just over 200k on original IP,injectors,and glow plugs in need of service. I decided to put the Peninsular motor in to get my money's worth (over $9000) out of it. I got about 30k out of that until one day it started making a racket so I parked it and hauled it home. I thought it was the NV4500 and pulled that. Well,you could pull the flywheel back and forth an inch or more.I pulled the pan and found both a broken crank and broken main webs. This was 45,000 miles on all new parts. So,it wasn't a bad balancer. My '92 still has it's original balancer. I dug that original motor out of mothballs and put it back in with the injectors,pump,and glow plugs from the 600# $9,000 piece of junk. I'm convinced it was too much boost. These things just can't take it. And,even N/As die prematurely. I still run these,still like them. But,I'll say there are too many failures and/or limitations with these motors to brag them up as a great motor. I'll never waste my money on modifications. Just run'em as they are and make the most of them. I get 20-22 mpg in my '85 Jimmy with 12.50/35 rubber and 4.10 gears. That's something not many can brag from a rig that can hold it's own off road and not need a trailer to get it there. I get 13.5-15 mpg out of my '92. Nothing to get excited about. It used to be a lot better,like 18-20 when new. Just being honest

Re: Let's see those 6.2 Detroits!!!
1982 Chevy Suburban, 3.08 gears. Excellent engine and gets high fuel economy. Headers made a huge difference in power and gained some fuel economy as well. Does fine for towing 26 ft Airstream trailer.
![]() 1990 Chevy Suburban. Only a 5.9 engine though. Put 10000 lbs trailer behind and you hardly know it. ![]() ![]() 6 speed NV5600 and NP205 transfer case ![]()

Re: Let's see those 6.2 Detroits!!!
Both are good engines. I can't say which one is better. Both are extremely dependable. The 6.2L shines in the fuel economy department and the engine behaves more like a gas engine since it makes its power more in the high rpm range. The 5.9L has more grunt power but takes longer to accelerate from 0-60 mph. It's also a bit quieter and smoother running than the 6.2L.

Re: Let's see those 6.2 Detroits!!!
Nice set-up on the '90. I haven't looked for a while,do you know if those headers are still made...and who made them? I kinda forgot about them after having turbo diesels. Now I have an '85 6.2 Jimmy and that would be a nice upgrade,then new exhaust/better flow mufflers. I believe it did make a noticeable difference with those installed. On the '91 6.2 Suburban I had I had a custom 3" dual exhaust system made and used 6" round Dynomax mufflers. I really felt a difference in power.

Re: Let's see those 6.2 Detroits!!!
I know Banks used to make them. I don't know if they still do or not. And on the acceleration on the Cummins, it's not hard to get that improved at all.

Re: Let's see those 6.2 Detroits!!!
There are a couple of good forums with some really good info on the the 6.5's & 6.2's. dieselplace.com & thetruckstop.us
I have several 6.5's and put about 800,000 on my 89 C2500 with Getrag 5 speed. 300,000 on the original 6.2 and 500,000 on the GM crate 6.5. 5w30 Amsoil with a FS2500 bypass filter. Oil change about every 20,000 miles. Weighed about 8,900 most every day. |
