Built 1992 6.5l 2500 GMC 

What all did u do 2 ur truck? I have a 93 I want 2 build. Dose it still get good fuel milage?

Thanks!

@@erickovacevich1 your welcome do still have your rig

@@GRVDGRLIFE4 no I actually sold it about a month ago. Really wish I would have taken more videos while I owned it!

What are you swapping?

Oh, sorry!

I never did dyno this truck, but I sure wish I would have before I sold it. I've never really seen another 6.5 with this much done to it, so I couldn't even safely make a guess of what it was putting out! I hear you about the cost of new trucks, nothing quite compares to the sound of these things either.

@@erickovacevich1 I'm about to, to both my 6.2 and 6.5 😁 what do you think your power numbers were? I wanna TRY for 300+whp

Check for blow by or do a compression test if you are able to.

pmd

If your experiencing oil in those areas around the turbo, sounds like you might need a new turbo is it is leaking the oil that it uses to cool itself, your starting issue is likely a pmd issue and discovering the turbo was by accident

@@raj9223 I found out both heads are cracked. Got new ones,all gaskets, glow plugs and injectors. Ive got the new heads on and torqued so far. I tried to turn the turbo fan by hand and its barely moves. Is it supposed to spin easily?

Change ur lift pump

These engines are very sensitive to mods. In my area i see them for sale all the time blown up alot of young guys were getting ahold of them and hooning the shit out of them.

​@@Big-lronThis truck had supporting mods done to accommodate power says in description.

From what I've been reading lately, 12 to 15 psi is the max. Unless you get one of these trucks very cheap, it's hard to justify putting money into a 6.5, but if you pick up one for $1,000, it might be worth something looking into

The Tractorman will make it much cooler and it's not a complicated setup. Would recommend

@@erickovacevich1 2nd the comment on the intercooler, definitely worth it

Diesels don't use blow off valves as they are not throttled

@@JustFixIt99 pretty sure that isn’t what he is talking about

Water methanol injection controller

JHorse508 blow by is common in clapped out diesels in general, just because they have such high compression compared to regular gas engines!

I found them on craigslist and they were just some sort of universal seat and rail combo. They fit like a glove though. Sorry I dont know any more specifics lol

Water/meth injection

Intercooler ****

@@12pawsinn ya, my bad.

Straight pipe 4 inch

180hp and 440 foot pounds of torque

@@goofyboi7061 215/440*

I'd recommend getting it tuned that's the best thing u can do to a engine

4in exhaust, 2.5" crossover, 3in downpipe, a reputable tuned ECM, new harmonic balancer, new crank pulley, new injectors popped to 2300psi, after that... cooling mods... those, you can google..lol. :)

Getting rid of it... haha go buy you a 5.9 or a 7.3

@@nolansmith4972 7.3 and 6.5 are same shit pretty much

Not sure on the cost, Chris from twisted steel performance built the engine.

That's why I like the 92-93...all mechanical 6.5 turbo! I have 2 92's..one 2x4 and 1 4x4..both 5 speed granny low

It was just flat black spray bombed in my driveway. Turned out pretty good, cost like 50 bucks lol

@@erickovacevich1 thats what i wanted to hear how many cans of paint what was the air tempatue was there wind what did you ocver your windows with

@@rileykirk11 I actually used a cheap air sprayer from fleet. Like $20. 1 gallon of rustoleum if I remember right. Kept spraying coats until it was gone. Just newspaper and masking tape over the windows.

@@erickovacevich1 how about the grille did you take the panel off? also after rust is set in is there anything to slow it down specifically in body panels

180hp

@@goofyboi7061 that's stock... he is running 22 psi. With intercooler and 4inch exhaust on a built engine big turbo. So most likely 265 hp 470 lb of tq

Meth injection, bigger turbo, different turbo blade size, kennedy waste gate, hardblok poured in water jackets to strengthen block, inter cooler, double oil coolers in front to keep it cool, bigger mariner injectors, built mechanical fuel pump with higher flow, bigger lift pump, probably missing a few things lol.

Eric Kovacevich nice set up! where did you purchase the intercooler?

180hp stock

All of it. Is what I would guess

Buying a house. Definitely miss it!

damn. I hope you're happy with your new house!

Intercooler

This truck came stock with an ugly wooden flip up console, I actually ended up buying a different flip up console off of craigslist and fabricating some brackets to make it fit on the stock console frame.

@@erickovacevich1 any chance you know what it came out of?

@@littlejvl4 I never actually knew, I just measured the stock one and found one with the same dimensions. Sorry!

@@erickovacevich1 no worries thanks so much

Looks like a dodge maybe I’m wrong but ther big and square like that

Zach Weber hey thanks! It's a 4in strait pipe off the turbo. Trucks for sale of you want it!

Eric Kovacevich I would buy it but I'm live in Canada and I recently just bought. A 1994 6.5 step side. Good luck selling it though 👍🇨🇦

Eric Kovacevich is the truck still available?

Screaming craigslist find!

That's 1st low sits where 1st is normally

@@fredlandron6679 oh

@@fredlandron6679 Jesus Christ, don’t be so simple. The NV4500 is a FIVE SPEED Transmission, it’s not a four speed with Low. 1 2 3 4 5, no matter how many extra “letters” they put on the damn shift knob. I was at a drive thru the other day and asked for a Medium Drink, the asshole on the intercom said “we don’t have Medium drinks, only small, Large and Extra Large”..... are you sure that wasn’t you working the drive thru in there!!??

@@jlsgarage872 don’t listen to that dumbshit, yes, dude took off in second gear.

1. I'm guessing he's at less than 300hp. 2. That duramax would walk all over any 6.5. Theres no comparison between the old style diesels and the new common rail engines. Stock the 6.5 is rated at 180hp and 440 torque, the duramax stock is close to 400hp and over 700 torque.

@@jgpenniesworth442 Thanks! Yeah, that's pretty much what I thought, gotta ask though!

*Holds up crucifix* GET BACK YOU DEMON. Jk of course. I just like the 6.5s and if you do almost all the work yourself it's worth it in my opinion.

I agree it cst a shit load of money to even make these reliable then how much to gain horsepower 12 v any day over a 6.5 I have a 6.5 and it’s stock I would not waste money on one of these engines to get horsepower ther great on fuel but that’s all I can say good about them I’ll take a 12 v any day over one of these if I wanna make power good to drive from a to b but in all reality it’s not worth the money to try to make these go fast it would cost a small fortune to get horsepower out of these motors

@@jeffleblanc8850 you are just a greasy dodge owner pretending to own one of these. The 12 valves are also gutless turds

Not sure if this helps any, I couldn't really say for certain

98 Chevy k1500 Ryan just sold it Haha

@@erickovacevich1 oh lol yeah it's a pretty awesome truck. I'm going to be getting a 95 6.5 this weekend should be fun.

Exciting, goodluck with it all!

@@erickovacevich1 how much did you sell it for? Looks like a good truck I would of driven up from oklahoma to buy it.

Unknown unfortunately:/

wesley collins 50 horse and 600 ft lbs

@@JohnD595 😂😂

Ill tell you it isnt over 450 fully built the crank cant handle any over that. Iv had many of these and bam crank goes every time time to up grade to a cummins or dmax

Aaron Hilt, could easily be over 400. I’ve talked with Heath from Heath diesel extensively and the 6.5s can hold 400 with the old block set up as long as you take care of them. His old bonnaville truck is 500 on an old block that has parts from a 6.2 and the truck I’m building now will be around 550. He had 3 shop trucks all between 375-450 hp all stock except for boost which is up around 20lbs. He’s had them for years and they get driven frequently. With the new optimizer 6.5s you can safely run higher egts (to a point) and push more power. Before anyone says anything about them not handling boost that’s b.s. as well. I’ve had mine 303k miles, stock head gaskets and daily driven 160 miles 6 days a week at 25, screw the “can’t go over 12-15 reliably crap. If you ask Heath about the build plan on his Bonnaville truck he will tell you before they went with twin turbo they were thinking of compound turbos upwards of 75lbs of boost. The problem is NO ONE takes care of these engines properly and EVERYONE (myself included) has read online forums from keyboard commandos saying how shit these engines are. If you know the weak spots (harmonic balancer being one on the older blocks) then you can avoid 99% of all the problems they have. Second issue is they take them to a diesel mechanic to get them fixed and the problem with that is these aren’t dmax or Cummins, they’re a 6.5. Compression is different, boost is different, block is different. This guy did his research, and took his time building this truck and he did it RIGHT. I can promise you that was up near 400 or more. Not trying to start a fight, just sick and tired of misinformation everywhere on these things🤙🏽

In this particular lane, the 7.3 Ford idi turbo is better in almost every single way. When the Detroit engineering team were asked themselves about the comparison between the 2 there response as to the pros over the Ford was weight and a slight fuel consumption advantage. When asked about the pro's of the IDI turbo their answer was, and i quote, "but the Ford is heavier"... Lmao

yup I heard that miss as well!

I'm going to go ahead and guess that the fact that the owner isn't concerned, the tach being dead steady, and there being no noticable vibrations means that there is no miss...

​@@6484373 Hi idiot. Those are not tests for missing cylinders.

@@ThunderAppeal You're right, they are not tests, but they are a simple giveaway when there is a miss that I was just pointing out. Once again I think the fact that the owner doesn't have this concern, and that he pinned your comment shows that the truck runs fine.

@@ThunderAppeal nah you just don't know what you're talking about. This truck runs great.
