S6.5 AMG
 

I'll just leave this here. 1994 s10 zr2 pickup with the engine, trans, transfer case, and hydraulic brake assist/master from a 1993 k3500 chevy. 6.5 turbo diesel, 4L80e, hydroboost, custom shafts, electric fans, hd mechanic fuel pump that is turned up, manual waste gate, 31 inch mud terrains. Included a pic of the one ton going off to scrap after it was wrecked :dang: and some of the work the s10 does that got me thinking a few extra foot lbs would be in my best interest :humm:. Thats a C2500 suburban with a electronic 6.5 with a heath programmer, diamond eye exhaust, cold air, and boost master. Turbo diesel all the things! S10 is on full time daily duty and i have the 6.5 running the oil pressure, engine temp, fuel level, and volt gauges from the s10 but havent ran the wire to the speed sensor yet :w2:. Not sure what the fuel economy is without a speedo/trip but its been great so far.

Nice rig. Looks like quite a feat getting that in there.

I agree that did look like a rough fit, based on the pictures. Have you thought about adding a leaf to the rear suspension?

i have a set of air assist rear shocks in the rear, they just dont get the job done. I think im going to have to get a set of big boy air bags so i can adjust it. The burb does carry the racecar trailer allot better though huh lol.

That's a tight fit! Other than not being a fan of the turbo master or heath products I really like the rigs!

Is that hose the air intake? I'd re route that to lower intake temps

haha, and where would you reroute that. As is that is literaly the only path if i want the hood to shut. Soon, its getting a holset and a snorkel, until then thats how 10 lbs of shit fits in a 5 lb bag. Its a very thick rubber, the bigger problem there is the 4.3's airbox and filter. I have considered moving the battery to the drivers side and mounting the air box over there. would clean things up a bit.

Whats wrong with heath? or the turbo master?

Heath was a self righteous d bag when I tried to ask him about getting a smokeless tune for my a team turbo. He told me to buy his turbo master and that's all I'd ever need, its not true, the stock turbo is a restrictive POS and he never took the time to properly tune the better turbo (KOJO did).

Funny how Heath sells and aftermarket turbo now though.

weird, i contacted them when i bought my suburban to ask questions about his products and he was very helpful. even offered to run me a new flash because the one in my burb is pretty old and im having some high egt issues while towing. Sucks you had a bad experience but its the opposite of what i got. :humm:

Moved my battery into the backseat, moved my air box to the passenger side (just for you tanman ;) ), and found a few little wiring issues. Pictures coming later when i bring it in from the cold to run a new ground. :argh:

Got it pulled in and found some unused floor space and added a second battery/ran my ground down to the frame. And yea i know i have a agm and wet cell battery tied together and they will cannibalize each other when the truck is off. Ill be ordering a battery isolator on payday and until then i hooked up it up so the interstate is easy to pull off at night. Time to hook my invertor back up and move to finalizing the engine harness, its rough having a project truck as a daily driver. Hopefully ill have a new center section for the suburbans rear diff soon. :w2:. figured id include a picture of its busted front end lol, it gets wheeled frequently.

Yup, that intake is better.

Most people with a non heath turbo don't get alot of specific help, he has very little interest in helping other turbo's run right. Most just get a modified Vin F performance tune that adds fuel at the top or bottom.

I'm just going to start this post off like this. Not bashing engine choice. What ever floats your boat. What are the benefits of the 6.5 engine? I know it's a lower torque motor and would be more friendly in the s10 you have it in. But I just wonder the thoughts you have on that engine. Because I am sure that I and the Internet both have the wrong opinion. Look forward to your reply.

6.5s were designed to be a cheap, efficient, durable work horse. Was never intended to be a high hp engine. Truth is when I bought my one ton I didnt want or could afford a round bodied silverado with a dmax. I wanted a mechanical injected diesel. If the solenoid has power and there is fuel in the tank it runs. There is a reason the presidential limo and humvees have 6.5s. Simple and reliable. It surved me incredibly well in my one ton towing a two car trailer and every belonging my family has from washington state to iowa when me moved. Im a huge fan of 6.5s, sorry you and the internet dont share that opinion but mine have never let me down. Another plus is it was designed to fit anywhere a 350 small block fits. Why run a big dollar big power dmax when I love and already own 6.5s? :nope: 6.5s have a bad rap because of the hp race and owners and mechanics not understanding them. As for me and my fleet, I couldnt ask for better engines. I have two 6.5s a mechanical pump and a electronic pump and my wife drives a 16 silverado with the new 5.3.

Whats wrong with a 300hp diesel anyways? :humm: id like to add that im a bit of a prepper in someways and I dig an engine that will burn any fuel, unaffected by emp stuff, doesnt require def or have any emissions equipment, or have any exotic/expensive parts. Truck has a semi cabin invertor in it and now dual batteries. I could set it to high idle and power my home (partially) through an emergency or dump any filtered oil/some gas in the tank to keep it running if shit ever hit the fan.

Wifes cluster, 617 I found abandoned at a local trans shop (can make it mine if I want, and I do lol), and whats left of my suburbans gov loc.:w2:

I like my 6.5's but enjoy a good romp in the dmax. Problem is all my 6.5's walk away from my dmax when used for dd and tow just as well. Unloaded does show the difference new tech makes. If I push my dmax hard enough to out run my 6.5l towing heat and the tranny are at risk, if I push it hard enough to keep up with my 6.5 on dd duty then it gets crap for mileage, if I try to out run the dmax unloaded my 6.5 gets sad.

That right there gives me a different perspective on this engine. Thanks for the information. You actually bumped it up a few knoches for me.

Glad I could help out.

7.3 and gm 6.2/6.5 shared the same db2 pump with different internal settings.

Different strokes for different folks. When the 6.5 came out it was a direct competitor for the engines that were out at the time. But when the hp race started gm ditched it for the more modern dmax platform. My mechanical diesel has a 6.2 governor spring which raises its max governed rpm to ~4200 and its internal fuel limit turned up all the way which people claim bumps it to 300hp~ with a mechanical wastegate set at 15 psi. My electronic pump has mechanical boost control (also at 15 psi) with a 4 inch exhaust, intake, and a heath chip of unknown rating. The suburban hauls like a champ and i have never been in a situation where i have wanted more power. The s10 feels sluggish and im trying to figure out what happened to that engine during the wreck/storage cause it doesnt run like it used to. Same gearing in the s10, 3.73 which is rpm limited to ~110 mph so its not a wierd gearing issue (suburban is also a 4l80e and 3.73. Im not sure what the 1 ton was).

The almighty 12v cummins ran almost a 1k rpm less so had to be geared less favorably and made nearly identical amounts of hp and tq. cummins max tq 1500, 6.5 1800, 7.3 2000 not much low rpm advantage there either.

No one likes that sharp high speed governor drop off at high rpm, fix your 6.5 with a 6.2 governor :tu:

i need this in my life.. just sayin :humm:

The "Marine" 310 hp. 6.5L injection pump Part Number is DB2831-5722.
The pump uses a four plunger rotor with .310" diameter plungers. Full load is 3,600 rpm. The test plan shows 3,500 rpm 73.5 to 76.5 mm/3 maximum output. High Idle is 4,100 rpm.

Adding a couple pics. Suburbans old vs new carrier. Suburbans gauges and turbo master. S10s engine sticker/ratings, s10s trans controls.

Just got a go-pro. hate it or love it lol, videos are going to happen. :c:

Where does the exhaust come out? Behind the front tire? Sounds pretty good too.

Yea, took the oe down pipe and cut it in half, twisted it, and welded it back together to follow the contour of the wheel well. It terminates right after it 90s to go back right behind the wheel outside of the frame

Made the video allot shorter, added some towing :choochoo:

Unique diesel builds a 150cc db2 for the 6.5l and also has a pretty quick 82 c10 race truck.

I also really like the a team turbo found at Leroydiesel.com with a KOJO tune.

I have a stock 93 db2 turned up, a team turbo, bd spool valve, and a 5 speed in my 93 k3500. Same set up in another truck dyno'd 272hp and 520tq at the wheels, haven't dyno'd mine but I turned my fun screw back for towing without head studs.

did you notice a big difference switching turbos? the s10 is going to get a big ball bearing turbo or a holset, havent decided yet. How about the spool valve, do you feel like that was necessary?

The a team is a huge non gated t4 turbo, its a custom modified and built Mitsubishi td07 off an escavator. The truck is used to tow heavy with and off the line I could blow some serious smoke when grossing 40k.

I've ran the a team on other trucks just fine and with an auto trans it lights better but it helps of you change the shift points higher and add/or a 2000-2200rpm stall triple disc converter. Makes the turbo start from its power band and can still be locked in at lower rpm if you feel the need to bog it.

My 94 k3500 has a custom KOJO tune to light the turbo at lower rpm and clear up the smoke even with a 5 speed and a good load

I just looked up a teams website, good looking turbos but almost no information lol. Price is alright, and it does look bigger. You pretty happy with yours? Do you have a external wastegate? What kind of pressure are you running?

They are pretty tight with the sizing info.

It's awesome for my needs, very tough and 100% tech support and great customer service. Kojo's tuning for the turbo is very well tuned.

Most I've ever seen was 18 psi, others claim to have hit low 20's. Fuel is the only thing holding it back but its supposed to be good up to 600hp. No wastegate needed

non wastegated diesel turbos are sexy :humm: I'll have to keep them in mind, it looks like a good fit. Only real concern i have is using a 600 hp capable turbo on a 300 hp engine sounds like it would have it very low in its efficiency and probably pretty laggy too. Just thoughts, no numbers to back that up.

It's power band is higher and produces boost slower but accelerates quicker

Got the burb going, kinda nice having some comforts back lol. The s10 is going to hold the trailer down for a bit which will be nice. Kinda stressful driving a new project everyday even if it never let me down :w2:.

Brought the next toy home 1981 aquamarine 300sd with a turbo 617 diesel. s10 has been doing great on daily duty, took it wheeling the other day and beat the brakes off of it. drove it to work the next day. Having three diesels leads to plugging the wrong one in every now and then and i have discovered the s10 doesnt start nearly as well with that mechanical pump as the suburban does with the electronic pump.

The mercedes started out with 4 year old diesel since it has been sitting so its cold-start ability is still improving. So far i have had to adjust the bands in the transmission, adjust the vacuum modulator so it shifts right, turn up the delivery valves (more fuel), adjust ALDA all the way out so it fuels pre-boost, bypassed boost limiting solenoid to prevent it intervening in my shenanigans, advanced pump timing, rebuilt valve body/new fluid, changed oil/filter, fuel filters, ordered a new air filter, and blew a tire on the way home from the shop. After i get a few cosmetic issues sorted out the back plate is coming off of this pump and is getting set to race mode :bat:.

I love my DB2's but a DS4 will almost always out start them. This is why I don't jump on the db2 swap band wagon.

I can back that up 100% The suburban always starts well and smokes less (sometimes substantially less) than the s10 with the mechanical pump does. s10 will misfire for a while after starting while the suburban levels out quickly. They are night and day different during cold starts below 30*. After they are running though the differences narrow quite a bit. both hot start the same, idle the same, accelerate smoothly. I believe the cold start difference comes down to the electronic pump being able to advance timing furthur, if i dont run the cold start advance in the s10 it is a absolute nightmare to start/smokes like crazy.
