Thank you so much for your answer. Before you installed the Hammerhead Nozzles, did you have them pop pressure tested? What pop pressure are they set at? I think a GM 6.2 and GM 6.5 turbo diesel have different injectors. Maybe GM 6.2 diesel injectors are a little bit longer than GM 6.5 turbo diesel.

On my transmission I am also going to use an aftermarket TCM. I am thinking of Compushif or Microshift TCM. May the same TCM as you are using. Does your TCM have manual shifting option? I know that Microshift has that option.

For my use this summer I think my "stock" will hold on. But eventually I will have to reinforce it. Or maybe I will thorow in a BMW 530 6 speed transmission and buy custom flywheel, adapter plate for transmission to fit transmission to the motor, and custom clutch discs. I know BMW 530 6 speed transmisson have been used in the drifting circus (sirkus).

I am playing with the ideo of using both supercharger and turbo charger. I know Black Smoke racing used that combo in his OM 606 engine. That seemed to work well for him. Now he has a OM 648 engine. But for me, I do not know. Maybe i will have twin turbo setut, 2 hx 35 or 2 hx 40 turbos. But that will maybe be for next summer.

I would have been fun to riding shotgun in your car. It would have been to experience that instant boost from the supercharger.

Keep it up with your prodject. Looking forward for new updates.

I am also doing my prodject, a C 10 1980, regular cab, longbeed fleetside. Speeking of longbed, I am looking for a replacement bed. My bed is completely ruste out. I do not have neede welding skills to weld thin steel plates. So therefor I am looking for a another bed. If anoyne have one to sell, please speak out.

I didnt notice any difference in lengt, but you could be right.
No testing so I dont know.
The tci has forced lockup and manual option.
You can even retrofit paddle shifters.
Heard good things about us quick shift also i think its called.
The tci system was really simple to set up and worked straight away.
Needs tps sensor (machanical pumps have these) and rpm sensor (i used the one from the marine engine) but you could buy the correct rpm sender from ebay and fit into the front crank cover where the sender is on an 6.5td engine.

Dont know of any parts.
Live close to Bergen.
I'm not planning for any more just now, but I do want to build a twin engine and fit in my dually if I ever come by the right deal for another rebuildable marine engine project.
In that car it would be a lot easier to combine supercharger with turbo.
For simplicity i would use one big if combined with supercharger.
The trick there would be to keep the intake temps just right.
Before making the chargecooler work properly i would feel really well when intake temps passed by 130° farenheit.
It killed a lot of power in my case.

Is this that TCM you have Quick 4 Stand-Alone Transmission Control ? I have heard of it and I even have been on their web site. I like it has a manual shifting option. Also it can be retro fittet paddle shifters. I am thinking of using OEM steering wheel shift with a paddle shifting option in manual mode. But I have no idea of what paddle shifter to use or what brand it should be. Any suggestion?

Your are right about intake temperature. It should bee as cold as possible, lowering ambiant intake air temperature. That is why I will put on a big front mount intercooler. Yes, a big turbo combined with a supercharger should work just fine. From low rpm you will have the supercharger until the turbo "light on" on higher rpm level. The trick is to make it work. Maybe a extra waste gate could work to bleed off boost from the supercharger when turbo kick in?

No. I'm using the tci ez tzu.
Tci sells one that you fit between the steering column and wheel.
I have an bmw steering wheel laying around with paddle shifters.
If I get around to it some day i might fit them in the van, but NOT with the steering wheel.
No hate against bmw, but it would just be wrong.
Not that far in the prosess yet.
Need to get one more engine first before the plans start coming around.

I'd love to see your parts list and info on that bigger cam! Haven't seen anything but stock for this platform. Also what was that supercharger originally on and how many liters is it? Thanks

The cam came out of the hammerhead marine engine. It was an 2.4l autorotor/opcon/lysholm type, but it quit on me a couple of weeks ago (guessing it had more hours on it than what I was told)
Now i have ordered an 2.8l instead with a little smaller pulley thats supposed to be good for 30 psi, but I wont run it that hard at first. Thinking about going up to about 22-23 ish to begin with.

 

[Stabben]

Brand new 2.8l. Waiting for the last bits and pieces before i mount it. Gonna mount a pressure feed oil system with an fittings and a little larger heat exchanger for the water cooled intercooler.

Started an 2.nd build also of this engine since i liked it so much....
Will post more soon when parts arrive.
i have picked up another hammerhead engine and another 6.2d 599 block.
"The twin" is planned to go into my 84' gmc singel cab dually

 

[Stabben]

Next project. The hammerhead had a little seawater back in exhaust and into 4 of the sylinders so it was stuck. Looks like it has been stuck for some time also. I have salvaged all of the parts from it except the block, pistons and rods. Everything else was usable. Picked up another 599 6.2d engine from a 93' chevy van, pulled it apart and cleaned it, sandblasted and painted it.
Ordered all the needed parts for building "the twin" but still waiting for the main bearings. Installed the marine cam and lifters while i'm waiting for the bearings.
The next days i will be going through the heads and preparing other parts for blasting and paint so hopefully i will have something to do while waiting for bearings.

playing around with the thought of putting in a turbo along with the supercharger. Its easier in the truck. Also planning on removing a little material from the top of the pistons to lower compression a little. By my calculations its only needed to take away 9.5cc to lower compression down to 18:1, thinking that a "halfmoon" in the crown close to the other shape could be the way to go

 

[Stabben]

A little more progress. Dished the pistons 9cc total volume, this combined with the felpro thicker gaskets gets it down to 18:1 cr. If you look closely at the main bearings there you can see that i have drilled and fitted my own version of piston squirters. The 6.2d 599 block doesnt have those. Fairly similar to the original design. I use 0.8mm welding tips as a jet inside the holes. Press fitted.

 

[AlaskaBill]

What a great project, a lot of work!
Could you tell me about your super charger set up? Intake? Intercoolers? How much boost can you get and what temperature air enters the engine?
Thank you! Thinking it could be a good option for me.

Hi there, at the first engine in the van its an opcon/autorotor lysholm style 2.4liter.
Its supposed to be good for 22psi and even up to 26psi i read somewhere.
Before it gave up it was down to 11-13psi.
Was up on 16-18psi at first.
Thats with a little smaller pulley than the ordinary thats on a standard md300sc engine. After a closer look there must have been something wrong with it from the beginning.
Havent gotten a chance to test out my new 2.8liter yet.
I'm a bit back and forth on what car is getting which supercharger atm, thinking on putting the second 2.4liter in the van and the new 2.8 in the truck, but where i land with this in the end i dont even know myself yet.
Intake is from the hammerhead engine with built in intercooler that needs an heat exchanger, water pump ..
Intake temp at cruising was at 120-130f but could climb a little at hard pulls, but upgrading to a larger heat exchanger next time in hope that it will stick to 130f.

The 2.8 charger should give about 30psi, but if I will run it that hard i havent decided on yet.
There is also an challenge on getting high enough rpm on it with standard pulley on the crank.
The good news about this route is that you dont have to wait for the power and it never feels like its only halfway there.
At cruise and only a little up from idle it will give you 10psi and you dont touch the pedal much before its at full charge.
But if you're worried about the cost its a lot more wise to go the ordinary turbo route.

Finding an donor marine engine is the trick with forged crank etc ..

 

[AlaskaBill]

About the forged crank, I don’t think they are necessary unless maybe you are drag racing. The machine shop I use recommended that I use the stock crank, he has been building engines for race cars, trucks, and tractors for years. Diesels are lower rpm engines and build power and torque more gradually. Also, an automatic trans is also a smoother transition than a stick (manual). I broke one but it was because a main bearing web cracked and broke. I now have oversized splayed main bearing caps. So far so good!

 

[Stabben]

I'm no pro and i havent built engines for other than personal use, but I have read a lot about these and also on when marinediesel first started with these there was a lot of cranks broken and they firstly cut down from 2 or 300hrs oil change to 100hrs.
I'm not sure if I remember 100% correctly on this, but I think on the first versions they used cast cranks and then went over to forged in the end before the duramax marine replaced them.
Just think its better to be safe than sorry and when I first have them at hand its better to put them to use.
Marine engines were built to take 3200rpm constantly for hrs and thats why I wanted to use as much from it as possible to "bomb proof" it in a car that never will see that kind of abuse and even try to push it a little bit more than what they were as marine engines.

Guessing my blocks is what will crack first so I have a couple laying around for when the time comes.

Sticker tuning is important.
40hp+ easy instant gains!!

Any more pictures on piston squirters?

 

[Stabben]

Any more pictures on piston squirters?

I didnt take any more i see, but its a really simple design. If you look at the stock piston squirters in the blocks that have them thats how the holes are drilled.
Starting off with an smaller drill than final dimension to have something to pin the jets against when pressing them in.
I used mig welding tips as jets (0.8mm tips) those have larger holes than 0.8 and are more close to the original jets holes.
Used metric drills and if I remember correctly the 5 or 5.5mm was sligtly smaller than the tip itself so when fitting the tips i made a pin tool with rounded shape that fit nicely inside the back of the welding tips and a couple of light taps they were in place.

Used old bearings to mark up the positions and took my time to get the angles on the drill right.
I'm sure there is people out there that can make this better than what I did, but this works for me and can be done with everyday tools in my own garage.

 

[Keith_J]

OK, I see them now. I would prefer a design like current Duramax which only flow above 20 PSI. As oil pressure is a function of engine speed, this helps regulate piston temperature.
I'm thinking of such a system in the oil pan, using tubing. Have to figure out the plumbing as it has to be very reliable.

I like the system used by VWs.

Where did you buy those dished 18:1 pistons? Did you machine them yourself? How thick was that felpro head gaskets?

I made them myself.
.010 thicker.
Dont trust my design blindly.
This is more experimenting as I go along with this project.
Will post up results when its finished.
