what type of turbo to choose?

The plate with the angle iron is a guide for the bit to cut at the correct angle into the block. The pictures don't show the camshaft, lifters, pushrods,etc. on the table next to it. Also the van exhaust and gm6
really chokes it compared to truck design.

Have you considered custom 4" Exhaust to a remote mount turbo? Look at thread from TurboVanman. I almost had a turbo mounted above my roof rack / rollbar. Kinda wishing I had done that instead. Couple of guys here have 6.2 &6.5 with hxII and they are way better.

See center turbo components that have to change if turbo height changes? Buddy of mine broke his housing after 15000 miles from spacing it up, oil on hot exhaust = fire. Full coverage insurance got him a nice down payment on a d-max.

Note the stock location and type of ops, later relocated to the extension hose coming up from the intake are. Wish I knew Leroy made one that carried the ground-ugg!
I hope this helps. Many other ?s

Excellent!
Sorry, my English is not so good. I can't understand some words. And even Google can't to help me. Tell me please, what is gm6 and hxII?
Tell me please, the oil inlet hole should be done at an angle. How to find the angle? I like your work! Of course, I don't really want to disassemble the engine, because it works good. But your way is the right. Help me pls with the angle of hole.
 
I cant tell you about the angle Will will have to tell you.
The gm6 and hxII are Turbo's
 
No good. If you raise the height of the turbo, it will not fit into the center piece of the intake manifold. Also the up pipes will not fit. Also the mounts are easy to crack if it is not a true and secure base.

On the pics, I found a few shots on my iPhone, how do I post them from the phone?
I understand you. What do you say about podium like this?image.jpg
 
That would work but you have to do the following:
Modify the up pipes -from the exhaust manifolds to the turbo
Modify the center piece of the intake manifold, with the turbo sitting higher you will need to add spacers and extra gaskets to the each side of the intake manifold.
Ensure the meeting surfaces are perfectly flat, and mail out the recess where the factory O-ring style seal will work.


The GM-6 is the turbo from General Motors that will work in that location. Factory turbo on vans and Hummers. It is a good turbo up to 2400 RPM, from 2400 RPM 2800 RPM it operates poorly, above 2800 RPM it is total garbage.

More pics coming asap
 
Thank you Will, you helped me a lot. And what about the angle drilling? I understand that the hole must do, connected to the channel OPS.
I'll think about what type of turbine installation choose. :coal:
 
One more idea! Central-mount turbo, manifold from 6,2 and instead of the air filter put intercooler. What do you say?

The drawing looks good.
Like Will said though, if you raise the turbo it will not fit under the 3 piece intake manifold and will require alot of other modification.
Your 3 piece intake manifold will not bolt up to the truck engine anyway (without machine work).
Depending on what you are using the truck for you might consider not using a turbo at all and naturally asperating the engine.
Otherwise I would make my own intake manifold using the parts you have and going with a turbo mounted wherever you want it.
Do you have someone you know that can weld cast aluminium?
 
He has heads, turbo and manifolds (intake and exhaust i assume) from a van.

Have you considered non turbo? At least until you can find/afford the other parts from a truck? If you really need the power due to loads being towed etc., i would look at propane for the extra power for now, then you can just flip a switch when you need the power and not have to go through this work and $ right now.
Long term you will be much happier with truck turbo, trust me.

Yes, Will and you are rite. If I'll raise the turbo it will not fit under the 3 piece intake manifold and will require alot of other modification.
The diesel should be good to breathe and the turbo is needed for this, IMHO. Maybe I'll make my own intake manifold, or put a stock. But I don't think than turbo must be somewhere far away from the engine. Oil drain tube should be as vertical. Yes, I have a friend that can weld aluminum.

Will, I trust you, truck with turbo much better. I don't considered diesel w/o turbo. I know little about propane for diesel. But the diesel bad breath w/o turbo. Propane w/o turbo is garbage, IMHO. Will the engine broke after propane?
 
No, adding a little propane helps burn the diesel fuel completely, and adds power due to the lower flash point. To much is bad. The turbo on any diesel is always a good idea, however when gm designed these turbos they were designed for low performance levels. None of the gm turbos flow well on the exhaust side, and are slightly undersized.

Each turbo has its own characteristics. The gm-6 is too restrictive on exhaust causing higher egt which rob power, efficiency, and causes higher ect's.. The intake side of the turbo is to small meaning the pressure has to go up more to get the desired increase of volume at too high a ratio. Simply there are better turbos available for this engine- unless you set up for the van turbo. Side mounting opens many options.

As far as turbo minted farther downstream, what is better:
Turbo mounted close that performs to 70% of engine capacity.
Turbo that looses 10% of its capability to pull out 90% of the engine capacity.

I did not try fitting the gm-6 turbo with the truck manifold, but thought about it. Coming out of the turbo to inter cooler, back to intake. The truck intake definately flows better than van. Then with your pedestal mount no drilling the block. Hose connections to turbo means no intake problems and no need to swap heads. The only difficulty is rework intake tube to turbo and up pipes.

I think this is the better idea for me!
Fit under the hood of my Suburban such a system?
 
I would use a generic turbo, van up pipes and still do a centermount setup, then you avoid using the stock crappy turbo unless your looking for a bit more power and not going hog wild.

Unfortunately I did not found the info about generic turbo. And I understood bad what you wrote. My English is bad :rolleyes5:. I think that power of crappy stock turbo will be enough for me. I don't want to be hot wild. ;)
I saw your project. You put the turbine under the body. Good job! May be I don't know much, but I think it's not a very good mount. There turbine will has bad circulation of oil. Or I'm wrong?

Your english is pretty good, :thumbsup:

Generic turbo, IE Holset HX35/40 or an HX40, ATT, something like that.

A stock setup will get you around 180 hp, maybe at the wheels turned up, someone else can chime in about that.

Thanks, and yes, I have a recirculation pump to route the oil back into the engine. This Feb will be its 1 year anniversary. , :eek:

Thanks for the compliment! Can you tell me about recirculation pump pls?
