Re: Spartan part 2, Suburban build. New home for 6BT/VE
« Reply #1 on: November 06, 2018, 11:46:52 PM »
The good;

Starts easy, not to loud or much rattle, hardly any smoke. NO SMOG NEEDED, EVER!
Hydro brakes from the factory.
4L80 transmission, shifts good, all electrical seems to work, even the windows but they need rebuilding.
4inch Lift, 33in tires, 2 are OK but no cord showing
Barn Doors, no rust, glass all good


The bad?

Door dent is a little worse than it looks and actually goes from the front door to the rear panel a little.
Looks like a home made turbo setup and still not sure if its a 6.2 or 6.5
Exhaust goes down through the right fender liner, then back and under the frame to the stock muffler, sure its home made.
No 3rd row seat (but I have one) No headliner.
Has a newer style receiver welded under the stock and will need to be cut off.
Lines cut off for the AC and the rear unit removed.


The plan;

Finish up the original Sub with parts from this (lift, tires/wheels, bumpers) and flip it, so I loose no $$$ at all.

85 and it is a 4L80, so thinking it is a 6.5. Plus it has the vacuum pump below where the 6.2 was on top. Then again it has reg belts vs a serpentine system which says 6.2.

Working on ride to get it now, just an hour away.

That's pretty brave of you to drive it home... sure it starts and drives around the farm, but how does it handle on the road? Is it safe? Do you have access to a trailer?

Having someone follow and don't plan on breakneck speeds. Tires are OK too. May happen tonite,,,,,,,,

Yes, I have AAA+100 just in case!

You guts will love the turbo and air cleaner. I thought it had an intercooler at first.

Well, it did happen tonite.  :beercheers: Buddy ran me up, followed back as planned, just took way longer than planned.

Blew a little smoke for the first few miles. Most of the lights worked, 2 windows were open but the heater and radio worked good.

Wasn't sure of the fuel as it was blow 1/4, so I dropped in $50 which brought me up past half. Water light was blinking so hoping that would displace it enough.

So fuel gauge works, some of the dash lights. Oil is pegged out and voltage showed 12 but rose and fell with rpm so GTG.

It did 65 easy all the way and pulled good but is no dmax for sure. Thought it was dripping oil when we stopped for diner in Lincoln but stick showed full (black as you know what).

Dropped at moms house for now as no where to park it now. No oil was there when parked so it must have been from another vehicle.

What do we say about these 6.5's?

I was thinking they were OK. Relocate the PMD, bolt on a different turbo from a 6BT 12 valve, change up the exhaust and it starts to approach stock LB7 specs. For just plain moving peeps around in a burb, wouldn't that be pretty OK?

Actually, it moves around pretty well. No jerk you up torque, but it did 65 easy all the way home and moved well with foot pressure. It does have a little surge when driving, like the TC is unlocking.

It will get cleaned up and then a fluid change. I may address a few small things in the motor but the idea is a solid runner and clean ride.

Will clean up today and really see what motor I have so I can address the PMD and lift pump.

Moms back in the hospital so not much done.

Did find out the door locks work, well 3 of em. First thing is to get the windows working so I can lock it up.

Doesn't leak bad at all, yet. Need a boost gauge and figure out the system it has. Still wondering why the clamp is there?

That turbo setup is not stock, but I'm sure you know that

Someone coble some other turbo onto the side of the motor??? Necessitating running the exhaust through your tie rods, up and over the brake caliper and down the beltline trim on the door?

6.2's were

that changed with the 6.5

Not nearly as sophisticated as our present day D-Max

Old school very high compression ratio detroit diesel.

I have often wondered where that engine may end up with a significantly lowered compression ratio and 25-30 psi of boost with the fuelling to match?

The PMD controls the fuel solenoid. They mounted the critter in the valley on the pump!

The air cleaner on this looks like an intercooler at first. Turbo drain is running into the fuel pump block and comes off the turbo at about 45* angle vs on the bottom.

Hard to get good pictures when EVRYTHING is black.

Got everything for a fluid change today and found it has a swaybar disconnect.

Need to match up the black wheels and get a couple more tires. They will get swapped to spartan 1 for its sale.

Check out how they sealed the tires on the front. Now I need to figure what turbo I have.

Oh I am! None of the wiring is cut but the rear unit is gone. Need to add a dryer (cut line) and block the rear lines that are cut off in the cab.

The drivers side crosses over the the rear of the turbo side, then it all mixes and some goes to the turbo.

It is only pushing 10psi also. Some will see 12. The Banks manifold is nice but too pricey for this. If I was keeping the motor I would redo the system, stud the motor and have some fun. It runds good so going to add a few gauge and clean some stuff up is all. Been doing lots of reading, just glad I got the 100hp setup.

I that pic above it has the waste gate mode and no AC (probably a 90s truck.

Just uses a spring on the WG vs a vacuum canister and you can dump the belt drive pump for it as that is all it runs!

The vacuum pump should be for A/C, egr, and cruise stuff. The waste gate supposed to work off of intake pressure, not vacuum.

No EGR on this, but it does have a funny oil vent system pre-turbo. I do want the other items though so maybe it will not go. I kinda liked how they have it on the 6.2 though, cam driven.

Did an oil change, fuel filter and lots of additive today. Made a mess  :rolleyes: Lost prime to the motor (lift pump up top) and used pressure to get it going. I ordered a new lift pump for this from summit that is a pass through. Will run it with a relay also as stock they are driven via just a pressure switch.

New window moldings/felts ordered too. Bent a few lines to clear other things too, lots of little things I see to make it solid.

Need a real air cleaner I can carry over the 6BT also, this setup is a joke, but it only gets cold air. And look at the battery setup! Tested the Oil pressure sender and it seems to work, but I question the location both for it and the turbo oil. Traced the sender wire and it was only 3 inches long,,,,,,,,,,,,

Now the turbo feed is 45* rotated towards the firewall and the drain is 180 from that. Pretty sure that is not optimal at least for the drain. Looks like it can remedied but how critical is it? I may have to remove the turbo anyway for the air cleaner and intake leak.

Also noticed a chunk out of the balancer which I hear is common and bad news?

Found a wire on the engine top and hooked it up the oil pressure sender, worked great. Had over 40psi at idle.

While digging, found I have a 6.2, not an issue but still want to ID the block.

Put a pressure gauge on the intake, only 4psi so far. Should be 10-12, needs to be addressed for sure.

A 6.2 should have a place for a mechanical fuel pump to, if you wanted to get rid of that high mount electric thumper.
