Thanks. We will see what it will do with a tune in it.

Some updates. I got the seat done. I redid the foam and wrapped it in canvas so it would not sink into the springs. I also painted the whole seat frame and made a new adjuster cable.

[marvgarr68]

More updates. I got the inner fender to fit around the exhaust on the right side. I also installed the EGT sensor in the down pipe.

[marvgarr68]

More updates. I installed the senders for boost and intake temp. I mounted the new wheels 15x8 car style chrome rallys. I made an oil cooler mount.

[jbclassix]

man, this thing is moving along! One of these days I need to take pictures of the 6.5 I've been working on................ It doesn't have the cool factor this truck does though

[marvgarr68]

If it's a 6.5 it's already cool.

So I found someone local finally selling a "running" 6.5 TD NV4500 (4x4)setup for a reasonable price. It is a 94 and he says is electronic injection. He said if I buy the combo then I can get what else I need off the truck that I will think I will need to swap it into my 88 GMC crew cab that I am converting to 4x4 and shortbed.

Any thoughts?

Don't use the electronics! That might have the odd child 94 pump that sucks. Use a 93 4911 mech pump and be done. I only buy 95+ 6.5's for that reason.

[NastyBuzzard]

I think I would prefer the electronics to be honest. What specific reason is there to not use them? I personally have never had any problems with a 95+ diesel. I don't get it.

94 has an odd ball pump and ECM. If you want it less problem the 4911 is the way to go. You get the pump, throttle bracket, and order a cable for a 88 with a 6.2 and done. The motor mounts the same way. Radiator, hoses, oil lines all for a 6.2. The a/c you will have to make custom lines due to different compressor.

If you go electronic who are you having tune it?

That is interesting news. How would it need to be tuned and why would it? I can use tunerpro and all that, but I have never done a diesel. I don't plan to do anything to it, just leave it stock. I have efi live but it is for obdII only I assume.

That is good news about the 6.2 stuff. I am not against going against purely mechanical but I don't have any of the stuff for it. All the electronic stuff will be coming with this engine.

If you had a 95 I would say maybe go with it. For what you want I don't think stock is worth it. A small block would be better even the tbi motor is better. As for tuning here is where that 94 pump sucks. I also thought the guy took the pump anyway? If you need to get a pump anyway then might as well go mech and turn the screw 1/4 and have a nice rig. If you buy an elec pump you will need a 95 pump and a 95 ECM to get good tuning. I am doing the same swap right now except its in a 77 square body and am using a 95 6.5. I got all the electronics with the motor and the whole harness. I am still going to use the 4911 pump I have and go mech.

Yeah I will need to find a IP. I have a guy at work that has 2-95 6.5 setups and wiring and ecms but only one IP. I could get it from him. I guess it will depend on when I am ready to get the IP what I can find for a reasonable price.

Why would the pre-95 electric make less power? I am sorry I am trying to learn about diesels.

It is not just pre 95. I should have been more clear. The F code 6.5 is what I was referring to. You have to make sure what you are getting just because it is a 95 or 94 doesn't mean anything. It all goes off the vin code. When I said I only buy 95's I meant 95 F codes. F code is non EGR heavy duty 190HP L65. S code is EGR CAT light duty 180HP L56. P code is van or hummer center mount turbo and 215 in military vehicles.

It is unlikely you have a P code.

You have to make sure you get the right pump with the right ECM per code.

I just don't see what you are trying to do really I might be missing something. I only went electronic because I wanted to get max power out of it not leave it stock. If I was going to leave it stock or even a mild boost I would have went mechanical like I was going to do. You want reliable and stock that all goes with mech. I still need to do some more tuning but I will be hoping for 300HP to the wheels when I am done.

Don't think I am trying to sway you any which way. I am just trying to help from my own experiences.

[NastyBuzzard]

Hey I am loving the advice!

I would hate to kill any power gains though just because I went mechanical. Cost is really driving the stock aspect at the moment. However, it is very possible I would want to try and squeeze out some extra in the future. I will have to check the VIN code to see what it is specifically. I had forgotten all about that.

I just don't feel like I have the option to go pure mechanical b/c I wont have the stuff for it and it won't be easy to find locally or for a decent price.

That is what I have been trying to say. It is cheaper to go mechanical. It is cheaper to get power gains going mechanical. You can urn it up or down with just a 5/32 allen key.

All you need is the pump and they are cheaper then a DS4 pump.

Mechanical list
Pump
Inj lines
Throttle bracket
Throttle cable
all junkyard parts

Electronic list
Pump
Inj lines
PMD
ECM
Harness
Throttle pedal
Sensors IAT,MAP,ECT,BARO,CKP
Boost control solenoid
New prom whether going up or down. $$$
Most of this you have but might not be good. Might go out down the road. This is where the reliability comes in. The throttle pedal alone is $600.00.

The last mech pump I bought with inj lines and throttle bracket was $30.00 from the junk yard.

I would search for a mech pump first see what you can find. If all the ones you find are expensive then go electronic.

[marvgarr68]

Update. I finished exhaust ceramic coated and wrapped. Installed the gauges boost, pyro, fuel pressure, and tach. I also have oil temp and intake temp but still need to mount them. I got door panels installed. I installed cruise control turn signal lever and new turn signal switch. I installed the VSS and worked last minute bugs out of the computer. Put a tune in it 50% more fuel and recurved timing maps and cold start reworked. I installed all new glow plugs. Painted and installed inner fenders. Reworked the intercooler lines and powder coated them. Got the ECM to read the VSS and with a couple of part swaps got it to read exactly the same as GPS mph. I also installed oil cooler and made new lines.

Great work! Your piping looks very nice. I know that cruise will be extra nice too!

[marvgarr68]

Thanks. Yea I wanted cruise control on those long trips.

[NastyBuzzard]

Looking good! I am supposed to go check out a 95 6.5 TD today. The last one fell through. This one is the Vin F model and is supposed to have 20k on a rebuild and an upgraded turbo. We will see I guess.

Nice! If your go electronic that would be the one to get.
