96 6.5 engine to replace 98 6.5 engine

[EscaladeDiesel]

I have found a relatively low mileage 6.5 N/A from a 1996 for a reasonable price. I want to put it in my 1998 Suburban 6.5 TD. Will this engine drop right in, bolt right up and operate without any modifications? Can I bolt on my turbo? Water pump? Will the injector pump and any other electronics work properly? THANKS

It should, assuming it was operating before...

Can I bolt on my turbo?
Yes
Water pump?
Yes
Will the injector pump and any other electronics work properly?
Sorry, I'm not gonna stick my head in that noose! (They should, though)

[EscaladeDiesel]

Thanks for the two yes's.....do I hear three <grin> I sure could use some good news for a change.

Does the 96 engine have a mechanical pump? If so, I don't think it will work.
Did you check the classifieds (http://www.thedieselpage.com/classad.htm)?
A guy is parting out a 1996 suburban that was rolled. Might be worth checking on the engine.

The only problem you will have with the 96 engine in your 98 truck is the oil cooler lines.

The 96 engine will have the small oil ports, whereas the 98 engine has the bigger oil cooler lines.(There is a slim possiblity that the engine might have the big ports with the small lines, my truck came with the small lines and the engine had big ports, I replaced the fittings and installed the big lines with the cooler)

Gm makes retro fit adaptors only if you install the newer engine into pre 97-96 vehicles, There are no GM adaptors to install an older engine into the 97 and up trucks.
To install the 96 engine in your truck you will need to use the small oil lines and change the oil cooler, everything else will bolt right up including the IP

[EscaladeDiesel]

OOPS I assumed it was an elec. IP, guess I need to check that out. I will have to call him tonight. I know it was from a truck w/ standard trans, and that the water pump on it now is not for the flat belt (as he called it) Does that info say anything other than its a 1996 engine? If its not an elec. IP can mine from the 98 be installed easily (or at all)? I will have to check on that on the oil-line port size. What is big and what is small, so that I can have them measured. I have some new lines that I purchased from GREG at Lube Specialist for the 98 wonder if they can be used on the 1996 engine if it has the smaller ports?

If it had a mechanical pump, it might not have anywhere for the crankshaft sensor. If it has v-belts, you would need to change the water pump too.

[JohnC]

What did this engine come out of? As far as i know, all civilian applications in '96 had electronic pumps.

Forgot about the oil cooler lines...

You might be able to re-tap the ports for the bigger fittings. [CAUTION! Not for the faint of heart - chips in oil galleries is a bad thing...] The early ones are pipe threads, IIRC. Or come up with yur "own" adapters. Talk to Greg at lubrication specialists. I know he researched the adapter scene extensively.

[EscaladeDiesel]

IT'S A MECHANICAL IP w/ no tps....now what???? can I put my pump on it without much trouble? Also, he says the lines are the quick-connect kind about 1" in diameter.

[tom.mcinerney]

Consider running the '96 NA as is. The mechanically injected rigs are very high reliability, no FSD probs. Less power, enough if not towing.
Don't know if transmission will work??

[whatnot]

If the engine is cheap enough then that might be the way to go. The turbo will bolt right on. (you would need to swap the intake manifold, exhaust manifolds, water pump, water crossover, flywheel/flexplate, some sensors and other misc. parts)
If you do some searches and/or a new post about converting to mechanical injection, you should be able to get an idea what it will take.

[EscaladeDiesel]

Mine is a:
1998 4x4 w/ the 4l80e transmission:

What will have to been done to get this 1996 engine w/ mechanical IP in my Sub. and have it running and driving?

1: Throtle pedal
2: Temp switch
3. Computer
4. Electrical connectors/connections
5: Other miscellaneous items

Since I am not doing the work I will have to see if the mechanic who is doing the swap is up to it. Thanks Again for all you help and advice.

Or strip the 'new' '96 down to long block; swap over '98 HB, crank pulley(refresh time cover seal),water pump, turbo oil feed, manifolds, FIPump, electric engine sensors, flexplate , accessories....and you've replaced anything that may have sufferred in the lost oil scenario. This asks the mechanic to only upgrade the block/heads; you needen't pay him to learn all the wire-harness/PCM modifications. Your electronics were OK on this rig, i think?

[G. Gearloose]

I'm still suspicous that its really a '96...

[markrinker]

I agree with Tom Mac 95's 'longblock' approach.

Recently used that method to swap a '97 into '94 truck. We did replace the '94 oil cooler with the larger '97 unit and went with new large lines to accomodate the oil spray block and higher volume pump.

Some minor clearancing was done to make accessories work with newer style intake and dual thermostat setup.

Much easier than trying to retrofit ECMs and harnesses for no performance increase, IMHO.

I am positive I read somewhere that a mechanical injection engine won't have anywhere for the crankshaft sensor. I think part of it might be on the crankshaft itself.
Maybe since it is a '96 it would have it anyway?
Is it out of a '96 vehicle or just a '96 engine?
The engine in my '93 is out of a step van and it had v-belts and a mechaical pump. It also has the large oil cooler fittings (506 block) so it was made '96 or later.

[EscaladeDiesel]

The engine is supposed to be from a 1996 Civilian truck.
Can anyone answer the crankcase sensor question?

Thanks,

Hi
I'm not positive,but it probly is a combination of,crank gear and a recess in the timing cover for the electronic senser.
When i switched to timing gears in my 6.2,their is a set for electronic pumps,called phazer gears.The crank gear has what i belive is a magnetic 8 pointed wheel on it.And i belive the crank senser goes into a hole in the cover and has o-rings to seal.
Not 100% on the senser,havn't actually seen one,but have seen the gears.
Good luck

The riskiest thing about buying something used is getting something that is not what it is claimed to be. I surely hope that this is not the case, but SO often it is...
