The DS4 pumps are throttle by wire, and that requires computers, sensors, and other electronic things violative of the Pigpen charter.

I don't recall 100%, but I think you can just swap the DS4 for a DB2 mechanical pump. There will be a crank position sensor that would then be useless except to plug a hole.

Always hone. Get the oil pump from GM, and get one for a 99 6.5TD - high volume. I rebuild one side of my first 6.2L and reused the head bolts, which is a big no-no, but it ran great afterward. Reuse originals for pre-head rebuilt, and regular Fel Pro TTY for post head rebuild. Unless you're going to 300 hp and 550+ lb-ft, don't spend the coin on the ARP head studs. Fel Pro head gaskets are worth the extra money.

i think oliver just lurks on here waiting for diesel questions

Excelent info, thanks. The DB2 pumps are fairly expensive compared to a 6.2 pump right? Thanks for postin that Jerry but I think I'm just gonna rebuild a 6.2 since I have so many parts and am tired of constantly fixing an old ****ty motor. I am planning on getting my injectors and pump rebuilt by Kennedy diesel, they come prety well recomended on CK5.

Aren't high volume oil pumps intended to be used with "racing bearings" that have more clearance than normal ones and thus require more oil to be pumped through them? Do you have a part number for that pump you mention?

When ya get ready, give me a ring and I'll help.

I don't know if you realize this, but after it's all said and done and you've spent all that money on it... It's still a GM 6.2L diesel.

Just making sure you realize that... :flipoff2:

A 6.2 pump is a DB2...the electronic DS4 ones are the expensive type. High volume pump is just a bonus from later year 6.5s.

Now, if you'll excuse me, I have to get back to lurking.

So you can put the 6.2 pump on the 6.5? Is that the same one the 93s used?

I think yes, and yes. A 93 used a mechanical DB2 pump, just like all the 6.2s from previous years, but this one flowed a lot more fuel.

So, how much hp can the 6.2 pump support?

6, maybe 7

oops, forgot :flipoff3:

the reason I say this, I saw an uparmored hummer not be able to back up over a 4-5" curb today. They had to pull up and get a few foot running start at it....

thats why military hummers in the field are about to be extinct...id tell you what i know but i dont think the man would care for that much. we have two replacements...one for speed and one for grunt...the ones for speed will be removing afganistanian resistance some time soon :gigem: think bad ass rockcrawler/dune buggy...


EDIT: i can say this, oliver will be happy to know that the speed somes from a supercharged duramax or a regular turbo charged durmax...though the turbo is bigger...

The end of the hummer has been along time coming, it was not designed for the duties it is taking on now and they have hell with them. The stryker is slowly creeping in here, they are great vehicles from what the guys tell me. The cougars and buffalos are also well respected vehicles here, they take a lickin and keep the passangers relatively safe.

lets take this to your iraqi pictures thread...

I'm gonna go ahead and buy external tranny and engine oil coolers cause the built in ones in the factory radiator are a pain in the ass. I want ones that have mounting feet on them cause I dont really like the little plastic strips you poke throught the radiator and cooler, I know plenty of people use them and dont have any problems but they seem kinda janky to me. The mounting feet issue keeps my options prety limited as far as size goes, so I'm not too worried about that.

The only decision left is whether to go with stacked plate type coolers or tube and fin type. I like the stacked plate better because of durability but I have heard that they can have a problem with air bubbles getting trapped in them, which is bad juju for the tranny and engine. Here are a few that I like and are decent price-wise;

I like this one cause it comes with baller A/N stuff that would look way out of place on pigpen but its prety damn expensive.
