I'm gettin ready to pull the motor out of my truck and rebuild it. Planning on a DPS pump and injectors, the "typ4 cam" if i could find out how to get it, propane, head studs, either a sidewinder or ats setup turbo, BD performance torque converter, and maybe a water/meth and head port+polish. Just wonderin if anyone else has done any rebuilds or any upgrades i'm plannin on. Just wantin to get some advice in advance. Thanks.
I'm looking for the information that you are about a rebuild. I recently replaced the motor in my truck that dropped a valve that ended up cracking both the head and the block. The valve retainer wore and broke free due lack of oil from a blockage I wasn't aware of.
Anyways.........
Replaced the motor with another out of a 92' F350, and I put my Banks Turbo on it. Everything seemed fine, but now it looks I've blown a head gasket on the replacement motor (due to the turbo maybe??) I'd like some advice about what it takes (money & time wise) to do a total rebuild. It would be my first rebuild, but I'm up for the challenge. I'd have more confidence in a motor I rebuilt versus just replacing it again with an unknown motor.

I recall water meth kit being a better option then propane, cheaper to windshield fluid pretty cheap. Also make sure to get the crankshaft ballanced, from what I heard they can be pretty far off.? Is it a 7.3l? If so what year? Some of the internals of the 93-94idit had stronger parts.
It's a 94 7.3idi turbo. And this will be my first mainly solo rebuild, first ever on a diesel. I've done multiple rebuilds of old cleveland motors and some windsors with my dad so i know the basics. And the windshield washer fluid, a buddy jsut told me about that when i told him what i was gonna do. I was gonna do both water meth and propane prob cause the propane will cool egt's a small amount but it will give it more kick in the pants on takeoff plus towing and a lil fuel mileage as well. The water meth would be more to keep it cooled off and less about the power. Either way, i don't wanna put money into somethin like this and burn 'er down.lol
Hopefully s*** doesn't hit the fan with that post..like it would on another forum.....
But yep a lot of good new stuff you will find there
I hear ya there man... I'm sure there are a few here from over there but the builds were talked about over there also. I just want more people to know what NMB2 and Racin are doin for our engines. I wouldn't have brought it over here if everyone over there hadn't already know where to go due to the fact that I don't want people to ruin those build threads. But overall, most people are being pretty respectful and letting them do their thing.

I agree with that, I just hope they can do there thing with out people tryin to bring em down. I'm really excited to see where this could take the idi world!

For sure man. I have supported what they have been doing all along as well as I know you have. I just can't wait for them to be finished already. I wanna see the dyno results and videos as they prove all the naysayers wrong. The engines also need to last so that nobody is able to say I told you so but I'm pretty positive they will do just fine.

I think they will last too, from talking to them it seems they did tons of research and put a lot of thought into the builds. For example when I'm on the phone with one of them they can talk to me for an hour on stuff that I had absolutly no clue about. He was telling me his plan on keeping the zf5 cool and it was a pretty genuis idea. They know their stuff, I'm confident that their builds will do just fine! And if not then..that also just adds to the idi knowlege of what will and won't work
I read through both threads last night and today, interesting in a lot of ways. Definitely some 'out of the box' thinking. I hope both builds turn out well.
I've been doing some reading on everything I can find on our DB2 pumps, as well as the DB4\s, and had been wondering if a DB2/4 hybrid was a possibility, apparently it is. It was on my to do list to tear into a DB2 this winter and see what I could figure out. I have learned that there are different piston sizes available for the DB2 as well, and am curious what size pistons are in our pumps, if they are all the same, or if they change due to year, turbo etc.

Ya those builds are really awesome and I really appreciate what they are doing. And as far as the DB2 pumps go, iirc the turbo pumps have bigger pistons the non-turbo pumps. But for the most part, I am not sure how much of the problem with making power with these engines is the injection pump per say. There are many people running the Moose Pump and DPS pumps and most aren't able to use up all the fuel that even they provide. IMHO we need to start with the turbos and make 20+ psi of cool boost and then go from there. I believe that if we do that it will be easy to make 300 hp and 550lb-ft. That is essentially what RacinNdrummin is doing plus a lil more and NMB2 is really pushing the envelope and is aiming a lot higher. It will be awesome to see what they do!
N/A pumps are .28 sized plungers and turbo pumps are .31. You can fit a .375 plunger into the DB2 but makes it a really shaky unit, putting lots of stress on the drive shaft. The way to tell what plunger size is in the pump is to find where it says XX28 or XX31, ect.
My DB4 uses .31 plungers. Also, turbo pumps use torque screws which are useful if you have an engine that can benefit from it, I lost/gained 30-35hp ajusting that screw on a dyno tune.

That is some good info. They can also fit the DB4 head on a DB2 iirc also. That adds some fuel too. Also, what did your truck dyno at?
