Also found an easy way to take out the tamper proof screw. Use a sharp chisel and come straight down on it and make it into a screw that uses a straight screw driver.

 

Yes, that's the way I usually do it. I bought a small chisel just for that.

 

Hello, new to the forum. Great thread. I have a 1987 s1900 with a 180hp DT466. I am making a hot rod hauler out of it, and I am looking for 300+hp. I have been researching performance mods a fair bit, and have the following notes/questions:

1. MW pump - I reviewed the Dales's videos for pump mods, they are great. I am a bit unclear as to how far the quick adjustments can get me. If I send the pump away to a shop to complete turn-up and minor mods, how far can they take it? Can you flow 180cc out of it? Are the internals of my 180hp MW any different than those of a 250hp MW? I called a couple of pulling shops, and they can re-barrel an MW with bigger barrels, but that's in the $3000+ range.

2. Turbo's - My DT has a little Garrett with a T4 flange as far as I can tell. This thread notes the following options: Garret from a NGD 466/530, or the "E" series. Do all these Garret turbos have the same flange? I know the hx40 often has the t3 flange, but can be adapted but I would like to avoid the extra adaptor. There is also a Borg-Warner s362g - is this flange compatible?

I am not as worried about the inlet/outlet piping, as I will be doing an air to air, so all the piping will have to change anyway. I just want to find the turbo that's fairly common that mounts to the existing exhaust manifold. I am willing to purchase new or used here.

3. Injectors - Would my injectors work with the flow from a 300hp pump? We're the 250hp 466 injectors from the MW pump era the same, or we're there differences.

I know the other option would be to strip a 466NGD motor of its p-pump, driver gear and adapter plate, injectors and lines, and turbo - but finding scrap motors in my area is not easy - everyone wants to sell me a complete running take out for $3000+.

Sorry for the massive amount of questions (and it being my first time post here), but there is a lot of 466 info out in cyberspace, but not as much for the MW pump motors.

 

The first problem is you dont have a picture of the truck. We always like to see pix of good rides.
#1, the video doesnt show the actual fuel rate, it shows the screw at the top. See image below. Back out the nuts til the end of the threads. That gives around 19mm of rack travel, and roughly 180cc.
There are differences internally, but the biggest plungers it got was 10mm. You may want to double check your pump number. Other than that, I believe the cam is the main difference between the 2 ratings.
#2, turbos.... stock higher hp 466E/530 turbo is a GT40 and a T4 mount. The S362 is a replacement for a GT40, and also T4. The HX40 off of a Cummins 6CT will also have a T4.
#3, injectors. Stock ones wont get to 300hp without a lot of help from pump work. There are a slew of different ones for almost every rating.
For the P-pump, you would need the adapter & gear for an older 466 like yours, not the factory NGD adapter.

I tried to attach a picture - hopefully it worked. It's a work in progress. Plan is to shorten the frame by about 5' and mount a cab and hood from a 1960's F600 on the truck - I have the cab and hood already - it seems like it will fit the general dimensions reasonable well. I was going to just throw the DT in the ford cab and chassis, but the running gear on the IH was so superior/modern (it's got the hydraulic disks on it, and a decently fast 2 speed rear end). The only strange thing about that s1900 is how high the rad is - it's like a 14" higher than the motor - going to make hood clearance a challenge unless I get creative.

So to be clear on the S362 would bolt up to my existing manifold? I am not too worried about specific orientation of the turbos, as I am working with a blank slate pretty much at this point..

At 180cc, I am looking at 330ish-hp if can get it enough cool air? What rpm is 180cc at?

 

That's a great body style.
If that IH radiator doesnt work, at least you can run the measurements and find one at a wrecking yard that's real close.
Yes, the S362 will bolt up, if it's the replacement for a DT466E/530. The Dodge ones you find online wont fit. The chart I have at home says 180cc at 2600rpm(breakover rpm). With 180cc, it should be able to do 300-330hp, if the injectors can deliver that kind of flow.

 

Sorry about all the questions - I am also looking into a p-pump conversion as an option.

I have calls into a few of the local wreckers to keep an eye out for p3000 pumps from unusable core motors that come in. It sounds like the big pulling supply shops have adapters for p3000 pumps (as well as the 7100 pumps).

A p3000 adaptor kit looks do-able for maybe under $1,000. The issue becomes finding pre-bent injection lines. This pump never was installed in this location on a dt466 as far as I know. Can these shops build custom lines without the combo infront of them? I have heard that bending them yourself is not a good way to go (I can see how it would be very difficult).

 

I am in the same "add power" boat, but my 466 is going in my hot rod. Will post pics soon.
Ran into a sticking point though. I have a '91 DT466c motor and a AT545 trans. I have the 466 to AT 545 adapter plate. Problem, my torque converter seems to be too small to bolt to the flex plate. Do I need a new TC or Flexplate (or both)? Part numbers would be AWESOME if you got em!

 

How do you think a s464 would work? I have one from a second gen swap I did on my 2008 5500 ram.

 

It will, but you may need more fuel to put it to use.
