i know we have gone though this conversation before with other people.... but i think im gonna give it a shot and see how it goes. got a chance to get a psd turbo off a 01 f250. im gonna try and get my hands on it and see about making it work. id like to get 12psi out of my system, but im getting hardly anything with the intercooler. it just takes so much to bring all that volume up to a respectable psi.

Hope you have better luck than some have. I have been thinking of plumming up my own system. With this 4" lift there is a lotta room back there now. I could even put it above the bellhousing and still not hit the body lol.

I can tell you it will not bolt up to the up pipe and it also will not work with the intake hat you have now.
Check the A/R numbers on the turbo.
I know my 97 has a 1.10 A/R.
I can't remember if the one on my 6.9 is a .72 or .85 A/R since I have both.
Lower A/R, spool sooner with less high RPM boost potential.
Higher A/R, spool slower with more high RPM boost potential.
I went with the lower A/R, since I try not to run mine at 3000+ RPM for extended amounts of time, fuel mileage just goes to the basement if I do.
The extra volume of the intercooler and tubes would have the turbo lag factor increased a good bit, but the numbers should not drop more than a PSI or two after it spools.
Sounds like you may have either an exhaust leak or a boost leak in your system somewhere.
3" down pipe, header wrap on the cross over and up pipe to keep the exhaust hot.
I have no problems getting 20+ PSI boost with my ATS.
Also the fuel level you have from the IP and injectors does play a part in how much boost you get.
I have engough fuel that if I put my foot down hard with boost numbers over 20 PSI, I can still roll the black out of the stacks.
Ram air hooked up with temps in the -20 range is the only time I have a hard time rolling black.
But the truck sure does run good when the temps are that low.
On a side note, my son is looking to make something like the exhaust plumbing that a 7.3 Stroke uses on his 87 6.9 so he can eliminate the cross over pipe.
As you can see, there is a lot of difference from the IDI setup on the exhaust side.
The ATS downpipe is exactly where the Stroke up pipe from the passenger side manifold is.
On the Stroke downpipe, it goes just outside the passenger side up pipe to the turbo, almost at the rocker cover to head connection in that picture.
Hard place to get 3+" of clearance on an IDI motor.
You will also have an exhaust back pressure valve to deal with, but you can just gut it and block off the shaft ports.

i know that nothing is going to bolt up, but i would custom make everything. the intake hat should be fine since im running an intercooler instead of turbo straight to motor. i would im sure change it though since id want to go larger pipe. im only running 2" so the turbo lag wouldnt be so bad. i do want to turn the fuel up, i get 0 black smoke, even with 12k behind me. i wouldnt even know where to start to find a boost/exhaust leak. there is so much goin on and its not as easy as finding a vacuum leak to track down. and as far as the 3" downpipe... im waiting. damn ats still hasnt come though with them.

Dave I asked this once before but can't remeber if you had any input onit. I had the chance to get a couple turbos off of volvo 940's. I think they are the same as garret T3's. They are supposed to put out a max of 16psi. Would these work with our engines? Run one off each manifold feeding a common intake hat. Would they spool to fast and have nothing on the top end?

Figure the Volvo engine displacement and max RPM, then figure the IDI displacement and RPM to get base flow numbers would be where I would start with something like that.
Something tells me, given the Volvo engine RPM at a guess that one bank on the IDI would not be enough to spool the turbo.
What is the engine displacement and what RPM is a Volvo is capable of?

These are the specs on a 94 940. 2.3L inline 4, 8.7:1 compression ratio, 162hp@ 4800rpms, 195 f lbs torque@3450 rpms. Hope this helps.

being that they are garett based you could swap the exaust side of IDI turbos onto the volvo ones Then you should be able to spool them but then again the the intakes may not push enough volume for the IDI I don't know. Of cours you could run one of the volvos sequential with the IDI using the smaller of the two to spool the larger but I would need to know way more about the turbos to know if it could work.

ok back to Oreo who seems to have been deprived of attention, you may also be able to run a squential set up useing the stroke turbo, after you fix what ever problem it apears you are having causining your low boost sounds like a fule problem if you snap the throtle, siting at idle in neutral floor it let it come up to about 2500RPM you should see a decent puff of black smoke if not you are way short on fule for a turbo. If you are getting good smoke then an exaust leak is easy to find have some one reve your truck like described above and look for smoke coming out of the exaust befor the turbo.

i know the above pic is of a psd but if im not mistaken doesnt the pulse turbo set up for the idi look very similar to that? IIRC the exaust manifold up pipes come up around the bell housing into the turbo
it is almost identicle Hypermax drsigned that set up for IH for the T444E and is also what they use in there kits for the IDI

If you're custom fabricating everything, why not just custom fabricate a 3" down-pipe? Why is ATS taking forever? Do they not make them? Search for EBPV delete mod in the '99-'03 PSD forum for ideas for that.
Can you run a 12V or 24V Cummins turbo (not sure they're different) on these IDI's? I saw a complete Cummins turbo setup for $300 on CL the other day.

Where you have to be careful when you start changing turbo's around is the IDI max boost.
If I wanted a reliable motor, 10 to 12 PSI on a 6.9 or 15 on a 7.3 is about as far as you dare go.
Yes it may take more, but you will be changing head gaskets a lot sooner than you want to.
Remember the Strokes and Cummins engines are running stock compression ratios in the 17 or 18 to 1 range.
So they can take more boost than an IDI can even think about.
Slap that turbo on an IDI running 21.5 or 22.5 to 1 and you start getting extreme cylinder pressures.
Take a Stroke at 18 to 1 and run 20 PSI boost to it.
The total effective compression ratio is 42.4 to 1.
Take a 6.9 with a 22.5 to 1 compression ratio and put the same 20 PSI boost to it.
Now you are looking at 53.1 to 1.
A 7.3 with 21.5 to 1 and 20 PSI boost.
Drops the compression ratio to 50.7 to 1.
If I remember right the Cummins is about 17 to 1, so 20 PSI gives it even less than the Stroke motor.
Head studs will keep you rather reliable up to about 20 PSI on an IDI engine.
If you want to go higher, mill the pistons and run head studs.
