I need to do some work under the hood and am fishing for ideas. My situation is as.....ummm....er........eeeeeeee....unique as the rest of my life.
What I have, E99 with flashed PCM with what was suggested to be an 85HP tune, 4" exhaust, AIS intake, wastegate line stopped off, leaking up pipes. Currently AB sticks (they'll be addressed at a later date).

Also has this turbo wheel in it.



I have in stock a litany of parts from two acquisitions. What I am looking at assembling...

1) Melding this turbo wheel with my 2003 van turbo. I do not tow often but when I do I tow pretty heavy and I'm thinking that this should be a good match. I'm approaching geezer status so snappy low end is not a big thing with me. What would you recommend I do with the turbo? There appear to be no problems with either turbo except for chipped fins on the van turbo wheel, which I will be replacing. They are both as tight as could be.

2) Pedestal from that van engine which is either new or was rebuilt. Is that going to be the same pedestal as used on L99 and up F models? The van plenums are 3 1/2" OD (or so) I also have L99 engine with plenums if I need to use them. Those plenums are in the 3" diameter range. Should I go with the new pedestal? What all else will I need to change out when I do it? Do I need to swap out plenums? Bellowed up pipes for the later set up would be cheaper than E99 uppies and lead me to want to update that department.

3) 120V IDM out of 2003 van.

4) Update HPOP if this one is E99 model and update is worth it. I have an L99 HPOP with 250,000 miles or so and a rebuilt one out of that 2003 van. Which to use, if either?

5) That L99 engine has braided SS HPX hoses, van has things on it that look like garden hose and not sure what's on the truck (I'm slacking on this one). Which to use?

6) Inspect and rebuild fuel bowl if necessary from either van or L99 engine ahead of time so I can reduce down time. Any thoughts? What should I do to it?

If it's worthy of discussing right now I am investigating going with AC sticks when I do them depending on whether or not my AIS intake will handle it (flexible on this one) and what will have to be done to my flashed PCM. If none of these other things make a difference in considering the sticks we'll leave the sticks out of the mix for now.

That's all I can think of for now but that should get me started. Of course all of the above is subject to additions and/or corrections.

Thanks,
Mark

 

I like the upgrade to the Van Turbo. Rebuilding the fuel bowl is not difficult and is a good maintenance item. Look over those braided lines before attempting to install. Hopefully, they don't show any signs of wear from rubbing. I am still running my stock HPOP and have had no issues, but I am running a 2001 7.3 and only have 283,000 miles on it. You could do a plain pedestal and remove the wastegate valve. I may not have that right. Looks like you have a great project going there.

What, no additional input on the project? I know there is knowledge out there on what to do with the turbo, what all needs to be changed to upgrade to a later pedestal, should I change out that HPOP, etc.

Come on now, You know it takes the smart ones awhile to put down their slide rules and turn on the 'puters.....

 

Good things take time and require a little thought...had to get 'er back up on the radar screen.

Ooooh and Happy Father's Day, it is a big weekend holiday too.

 

Yup, took all next week off...Mental Health....


And Happy FD to you, I forgot to say, I have no input on the subject....I run a unlicensed Fusion Reactor that runs on Garbage, so I can't speak to Turbo's and such.

 

Change the HPOP for sure. Better to go to the T500. Spider and up pipes along with plemiums have to be changed to do the late pedestal and Van turbo. Do it right the first time.

 

I'd need a spider, eh? The van had no intercooler so the spider is different. I agree that things should be done right the first time and when I tear it apart I want to knock it out all at once. Which plenums would be used, the ones from the van with the 3 1/2" diameter or the L99 with the 3"? What is different from my E99 plenums?
Would a T500 HPOP be necessary? I was hoping that what I have would suffice.

 

That's the stock e99 wheel, don't waste your time on the later intake plenums because you will need the pedestal, turbo, and spider to make it work and in the end you will have the same turbo,the 1.0 exhaust housing wont let you spool quicker contrary it will take longer to build boost but on an upside your egts will be reduced a good amount. The only reason to change the plenums would be if your installing a custom tubo that will build over 40psi then install the riffraff billet plenums.

 

So sticking with the E99 pedestal will save me from switching out the plenums, will the van turbo swap right in? I would swap out the wheel into that turbo. I'm not horny for early boost but I like the idea of more air and lower EGT's when pulling north of Scranton grossing 18,000.

What is different about the plenums?

 

I think you can swap your e99 center cartridge and compressor housing into the van 1.0 exhaust housing, not 100% on that check the mod folder on the obs section and look for my mod "freakify mod" you can mismatch e99 late 99 and Obs turbo parts. Judging by some Google images the van turbo exhaust housing is the same so your e99 center cartridge, and crompressor housing will work, as long as you have the 1.0 exhaust turbine to go along with the exhaust housing.

 

The van turbo as I recall is 1.15, not 1.0. I had one and felt it was a smokey/laggy pig.

 

Dan might be right, haven't done any research on the van turbos. I like my 1.15 obs turbo once you put sticks and a good tune they spool rather quick, and towing egts are always cooler than the .84 housing.

 

It is an AR 1.15 and the exhaust wheel is there and appears to be intact. The PCM is tuned and I currently have the original AB sticks. I am in no hurry to replace the sticks but would go with AC's if my PCM can be tweaked to accept them without a major expense, otherwise I would just put AD's in. I'm pretty happy with the results of that tune.

 

If you can get the T4 collector try it, let's see if you like the 1.15, for towing the 1.15 are awsome, just remember the down pipe flange is smaller on the 1.15 than the .84 so you will need the flange and a v-band clamp from that van.
