Do the Excursions use a smaller turbo than the F250s?


Thanks,

 

No to my knowledge. The vans have a different turbo because they don't have an intercooler.

 

To my knowledge, the Excursions have the same turbo as the 250s. The only one that is different is the Van Turbo.

 

Yep Excursions have the same turbos as all the other 7.3 except for the vans.

 

Thanks. For some reason My dad thought his Ex turbo is smaller than what was on his old F250.

 

I've always wondered why the vans had a larger turbo in them... now I know!!

 

what happens if you put a turbo off a van on an intercooled 7.3?

 

When you say "old" F-250, what year? If it's a 94.5-97 Powerstroke, then yes, those have a bigger turbo (actually a bigger turbine housing) than the Superduties and Excursions. Just like the vans, the OBS trucks don't have an intercooler, and have a larger exhaust housing than what the newer ones have.

 

You get a turbo that can handle a bit more boost on the top end, but will have more turbo lag on the bottom end.

People with chipped trucks or even with mild injectors like to go with the van turbo because it's super cheap, and it can handle the bit of extra power without blowing up or causing excessive EGT's.

 

Unless your Dad has an early 99 or OBS truck all the turbos are the same.

I would love to find me a good van turbo and have Jody give me a little more fueling down low to clean up the lag like Bdrummonds did when his was live tuned.

 

your truck will grow green and gold **** carpet inside ...

(sorry couldn't resist)

 

Excuse me! Thats avacado and harvest gold thank you!

 

+1.

a little off subject but hopefully not too bad, is the van turbo the same as the 88mm garret turbo gtp38r, if i go to the salvage yards is there anything on the turbo to distinguise a van turbo from a truck turbo.

 

The 38r has BB instead of bushings in it, and I believe a bigger inducer as well. It will support boost levels over 40psi, where I wouldn't run the van turbo over 35ish. The van turbo is just the stock turbo with a non-wastegated 1.15 A/R Exh housing. You can get near-van-turbo performance by picking up a 1.0 A/R Exh housing (with or without the wastegate) and slapping it on your stock turbo.

I just went through the exercise of rebuilding and installing the van turbo on my truck last month, and it's definitely a winner!! REALLY wakes up the top end of these trucks! Before, the stock .84 A/R exhaust housing spooled really fast, but petered out up top and caused super-high EGTs. Now the truck just wants to keep on going up there, and if it wasn't for the stock sticks sucking the oil out of the HPOP, it would be even better (hense the reason for getting different sticks to match up better with the bigger turbo).

I would say that the easiest way to tell if it's a van turbo is to pull it off a van! Not being a smart-*** here, but I seriously doubt anyone that went through the trouble of putting a van turbo on would let it go to a bone yard to rot! And you can tell by looking at the exh housing -- it will not have a wastegate. That's the most obvious difference between the two.

Here is a LINK to the album I made of my van turbo rebuild experience. It's super-easy, and you can find the turbos on eBay from time to time. Some folks get it for cheap (like around $100), I got mine for $203, added the rebuild kit, non-EBPV pedestal, and outlet adapter, for just under $300, and now I have the ATS ready to go on (another $400). So I've got a pretty decent turbo now for roughly $900. Plain old stock rebuilds are going for around $750, "super-turbos" (as Ron calls them on his site) are around $1200, and it's pretty much just what I have. Actually, less. Those have a wastegated 1.0 housing.

Hope this helps -- sorry for the book. Happy New Year!!
