Ok I have some issues with my turbo I have a E99 truck. Now that I have been getting on it after the rebuild the EX wheel is rubbing on the housing inside. Obviously cause I have to resurface it so it would not leak(posted pics but did not get a response so I machined it). Here are my options. I have a VAN turbo as well. Now my turbo has a .84 EX and a 1.10 intake AR. My questions are.

Can I just slap on the EX shell from the van turbo?

What is the AR numbers for the van ? 1.0 intake I think but what is the EX side?

Would there be an advantage to the intake side as well? Maybe I should just rebuild the van turbo and run that complete?

Does the van have a odd mount I need to be aware of?

Thanks everyone I know this is alot of questions.

 

If I remember correctly the Van is a not wastegated 1.0AR thus the outlet is different than the SD equivalent. The intake I think is the same... (better check that info).

The mount is the same.

Riffraff has the outlet 1.0 A/R 1.15 A/R 3 Bolt 7.3L Turbo Outlet Adapter

 

Ok the Van turbo has a 1.15 EX and a 1.0 intake housing. And I think you were right on the WG thing, but how often do we pull the red line mod anyways.

Just trying to figure out with all these parts what would be the best combo.

 

The van turbo was a hot setup years ago due to the better drive pressure ratio from the larger turbine.

Its use fell off I think because the 38R has a 1.0, bigger shaft, bb cartridge etc. it's just an easier "better" swap.

I really think it depends on your intended use, injector size etc.

I go back and forth between a billet wheel rebuild, a 1.0 housing, billet wheel rebuild, and a 38R.

 

Cool thanks for the input and information. I think with all things considered I am going to use the 1.15 EX housing as mine is junk(pic below shows the bottom right corner up at 2 o clock it was not sealing on my .84 it was shooting all kinds of soot out. Along with a few other EX leaks at the up pipes). Then add my 1.10 intake with my Riff Raff 4/4 wheel. See how this all shakes down. I am hoping the reduced back-pressure of the 1.15 will make for reduced EX leaks in all points of the head to turbo system.

Like I said I ma in stock E99 mode here 4" ex and the RR 4/4 wheel are about the only things I have done.

You can not use a "truck" turbo shaft/turbine wheel with a van housing. The van turbine wheel is slightly larger. The "truck wheel will physically fit, but it will leave a gap, and will not perform right.

Use the complete van turbo, including the intake/compressor side. You can swap your RiffRaff wheel in though.
You will also need a late '99-'03 turbo pedestal to use the van turbo. You might as well get a blank (no EBPV), since the exhaust outlet adapter, which you also need, will not have provisions for it.

Or you could sell me the van turbo........

 

Oh, you'll also have to switch to a 99.5 and up "spider" and intake plenums, to use the van turbo.

 

Well I understand the Van turbo has the late model compressor side with 5 bolts and larger housing thus needs the late model pedestal to clear things with that larger intake/compressor 5 blt housing. The smaller E99 4blt fits more compact and am guessing maybe I can retain it with that side of things so it lines up. I was going to use the complete Van EX side and just use my early compressor side W Riff Raff wheel, so it would work with the E99 pedestal/mount.

I planed to retain the BPEV as it gets cold as hell here. The BPEV is there on the van turbo looks ok. looks like it will line up with the EX downpipe as before. The waste-gate I dont think I have to worry about 40 psi or a over boost situation and if I did I will deal with that when/if I get to it.

Does anyone see any issues with this ? I thank you for the previous input that was a big help I had not thought or know of alot of that.

Van EX turbine blades your right they are ALOT more spaced out and a tad bigger on the OD.

truck EX TUBINES much more compact and restrictive by the looks of it.

Van turbo in back truck in front from E99 the shell from the van is much bigger and wider

The early and late compressor housing and backing plate are interchangeable. Just pull it off of one and bolt it on to the other.

 

Thanks, I will keep you all posted on how this hybrid works out

 

Did you also check to see if the larger van exhaust housing, and related attachments (EBPV, etc..) will clear with the e99 pedestal?
E99 (complete turbo) VS late '99-'03 pedestal




Negative Ghost Rider, the plan is no good. The van turbo exhaust outlet will not fit your downpipe. The aftermarket adapters available, to the larger truck/Ex downpipe, are all "blanks". (no provision for EBPV). The only other option is to have some custom hokey welding done on the cast iron van turbo outlet (w/the flapper valve), to allow your larger downpipe to bolt up. By the time you pay someone to weld that up, you might as well just do a proper late 99 upgrade (with pedestal, plenum, spider, and up-pipes)

Yep. You're mixing and matching a larger exhaust side (van), with a smaller compressor side (e99). The larger van turbine will take longer to spool, vs the truck turbine. Your e99 compressor side will move less air (along with your restrictive e99 plenums, etc..) I predict a very "soggy"/laggy, smokey bottom end, and higher EGTs Perhaps you could spend some time calling the tech people at Garrett on Monday, and see what they say?

No they're not. The backing plate and outer "shell" are both lager on the '99.5-'03 Late is 5 bolts. Early is 4 bolts. The late uses a large o-ring between the halves.

Oh, also, "hotrodfeguy", I forgot I had it, but that e99 turbo pictured above is "available". Its complete, minus the wastegate actuator ( the spring loaded canister). Minimal side-to-side shaft play. None in and out. Its clean, turns smooth, and does not appear to have any EBPV leaks. Wastegate and EBPV are "free" and move like they should. You could run it as-is. But I would throw a quick rebuild kit in it( and your RR wheel) and call it good for a long time.

 

You're making mountains out of mole hills trying to look smart. Easy fix - cut off the flange from the van downpipe and weld it to the pickup downpipe. Easy as pie to do.


Once again, the internet rumor mill has people thinking that the Early 1999 turbo "moves" less air. Wrong. Also, the 2" plenum inlets are capable of more air flow than either bank can use at decent power levels.


You definitely missed the boat on this one. Pikachu is correct. The center cartridge is the same for all of the turbochargers mentioned in this thread. He said nothing about putting a 99.5 - up compressor cover on an E99 backing plate, but to put the E99 backing plate and cover on the later (or van) center section. Once again, you're making this out to be much more difficult than necessary. It's an easy thing to do.

 

Anything is possible with these factory turbos. Most of the components interchange, with the exception of the exhaust turbine. Heck mine has an e99 center cartridge with the obs 1.10 with an e99 pedestal.
