exhaust housing adapter questions

[TjMiller]

Heres the story- I will be running a used 38r that I bought with a stock SD exhaust adapter. Will that work with a 4" down pipe? What is the difference between the stock SD adapter and a "van adapter"
Thanks-

4" down pipe will work
The van adapter is for the 1.15 exhaust housing I believe. Hopefully some else can expand on this

What do you mean by "adapter"? Are you talking about the the outlet that bolts to the turbine housing or the turbine housing itself? I thought the outlets were the same on the van and SD's. I know the turbine housings are different, but both housings should work with the 4" downpipe.

By adapter I mean the piece that bolts to the exhaust housing. I think I figured it out. The vans use the 1.15 ex. housing with no wastegate so if you switch housings you have to change the adapter also. Not sure if that's all there is to it?????

No....The adapter should swap over fine. I have the 1.15 housing on my 38r and it was the same outlet as the 1.0 housing that came on the 38r and stock turbo. The "adapter" gets moved over to the new turbo when you get a 38r new. I bought an outlet/"adapter" that eliminates the EBPV, but otherwise I would have used the factory outlet.

Ok so is a non-EBPV outlet better than an EBPV outlet with the butterfly removed?

Eh they're essentially the same thing, probably no noticeable difference

:whs: I can't imagine there is that much difference.

I just sold an 02 van turbo (1.15 housing,no wastegate) and the "adapter" only had 3 bolts that held it to the housing. Wastegated housings have like six bolts?? No?

 

[GreenF350]

I will look in a few hours when I get off work, but my 1.15 housing that is non-wastegated definitely accepted the same outlet adapter as my 1.0 wastegated housing and my stock .84. I still have my stocker in a box on the shelf and have the 1.15 on the truck so I should be able to settle this.

Well crap....I have to apologize and eat crow. My memory failed me. I looked on the truck, in fact I'm still at work, and the outlet is different. I didn't remember different options for the high flow outlet, but it is NOT the same as my 1.0 38r housing or the factory .84. Those match, but you were correct about the van outlet being different. I can't believe someone hasn't corrected me sooner. I generally don't post because I don't want to lead anyone astray, but I thought I was right. Hopefully I haven't caused you or anyone else to spend money based on that. My apologies guys. When I get home I will see if I can edit my earlier post so it won't confuse anyone searching for it.

Its all good man don't beat yourself up to bad lol
See if you can snap a pic of the 1.15 housing and post it up so we can see it

No worries. Anyway, what was your reason for changing the 1.0 housing in favor for the 1.15?

As requested. Maybe this will help with my redemption. Lol The first picture is the 1.15 housing, the second and third are the stock Super Duty .84 housing just from different angles. I know the .84 and 1.0 adapters are the same because I put my 1.0 turbine housing that came on my 38r on a buddies stock turbo and reused his outlet.


I actually have the stock downpipe on my 1.15 housing, so I see no reason why a 4" downpipe wouldn't work either.

Back when I did mine CSIPSD and others were saying the GT38R still exhibited compressor surge with the 1.0 A/R housing that it came with and didn't with the 1.15 housing. I was currently running with my wastegate on my stocker disconnected otherwise I couldn't get over about 20psi and my truck ran cooler EGTs and faster spoolup and higher psi. At the time not knowing too much about it, I went with it. The only regret I have is not keeping the 1.0 A/R housing to try it out, especially with some new dyno evidence to suggest that there may be more power to be had with the 1.0 housing (at least with a compressor wheel change anyway) and quicker spoolup. That being said, I never hear any surge, my EGT's are great, spool up time is fine and my exhaust back pressure seems to be reasonable, so I probably won't be trying out a 1.0 housing anytime soon.

I am building a van and wont have the luxury of an intercooler (for now)so was worried about the egts. Some suggested the 1.15, but I am curious to run the 1.0 and see what happens.

The van adapter looks like the high flow outlet from beans, but the vband flange is smaller where it bolts to the downpipe. So a van adapter will not connect to a superduty downpipe.

In that case if you want to use the van adapter then you would have to get a new downpipe? Green350 did you have to change downpipe or are you not running a "van adapter"? I guess he has a "high flow" outlet.

Another thing... I wont be able to find an exhaust kit for my van with a "SD" 38r outlet. Wonder if I can somehow make a SD exhaust kit work on the van?

If you get the 1.15 housing you can just use the van adapter and stock or aftermarket van downpipe. If you get the 1.0 which is wastegated, you will need to put a superduty flange on the downpipe. Maybe one of the manufacturers will let you special order that. Or get the turbo with a 1.0 housing, and trade me with some cash for my externally tial gated 1.15 housing. That would prob work better for me on a manual obs.

You can also put the 1.15 van housing on the 38r to get you by for a bit. It is not the correct housing as the van turbine wheel is bigger than the 38r/stock sd wheel. I ran my van like that for a while when I was getting the correct 38r housing ceramic coated.
