I am in the middle of installing my 1.15 exhaust housing and found out while doing some reading I have to use the vans exhaust turbine.

Is this true what would happen if I ran the truck turbine?


Thanks

 

When I did my van turbo I rember the center section being the same for truck and van turbos. It should fit just like the .84 housing did.

 

But I think the exhaust turbines have different outer diameters

 

Bolt it up... its the same!

 

Just to clarify I am installing a van 1.15 with a truck turbine here we go I will get started

Thanks

 

Bolt it on... its the same...

 

The truck turbine wheel will fit in a van housing, but I think JTHarvey found that the van turbine wheel will not fit in a truck housing. Maybe he'll jump in and clarify.

 

wont he need an exhaust adapter to bolt up to his down pipe

 

If you are putting a Van exhaust housing, and not a 1.15 housing made for an F-series truck, then you will have some fitment issues. Nothing that will stop you from getting the job done and the turbo on the truck, however the wheel is somewhat (relatively speaking) smaller than the housing it fits into. May drastically lower your drive pressure/boost as the exhaust pressure would pass right over the wheel and through the gap.

 

That is what I am worried about I have everything else figured out but that

What happened was I bought all the parts to do a van turbo, but the van turbo I got had a smaller compressor housing on it. So I was going to use the turbo from the trucks comp housing and during disassemble found the van exhaust turbine to be damaged. It had been in contact with the housing though the housing is perfect.

 

Bump for more info so I can finish her up

 

Call Ron, he rebuilt my van turbo a while back. He is located in Utah, he may have a van turbine wheel. 801-842-9186. I highly recommend him.

 

They are different. I had both on the bench, side by side to test. I actually bought a used van turbo just to find out for myself. (Ended up using it though when my stock one puked.) Van housing will fit over the truck wheel, but the truck housing will not fit over the van wheel. It starts to hit right where the sharp points are on the curved edge of the wheel. Here are a couple threads I wrote up about it:

Unfortunately, you can't put just a turbine wheel on it. They are welded to the shaft, so you'd end up having to replace the whole shaft to just get the wheel. I could not find any place that sold the wheel/shaft assembly alone.

 

Well I ended up calling a local diesel shop that does turbo work and was told the turbines are the same (which they are not) but put it together anyway

Everything works

A bit laggy makes 25psi max where I could hit 28-30 before

But I can not get the EGTs to go over 1250 where before I could hit 1400+ if I wasnt watching it

Thanks

JT I am going to reread your posts and try to determine my best route

 

I too was told by many different people (expept for one guy) that the turbines were the same. I needed to know, if nothing else for my own sanity. So, I bought the van turbo so I could find out for myself. Those that tell you they are the same, obviously haven't checked for themselves.
