Which one is this?

 

If there is a way of measuring this, how do I do it? I can't figure out that part.

 

That is not an Evo housing.

 

WTF....Haha. It is an evo housing. Just not sure if its a 9.8 or 10.5cm turboine housing

 

9.8cm2. ALL 10.5cm have the single flap wastegate

 

Some early 10.5 have the dual I know. Just not sure which this is. It is supposed to be a 05 model but there is no coding on the turbine side for it. The compressor side says 9.8t. I am wanting to verify 100% before I order another housing

 

haha why do you say that?

 

Someone on here has to know?

 

It's a 9.8cm dual-flapper. I am almost 100% sure. I have one sitting on the bench in the garage, but, I can't look at it until I get back home later to confirm it for you via the numeration.

But, it is a 9.8. I have been porting a 10.5 housing and comparing the differences back and forth, visually since I have them out side-by-side on the workbench. I just don't have the number at hand.

Maybe someone else will confrim the number, otherwise I'll post it up for you tomorrow. But, I do know for sure that it's not a 10.5. I can eliminate the 10.5 as a possibility by looking at your pics on the turbine inlet area. It is not a 10.5.

 

49378-13050 105 on my 10.5 hotside single flapper

 

pretty sure that is a 9.8.
And to the guy that said 10.5 is only dual is wrong. There are 10.5's that have dual flap and single.

 

I dont know, the Evo housing that I have and have seen are completely divorded units. This one is kind of not completely divorced between wastegate and turbine output. I have one out and it is like this one below. BTW this one is a 10.5.



Maybe yours is a 9.8.

 

My bad. I think is the gasket that make it look divorced.

 

I have a 2003 evo 8 turbo sitting here in my hands

Number on the casting is: 78-130100 115

 

Well, that settles it then, codean. That's the same number as if the OP's pics.
