exhaust housing

[steveinaz]

I have a holset H1E turbo and housing. the exhaust has a part # of 3522723. My question is 'what size housing is this ?' It has a 26 and a 129 cast into it below the part# casting.

Also will a HX40 16cm housing work on the H1E turbo?

look inside the housing where the housihg meets the exhaust manifold and inside one of the ports will be a number, thats what size it is,
