Do mean the small frame twin scroll is too long? (6258,6758,7163)
I fully understand the medium frames aren't going to fit. (7064,7670,etc.)
On the dimensional reference there is only 9.1mm difference between the 179388 and the 179374.
When will the twin scroll housing be available for the 58mm turbine be available? Part Number is :11581009007
Still comes up invalid on BW site.
Don't need or want a 52+lb./min. compressor, but twin scroll, yes.
