Making changes to Turbo

PM me your name and I'll look up your invoice. Based on backpressure tests of the #8 vs the #10 - nothing else changed, the #10 was a clear winner on reducing backpressure without any loss in spool performance.
The issue here is availability. Turbonetics will no longer make a #10 KKK replica unless you're willing to commit to a batch order of 50 units. Clearly there is a perception that a #10 is too big for a 2.5L engine, but the reality is that if you put a standard Garrett .63 housing - which is bigger than any KKK housing that will fit this 50 trim, it would perform even better.
Using a Stg 3 turbine wheel, a #10 turbine housing works very well with a 50, 60 trim etc.

As I mentioned to Vic in my PM that I don't think Rob got it from him. I recall him telling me (or reading one of his posts) that he had swapped out the hotside himself to a #8 from a #6.

My impression of things I have read on RL is that the #8 can end up causing high back pressure that was my think on changing out the housing.
Does Tial make a housing that would fit this turbo? So far we have Vic's suggetion
Thanks
