It's been literally years since I built mine, but I think I went with a rubber ABS hump hose coupler (flexible coupler for ABS piping).

I then cut the coupler at its largest part for larger-inlet turbos. I use the smaller side of the coupler for the CT26.

I want to say I went with a 2.5" coupler since the OD of most higher-performing turbo inlets are closer to 3".
