HRC O2 Housing

I have an 89 colt/mirage hatchback, and im going to swap out the stock 1.5 with a GST motor. My boss had currently run the setup (TD05) and the turbo flared to 20psi before back down to 15....so im going to get HRCs 02 housing...does anyone have it? i wanna get some reviews on it before i go out and buy anything....
