More progress...
I got the rest of my intake parts for fitting the compressor in the BRZ. It's a close fit, but a good solid clean fit. I'm pretty happy with it.
Next step will be bench testing the compressor. I think I'll have the rest of the parts for that tomorrow.
Edit: I'm going to have to hack up my Grimmspeed pully cover if I want to keep using it. I'm a little disappointed by that but oh well.
