I bought a Boundary Engineering Stage 2 oil pump a couple of years ago to install on my 1999 NB engine. To cut a long story short; life got in the way and 2 years passed by. I finally got around to installing the pump, but this time on a VVT engine.

I've read that not all Boundary engineering pumps are compatible with VVT engines. How do I know if the pump I have is suitable for VVT engines or if I need to sell this and get another?? Pics below:
