I'm coming up empty on finding a whole lot of info about using the WRX scavenge pump on the BRZ. I'm creating a custom turbo kit based off the PTuning kit and using a MGT2259 from a '17 WRX down low, so I'll need a scavenge pump. I couldn't find anyone selling the adapter plate by itself, and after getting a prototype designed and printed I'm realizing the pump needs modified since the 1/4" plate will bump it out enough that it doesn't engage with the cam. Does anyone have experience with this? I'm between two options: weld an extension on the cup that engages with the cam and risk an imbalance, or press out that cup from the pump guts and risk hurting that $200 pump.
Printed prototype that will be cut out of steel:
Can I press the center part out a bit (darker metal on right-side piece)?
Thanks in advance!
And for any of those interested, here's an album of the progress so far:
