The STi impeller may be designed to operate better at high rpms. It seems like ours will just not work at these higher rpms.
I've considered using the STi pump in the SVX, but until now could not see a reason why.

The sti impeller is the same. The WRX has the stamped steel impeller. I put pictures in post #1106
The WRX/Sti pump casting is ~8-10mm short and won't work on the Eg33 as It will not line up properly with the EG timing components.
