I understand that the new systems come with two oil scavenge pumps now. When I got my system they use a single pump, which seems to work fine.
I assume the system is used then? Hopefully the turbos are OK. I recently had mine rebuilt as the impeller shafts had play in them. Plus I needed to go to larger housings with the new engine.
You'll enjoy the hell out of it when you get that installed in your car...
Turbos give a real interesting surge of power when they spool up under load.
