After some opinions on the best oil pump gear for a turbo set up. Toda or Prodrive seem to be the two choices, however have read a fair few failure stories on this site about Prodrive and lack of customer support.

My OEM GSR oil pump. Ran a lightweight alloy crank pulley with no harmonic damper, bad idea.


Rebuilding the motor now starting fresh with a new block, Darton MIDs, ATI harmonic damper and lots of other goodies, fully balancing the rotating assembly again.

Aiming for 400-450whp with a GT3076r. Street driven all rounder (Street, Strip, Circuit). I don't want to experience my oil pump shattering while doing 250kmph down the back straight a second time

Edit: Won't be revving anything over 8600rpm either.

 

Just use a new OEM pump. You'll be fine...

 

I've had the TODA Racing 80mm pump for about 6 years. They have not failed at all yet due to the better construction of material over the OEM. For the circuit, they are fantastic to use. I'm not familiar with the prodrive as much, but seem to be ok.

 

exact same thing happened to me last year while tuning on the dyno!! i was using a professional products damper. also costed me a rebuild. and i didn't rev passed 8200rpm. i'm currently just waiting on my toda oil pump gears to arrive this week and i have returned to the oem harmonic damper.
