Correctly manufactured headers that keep the turbo over oillevel. There is no other correct way to do it.

I think the cheapest and most proven relible one is the pump FBM (Dave) sells...

i presume nitro's is the same, but mine is driven by the socket cap bolt which holds the ignition rotor on.
just make a drive shaft with a hex on the end which fits into the bolt.

That's how we did mine - the emtes pumps have a hex drive that suits an M10 cap head so we cut one down to right length and turned the threaded section into an M8 hex key to fit the rotor bolt.......simples!

Correctly manufactured headers that keep the turbo over oillevel. There is no other correct way to do it. It's not always possible to get self-draining height, no matter what header-making skills you have. Clive, you need the oil pump gear set from a pit bike engine. They are (from memory) 8.7mm thick on the engines that have the primary-driven pump. The secondary-driven pumps have thicker gears which shift too much oil. Fit them into a housing with no more than 2 thou lobe clearance and you're good. Make a drive spindle with a 8mm hex on the end and drive it off the end of the crank, all you need to do is swap the crank bolt for a M10 fine thread socket cap.
