Just wondering if some one could fill me in on any physical differences between the NA oil and the tii oil pump, I'm about to finish building my 6 port turbo how ever I read a while back that the tii oil pump does indeed flow more. I have several oil pumps, just can't tell which is NA and which is turbo. Any input is appreciated

The turbo oil pump has wider gears and is a much higher volume pump

...Which makes the N/A pump better, since that means it cavitates less, which means it flows MORE oil when it counts.

I get 90psi oil pressure by 4000rpm and it does not fall off all the way up to and past 10k.

Oh, wait, I'm not using a FC N/A oil pump, I'm using a 12A oil pump... even smaller!

Funny how the pumps kept getting bigger but the oil inlet didn't change.

Alright peejay, you got me all confused now, I figured the oil pump that flows the most would be best suited for a turbo application , can a seasoned veteran please shed some light on this?

Use the turbo pump it is much better

Do you happen to know a way I can distinguish an NA from a turbo oil pump? Any markings or dead give aways?

flip the oil pump rotor/stator out into your hand.. the bit that falls out with the dot marking

it is physically wider ( taller ) than the NA pump
