One genuine late model oil pump with seals! gaskets!
One of the weird things I’ve found: There are two different oil pumps.
Early models have 78mm diameter pump gear with a crescent shaped piece in the middle. Later models are using 74mm pump gears. Obiviously, AW11 has the early model, which is not compatible with the stronger Toda gearset.
I’m definetly going to run this new engine to the max, all the way to 12000 rpm so mod is much needed. 😀
Here is the original pump, with the crescent shaped piece between gears:
