Not to create discussion RC_Alan, but you are confusing the old Mugen MT12, which was a long conrod engine that had a thinner head button with the new Mugen X12 which has the same head button as all the new Nova based engines.
By the way all Nova based engines are long stroke engines 14.00 mm vs 13.80 mm bore , and the RRL3 are even longer 14.25mm stroke vs. 13.70 mm bore.
The difference with the old Mugen MT12 was conrod lenght but not actual stroke.
That is why you yourself suggest the RBV12 turbo button, which is the same as the Novarrosi NS3 or TOP TS3 or REX RERS3.
So my suggestion is still valid. Any new based Nova engine tiurbo button will fit, I've done it.
