Got this from the Z1 blurb on NA>>TT conversions: Oil pumps are different. They mount the same and are the same internally (on earlier models) except for the spring for the pressure valve in the TT one is tighter so it produces more needed pressure to circulate oil to the turbos and cooler. You can actually just change the spring to the tighter one. The 94+ NA oil pumps and the replacement NA oil pumps from Nissan are different internally to the older ones and the TTs. They have internal gears with larger rounded teeth.
