Hello again,
All RB motors have a potentially dodgy oil pump, RB26 out of a 32 has a greater chance due to its age.
If you want to do track work safely ,get a larger sump and as Ash has stated, get some restrictors to stop the top from getting to much oil.
As you are getting a larger sump get the oil and water pumps. Jun oil pump with collar if you are really serious. Also get the Bearings ,Bolts and timing belt changed .
Then you might have a reliable car
There are too many things that can go wrong with the RB26 motor....if not looked after properly.
The supporting mods. are endless but the Mod itself must be maintained for it to work.
Anyway like you and Ash, I too am a modoholic (?) .
Thus, I am on SAU to navigate my next steps.
Cheers and good luck
