Haha yeah i have that exact link and printed out earlier today.. im using an N1 pump will be mostly street and odd track day so i thought blanking rear and 1.5mm in front would be ideal as stated. Will have extended baffled sump also and already have mines baffled rocker covers with custom baffled catch can (currently on my 26) aswell as getting the rear drain/vent on the rear of the head.. just wanted to see who would second my thought. Seeing that 26 factory is blocked rear and 2mm in the front
