I am currently running a single cam turbo setup. Its been good to me. I am currently putting together a b20v setup using jdm b20 and b16 head. I plan on using a sandwich plate for the vtec conversion. My question is should I get oil for the turbo through the oil pressure switch or is it ok to get it from the other port on the sandwich plate? I was nervous thinking that it may take too much oil from one spot.

 

its better to use the port on the sandwich plate... the plate moves such a large volume of oil it wont hurt anything..
just be careful with the stock b20 sleeves... they've been known to crack like eggs because they are so thin
