So, ive had a catch can installed on my car for a few months, and it feels like my oil pressure is too high. I did a oil flush when i installed the can as well, 5w40 (maybe thats the cause?). If it isnt the oil thats causing high oil pressure, im thinking maybe the can setup?. Its non atmospheric, 1 way valve still connected to plenum, and plumbed from exhaust side to can, can baffled with loose steel wool, and plumbed back into intake before turbo. before putting on the can and oil change, at idle it would sit at between 1-2 (on the stock oil pres gauge), but now it sits at 4, and at pre 4500 rpm boost, its at like 5-7 on stock gauge. it seems way too high than before.
And for the second issue, the 2 stage boost is still active, its a jdm rb25 swap with what appears to be using the rb20 harness. According to the R33's, the ground for the boost solenoid needs to be grounded to the body, but since i don't have the rb25 harness looms im guessing the ecu is acting like its still an rb20. the wastegate is directly connected to the i/c pipe but it still stays at 3-5 psi until 4500 rpm then it gets to 7 psi. How can i disable the rb20's 2 stage boost? or is it not possible with rb25 turbo?
