Sr20det: Cavitation or lifting head? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Im having an odd problem with my SR, and I was wondering if you guys could lead me in a direction to start figuring whats wrong with it. Its a black top s13 sr, with 550's and a 2860RS turbo. Its currently set to 17psi on stock internals and tuned for it. When ever though the car is over 6000rpm the temp gauge will jump up for a split second then settle right back down. It's like it jumps about half a temp mark then comes right back to where it was before, between the second and third temp. mark. Is this cavitation or is it lifting the head when its doing this?
