Hi all, New here, and new owner of an R32 GTR. I have recently bought a digital multi gauge to monitor my boost, oil pressure, oil temp and water temp. An added bonus of this digital gauge is it allows for the input of minimum values before it's safe to start driving and maximum (or minimum) values which, once reached would set off an alarm so you can act accordingly. Despite my best efforts (including searching via the forum and google) I can't seem to find a solid answer for the minimum and maximum ideal values for oil pressure, oil temp and water temp (not boost as obviously that is dependant on the vehicle). I know this may change with engine builds, oil types etc BUT, I am thinking there must be a best guess value for these assuming a stock rb26dett? If I have missed a thread where this is covered I apologise but am happy to be corrected!! Any help is appreciated,

Hi guys I have an R34 GTT and am concerned with the boost levels it's running. It has some basic bolt-ons including a front mount intercooler, full 3inch de-cat turboback exhaust, apexi pod filter and custom cold air intake. The stock 2-stage boost controller has also been grounded out. However I've been having issues with how much boost it's running. It's occasionally hitting the 1bar mark on the factory boost gauge, and it does not have a boost tap. I believe that was causing issues as the car had severe flat spots through the rpm range and was missfiring and spluttering occasionally on boost. I read up and unplugged the factory 2-stage controller and it now sits on 7psi constantly, which i'm much happier with. My 2 questions were, why/how is it boosting this much without a tap or controller, and could the missfire/break up I was getting on boost be because of the boost levels it was running? Feels fantastic on 7, and pulls properly the whole way to redline. Have checked and gapped my spark plugs to .85 too. Was planning on getting it tuned on a link ecu but just wanted to check for ideas here first about those two things. Thanks guys
