What parts............... It may help??

All good with the pressure now, but still not sure on what oil. The 90*c and 105*c is my water temp, i dont have a oil temp gauge, so i have no idea how hot the oil was.

I did read this, and other post's on this topic. This is my situation, i have a standerd rebuilt s1 rb25 (5000km old) Just did a track day. temp at track gets about 105 atm (will be sorting this out soon). sprited driving in the hills see about 90-95. In example 2 of the above quote, it talks about oil thinning at higher themps...... i dont quite understand what im needing to use at these temps. Also, what should a warm s1 rb25 oil pressure sit at when idleing? i have a apexi oil prerssure gauge, but am un sure of whats good and whats not EDIT: After further research, i have came accross some spec's on oil pressure that say the following RB25det KG/CM2 (bar?) Warm engine** Idle 1.1 kg/cm2 2000rpm 3.5 kg/cm2 6000rpm 5.6 kg/cm2
