what standar fuel pressure?
 

Hi i have a 94 sti and wanted to know what the standard fuel pressure is? oh an also the oil pressure if someone knows?

3bar fuel pressure with no vacuum on the regualtor..

oil pressure on hot idle 2~3bar.. hot cruise about 5~6.. that is a reasonable healthy phase 1 engine..

Thanks for that i'll have to see what im running at as i've just finishing off a rebuild and have changed loads.

My MY95 was running 2.8 BAR with no vac (as manual states), fuel pressure will then rise and fall 1:1 with manifold pressure/vac.
