I just bought a 1986 5000cs turbo with a 3sp auto. It has 104,000 miles on it. What is the maximum turbo boost pressure under full acceleration? From standstill, I could, at best achieve 1.3 bar under 4000rpm. Also, I know that there is a spearate oil filter for the turbocharger. Could someone tell me where it is located because I have been unable to find it. Thanks for any help.
