I have just rebuilt a 1989 BJ 74 13BT engine. It appears to have less power than my BJ70 3B non turbo had? The engine rebuilder has a great reputation and did an excellent job on my 2H engine a few years back, so I doubt that a mistake was done there. Here are some stats that may assist, Turbo spools up very fast and peaks at 9-10PSI, EGT's come up very fast as well Engine sounds normal, no vibrations, nice stable idle, no smoke . However at 95 to 100Kmh, EGT are close to 1200 and will climb to 1400 if pushed past this speed. While the rebuilder marked the injection pump houseing mounting to engine, could improper timeing cause high EGT, high Boost and low power? Any assitance would be greatley appreciated and perhaps guide me as to where I should be looking.
