Hello together, I brought my 740 with B230ft bj. 1990 (approx. 175 000 km) a few weeks ago the engine completely disassembled connecting rod new piston new crankshaft to grind (with the pistons I have chosen a lower thickening because I might want to increase the power even a little bit) Turbocharger also got a new fuselage group running smoothly. Now to my problem It starts with a fairly low speed (approx.500 u/min) goes off and off Also when I give gas it turns very sluggishly high to a maximum of 1000-1500 u/min After about 1 min at 1500 u/min the curved and the turbo starts to glow. My first approach was that it runs too lean and therefore burns too hot but the Blinkbox also doesn’t spit a fault from Lamda indicator lights up but also does not apply to fuel at the injection nozzles also with good pressure. If someone still has one on what it might be or what I could still check ? Thanks in advance
