So I had my ecu retuned ( JWT ) this past spring and went to a bigger injector ( 72lbs ) I didn't buy MSD injectors but new Siemens MSD "style" injectors. The body was shorter and I had to double up on the injector bushing in between the injector and mani to make it fit. Well all summer long I had problems leaning out ( the plugs looked ok though and it felt fine) . It was creeping up into the 12's in the upper RPM's. I kept trying different things to correct it. Did the basics.. fuel filter, boost leak test ( to make sure it wasn't leaking form the injector bushing ) and tune up. I had installed a new Aeromotive FPR when I did the injectors. And a new Walbro 255. I couldn't figure out what was wrong and I ended up just cranking up the fuel pressure to compensate. I was at 3.5 bar instead of 3 bar. Then my wideband took a shit and I was thinking it was just my wideband the whole time. So I turned the fuel pressure back down to 3 bar cuz it was idling like crap at 3.5. So I went to an auto-x in august and after that I had a knock and blown up clutch. So I just got around to doing the bearings yesterday. #3 bearing was SMASHED! I mean SMASHED! 1,2 and 4 looked great. ( side note I had done new bearings about a year before ) So obviously # 3 injector or something is not working right. Should I just get real MSD's and throw them in? Just currious what you guys think. Any info is appreciated. On to the pics...
Good and bad bearings for comparison
