ok,i had my engine rebuilt a few months ago (8 to be exact) and everything was fine up until about a month ago. my car wouldnt rev past 6800rpm's like if hitting a rev limiter or something. its weird. anyone know what this might be? also, now as the rpm's go up my car seems to hesitate like it wants to go, but dont, then at about 4500 it hits hard. im thinking maybe my turbo's r messed up? i had them switched to non-sequential and my motor was mildy ported with 3mm apex seals. if anyone knows anything please let me know. thanks!

 

i have no idea but one night mine would not go past 7500k the next night i hit 9k rpm and the clutch popped itself out, so life it good now
