i dunno what else to do to my motor without tearing it apart. right now my motor has 115k miles on it. seems to have great oil pressure according to the guage( i know that the guages are off a bit). im wiring up my mass air this week when i get my 24# injectors. i got the delete kits on it with an explorer intake, headers, 3.73 gears and lower control arms. im wondering if there is something else to do with out seriously taking the motor apart. i plan to rebuild in 2 years. but my car is starting to feel slow and i need more power. any info would be nice
