mass production engine has huge tolerance on engine parts and its weight...
engine balancing is to make sure all pistons and conrods are the exact weight... crankshaft will be fully balanced so dat there is not even a tiniest vibration due to imbalanced counter weights...
after doing engine balancing, ur engine will rev up more smoothly and able to achieve higher revs limit....
if not mistaken auto gen got sell... it is used to stop ur brake pump from moving forward each time u press on the brakes... this improves the braking efficiency and more direct feel...
port polish intakes with 3 angle cut??...
high compression pistons??...
4g93 block??...
stiffer valve springs??... since ur highcams has higher lift...
port match intake manifold??...
larger throttle body??...
tuned length exhaust system??.... (i'm not jz touching about extractor, i mean the whole pipe to suit ur current setting)
multiple spark discharge??...
racing clutch??.. (if manual tranny)
u mivec-tised ur engine already right??...
they do engine balancing before putting everything back together....
lulz, thx for the info, someone gave me false info
