i have all jdm itr vale-train its suppose to be better ??
its also ported with 5 angle valve job by excessive motorsports i think is the name ?? (blue springs colorado excellent work) but anyways i cant comment to much on it because the work was done the same time the valvetrain was installed.
there suppose to handle high rs ??? im probally going to be selling my valve train and going all ferrea. as ignorant as it sounds i didnt do my homework to much for this modification. faster revs likes to hold the rs better also very very loud (which isnt to my enjoyment !!!) ide go for it
