these are the helms specs for the b20z2. seems like this might help future members in their search. i couldnt find it during my search so i downloaded helms and found it.

intake 0.08 - 0.12mm
exhaust 0.16 - 0.20mm

my question is are these specs good for performence? reason i ask is that it seems that the b20z seems to be the most under rated b series motor out the factory. from the goofy looking header to the girrafe style intake manifold to the small tb, it is obvious that they didnt have performence in mind. for the most part my motor is pretty stock. here is the setup

stock b20z longblock
oem hg with middle layer removed
blox intake mani
stock ls header


should i go with these specs or should i go with something smaller closer? if you have a suggestion please leave an explanation. thanks

also is there an thread for just non vtec b20 dynos.
