Hi im in the the process of enlarging my 1jzgte plenum and ading a extra throtle body to it as im interested to see wat the affects will be ive read somewhere that aiming for atleast twice the engine capacity as the volume of the plenum is ideal. im intending to basically double the volume of the factory plenum and adding a aditional 1j throtle body with aditional feed from intercooler ive seen a few 2jz with big manifolds and 100mm throtle bodys and subzero in australia seems to do this sort of thing to many of there carsd oes any one have any sugestions or technical info about these mods im intrested to know the physics behind it all and wat is the best way to go about it. input and discution appreciated
