Hey guys, Just wanting to get some advice regarding using velocity stacks on a 4age, whether or not this is legal/engineerable? (just running the stacks, not inside plenum)
on an 4age 20v blacktop going in a ke55. (located vic)
Just trying to do all my research before buying parts and before talking to an engineer.
i know you have to keep all emissions gear with the engine conversion and i know i read somewhere you can have pod filter or cai but not both. Just trying to figure out what area velocity stacks fall into?
Cheers
