Bushpig Posted April 15, 2014 Report Posted April 15, 2014 (edited) 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 Edited April 15, 2014 by Bushpig Quote
It's_AUDM_Yo Posted April 15, 2014 Report Posted April 15, 2014 Well sort of irrelevant but maybe similar in QLD, You just need a modplate for change of induction and get it emission tested. I would believe the CAI or pod filter thing is rubbish because neither of them really do anything at all Quote

But yeah Queensland seems a bit more laid back in terms of car modification compared to vic. Quote
It's_AUDM_Yo Posted April 15, 2014 Report Posted April 15, 2014 Yeah just the easy one, Could be different there though. Nah not really we can get our car impounded for 90 days if its "illegally modified" Quote

philbey Posted April 25, 2014 Report Posted April 25, 2014 Bushpig have you actually spoken to an engineer. It's likely that your car only needs to comply to the ADR's current for the year of manufacture. Pre 87 ADR's are typically much less of an issue. Trumpets inside a plenum shouldn't be an issue. Trumpets with socks also shouldn't be an issue with EFI for a car of that age. The problem will be that your intake noise is too loud for required noise limits 1 Quote

I was under the impression that it was to the adr of the engine? Quote
ke70dave Posted April 26, 2014 Report Posted April 26, 2014 The reality Is the only person who's opinion counts is the engineer who is going to approve it. 1 Quote
