Hey guys.. jus wonderin if ae86 need to have cats.. I know that pre 85 models dont need to run a cat- does this still apply to 86's if u have an engine conversion (4age, gze, etc) ????
i jus f*#ked mine and im wonderin if i can get away wif not having one at all
I have been using a metal cat, check out the link in my signiture for my worklog, it has extensive pics. The problem with putting a cat under a sprinter is that it is usualy the lowest point in a car and it is prone to scrape so there isnt a hell of alot of vertical room free. This is why I chose the metal cat, apart from the amazing flow its real short and is only 120mm high

oh and as for your question, your car isnt legal as it is and not having a cat may just make it more illegal, might depend on your state

in WA the loop hole is..is the car didnt come with one, it doesnt need one
yea iv herd people say that bout NSW but im not sure bout it???
In Qld it applies to the date of the engine not the chassis. So 4ac no cat needed, 4agze needs a cat

ae86s love since 2004
when i went to the exaust guy he said to yes i needed one because it was the engine not the car (4age 16v) but then when i got the system 2 months later he didnt put one on. so im happy
In NSW if you put an engine from a car newer than 1986 (ie smallport 4age, 20v, etc.) then you have to fit a cat converter. Your car won't pass engineering without it. If you get pulled without one and they send you to the EPA for a test, expect BIG fines. It's not worth the risk, put on one.
In Australia, whichever state you are in you definitely need a cat con on a 4AGE to be legal from an emissions point of view. The vehicle emission control information label , the green sticker on the bonnet for a corolla (with 4AGE engine) specifically states that the Exhaust Emission Control System consists of EFI + O2S + TWC. Obviously the EFI and O2S (oxy sensor) are obvious. I had always thought TWC stood for twin cam as they are supposedly emissions effective. However per the Repair Manual for Emission Control, TWC actually stands for Three Way Catalyst (TWC) system! So the answer definitely is yes. You could try and convince a copper otherwise but you wont stooge the EPA. I have heard that buying the emissions sticker (also a RWC requirement) from Toyota has become difficult. Though you could try and find one at pickapart.
my motor is a bigport 4age with gze externals bolted on? so technically the motor is pre 86 or wateva??
