just a few questions and need help regarding tips for passing NSW emission testing??
i am just about completed my turbo setup on my au falcon ,and was wondering if i removed the wastegate spring and do the test will it pass ?

chuck about 300mls of acetone in the fuel tank. This apparently helps. There are a few sites about a little acetone in the tank improving fuel consumption and a few people in the states have also stated how it also made their emissions improve. Remember Californian cars get checked every year or two after a certain age.

If you remove the spring then it would make zero boost right? If it does that then you would most probably pass emissions provided that your mixtures and timing are spot on. And I do mean spot on. But on the downside you would most probably fail a noise test because all of that air is bypassing the turbo and going straight into your exhaust without being muffled slightly by the exhaust wheel of the turbo. This is prominent when running straight through unbaffled mufflers and is even more noticeable when running screamer pipes as its like you have your exhaust disconnected at the headers.

thanks for the feedback guys,
well the car has got a dev3hl cam, and 2.5" exhaust and unichip tune, so my question is will this pass with a turbo attached and wastegate spring removed ?????
please surely someone in here can help with emission testing????

its the dark side of the moon.... very few have attempted it

Well thanks ebs!
looks like i will cancel my turbo install, and maybe buy a xr6t some time next year

Just put your spring back in and try and give it a half decent tune. Emissions tests in NSW are free and they don't give a s**t if you fail. Just keep taking it back till you pass.
