Rb25 Failed Nsw Emissions Test

[r31rb25help]

im currently trying to get my R31/RB25 turbo registered in NSW. took it for an emissions test today and completely failed

using all stock parts for the emissions test bar a 3" exhaust, turbo is at 7 psi.

high flow CAT(i think this may be causing alot of the problem it may be screwed)

any advice on wtf went wrong would be great

here are the test results.

First things first high flow cat is not gonna be emissions standard you need a stock cat I used a xr6turbo cat for mine but any factory ceramic cat should do the trick

Yep.

And why do u need an emmisions test with a standard ecu? Have the rules changed? Try another engineer

apparently i need the test because the engine im using is imported.

im thinking i should just replace the entire exhaust system on it for something with passing this damn test in mind

and i dont know what to to about it dumping about 2x the fuel its allowed to into the exhaust at the moment,

Ring a different engineer. Just did a 26 in a vl. Engineered no probs without emmissions test. All stock

dug up my old stock exhaust and put 2 3way CATs on it after some advice from a mechanic, looks like horrid and runs horrid but it will apparently pass.

he also recommended i dont run my intercooler at all just a "straight" pipe.

He's trolling for sure. Ask him if he will pay for the new engine after yours goes bang from detonation?

why is it dumping 2x fuel it should be into the exhaust? if it is overfueling heaps then theres no way it will pass have you got bigger injectors in it or something?

pretty sure the rules are:

fit ALL stock emissions gear -> no emissions test

leave stuff out or change the setup -> emissions test
