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.

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,

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?

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
