Are you sure that you need to?

To what extent can I modify my vehicle?

Engine modification

1. Original engine modified

Modifications to the original engine are permitted provided the following conditions are met:

• normal engine reconditioning within manufacturer’s limits is permitted;

• modifications must not affect compliance with any emission or noise related ADRs;

• all emission control equipment must be retained and functional;

• If the modifications result in a substantial increase in power, then the adequacy of other components to

carry the increased power (brake performance, vehicle controllability, suspension systems, etc) as well as

the vehicle’s continued compliance with the applicable ADRs must be addressed.

the short answer is i don't know

the story is yesterday (sunday) my girlfriend got pulled up by the cops. they asked her if there is an engineering cert for the exhaust - she said she didn't know. they asked her to pop up the bonnet and check out my enginer. i got no mods there so ok.

then she got the bloke to call me and he told me i needed to go to get an engineering cert for the exhaust (turbo back).

do i need one - whats a good way to tell the police i don't need one (if indeed i don't?)

Theres a list of signatories here:

I would still question whether a signatory will really be that interested, and is really needed. I'd think that are only going to visually check whether you have a cat and then do a noise test. Seems like an expensive way to go about some simple tasks.

Unless the officer has given you a formal (ie written) instruction to do something, i'd be tempted not to bother doing anything. Maybe find somewhere that will do the noise test for free or a small charge just for peace of mind.

I'd be asking how some of the guys who get defected for noise get them cleared?? It might be cheaper to just take the defect then get it cleared.

An engineers cert will give you a bit more piece of mind for the future and should lessen your chances of being pinged again tho.

Talk to the Police Ethics unit and make a complaint. This crap will stop straight away. As long as you pass all emmissions then there should be no legality problems.

Contact the coppa and ask him to provide an order that requires the eng certificate so you can use it against him when you talk to the ethics unit, the state police ombudsman, your local member of parliament, the police minister etc.

Time to educate yourselves and take the fight to them.

    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
