well im looking at buying a silvia, most of the nice ones are running external gates.

is there any point hiding them? abviously the coppa will know you got 1 just from the sound but if he cant see it and its hidden by bolted down panels and stuff can he still get you for it?

how bad are the fines? i heard its classified as having no cat, so it can be a fine of like 10grand. and if you got 1, wat can u do to pass it over the pits, change the whole exhaust manifold and turbo? then u wud need a new tune and end up costing an arm and a leg.

and if u get caught with 1, do u get the fine on the spot or do they give u a few weeks to get rid of it and take it over the pits?

so wat i dont get it why so many street cars are running external gates risking like a 10grand fine... i must be missing something here

I dont live in WA so I dont know the exact laws but if the External Gate is engineered, plumbed back into the exhaust BEFORE the cat then I think it would be legal. If it is plumbed into exhaust after the cat or it just vents to the atmosphere (Screamer pipe) then it is illegal.

Who ever told you that is talking shit. External wastegates are the same as internal wastegates, only not part of the turbo. As long as it is plumbed back into the exhaust before the cat the exhaust gasses still pass through, therefore no extra emmisions are released.

A screamer pipe (vent to atmosphere) is illegal for 2 reasons. 1: Extra emmisions. 2: Noise. Sounds great though :D

They can yellow you for it, but I doubt they're fine you for it. I know plenty of people who have been stickered for having no cats, decat pipes, some have even gone over the pits like that. They fail, but it just means they dont get rid of the sitcker.

open gates are definitely illegal but those that are plumbed back before the cat are legal. cops will still sticker you for weird reasons but if you bring it to the pits they will pass. is there something about noise levels as well? some say that it cant be too loud.

There is a law saying it cant be too loud, however SN1P3R's car passed the pits 3 times with her exhaust before she got stickered for it being too loud. My exhaust has no turbo, cat, or any real muffler, and the resonator and cannon do sweet f**k all to muffle the sound. Therefore, you can hear it 3 streets away at high RPM. I am yet to be stickered for my OBVIOUSLY illegal exhaust.

dunno if its a good idea advertising how illegal your car is :spank:

as far as i know, they are not illegal as long as they are plumbed back.

Don't worry, I knew the risk I was taking when I wrote that. Simple cat swap and silencer and it's legal again.

ossie 21 has an engineered external gate

so they are legal if they dont vent to atmosphere

afaik they only do emissions testing over east, thats why people often pass the pits with gutted cats etc

:cheers:

They do emissions testing over here now, I had to get that done for my car. Apparently I got in just in time because they were looking at making people do something called the IM240 test (i think thats what its called), which only 1 place in Perth can do, and the cost was in the region of a grand :) BUT...since then I haven't heard much about that happening to people so I'm not sure if that's what people are having to do or just if the DPI were looking into it, I just did the test that is done for compliance to the australian design rule (39 I think it refers to) :)

external gates are legal if plumbed back before cat

however if its not and you have a after market comp you can set your comp to rev limit at 4k and loosen off a cooler pipe clamp so u got boost leak and say to the pits inspector its on run in tune due to being a fresh engine. The wastegate wouldnt open due to not reaching the boost limit hence you would be able to take the gate off and block the gate flange so they dont know you have one which would be legal..... or

just plumb it back, but that costs u money rather than 10mins of buggering around to trick them hahahaaa

By telling them you have an aftermarket comp you are screwing yourself over with them :) That won't work, you just have to have it plumbed back.

don tell em bout the aftermarket comp just a limiter on the coil leads or summin hahaaa they don no much theyre all generally old and carby experts hahaa

but yeah i agree just plumb it back if u get stickered but till then it sounds good loud :(

When my S13 was stickered I was caught going over the pits in the middle of their pay dispute. As a silent protest to DPI pit inspectors were sending all modified cars out with "Seek technical section approval" noted on all work orders.

I had to fill out a comprehensive application to the DPI Tech Section at Welshpool requesting approval for my high mount, gate, bigger brakes, exhaust etc etc. It was time consuming and agonising but at the end of the day I got approval for everything and not only did I get permits but I also had a full history outlining that my car was 100% legal.

If your going for a car that has an external gate why not look into requesting approval from DPI before waiting for a yellow sticker. At least if your pulled over in the mean time you can show the jellyback that your making an effort.

I'm planning to do that with my R34 now it's externally gated.

    • I'm seeing torque specs all over the place for the OUTER tie rod, but none for the INNER tie rod, where it connects to the steering rack. Even in videos, people are just tightening em up as much as they can with a wrench and that's it. Anything tightened down without torque makes me nervous. Anyone know what the spec is for it?
    • Hope you had a great time here in our tiny country.   The JDM scene we have here is quite small, it's mostly BMW, Volkswagen with burble tunes haha. But the few JDM cars we do have in the scene are pretty nice. Some of my friends drive cool s14's too. Both built engines, red one makes abt 500, blue one abt 400 i think?
    • Ye good idea , would have never thought of something like that. Might aswell do it to every pulley and the balancer while I’m there 
    • Use an LS1 or similar, via kit like Frenchy's. But.... It's probably not the alternator. It sounds like belt squeal, which would be because the pulleys are glazed. Rub every groove on the pulleys with 120 grit paper. Report back. Oh, and new belts afterwards too. The old new ones will be shitted up already.
    • Hello all I have 2 r34 sedans , one turbo one na, only recently aquired the na 34.  Man what is with these things.... My turbo 34 started sounding like a super charger, it was screaming at anything above 4000rpm , I took the alternator apart and replaced the front bearing which is the only one I think you can access and it did not fix the issue so presumably the bearing in the rear of the alternator is gone. ( diagnosed it was the alternator by taking off the aux belts one by one to figure out which pulley or bearing it was )  My friend gave me one he had lying around, Installed it , it did not squeal for maybe 500kms and now its started to squeal again briefly on startup  Recently got an na r34 and I replaced the timing belt, water pump + all the auxillirary belts. Runs amazing but it suddenly developed the same squeaking problem but significantly worse, Ive had my neighbour come down screaming at me because it was waking her up everytime I moved the car. It takes a good 2 minutes before it quietens down.  Im yet to diagnose where its coming from but im fairly sure its coming from the alternator aswell. My question isnt about how to fix it but rather where can you get a new alternator for an rb25 neo??? Ive searched everywhere but I havent been able to find a direct fit oem type replacement thats not genuine. All the automotive stores sell an oex one - BXA035 - which I picked up for cheap through a friend with staff discount , got it home only to find the connector is completelty different.... As far as im aware bxa035 is for rb20/30's and after a bit of figuring out the bxa035 has an ev14 type connector, which is tiny compared to the rb25 connector. I actually had an ev14 connector lying around which I was considering just replacing the bigger plug with to get the alternator working but the bxa035 is rated for 70amp vs the rb25 alternators are 90amp ( or so ive been told ? ) That paired along with the fact im about to install an amp + sub in the back and I have the stock sized small battery Im not sure itll do the job unless anyone has another opinion?  I know and have seen all the websites selling the ls1 alternator conversion kit but I am not going down that route, nor do I have the money to. Hopefully I can figure out how to get 2 brand new alternators for both cars. I would buy second hand which there seems to be many of but considering how common this seems to be im sure If I installed a second hand one it would start squealing in no time  Or even better if anyone knows how to fix the issue directly with the alternator itself... Any input appreciated Thank you     Link for bxa035 connector picture
