I'm not sure abt the water cooled FMIC....but they will not give permit for them..even tho if you passed the pit....

I think custom boot isntalled sound system are illegal as well...beacuse you need to remove the spare tires to have them installed..

Harleys are the only production bikes without muffler...I think I read sumwhere...but not a lot of ppl own harleys I guess...

that's their trademark..no mufller...

Its not hard to get the correct info yourself rather than take your choice of alot of the "my mate was told" or "the guy at the pits I went to said" conjecture that is in here. Go to the pits and ask for copies of half this stuff - I did. Or some of the straight forward stuff is on the dpi website. But yeah - every inspector will have different "let you off" levels - but if you want the technically correct info then get the written guidelines on them all.

Like for wheel/tyre aspect ratios and width info: http://www.dpi.wa.gov.au/licensing/1884.asp

(eg rims no wider than 7" unless it was a factory option; rim OR tyres not to extend factory maximum track width by 25mm total (12.5mm each side); can go up two inches in RIM diametre but cant increase overall tyre diametre and still cant go wider than 7")

For exhaust systems: http://www.dpi.wa.gov.au/licensing/1885.asp

(eg - theres no set dB limit - it is quoted as "The noise level of the modified system must not exceed the noise level of the manufacturer’s original system by a noticeable amount")

Alternative steering wheels: http://www.dpi.wa.gov.au/licensing/1886.asp

(eg cant be smaller than 13")

Suspension: http://www.dpi.wa.gov.au/licensing/1889.asp

(eg cant lower actual suspension more than 1/3 original bump-stop etc... but interestingly we dont have 10cm rule for accessories or spoiler lips etc which can go lower down to tyre profile width... "No part of a vehicle or accessories (except flexible mud flaps) shall project below the lower edge of a wheel rim")

Bonnet scoops: http://www.dpi.wa.gov.au/licensing/1913.asp

(ie NO rearward openings allowed for vents - not even MESH like someone suggested) Again you can ask for the full spec sheets - which i did for bonnet vents and scanned showing measurements etc:

ScoopOpeningSize.jpg

Thats just the few on their website - they have loads of the more detailed info sheets you can request - I just walked into the pits and got copies.

The only bit of "i heard from a pit guy" info I will add to the other conjecture in here is that when I got all the sheets about wheels/tyres, the guy a spoke to said while it was still strictly the 7" wide rule... this was one set of guidelines they were reviewing as there is recognition that expecting people to go from 17" to 19" (as allowed under the + 2 rule) but stay at 7" wide was ridiculous ... ever tried to find a 19x7 rim??!! But he didnt think it'd change soon even though it is being reviewed coz it just takes ages in govt depts to change anything.

So the no rearward facing vents, is that because of a fire safety thing? What if you blocked off the vents from underneath the bonnet so nothing could get through with like a detatcheable plate or something?

"But my mom says I'm cool."

Its not hard to get the correct info yourself rather than take your choice of alot of the "my mate was told" or "the guy at the pits I went to said" conjecture that is in here.  Go to the pits and ask for copies of half this stuff - I did.  Or some of the straight forward stuff is on the dpi website. 

or, you can just quote a heap of stuff off the dpi website which is out of date, and unfortuneately doesnt take into account little things like ADRs. (state things like Max DB level of a vehicle exhaust - try reading them) and local road laws, which state that cars must comply with ADRs applicable for their year of manufacture.

You cannot just use one source if you want the whole picture - there are many complementary publications out there, which all need to be read together - or, you can just speak to the head inspector (reno?) at welshpool, as he is the one the other inspectors go to when there is doubt. If you dont like his interpretation, you can take your car to an engineer.

If you want a rough guideline on what will and wont pass, try listening to people who have ACTUALLY HAD THEIR VEHICLE PASSED - the DPI site, its pretty out of date, and can be somewhat misleading if you use tunnel vision.

For those worried about rearward facing vents, dont be, if its the style used in CF bonnets, they are fine as long as the car predates the applicable ADR for compulsory front end collision testing, FACT (go ask reno if you dont beleive me)

Sorry to open ancient topic (been searching for this answer for wa and cant find it), but i would like to know if externally gated turbo system is ok? As i would like to go down that avenue soon

I know some of these posts say its cool if its not to loud but there must be an update as that is old

Sorry to open ancient topic (been searching for this answer for wa and cant find it), but i would like to know if externally gated turbo system is ok? As i would like to go down that avenue soon

I got a yellow on my 33 last year & after they drove it they said I had to get a permit for the turbo & everything else because of the power it was making. Even though it was plumbed back & everything, once I applied & sent in the form they then asked for an emissions test for it. That's where it could be a bit tricky, as I had to go down this avenue, sky34 the same & so did another member that we helped each other out as it was around the same time.

r32 driver did you have a yellow but get through alright? At around the time we all got our yellows off & permits they were changing the emissions testing. We all got an emissions test done for compliance as well that was ok (although I had to fight for mine, over xmas & new years too! A big reason it took so long for me), but they were changing it to something called the IM240 test. No-one in Perth did it at the time so that's why we were ok but because WA adopted the national code of practice, there is one company that brought it in. Apparently the cost for that was going to be around $800, not bad for a 4 minute test hey...

Before you do anything I'd say make some phone calls & get all the info that you can first hand :P

i think i passed a couple months ago now

i had an engineering certificate, all they checked was the certificate number to the mod plate on the car ($500-800)

all my stuff was plumbed back bov, wastegate, catch can etc

no emmisions was tested or power etc

so does that mean my hks ssq series 1 is ok to pass pits?? what about the hose i have blocked off?, or should i just put the stock one back on?

you cannot have any type of atmo venting BOV on your car ...

if you currently have one welded to a pipe or something and you need to goto pits, disconnect the vaccume pipe that goes from the BOV to the plenum so it does not sound when shifting etc...

or even better, remove that section of pipe and replace with standard metal pipe until you pass pits, if possible..

Tyres on a 9" rim can be no lower than 235

and more on what mitchy said earlier..

if your car came with 16" wheels you can go up 2"

so stocker R32 for example , with 16x6.5 you would be able to put any wheel on between 16" and 18"

width: you cannot have them larger than what your tyre placard states . ie. 16x6.5 17x6.5 18x6.5 ..... according to DPI

ALTHOUGH , many pits in WA have no real way of checking width , unless its blatently obvious and stamped on the wheels for them to see, so really if your plac on the door says 16x6.5 and you had 17x8s' on there u wouldnt get reemed ...

If your tyres TREAD sits outside the guards it is illegal. tyre wall is fine (in case of larger rims)

spacers are illegal

ride height should be NO lower than 10cm at the LOWEST point of your car

eg. look under your car, find what the lowest point is (excluding wheels obviously) and see if you can put a COKE CAN under there fine... if not , you need to raise your car

you should not need an exhaust emissions test when going to pits for a yellow, just make sure it is under 92db (get it tested at a muffler place for $15 before you go to pits)

Tint on rear window and rear 1/4 or rear passenger (in case of a 4door) can be less than 35%

passenger and drivers side front windows cannot be less than 35%

and unless your car came from factory with tint in front windscreen , it should be completely tintless.

Ext. wastegates should be plumbed back into exhaust system before cat.

seatbelts must lock when pulled forward (towards front windscreen) and also lock when pulled towards the floor of the car, they must also retract quickly

Rollcage info on the last page is correct

holes in the interior are illegal , Eg. no cd/deck/tapeplayer.. just a hole, is illegal

no speakers in rear shelf, and bare metal showing , is illegal

no carpet on interior is fine, no carpet + stripped sound deadening is also fine, as long as the driver has carpet or something other than metal , where the heel touches the floor (under pedals) in case of water + slipping

Gear shifter info on last page = correct

any more questions feel free to PM me or ask here.

Edited by coFF33

Hrmm.. Emissions things that need to be vented to the exhaust before the cat.. What if your car is pre-86 and didn't come with a cat? Then can I have an atmo catch can? Or do I still need to vent it to the exhaust? Haha.

Would also be interested if anyone knows about chassis strengthening legalities?

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
