Hi all,

Recently I was given a nice little yellow sticker by our friendly law enforcement officials, and was told upon going over the pits that I must obtain permits for all the performance based mods on my car (intake plenum, injectors, afpr, high mount kkr480 etc. There is a five week backlog to even obtain permission to get an engineer to sign off on it all, so I have decided its not worth the heartache and I will be returning it to (nearly) stock.

I have just ordered a HKS GT-RS kit(going to be painted black and invisible), and I'll be putting the standard intake/exhaust manifolds, fuel rail etc etc back on

A couple of questions though:

1. Will the standard exhaust bolt up to the HKS dump? (My 3" is ever so slightly too low, by about 2mm at the cat so I will swap it over again after)

2. Boost contollers- I am guessing that these are illegal as well?

3. Intercooler - It is a genuine greddy so no issues with cut bumpers etc but are these legal?

4. Oil catch can - Does this interfere with the emissions side of things or will it pass?

5. BOV - Is the standard one likely to handle 18psi? Or am I better off getting a GT-R one fitted?

Thanks for your help :P

No.

high mount dump pipe won't mount up to a low mount turbo + manifold.

2

Yes, ability to modify a vehicles performance on the move is very frowned upon.

Same as coilovers, since you can leave the pits and wind the boost back up, you MIGHT pass with a manual boost controller, but be prepared to have to take it off.

3

Yes legal, provided you havent hacked up your reo bar.

4

Paint it matt black, use black hoses, etc and you shouldnt have any drama's. No bling.

5

Since you'll need to remove the boost controller, just use a stock BoV over the pits, the revert back to whatever you want.

Get a GTR one fitted later on if need be, say away from massive shinny aftermarket ones, they look and sound like shit.

:P

^^ mis read his question.

1: what he said. Downpipe will bolt up to the bottom of the dump pipe no drama's.

2: Depending on who you get they might still see it has a boost controller from looking at the wastegate actuator line. depends how much attention theyre paying. If its all painted black and nothing is standing out, you can probably pull it off, aaand like I said, alot easier with a manual boost controller, no line running back through the firewall.

Do aftermarket dump pipes look much different to standard? It just worries me that when the get under the car they might spot it..

Stock dump pipes have the same texture as your exhaust / turbo housing. Most aftermarket pipes are polished, just go get a can of VHT high temp for headers (about 1000 deg C), about $13 or so, easy fix.

New exhausts are favored at the pits, and aftermarket dump pipes arent illegal (unless they're screamer pipes obviously), so as long as it looks newer than factory and doesnt look like cheap bling shit they'll see it as a good thing.

Heard about you doing this Shae :( They even had a 3/4 week backlog back when I get my first yellow sticker on my old 33 a couple of years ago...way to keep on top of it lol. Danny recommended to a mate to avoid something like this happening (due to the way it is these days with police & any modified import), the best way to go would be a GTR with aftermarket low-mounts tuned for around 330hp. Reliable, not hard or overly expensive to achieve, and for a 4wd car a decent amount of power for the street. Maybe a good option if you sell your car when the reverse-work is completed?

Yeah it's a bit of a pain in the arse and wallet, but to be honest my car is a bit of a lag monster at the moment, I was planning to change the turbo anyways. I should be able to get at least an easy 300rwhp, and the only visual bits will be the intercooler, exhaust and pod. The car is otherwise very clean looking and hasnt attracted too much attention.. The only reason I got a yellow was for my BOV and bald tyres which was my own stupid fault (even though it was booked in that week for new tyres :().

What have you got these days Nathan?

You can get the stealth intercoolers which uses the standard piping in the engine bay. The cooler piping and exhaust (if you know what your looking for) is the only thing in my engine bay that points to extra power. Pod as well. Even the exhaust is super quiet, so it's definately possible. That's with the high-flowed tubo and remapped ECU.

3. Intercooler - It is a genuine greddy so no issues with cut bumpers etc but are these legal?

Hi, from my experience, an oil catch can is legal if it drains into the sump and the breather is plumbed back into the intake.

Similarly, an aftermarket BOV is legal, if it is plumbed back into the intake - assuming that it meets noise level requirements, which all but a few would with this arrangement.

Regarding the intercooler, there is nothing illegal in WA about fitting an intercooler, as long as you have not altered the car's structure to fit it in (i.e. cutting into your structural cross member or carving up your front bar so that it flaps in the breeze).

Also, there is nothing illegal about shiny pipework. It will draw attention to other mods, though, and may attract a demand for an engineer's certificate and even an emissions test (although the latter is not so much a problem, as the demanding test is temporarily on hold - see other threads).

So, not much to add to what others have said. Hope it all helps. :thumbsup:

Cheers. :)

I went over the pits a few months ago when coppers mistakenly stickered me for my car being too low. I had boost controller in plain view smack bang on the top of my steering column and my apexi pfc hand controller was still mounted to the dash, the guy didn't care. Depends who you get on the day you take it but yes, having a boost controller in the car is definitely frowned upon, and if you do have a PFC controller... hide it heh.

Yeah, I'll have the hide the boost controller somewhere.. I'm also slightly concerned about the test drive, as I have read that the HKS actuator is set at 1 bar minimum? Hopefully the inspector doesnt put too much of a boot in :D

I am thinking I will just leave off the catch can until I pass, not worth having to go over again.

  • 3 weeks later...

Well, went over today and finally passed :P

6k of parts and labour later..

Was dodgy as because my reverse lights only work if I hold the gear lever slightly to the left

All the positive of the day was ruined by getting a speeding fine for 58 in a 60 zone.. the boys in blue are in my bad books at the moment : :)

What? did you actually get the fine or did you just get flashed? If you just got flashed then don't worry about it, they would have just been calibrating the camera. If you actually got the fine... complain!

That's a huge amount of money to spend to get a car over the pits without spending on handling/safety modifications.. seems like the point of actually getting a vehicle road worthy has been lost in the political legislation jungle.. flawed system indeed.

    • Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.
    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card style AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had no flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.
