Aftermarket Turbos,are They Legalish

[GtstCoupe]

is any form of aftermarket turbo legalish on r33 ,and would insurance for example with justcars cover you anyway.

and what turbos look stock or use standard heat shield.

regards Gtstcoupe B)

What turbo looks stock? A highflowed stock turbo.

Besides that, to the best of my knowledge there is no ADR compliant aftermarket turbo kit for a skyline in Aus. I stand to be corrected though.

There are a lot of turbos that can look legal, Hi flow is the best from that perspective as it is all in the original housings, then there are the HKS 2530 2535 2540 and GTRS that all bolt on in the shock position and would I imagine fit under the heat sheild with a little mucking about, Another option is the Apexi AX53B70 P25 which is similar to the HKS ones, there are also a few garrets that are around the same specs and sizes the HKS ones mentioned, so there are a lot of fairly inconspicuous turbo choices around! As for the legality Im not sure as it would depend on the state you are in!

Hmmm... legalish...

Is that when things are not legal but also not illegal as well...?

What sort of criteria are we looking at to decide, if a turbo is legalish or not...?

[GtstCoupe]

yeah i am in vic anyway, just dont want to get hassaled for having a diff turbo, than stock loooking

[paulr33]

most of the other parts you fit with the "bigger turbo" aren't legal and you will get defected for if they aren't hidden. things they will look for:

1) unplug afm and see if car stalls

2) check for ecu under kick panel

3) pod filter in engine bay + aftermarket intercooler

4) boost controller (coloured tubes and wires going to turbo area)

5) exhaust too loud / and or black stuff on rear bar = dead cat

so you could fit a hiflowed under the heatshield and it will be fine and no one will be any wiser, but if you have a boost controller clearly visible with a pod and fmic then it wont mater as those are illegal/defectable

atm i am using my airbox with my cooler, boost controller well yeah need to hide him better

In NSW, there are a number of modifications that are 'owner-approvable'. These things include

exhaust (within noise limits), wheels (within size limits), suspension (within height limits, afaik

you can't change the geometry and you can't cut/weld stuff).

There are probably a few more, the place to check is the RTA or your state's equivalent. These

things are also changing (something about a 'signature note' on exhausts).

Any other modification (in NSW) needs to be engineered. So in NSW you need to have turbo

changes engineered. I understand that Vic is _more_ restrictive about mods; so the best thing

to do is check with your RTA equivalent.

Justcars have some interesting wording; they let you 'nominate' any type of mods (like, for example,

ECU) _but_ they say that it must be a 'legal modification'. Now to my knowledge using turbos

that are different-to-stock requires engineering to be legal, so without the papers they could

very well turn around in the event of a crash and say 'no, you're not covered because it's not

a legal modification'.

That being said; I had occasion to claim on my original GTR after I put it in a ditch. It had pods,

ECU, boost controller, exhaust - three things requiring engineering in NSW but that I had no

certificates for. They paid up with no fuss at all, and in a timely fashion. The best thing to do is

to ring them _before_ you make the mods, tell them what you plan on doing, and ask whether

you will be covered or not - preferably in writing and get the answer in writing

My understanding of things, which is from a NSW perspective (but the draft oz wide mod rules are very similar to these so watch out those of you from other states), is that the big problem is proving ADR compliance, specifically ADR37 (which includes drive cycle testing).

Factory turbo options comply with ADR37.

Some of the more common turbo kits *may* have been put through the testing if the company putting the kit together have gone to the right amount of effort. Since we are talking imports, then it's unlikely there is any "legal" (as in ADR37 legal) kit for a skyline.

Anything DIY is almost certainly not legal. Even though it might pass, it hasn't been proven to.
