Cutting Whole Under Water Bottle For Cooler Piping

[Ricos]

i was reading around and im pritty sure i read somewhere that, cutting a whole under the water bottle on the drivers side in the engine bay on a r33gts-t is illegal and defectable?

is this true?

if so

wat do u need to get around it?

engineer certificate? or just the removal of the piping / FMIC?

wat does it cost to fix up usually?

yea this is illegal and if a cop pulls you over can defect your car along with request you to get a engineers cert..

95% of lines have it and about 2% of us have engineers certs...

[Mavric]

also it costs upwards of 400 bucks to get an engineers

bull shit it is legal, cops just don't know what they are on about. You are not cutting a hole int a structual member it is a guard, not the crossmemeber or chassy, therofr it is legal, but you will get pulle dup on it, and have to do a lot of explaining. I am a mechanical engineer and have been pulled over before and had to argue and go to cort, IT IS LEGAL as long as it is not a structual component, and the hole in the guard is not structual.

Someone i know recently got done for this in a silvia.

He went to vicroads, told them it was a pre-1996 car, and they cleared it on the spot.

This was only last month.

Seems like everyone is confused about the actual ruling.

[WogsRus]

yeah most GOOD workshops will clear it, a guard is not structual in any way at all. so it's fine.

any modification forward of the firewall is to be engineered...

sux balls it cost me $1500 cas one cop spotted it on my car...

not sure i understand what the pre 96 car had to do with it

so is it legal? lol is it actually writen any where in writing ?

wats the go with engineer certs, do they fix it or just give u a peice of paper saying ur allowed to have it?

I would say that its not a structuralk component, its the inner guard. But reality is in the age of deformable front ends they may have a point, albeit weak. If it cant be bolted on or off then its part of the chassis is the argument i have heard.

you can also weld a gay ring around the whole and that passes as well...

so if i get picked up....and they dick me for the hole

do i need to get a engineer cert....or can i cover the whole and it will pass?

wats the story on that...could someone clarrify with a bit more detail?

thx

if u put the ring there urself and u get pulled over say they engineered it and they will ask for the paperwork u wont have it.. they can make u get one anyway seeing as thought an engineers only lasts 30 days..

not much you can do about it thought...

[Mavric]

also on that if i am wrong please let me know but the engineers cert i got less than a month ago says valid for 30 days.. and as i said it cost me 1500 bucks

Its illegal.

You are required to weld a supporting ring around the cut made.

Mine has been done this way so that i wont be having issues with the engineers.

Until you are a VicRoads approved Engineer, whatever you "think" isnt good enough.

[Coupe-This]

an engineers cert only lasts 30 days?

whoa, thats a rip off.

must goto work and make some 3" 10mm support rings might be some demand for em ... interesting

GTR's have the hole there from the factory. As long as it's neatly done i'd tell them to stick it. Feel free to come have a look at mine sometime to see how it's done. Think from memory it has some sort of ring around it.....

Isnt there a thread on this exact topic on the same page in the vic section?!

MATE i'm an engineer and do a hell of a lot more when it comes to structures, and cutting that size hole in the car IS F U C K all.

After doing some simple calcs, if at 60 the car was to impact a solid wall, taking the stress and strain modulous of steel and some basic geometry, the differance in the hole there and not there was 0.0045%.

THE HOLE DOES NOTHING FOR THE CARS STRUCTURE. If you hack up the hole they you do introduce a stress point in the car, yess agreed, but the difference is insignificant. TRUST ME.

All an engineer is going to do is tell you to weld a ring arround it to minimise the possability of a stress fracture accuring in that spot. NOW if you ahve a stress fracture that accurs at that point, you have a lot more to worry about as there is more underlying problems with the car.

[R31Nismoid]

So basically you've just backed up what i said.

It must be supported

Funny how we ended up at that point when you said there was nothing wrong to begin with. :sorcerer:

Go read both your posts, one you say its not illegal, then you go on to say that there should be a supporting ring welded.

If it was legal/ok why is the ring needed... OH... wait... you already answered that one aswell.

Can we rest this topic now we've established that it is required, and that it is illegal unless correctly supported/approved ?

I mean, that is came up in posts 10, 12 & 14

lol but it's the in topic at the moment, there's a new tread about it like every week
