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...

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.

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?

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

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...

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.

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.....

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.

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

      Depends how low and tyre size. Should fit with natural camber, skinny tyres and rolled guards.

      Was planning on getting an R35 MAF and the adapter, should this be okay? Also any idea where I could get my hands on an intake pipe?

      I mean yes, if you're starting from scratch on an unknown engine yes you don't need to be doing all kinds of math in the background but if you're doing relatively minor changes like AFM + injectors + boost up with some aftermarket turbos it takes quite a bit of math if you want to do something like maintain OEM fuel + timing tables but compressed and then a bit more load scale up top. I think I've spent too much time working on big engineering nightmares though so I'm a big fan of trying to constrain the scope of whatever work I'm doing as much as possible and trying to get it right before moving on. For example, a local owner just did the usual E85 + single turbo conversion to his R32 GTR and nearly burned his car to the ground doing some spirited driving up the local mountains. Turbine is unshielded and too close to the hood insulation. It's tough to balance "just get the project done" and "seemingly small details can cause massive setbacks I'm not willing to deal with".
