Cutting Whole Under Water Bottle For Cooler Piping


Recommended Posts

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

Edited by Ricos

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

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

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
