also the fan blades were they essential to cut? i heard if you use a longer silicon hose on the intake side it raises it just a lil bit more and u dont have to cut... but i spose ill find out soon

btw ur car looks exactly like mine same filter n shit

For me, yes they needed to be cut.

There's about a 1-2cm gap but it's definatley clear.

...and the pipe is changing colour, I'm gussing because it's touch the heat sheild stuff on the bonnet...so i wouldn't want to raise it any higher if possible,.

that goes to the boost controler and the wastegate, if your looking at the same part i am, the hose thats holding up that loose clamp on the cooler pipe. ...its pretty important lol perhaps you can plumb it somewhere else though? just needs to be before the throttle body but close as possible is better to get accurate boost signals. someone enlighten us please

The little pipe needs to be used.

That's where the actuator (that controls the little outlet door on the turbo) gets it's pressure reading from.

If the pressure is to high, it opens up and lets some gas out so the turbo won't spool up as much.

If you don't attatch it, there will be no pressure reading at all and the actuator will keep the door on the turbo shut to try and get boost up and reach the 7psi level.

Therefore, you will have unlimited boost ! BAD !!

Your little needle will go right off the chart and turbo blades may detach...

You probably can drive around just don't accelerate to hard and your boost won't go to high.

Enough for you to drive somewhere to drill a hole and weld a nipple on there for you and all will be sweet.

...and if your gunna have a front mount, at least get a bleed valve !

Yeeehar !

Just got my car tuned on 12psi using the bleeder and a Power FC, and FMIC of course.

frigin hell!!!!

Scary shit and I'm only on 194 rwkws!

Good luck

I would do what Birnie said... Maybe better to take that pipe off and bring it to a place to weld a nipple on. That way you can make sure all the metal filings are all out of the pipe, before it goes back together.

ok guys i found a spot to put it.. my mate rekosn he puts it where the pipe going in to the pollution canistor thingy from the intake plenen.. seems to work i guess but i havent driven it soo i dont know? btw its all done :D biggest headache and soo many hours in it

I honestly have know idea what that black thing is and if it has pressurised air coming thru it.

Take it for a drive, if your boost levels seem to max out at the same spot as before the cooler kit....ie 5 and 7psi....you should be set.

Now go and spend $50 on a bleed valve..tehe

Hey Birnie, The olny problem I forsee with your actuator feed is that the acuator will get vacuum from the plenum when the throttle is shut. I have read on this forum that the acuators don't handle vacuum too well, and the best thing to do is weld a nipple on.

Here's what I did. This is my pipe coming from the cooler.

hey. i was wondering what is the best way to rust proof a hole that you make?.. just paint it with rust proofing paint?. or is there something beta so it dont chip of when a screw goes through?.. thanx

Hi, i cut the whole with a circular (metal type) saw on the drill.

Then used regular rough wood sandpaper to smooth it off until it was safe to touch with your fingers.

Then painted with a generous amount of rust paint.

I has it like that for years with no issues (and i have seen bad ones with rust galore)

I was going to get a piece of garden hose and slice it down one side for the full length of the tube, and then wrap that over the cut to help stop any damage to the pipes, but there simply wasn't any room after the cut and by that stage, i didn't give a crap anymore :ninja:

Wasn't going to re-drill bigger. Good luck!

thanx so much for that help.. i was thinking of puting some type of rubber around it and glueing it down or something so the pipes dont scratch.. but, so hard when doing small holes... ill use rust paint.. thanx again..

and yeah.. old thread coming back at you :ninja:..

Double check 'Post #8', then the 3rd pic.

It's a pic of the intercooler hole i drilled from inside the engine bay.

You can see the hole is below the bottom screw of the original washer tank.

All good

Problem is that on my R34 there's some type of cooler (my guess is for the power steering oil) mounted in that area. It's not possible to move, the piping is hard, and it doesn't allow me to angle the original tank. I solved it yesterday by mounting a smaller tank inside the engine bay.

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
