+1 for leave them

sure people will tell u u can make more power etc without coolant running through everything, but if bits r cold on the intake ur car will have bad fuel atomisation etc and might drive like a pig till warm. remember carby cars often run a heat riser tube off the exhaust manifold to the intake for this reason.

reminded me of the "mod" where u bypass the throttle body coolant hoses etc and people feel a gain in response and power etc! lol kinda odd considering the whole inlet manifold has coolant running through it!

hehe, at least ur doing it for logical/sensible reasons :)

as for getting rid of em, yes its a mess under there, and its been a while since i had a good look with a plenum off, might have to try and nut it out, or just change all the hoses to save headaches.

i had one in there let go, it was an absolute prick to change!

When I had my head off I redid some of the coolant lines by removing some and reconnecting others. It's a bit hard to describe it all but the easiest one to do is the throttle body coolant one and rejoining it elsewhere. That's one line you can piss off, don't need to worry about a buterfly sticking shut in Australia's climate.

I have had many let go over the years on my other 20's. its bullshit, And i really think they are not essential.

I will replace them all new if no1 knows, but i have heard of people removing/blocking a few.

Maybe because of the age of the lines, or becoming blocked?

What would nissan not know that you do?

This is about as far up there with mods such as filling the chassis rails with foam, or looping the battery fumes into the intake...

Battery fumes into intake?! :) rofl

Please ellaborate!

Kinda reminds of me of a wrx owner i was on the phone to, who wanted his ""screamer pipe" hooked up to the intake to his turbo"

Yes epic LOL

I explained u only do that if u want a nice fire in the engine bay and kindly suggested to bring it past and i'll have a look what he meant exactly what we might be able to do for him. He never turned up tho funnily enough! :(

Generic foam in chassis rails wont do squat, but u can get stuff more specific for the job that does apparantly work, off topic either way.

      Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.

      Recomended Coolant For Gt T R34

      By silviaz · Posted

      What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.

      Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!

      R34 4 door side skirt identification

      No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
