around 15-17psi.

There are THAT many people making 250rwkw on stock plenums using 15-16... that IMO, there is absolutely no need to change it.

IF you want... by all means do... but the money can be better spent elsewhere

People with plenums havent posted results that look much different to the equivs running stock items.

Thanks for helpin me out Nismoid, top bloke

I've also heard that everything is fine as i've got but if the boost goes up the turbo changes along with fuel pump and injectors. Last thing how much roughly is it all gonna cost, cause i'll just save up the bulk and get it all done. How hard is it to do. ie easily to reach or fiddlely. I should be right to do it myself or would u advise against it?

Turbo $1750.

If you have a couple mates around one arvo you should be able to remove/fit it.

Its just time, removing parts, and making sure you remember where they came from.

I've pulled my old setup apart, which was far more involved and it took me about 10 hours on my own in total, and im hardly skilled with a spanner.

So with help you should breeze through it if you do it over a weekend

Or a workshop might do it for $400.

Remember you gotta send the turbo off for hi-flowing and that probably takes a week turn around or there abouts.

Also, replace the manifold studs, each one of them, and the manifold gasket.

Saves you doing it later on as its likely to die.

So overall, turbo + studs/gasket etc its around 2k including the slab for the boys if you DIY... or 2.5-2.7k if you dont.

Cheers

Thats with no injectors or fuel pump hey, how are they with fitting?

Theres a turbo place in port kembla that just gives u a turbo they've high flowed and u give them your old one and they get it ready for the next bloke who wants one... The GCG hi flo.. its just a high flowed stock turbo isnt it?

Hey Nizmoid?? And to imply hidden agenda, grow up??

Dude out of all the turbos on the planet why GCG there are so many options?They dont make em, they fixem/rebuild em?Never will they be better than a built/made high performance turbo built for high performance

and not just FixXed to take a bit more.

Imply! Dont think so! your response was admission by default!

Grow up! Naa man i dont think so the B.S starts when you turn into an adult, Kids Rule!

Mate no one cares what u say anymore, your a drop kick that thinks he know everything... If you did why are u posting on here asking questions insted of answering em?

One reason why the GCG highflow is recommended is because it's a ball bearing highflow rather than the bush bearing that most places do.

There are plenty of threads discussing the difference so it doesn't need to be done here but some of us think the ball bearing ones are much better.

Also GCG have been doing them for a long while and they have gotten better with practice.

There are lots of different turbos out there. The fun is in figuring out which one will suit you and getting out there.

Oh and also, with cams a couple of us are making 250+rwkw with less than one bar of boost.

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