r32 gtr owners.

At this stage I'm not sure, considering taking this oppurtunity to get out of the game for a while, as I've owned the car for a year or so and only done 5000-6000km in it its hard to justify how much money I spend on it.

Have got a few options but might have to deny the dream path of glory

[Micko]

Hey there Driver - the real question here is can you afford to be replacing turbos when you get your car?

It seems like a bit of a lottery as to how much boost they will hold - I was running 14psi when one of the turbs spat the wheel out the ar$e end:Oops:

Had to buy some 2530's to fix the problem:elaugh:

Steve is a total nutter (j/k steve)...oh, & he owns a performance workshop so he can repair things a little cheaper since he does all the work. Keep pushing em Stevo you'll get those turbs soon enough:D

[Driver]

hey micko

Thats exactly why im asking because i wont be able to afford new turbos probly untill end of next year the way things are looking as i will be looking to buy a house sometime soon.

Im hoping i wont grow bored of the stock turbos, but i know i will.

[HKS EVoLuTiON]

well back wen i first got my car it had the stock turbo's on, it had pods and a mandrel bent exhaust and rps tip and a boost controller, it was on 14psi but i dont know if they would have lasted much longer

[Nugget_GTR]

Yeah i run 16 on then but im unsure if they are completely stock turbos have not had the car that long and still finding stuff out about it, was running on about 16 when i first got it ad 10 on low.

On this question how much boost should the fuel system keep up with?

cause just the other night my electronic boost controller scewed up and i wasnt really paying attention to my boost gauge but i thought to my self damn the car seams to be hammering and out of the corner of my eye when i accelerated my boost gauge went past 20psi and i was like ahhhhhhhhh but the wired thing is it wasnt detonating was running nice and the turbos seem fine and it wasnt just for a second it was on 20psi of a good haul... but i was so worried afterward. would the stock system be able to handle something like that?? or would there be something no standard there?

its really a lucky dip when getting stuff imported.

[Amaru]

but the wired thing is it wasnt detonating was running nice and the turbos seem fine

As they say, by the time you can audibly hear the car detonating from within the cabin, its too far gone.

We managed to squeeze 210awkw out of mine before the fuel pump started maxing out. Some get a little more, some get a little less.

[Nugget_GTR]

mmm well thats ok cause i have an after market fuel pump know that for sure apart from it saying on the engineering papers you can hear it

but damn if it was detonating im sure the engine would have suffered but there is no signs of it, engine still have good comp... or a i was just really really luck i got a new controller in there since so no more going above 15 for me

[N I B]

119.35mph over the 1/4s not bad for stock turbos and dumps so if they last they are still fun.

[BoOsTeD_RB26]

I hope you got an 11 with that MPH

[N I B]

12.0 -2.1 60ft on shitter cheap tyres but i have some good rubber for her now so she can get her 11 plus it has no AFMs etc now helping it make a bit more hp also.

[BoOsTeD_RB26]

Nice work!

[Sneaker]

Clarification: So 1bar worth of boost on the stock turbos seem to be okay? Is failure past this because of the actual boost or the fact that the turbine shaft speed is too fast causing delamination?

The reason I ask is because I am about to undertake up grades in the way of a competition dump pipes and y piece as well as a retune on the dyno. I already have a larger free-flowing FMIC and pods. What worries me is that with all these mods I will have less restriction in the system and therefore less boost. If I then up the boost to 1bar I would imagine the shaft speed will be greater than a near standard system with 1bar.

Am I on the right track? If so, should I tune for 0.9bar or even less?

So is it the boost or the shaft speed?

[Ronin 09]

I'm running 1 bar with turbo back exhaust, PFC, cams, stock airbox 255rwkW, 8200rpm limit

What dump pipes are you using? Are you running the stock FMIC?

[Ronin 09]

Dumps are Trust split dumps, exhaust Trust Power Evolution II.

Stock FMIC

So is it the boost or the shaft speed?

Just jammin here but I assume heat would be the cause. Differences in thermal expansion between the metal shaft and the ceramic exhaust wheel could cause it to detach...

Whether the heat is a result of exhaust restriction or excessive shaft rpms would depend on the setup I spose.

If so that is good news, as taking out restrictions should also drop the thermal loading. I am putting on 9in long dumps that are ceramic coated so it should keep a lot of heat away from the turbo and engine bay.

Does this sound right? Can anyone concur?

[Boosting]

i ran 18psi on them for about 8 months before they died made 247kw at the rears on that running rich as hell..

is that with stock fuel pump?

[Ronin 09]

yes
