The Mafia

put the stock one back on

well, I bet its the gaskets between the turbo and manifold. Nismoid is right, the head to manifold gasket makes a tractor sound. The Manifold to turbo gaskets make the high pitched sound. How do I know? Because mine is doing it, my studs are stretching and I need to keep tightening them. There is even a little brown spot where its leaking. It sounds like a kettle, or like how the redneck bushman put 2 gunm leaves together and blow through them and make that stupid sound. Thats what happens when the gaskets are loose - they make that squeal. I'm in the process of removing the turbo and changing mine too. Bumblebee, you may say you have done 1000's of cars, which I doubt you've done 1000's of Turbo charged Skylines, but do you hae one that has had a turbo upgrade, makes some power, and is actually doing it all the time to know what you're talking about? I doubt it.

do a sensor check on the powerfc hand commander

no, there isn't

yeah bet but AFR's at the given values are only 12.4:1 Thats probably less than 5% difference to say, 12:1 It doesn't make that much difference hey

well my AFRs were only at 12.4:1 when I made that power. Also, where else would the fuel go? lol.

my 555s are at 78% and making 314rwkw

what your saying is "how long is a piece of string" Need to know: Compressor Cover AR Compression wheel diameter Compressor Trim Turbine housing AR Turbine wheel diameter Turbine Trim

hey mate, can you port the new one perfect, and then cut it up and show us what a real port job looks like? lol

you know, thats not a bad idea at all would prevent heat soak through the burnout stage

Do the R34 GTR's come with N1's as standard? Thinking about buying a 34 GTR

lol mate, you should patent that idea - no one has ever thought of it. Actually, request a sticky, as its never been thought of here! lol

LOL @ anyone saying the rev limiter would have stopped it. Of course it doesn't. All it does is cut fuel.. If the engine is being forced to rev harder, then nothing is going to stop it..

I'm tuning this exact same setup in a GTS4 next weekend actually.

those cutouts are really awesome, thanks for that.

what sort of powerfc do you have?

hhmm, not a bad thread. Will remember this.

I managed a 314rwkw run, on the 0.63 rear on the 3037 (3076) but that was ringing its neck. Was only on 18psi boost too. But bare in mind that is with water methanol injection. Curve looked like a V8's.

so many make the mistake of picking a turbo before they pick their power target. Pick a power target, and THEN ask what turbo would be good for it. Any other way is a hopeless way of doing it.

yeah mate, waste of time having a ATMO bov anyway. Put a stocker on and never look back. I'm running 400+hp at the wheels, and still have the stocker.

yeah its a low mount, standard manifold.

might want to search this site, it has been covered about 5,000 times.

well, I Have a RB25 and I am running a GT3037 with a 0.63 rear, and water methanol injection. 314rwkw a 18psi. On a 2.2 you should be right, just not sure about the head breathing though.

nope, he's wrong. My mate with a R32GTR and brand new engine, stock turbos made 220rwkw on a powerfc full tune. 150rwkw sounds about right, maybe a little more but not that much. Aftermarket ecu makes a big difference. Get one.

ummm, thats all you are going to get until you upgrade the engine management
