Problem:

My R32 GT-R developed a rattle this afternoon. Took me a while, but i've narrowed down the conditions required to make the noise.

Revs have to be over 2500.

Boost has to be in the few marks on the guage just before 0. As soon as you go into positive boost, the rattle stops.

If you back off the throttle completely, the noise stops.

This happens in all gears at all speeds.

Stock turbos etc.

Does anyone have any ideas on what the noise is likely to be?

Anyone in Melbourne who's near the CBD is welcome to come listen if you think you can figure it out..

Sounds very similar to the rattle I heard when my 32 GTR shat a big end. It starts as a small rattle and gets bigger from there, I could feel taping on the throttle to. Get it looked at by a professional workshop asap as if it is a big end and you don鈥檛 stop driving it asap the damage increases exponentially. Sorry for the doom and gloom but that was my experience with exactly what you are describing. I ignored mine stupidly for a week or so and ended up cracking the crank...

I'm planning to get it looked at this week (it's not a daily driver)..

Anyone in Melbourne have a recommendation on somewhere that does good work but doesn't charge mega $$.

I'm after getting it fixed, not producing huge HP.

Feel free to PM me if you don't want to post recommendations :thumbsup:

    • Chrome surrounds back on and polished up, no idea why some knob would prime a single piece 馃檮
    • Well, in the same way that you can't tell any SUV from any manufacturer in any size category from any other one, "sports" coupes now all look identical. Stand back and squint your eyes and the Supra and the 400Z and the GR/BRZ things all look the same. I was just thinking last night, when sitting behind a Subaru CrossTrek, that I have no idea what it is, how it differs from an XV, or a Forester, or an Outback, or anything else Subaru offer, and I couldn't tell if it was supposed to be small, medium or large. I contrasted that to the good old days, where a HQ Kingswood had familial similarities to an LJ Torana, but there is no way that you could confuse them, and how a bit later, the HX Kinger and the concurrent Torana and the Gemini all had familial similarities, but you still could not confuse them. Ditto the ugly Fords and Chryslers of the era. But now, a RAV4 looks like a Kluger, looks like a Yaris/Cross/whatever they're calling those stupid f**king things, looks like every other Toyota that's not a Camry/Corolla sedan.
    • The Prelude doesn't look that bad without all that lens distortion in those pics. Makes it look disproportionate when it isn't. Actually I kind of liked it at the Osaka Auto Messe earlier this year. 
    • Pour in the highest octane, non-ethanol fuel you can get and see if the readout changes. If it's dead bang on 11% then I would question the sensor. Another quick test, just take it out and run normal (in an american accent) gas-o-line through it and see if the sampled ethanol or lack of changes.   United E85 here in the land of drop bears does vary a bit, I've had as high as E87 (could be water in their tanks too, who knows)
