Hi guys,

i have recently purchased a R33 GTR 96 and I'm loving it except for one lil annoying problem.

The whole car is stock besides the exhaust system. the car has done 56xxxkms freshly imported.

Anyways done abit of research and thought I would take out the restrictor. very impressed with the power gains but then sometimes when i shift up gears at higher RPM (7.5 - 8) it makes this weird slightly crunchy noise.

Anyone experienced this before?? to me it sounds like the gearbox or clutch cant handle the increased boost...

hope you can help

thanks :)

If it's a gear crunching you will feel it through the gear stick. The gearbox will handle a s#it load more than the 250 odd kw you are now putting through it. When you do pump too much through them they won't crunch a gear, they will destroy a gear, and that will be the end of your gearbox.. At what point does it make the sound? Is it only the sound? Also your car doesn't have 56,000k on it, so don't assume all the parts are that new..

thanks for the reply, Its only the sound. It happens when i change in higher RPM.

i got my mechanic friend to quickly test drive it and he thinks the noise is related to the bov not venting the air properly..

A bov does not make a crunch noise. It makes a pew noise or a cascading pew.

A crunch is a crunch. And if it only happens going to one gear then that gear has had a bad time.

Also if you dont have the import certificate or full service history then it doesnt have 50xxxx km

I dont really know how to describe the noise, crunch noise was the first thing came to mind lol.

it goes something like this "hhhhhhuuuuuuuunggghh" but if i change gears really fast then it doesnt make that sound

i got my mechanic to check the car (on hoist), and he said that all the signs lead to a legitimate kms. Even if the kms are not true i dont really care I'm loving the car and its immaculate.

I dont really know how to describe the noise,....

it goes something like this "hhhhhhuuuuuuuunggghh"

I heard that sound once too - 'twas in a film

Something to do with surveillance equipment.

...in "Meet The Parents" I think...

    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
    • There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.
    • yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
