R33 Problems (rattle)

[proRB88]

Hey guys,i test drove a 1995 r33 GTS-t today and i got to admit it was fun but the only thing i didn't like was when you would take off in first (i didnt try takeing off in any other gears). the engine (not to sure if it cam from the engine it sounded like it came from the left hand side of the car) would make a rattling noise it was really bad, would any body be able to help.

Best regards Vlad Adam

Could be anything, get it checked out by NRMA etc.

would it only do it with the clutch either in or out. it may be that the clutch is noisey (either the springs on the clutch plate or one of the bearings).

When i start to de-press the clutch, and take off it woiuld start to do it and then continue till i would change to second or boost would kick in, but it would not do it when the car was heated up.

If it's under any kind of load a 'rattle' like marbles in a tin is our good chinese friend 'ping'. If it's a sound coming from the 'left side of the car thats consistant with Mr Ping.

Mr Ping is visiting with his good friend 'Too much base timing'.

Make a mark on your CAS to see where you started with a marker pen, losen the bolts so you can rotate it. Get out your trusty Timing light take a few degrees of base timing out at idle, tighten it back up and see if it fixes the noise. In the mean time DONT try to make that sound anymore. If it means not driving you car till you can do this then so be it. RB25's 9:1 compression doesn't make for forgiving ringlands under boost with ping.

See how you go. It's not uncommon as an issue.

If you have a fairly modified car, the porblem could be a little more complex by the way. I am just assuming you have a fairly standard gtst.

I've got that in my car, turns out it's the intercooler piping rattling. I just got a bit of rubber, jammed it in between the pipe and the hole in the chassis and viola, all quiet again

from what i could see when i was taking a look at the car it's pritty much standerd, exept a blow-off -valve, a fool 3 and 1/2 inch exhaust system. and boost controler (valve type). some1 did mention that it was the intercooler pipings and now that i think of it the guy had aftermaket pipings, but a stanerd intercooler. so would that be it!!

And it was like a vibration with a lill bit of a rattle! (im sorry i cant really put a finger on it my haring is not that good so i had to get a trust worthy friend to come with me when i did then test drive, i could hear it but not that clear, im just going off what he explanied it like)
