R33 Boost Problem And Smell

[R33_SII_97MSPEC]

Hi Guys,

I have a series 2 r33 gtst that i love to bits. Had the common boost problem that these cars seem to get (5000rpm starts to miss, jolt etc). I have had the coils out and they look ok and replaced the 1.1mm plugs with 0.8mm plugs. Made a difference at first but the jolt has come back. Think the coils are dead so i'm currently about to buy some spitfires. Anyway that aside i have started to notice lately that when i give the car a bit of a kick sometimes a bit of a smell wafts into the cabin, like a rotten egg sort of smell. Any ideas?

The smell is only there sometimes and only comes on when i give the car a bit of a push. Any ideas would be greatly appreciated.

Cheers.

Is it a rotten egg or BO smell?

Rotten egg sort of smell could be clutch smell, your clutch might be slipping a bit.

Rotten eggs could be coolant from a busted heater core. Just a thought as i had this. WHen you boot it the pressure increases and any leaks will be amplified. Look for water/coolant on the floor and behind the dash.

Cheers guys, i will have a look for a coolant leak when it is not pissing down with rain (which is great by the way!). The smell is more of a rotten egg smell than a BO type of smell.

Is there anyway to test the clutch at all? When i press down on the clutch the revs change ever so slightly and then when i release they go back to how they were before depressing the clutch. Could this be a sign toward anything?

Really appreciate the feedback guys.

Cheers.

Have you changed the gearbox oil recently? If so it could be this and the smell will eventually subside.

I have heard that an egg smell can meen a coocked cat. Not sure if this is true iv just heard it before.
