has anyone ever had this?

Gregs GTR is making some weird noise, and its got so loud now it almost sounds like a V8... the exhaust is brand new, down pipes seem fine

do the 32 manifolds have a habit of crackinG?

it boosts fine

any other ideaS?

or maybe a cracked elboW?

would a leaking elbow generate enough heat to crack the seating?

IMO yes it more than posible but i have not seen this personally

 

[Marky_GTSt]

Is it possible that its one of the gaskets thats gone? , Would be nice as its rather cheaper to fix...

And they do normally get louder over time too, Had a 200SX in with similar probs, No power and slowly getting louder, Fresh gasket on where the turbo meets the manifold and that cured it all... Also worth looking at the manifold bolts, I have seen quite a few turbo cars with bolts broken or missing from there...

If it is the manifolds i have a set sitting in the shed for a small premium:chuckle:

I would go for gaskets first, but you will find out as you start to remove the turbo's

Its common for the elbow nuts to come off and allow leakage there.

Even a slightly leaky cat-pipe gasket can sound pretty bad.....

My mates R32 had a similar noise, sounded like a tank, was a blown gasket, exhaust manifold where it joins the turbo.

Manifold to turbo gasket. Guaranteed

Manifold to turbo gasket. Guaranteed

turbo off i take it?

 

[leggus]

turbo off i take it?

Absolutely

 

[leggus]

Its the big rectangular gasket on the left of the picture that will be blown..

 

[Pikey]

Leggus is correct

 

[Mookistar]

spoke to ron and he agrees too

think we are gonna luzz some 34 tubbies on there until he can afford something better

thanks for the input

yep, them rectangular things, burnt through mine and had to replace them. Put it off for awhile though because, truth be told, I rather enjoyed the obnoxiously loud roar the car gave off. Better not let it slide too long though - the scorching hot exhaust gas leaking will warp the flanges, and skimming the flanges flat again just adds more grief to what is a more or less straightforward job.
