Hi there
on my gtst rb25det getting some sort weird noise ( i dunno it s like rattly - not knocking- it is like loose something in somewhere noise) from near side of the engine where the turbo is. When the engine warms up sound goes away. As far as I can say there is no power or boost problems. Recent oil change with mobil1
car done 42k miles

Any ideas and where can I get this checked around west midlands?

Car is running on normal boost
Hks superflow induction
Decat
Full stainless steel exhaust system.

Thank you for your help.

If I were you , I would check all the bolts to see how tight they are around your heat shield and in that general area. The reason the noise stops as the car gets hotter could be due to thermal expansion......

Just a thought.
