I know in our gt40's you will find no turbo's, but my other car is an xtr4 with an audi 1,8 rs engine with a garrett 4 turbo watercooled with 250/350 hp.
I have toubble with the original audi gasket and a selfmade redcopper gasket, they will blow away after 100 km and revving the engine to plus 7000 rpm.
I made extra cooling the headers by a nacaduct.
Taped the exhaust, don't use a db-killer but 90 degrease bended pipe.

What i want to do is milling a hole in turbo and the adjestdment piece of the header and put there in a pipe of 10 to 20 mm lenght.(sorry for bad english)

What is wise?

Regards,

Lucas
