3.1L heating problems... again..

[geeves]

Those EGR readings suggest any overheating is not due to the turbo

[holden]

my exhaust dump is 2.75", after taking it for a dyno tune this became evident its not big enough for the new turbo.

so i have upped the dump pipe to 3" and the boost is a little later and is lower at high revs.... so far this seems to have fixed the problem.

Hey Jasin,

Can I buy your old 2.75" exhaust dump if its still in one piece and if it will fit a 2.8 turbo.
