Had some turbo bits laying about, and time to kill , so I decided to fit the .47 exhaust housing to the T04 and see what the result was. And the result is (as you would expect) that it comes on boost a lot sooner than the .63 ..and makes it heaps better car around town and at country speed limits.
Best thing I ever did.
