hi ,
iv got a genuine garret t4 with a real big exhaust housing on with external wastgate, im thinking of useing this turbo soon for about 450bhp, and i want to put the ex housing back to a 0.63, with internal waste gate.
my question is will my 0.63 housing from my t34 fit,or dous the t4 have its own unique housing?

thank you....mart
