wtb: t3 turbine housing and elbow deal off the 84-86 turbo coupes March 04, 2015, 05:12:09 PM let me know what you have, I got a turbo but its got a t25 turbine housing on it and I need the t3......or, if some one has a good t3 could you pop the turbine housing off and measure the diameter of the exhaust wheel for me? the turbo I have is 56.5 mm wheel on the exhaust side......it may not even work out for me to swap the turbine housings.....let me know!!
