I used the turbo, intake, fuel system, and Harness from the 2.5. it is on the factory 2.5 ecu just without the exhaust avcs hooked up. The car is throwing no codes. So I don’t know where to start with diagnosis. The 2.5 blew because of a fan that stopped working there for it over heated and spun the rod bearings. So whatever the problem It didn’t cause the 2.5 to blow.
