Hi guys I have a question about the flanges on turbos,are the flanges all the same size throughout the different models?the flange part that u bolt the turbo onto the manifold.So u have t25,t28,t3 and t4 are they the different flanges?

In short "No" there all different to suit each turbo style eg T3 pattern requires a T3 flange
some of the common types are T25/28 ,T03,T04, then there is open and split pulse
hope this helps
cheers anthony
