Im thinking of changing the turbine on my gt28rs to a t3, is the spacing/patterns of the bolts the same for any t3 turbine housing?

and also do any of you know a site to order just the turbine section? im looking for a .82 a/r

 

You could probebly get it from http://www.atpturbo.com/ Spacing is the same from all T3 flanges, but why do you want to change it?

 

wana change it so i can run the manifold downpipe i already have (all t3 flanged), i cant use adapters either cuz the wastegate dumptube wont match up
