just a quick question people but what is a owen developments gt3076 turbo good for with supporting mods it will be going on a sti8 bottom end with cosworth head gaskets v4 heads and 14mm head studs,along with other mods,but just trying to get a general figure of what the turbo can run cheers in advance

 

You may discover that the turbo isn't right for your needs. A better way to go would be to work out the kind of power output v spool requirements you're looking for, then spec the engine and turbo to suit. Almost always, just choosing to use a unit you may have to hand results in disappointment.

What kind of power are you after?
