I have the exact same package as frankenwrench. GTX3582 turbo with intercooler, 110 pump, stage 1 injectors, ARP head studs.And I assume you just have a factory ats wastegated setup, no intercooler? I'm finding several options available for turbos and coolers, but I think a stock turbo w/wastegate no intercooler is all I need.
I wouldnt worry about studs unless you are planning a build with big turbo...pump and injectors. Stock style turbo with adjusted stock pump and injectors makes respectable and very dependable power. IAh, well I'm trying to steer clear of head studs, mostly because I don't want to crack my engine open just yet, looks like stock turbo is my way to go. I still have stock pump and nozzles.
