Regulated return is a must, I think you'd want a bigger turbo but not sure on that one. Stock fuel wont flow enough for those though. I'm getting ready for a 190/30 upgrade myself, and am going to do a stage 2 turbo, regulated return. Mine is factory cam, studded, stock bores, and will be running the stock trans till I blow it up.

Kc stg2 would be good minimum. I ran similar setup on old truck. Get some ficm tuning done to truly get full results of upgrade. Good fuel supply system is mandatory, I built my own (former ford fuel system engineer) using a aeromotive A1000, filter housings etc. A big fass would suffice plenty well, regulated return would be a plus but blue spring on stock housing minimum.
