if that's all you're looking to make then a 6262 will get you there with plenty of headroom no problem, I'd consider getting a precision SC61(same compressor as a garrett gt35r with a stg5 turbine wheel versus the regular "GT" turbine wheel) it'll make 350/400whp easily with a high ceiling as well and deliver fun usable spool and a great powerband. Get that hx50 back on a diesel where it belongs
the sc61 is also cheaper than a 6262!
don't get suckered into the "billet turbo" hype...
