A fairly commonly used way to make 550-600 daily driver would be an injector with a 200% nozzle and at least 300cc.
a single turbo in the 72-76mm range. There is a s474 floating around from Borg-Warner I believe that seems to match 300/200 injectors VERY well.
A fuel system utilizing dual walbros, dual stock pumps, A1000 (or equivilent Fuellab pump). 5/8 from tank into first filter, 3/8 from there to heads.
A transmission similar to a BTS, dont think I would trust any of the local shops that claim they can.... that doesnt cut it past 450hp. Leave it to the pro's, you get what you pay for.
ARP studs, Chromoly push rods of some sort, something better than 910 springs (comp cams has another option, just dont know the part number).
A modded IDM
EXTREMELY GOOD TUNING
Dual oil pumps of some sort. BTS, Gen3, Terminator, Stealth are some options
That right there could make 600+ on a dyno and be tuned to run sub 500 most of the time. If you truely want the 700hp that your title states then I would add around 10-12k for a full motor build to slap all those parts on.
