Performance Questions 225 vs. 360

Here's a low budget turbo slant build
Super six intake $100
Holley 390 or 500 two barrel modified with hanger 18 mods $150
Pishta U bend pipe and flanges( high end price) $150
Walbro 392 fuel pump $100
Mallory 4309 fuel reg $ 100
Cold side piping and coupler kit under $100
Hotside piping $150 maximum
Carb hat $150
Grand national turbo or similar model $250
Different lines and fittings $150
That comes to a grand total of $1400 alot of parts can be found cheaper
I'd also get a a/f gauge but one isn't need but helps a ton when it's time to tune
This setup would be good for about 10 psi of boost and would probably net around 250hp
