Which turbo for a 500hp 273?
Do the Math.....and tell me how many CFM.......YOUR 273 is gonna flow before you turbo charge it......and why would you install a $4000 turbo system on a car to increase the power 100 hp/100 ft lbs?
Then.....I am going to tell you
THE PROPER turbo for your setup will make 500 HORESPOWER at the wheels on 7 psi.....which in terms of boost is SToopid low.
You can get a smaller turbo and try to overcome all the adiabatic ineffiencies how ever you choose.......but its gonna boil down to:
YOU NEED 70 Millimeter compressor inducer and a 76-80mm turbine exducer.
