    stock bottom end possibly forged pistons what do you think? Worth the time money for them. Wanting to make around 500rwhp. Heads are 487s cleaned up. Cam summit 1104. Biggest question is will this turbo be too small? Or is there a better option for some reason? Thanks for any input guys

    Its a little small on the compressor side but depending on how much hp the engine makes NA, it may not take much to get 500rwhp. If you're not trying to set the world on fire, it'll be just fine and spool quick!

    IIRC the 66mm compressor will support about 650-660 fwhp @ 14-15 psi which would get you to your 500hp goal if it makes 330 or less n/a. The compressor will be very close to maxed out though. I ran the same turbo, but with a 1.10 t6 on a stock 5.0 sbf and it worked very well.... was making boost sub 3000 rpm even with a fairly loose converter.
