Im going to get a precision sc61 and I talked to art and Im positive that this is what I want to make 500 hp no prob plus from what I know they have the best flow rate and they are more efficient this will be going on a fully built ls with a fullrace kit plus my turbo in a light *** EG let me know what ya think.

 

Definately will be happy with this turbo, Art will take care of you too. That turbo has made some awesome #s on many many cars. Good luck.

 

thanks man I hope this is the turbo for my 500 if not more maybe 550 @24 psi fullbuilt ls with 84mm bore
