389l

hello a am building a 6 liter chevy . I was going to use two gt3558rs but after looking at the comp maps i think two gtx 3076rs would be a better fit. engine specs are 6 liter ls , forged bottom end, cnc ls-3 heads, 6500 rpm max looking to make 800-900 hp . What do you guys think? OH ya .82 ar exaust.:

i like the gtx series cause they got smart and copied Borg Warner extended tip design thats why the gtx comp maps look that much better im personally more bias toward BW or Holset turbos myself but i recommend the gtx3076 cause that just that much better design than the gt35
