ok since the other guy on here brought it up i decided to do some looking also. and i did the math based on my hp goal and i wanted to have ya’ll gurus take a look at what i figured up and get your opinion if i did the math right, and if you might be able to tell me roughly how it will spool i.e. rpm spooling range  
btw this would be a built LS-V with P&P, maybe cams, etc. etc

if you look a couple threads away, you will see a thread asking about how to choose a turbo. you should look into it, as i posted a link to help with this information.

in short: that turbo is not the right choice for your application. its a good choice, however, as it will still be in the +/- 70% range. i try to get them in the ~75% range, once plotted.

right thats the info i used to figure this up. that was partially what i was wondering i guess a gt42xxx would be a better choicelike you said for better efficiency.

i didnt understand how to figure the rpms and spool time though thats kinda what else i was aking here

thanks :rockon:
