There isn't any real power difference. People will say that the twin set up will have a vastly smaller lag time but with a good quality single turbo you will see the same. Are you going to use it for racing or for the street?

A good single setup will do just fine. Don't go too big on the turbo to keep lag time to a minimum. With that power I hope you will be using an aftermarket block.

Cool Thanks

good 4 bolt Dart block is good for 1000hp

Iron Eagle Dart block will last you forever., could probably go bigger than 331, with oversized bore out.
you can bore these Dart blocks out .125 vs. .03-.06 on stock blocks.

single turbo will be fine for you.
twins were the thing to have back in the 80's due to turbo lag.
but turbo lag is a thing of the past with newest turbo designs.

I just learned turbo mapping in school, if you can get me links to the turbo maps of the turbos you are thinking of using (single set up would be better for your application i think) then i can tell you which one would be best for you.
