Default twin T04E sizing question

On a stock cubed ls1 what size turbos do you guys use in a twin setup? I have a T04E .60 a/r 50-57 trim compressor side (cant remember exactly, Ill have to measure the wheel) and a .58 a/r p-trim that is left over from a previous car, if I got another one this size would that be a good size for a twin setup? Or do ls1's tend to prefer larger exhaust housings? The goal is somewhere in the neighborhood of 800hp at the crank with as fast spool up as I can get. Im interested to see what you guys think!

Thanks, Rob

You'd be stretching it making 800. But that's not to bad, my CAS uses 76mm T04E's. There custom to fit that big a wheel. You'd be about right with those turbo's and that cubic inch.

That is the exact size turbo I have for my V6 Truck. Im not sure exactly what the "best" turbos would be, but from what Ive read, it seems like T61's are a very popular choice.

Best of luck bro,

Garrett
