Default Turbo sizing for 402?

If given the choice between twin T3/T04B stage 3 with .82 AR turbos or GT30R's with .82 AR which would you choose? Keep in mind that price is an issue. The GT's are about $1200 more. Looking for up to 800rwhp with forged 402. I know the GT's should work well but would the T04B's?

30's

even big 04B's will be small for that motor, not to mention t3 hot sides.

If price is a big concern go with twin MP-60's on a T4 chassis and .68 A/R's.

T4 will not fit my setup. The two I mentioned above are the two I can choose from.

Has anyone used the T3/T04Bs on a larger cubed motor? How did they work out?

How do you think the dyno graph would differ for the two?

Thanks,

Chad

Max boost is about 14-15 psi. But probably driven on the street with 8-10 psi.

I knew you were going to say that.
Got to find some way to stretch the budget I guess.

Eh, it will be worth it in the end.
