Max Power from twin turbos

[97SupraTT]

Hello all,

I just recently purchased a 97 twin turbo supra. The car is almost stock, the way i wanted it so i can do my own work. I have wanted a supra since i wanted to drive and finally got one.

Now i need to start my project. Not that it doesn't already have a lot of power but i would like to get more power out of it. I'm not looking at drag racing it right now or anything so i would like to keep it running on the twins right now. My question is: How much power could i get on the stock twin turbos and what would i need to do to achieve that power? I'm looking at around 600 crank horse power at least. Please let me know what you think. Thank you.
