Twin turbo engine upgrades?

[mnm99]

Here's the deal. This winter I'm pulling my engine to install my 2 drains. A little info first. I built a custom twin turbo system with 2 Garrett t-60s, 2 44mm wastegates and all the right stuff. It's a STOCK GM 350 290hp crate engine 4 bolt mains with around 8:1 comp. The wastegates are set at 4-5lbs with the smallest springs. I'm pulling it to install a 6 QT oil pan and a Victor Jr manifold.



My future plan is to build a new all forged engine, BUT what could I do while it's out that won't cost a lot of money. Or should I just leave it as is?

Thanks

Here's a pic of the system so far...
