Alright... I was wondering... what do you guys think would be better.... Twin turbo, or ball bearing single turbo.

Thanks

big ol' single will have a higher peak horsepower, but take longer to spool.
twins can be set up to spool almost immediately. and have a smoother torque curve.

The part about singles having higher peak hp only holds true for factory twin turbo setups like the sequential system on the FD. If you look at the quickest rotary drag cars they're all running twin or even tripple turbo setups on 20B's.

In theory, a twin system allows you to use smaller turbos which increases low end response while still having the same power potential as a big single. That being said, there's not much point in doing it at least for a 13B. When you compare the extra weight, complication and cost involved to the slight increase in performance it's not really worth it. Unless it's a 20B or RB26.

I think it also depends on whether or not you are going to run a 12A or 13B and what type of port you have. The air flow is important in determining turbo size in my opinion.
