Well, I got a reply from snort performance, they say the stock internals on the N/A BA will be fine up to 300rwkw as long as its tuned properly. Any more than that the internal's will need upgrades. Xr6T can handle a bit more power than the N/A's but not as much as you might think. Of course necessary fuel system upgrades will be needed.

whats the compression ratio difference between the NA and the TURBO??

9.7:1 on na ba's.
10.3:1 on na bf's
8.7 on turbo motors.
