You don't need to get a BAM, they're not the be all and end all. They're all very similar. The only real difference is 20mm wrist pins over 19mm, but that's not the only engine to have them. AGU has a large port head so is good for going BT (mine's AGU), but they're the earlier engines which you don't get in S3s. All 1.8Ts have forged cranks and pistons, it's the rods that go.

All S3s will map the to the same regardless whether they're 210 or 225.

Possible power figures on stock internals vary greatly,but 350 is definitely pushing it.
