Bottom end is designed pretty strong from what I've seen... The trans would be my #1 worry, and MAY be why Mazda limited the power a bit in our cars instead of tuning it to the max potential. :/I feel like if you could lock the intake cam to fully advanced you could probably get relatively aggressive with boost. Bottom end components would probably be the only point of weakness, but as of yet that's only speculation. We'll see what comes out as far as bolt ons. Power seems to be my only point of contention with what is already an amazing car and from what I hear from other I think were all on the same page.
