I'm not sure, but I did see an RX3 with a n/a cosmo or what it seems at the rx7 dyno back in the summer.

was it a BP? ive only seen one thus far (or it could just be the cosmo intake setup on a normal NA 13B?), i was wondering what it takes to run one thats been BP'd? and what sort of output i could expect.

FYI,

While the Cosmo RE Intake is absolutely beautiful (my favorite BTW), it is designed for forced induction.

It is NOT a great design for normally aspirated setups, and can
be very restrictive, when the air is not being FORCED via BOOST.

f you have the means, run a better intake, or at least modify a larger throttlebody setup for it.
