At least you guys can get translators. 86-91 RX-7's (and 84-85 GSL-SE's) have stock flapper type AFM's that you can't get rid of or swap, short of a full aftermarket EMS.

So, you're saying my roommate is going to need one of those little buggers too? That's amusing, because he runs 17-21 psi, hasn't bothered to tune his S-AFC, had his BOV adjusted to tight to actually blow off... I'm just waiting for his engine to blow up so I can have a good laugh at him. For a week.
