whats the best brand? and where's the best place to buy them for an '86 n/a?

 

nobody makes / sells real cold air intakes.

best header is racingbeat.

 

www.checkpointmotors.net

racing beat or mindtrain both sold through the rx7store.net

 

"We highly recommend installing turbo secondary injectors on certain cars"

hahahaha...


"$250"

ahahahahahahahahahahahaha....

 

Holy god thats a rip off for damn sure. 250 bucks for a damn filter and some bent tubing? my ***. For a cold air check out some of the members home made Cold Air Boxes or cold air intakes. Ill second the RB header, that **** is just tight.

 

is there a considerable amount of power increase with the exhaust header?

 

There's two types of exhaust headers that they've got for the 6port in the racing beat models, one is a streetable header, and the other is a road race header for a 6 port? how do I know if I've got 6 ports?

 

Does anyone recomend any particular intake from the RX-7 Store.net?

 

NA = 6 ports. Either make your own intake from PCV pipe (cheapy) or have an exhaust shop do it from metal. You could probably take a torch and bend a tube yourself (thats all they would do). 200$ is just plain stupid.

 

and whats a peripheral port 13B? is that the same as in an '86 N/a?

 

no that is a custom made race engine... you don't have one you have 6 ports.

 

what are they smoking???
