    74 Rx2 Intake/Exhaust Questions

    Couple Questions about Intake/Exhaust

    Will the 12a FB/SA Pacesetter fit our Rx2??

    Benefits of keeping Stock Emissions? (besides emissions... lol)

    Whats the Best Carb upgrade? (i'm liking the Weber or similar look/idea)

    Eventually i'm going to 13b 4 port. anyone with the setup currently running N/A Headers? worried about clearance issues

    I doubt that headers for a first gen rx-7 will clear the firewall and floor pan of an rx-2. The engine sits pretty low in the rx-7 so the exhaust has a straight shot under the car, whereas on the rx-2 it must go down a few inches before it can clear the firewall. I've got 2 rx-2s with first gen 12A's, and on both I had to modify RB headers to clear the floor. They should bolt up to a 74 spec engine but clearance out the back will kill you. Lmk if you have any Q's.

    Please note that if you get a pacesetter you will quite likely have to modify it just to make it work, like possibly even re-weld the header flange. They are notorious for not giving one shit about how the product actually fits on the engine or car.

    If you're going to have to modify or custom fab anyway, I'd suggest a dis-assembled header kit from Racing Beat.

    good to know, thank you. i've been using pacesetter headers on my FC for while. only thing i've found is that my FC loves to crack them lol but a lil zap zap tig and they are brand new again lol
