so i'm installing my RB exhaust tomorrow, and i currenty have a dp, resonnator, and exhaust on there which is free flowing. there is no FCD on the car as of yet, and i'm only hitting 6.5 psi so i didn't order one.



in the event that my RB exhaust is SOOO much better than what is on there, and i end up boosting past 8.5 psi and my fuel is cut, will this hurt my engine? i'm only going to test it by trying to boost past 8.5 once, and if it does, i WILL order an FCD from rx7.com



until then, i will just lay off the boost...

 

I would play safe and just dont boost/just boost barely and order a FCD.



Not sure what a fuel cut would do but i would better be safe then sorry...

 

see what it does, its not gonna kill it to find out if it hit fuel cut. just ease into the throttle

It killed mine when it hit fuel cut





But anyways, I have an RB FCD for sale if you want it. Used it on my car for a long time and it worked flawlessly.

 

i hit fuel cut about 10 billion times in my old 87 T2.... didn't damage anything. hell i drove with no exhaust on. stock ECU probably hit like 20psi

 

Well then you all were luckier than I was.

 

that probably means your engine was about to go anyway. mine just gave out on my T2. the apex seals were worn to nothing when i tore it down..... well the ones that werent stuck

 

I hit fuel cut once and it didn't do anything. Just gotta be careful.

 

Good clean livin' is the secret to keeping a rotary on the road. No wonder everybody around here is always breaking ****!
