i have an 86 non-turbo 13b and i just recently gutted my cats and took off the hose that comes from the engine to the last cat. i has smoked before i did the gutting but at least now i can get the car up to 6500 rpm's where as before i could only get up to 4000rpm's any way the car smokes like crazy white smoke when i get on it any suggestions????

If it's a really white smoke, you probably have a failed coolant seal. If it's kinda bluish, that indicates burning oil which is probably a bad rotor oil seal. Either way, high RPM smoking most likely means it's time for a rebuild.

 

who does rebuilds and should i just get a new engine. oh and off the topic what does this FC thing mean i am new to the rotary engine concept.

 

Demonrx-7 check your pm's.

 

FC = 2nd Gen Rx7 86-91, which is what you have. It comes from the code in the VIN #ie: jm1fc...

If you have a bad oil seal, I shake your hand and welcome you to the club...

 

did you wire your 5th and 6th ports open?

 

i dont know anything about the 5th and 6th ports.

 

I think you should read the FAQs.
Lots of good info there.

 

Agreed. The FAQs have a lot of info. Also, you should be able to answer most questions with a good search. There are a lot of knowledgable people here, and most topics have been covered at least once.

 

if you do some searches you will find out that hose you disconnected from the main cat opens them.

 

THAT SUCKS HOW DOES THAT WORK IT LOOKED LIKE AN INSERT TO THE CAT AND USUALLY THAT IS JUST AN EXAUST RUN-OFF HOW DOES THESE PORTS WORK???

 

why are you yelling? :P


the 6 port system is kind of like VTEC on hondas, without it you have NO high rpm power at all. That wire needs to be plumbed in to the exhaust system, and without your cats you may not have enough exhaust backpressure to open them.

you canjust plug that line and wire them open, but it costs you low-end torque.

 

OH I AM NOT YELLING I HAVE TO RUN A PROGRAM AT WORK THAT REQUIRES CAPS LOCK TO BE ON SO I DONT TAKE IT OFF. SO IF I JUST PLUG THAT LINE THEN I WILL BE FINE CAUSE I SCREWED UP THAT LINE AND YEAH I DONT HAVE ENOUGH BACK PRESSURE ANYWAY. BUT YOU ARE RIGHT ABOUT HI END POWER I CANT GET MY FC TO PASS 108MPH AND THAT PISSES ME OFF.
