is it a good or bad thing to take off the cat i got mine off and i havent noticed any problems yet but i really cant say i have noticed a increese in power either?
anyone got any input??

 

huh? did you replace the cat w/ something else or just... leave it off? and if you put a midpipe on and your running stock twins you should expect boost creep...

Put your main cat back on. If you don't know the effects of removing/changing something, DON'T DO IT! You need to spend some time researching this car. Any changes to the airflow must be done carefully with an FD. Besides, if you removed your main cat and didn't notice a significant power change, there is already something wrong with your car.

Please spend time learning about your car before you blow your engine, and become another person who goes around saying "what a POS RX-7s are".

 

agreed.

 

whats boost creep? and ya i got a mid pipe
i thought the cat just made the car not breeth well

 

Thats why Rynberg said to do some research. You would soon find out what boost creep is and what you need to do to SAFELY mod your FD. These cars are not as bulletproof as a supra or something like that where you can put an intake and exhaust on and crank the boost and not have to worry about it. There are sone careful steps that need to be taken.

 

thats y i am here to learn no1 has told me that it would hurt anything yet? see i was into camaros before and it goes with out saying that these 2 are compleat diferent cars, i dont know where to look for some research is there a place on the net? as you can see i do want to know haha and tell me what boost creep is so i know 1 more thing

 

Boost creep is when the stock wastegate can't hang with the increased air flow caused by modified exhaust/intake, so you get slowly increasing psi at WOT. More power, but the problem is that the stock ECU doesn't know the difference between 10 psi and 11-12 that you get when you creep, so it supplies the same amount of gas for both.. you creep too high and dont' have enough gas being supplied to your rotary and bam, it'll detonate and you'll need to rebuild.

 

ok so how do i make it get more gas?
man im glad i came on here becouse ive been doing things to my car that isnt very good the outher day i got ahould of a buddys boost controller and cranked my boost up to probley around 14psi or more
i took it off but i didnt know this car was so picky i may end up selling it in that case

 

It'll be fine as long as you're careful. Do a search for "reliability mods" and do those first. You need an aftermarket ECU or a reprogrammed stock that'll be able to keep up with the boost.

A few mods and you shouldn't have to worry. Trust me, it'd be worth it, I doubt you'll find a car as much fun to drive.

 

i think thats what ill do

thanks buddy
