i was just wondering how much hp increase i could expect from a full catback system with headers on my n/a

 

that all depends on what system you are looking at. with the racingbeat true dual set-up, it claims about a 20 hp gain. that is a complete exhaust though. you could get bigger gains through a simple street port and ecu upgrade along with the exhaust. the RTek is my favorite with simple ecu upgrades. no tuning issues to deal with and the install is simple.

 

it only claims to be 20hp? even with headers? where can i get an rtec system?

the real N/A gains with a rotary will be found in exhaust porting. i was misleading on that statement, though. the people i have known with that exhaust have gained 20 hp at the wheels, but i am not sure what RB claims on their site. the numbers are always going to be pumped up and anything above that is just ridiculous. you will already be looking at gaining 15-20% at the wheels with just an exhaust. that is a pretty major gain, all things considered. complete exhaust on an N/A piston motor might only net you 10-15 hp at the wheels, if you are lucky. rotary motors are starved on the exhaust end in order to try and meet emissions. pretty easy to get gains in the exhaust.

 

wel thanks a lot for all your info, as you can tell im still new at this but gettin better for sure if you have some good tune up info please let me know. gotta love better performance

 

that's what we are here for. what year is your car, by the way?

 

it's an 88 gxl i thought it was an 87 for a while but i checked the production date. but im thinkin about sayin screw it for now and just makin it look pretty because i dont have a whole lot of money for mods. let me know if there are any cheap mods to do really quick but im just gonna get the body finished up and put some paint on it and some interior.
