Hey guys I gotta 85GS-mint condition.Cats were clogged- I bought a midpipe w/hi flow cat from a friend that said it increased performance on his 7-it goes from stock to 2.5' back to stock...then to hi flow cat and stock exhaust-I am planning on strait pipe now since I'm in MO instead of CA but...the problem is I pick up well until 5-7k where most rotarys love to be.I can scratch 2nd and 3rd at about 7k no problem,but it just doesnt have the power of my old gsl or sa22c. It goes ok until 100 mph but it wont go any faster unless I'm going downhill-the fastest its been up to on a good day is 110-definetly the slowest rx7 I've ever owned...I have trouble beating a stock crx on a freeway!!I'm not used to that whatsoever and enjoy shuttin honda's down every chance I get-
I want to get a new carb/intake setup along w/ a header and new midpipe to strait pipes-I'm sure this will make my car faster,but,for now,whats the problem with my car? HELP PLEASE

Check the timing on the ignition. If someone got the leading and trailing mixed up, it can do what you describe. Also put some new spark plugs, new spark plug wires, cap and rotor button on it, and a new air filter.

You definitely need to get your exhaust system free flowing.

If you do all that and it still runs out of top end power, then check the fuel supply system; maybe the carb is running out of gas after a few seconds of WOT. Tee a gauge into the fuel line right next to the carb where you can read it while driving and make sure it has at least 3 psi when running WOT in 3rd and 4th gear.
