Upgrades what to do next!!!!
 

I have a 97 civix Lx 5 speed. So far I have put a Tenzo short throw shifter, AEM altanaror and power steering pulleys, DC 4 to 1 headers, Greddy evo-flow cat back system, and a generic highflow cataylitic convertor and AEM highflow cold intake.(i also had to custum wire the 2nd O2 sensor cause the orignal wire was to short). Before i go to turbo or NOS what should I do next.

altanaror :D
DC 4-1 *header* you mean....4-1 on a D16Y7? eh...

swap the motor....thats what you should do next. or a cam gear or a camshaft or throw on a Skunk2 IM or the EX manifold. but all the modding of that car wont make it fast unless you are willing to throw down A TON of money, and i mean a ton.
