im gettin a 90 civic hatchback rehauled with a new engine and exhaust system since one of the cylinders gave. i have about 3000 to spend and i cant do it myself. i would like something with bit more performance than the standard factory. On the exhaust, i would like something not crazy sounding but something that has a deep clean tone but nothin too loud and obnoxious. i would like to get racing suspension but i got no idea how much its gonna cost. the car is also a 4spd which is a bit awkward........is it worth changin to a 5spd even if the transmission is relatively new (6 months) Any tips and/or suggestions would be mostly appreciated thanks!!!
