Never mind... i saw your mods on top of the page.
i have an 88 too with cone filter, leaky pacesetter header and stock exhaust and the car ran 16.6.....(

).. full interior.. and a fugged up almost bare to the bone clutch.
there are a lot of quick 86-89 rx7 around here.. they're not really saying anything.. wait till you run this guy in black rex around pinellas park. i think he goes by the name of RJ..... i might be wrong.. his car is the shit.
