congratulations on you new car! i dont think they make 4 door sr20's ( the 2.0 engine ) so you got a 1.6 you can always look at the sticker when you open the door. 1597cc means you have a 1.6 or if you see the engine code GA16DEhi, my names cody and i just bought a 94 sentra limited edition. i think its a 1.6 but im not completely sure. its a 4 door, twin cam. is there any way i can tell for sure what engine i have?
