ok i got a 2002 pontiac sunfire, its a 4 spead automatic... wat is this talkd about being a LN2 motor? im a total newb ill admit so im kinda confused, could some1 straightn me out?

LN-2 is just the code for the ohv 2.2 pushrod motor. The 2.2 was used before 1997 and the 2200 (your motor ) was used from 98-2002. The LN-2 was used in everything from the Jbodies, s-series trucks, mail trucks.....

You can't use a 2.2. cylinder head on a 2200 although some people beg to differ. The 2200 is better suited for boost since you don't have side feed injectors. I could go on and on but I will send you to a helpful link that goes into far greater detail than I feel like going into.
