ok. i have a 2004 sxt 2.0L and i want to swap in a SRT-4 motor. i was wondering if anyone has done this on a newer neon(03+). i want to know what i have to do, what i have to fabricate, what i have to buy(besides engine and tranny) and wat problems may occur. i want to fully plan it out before i do it. i heard something about the sentry key messing it up but i'm not really sure what that is so if anyone can help me out it would be great.

thanks guys
