I have weighed the 2.4 compared to the 2.0 and like I said...difference of 10 lbs once balance shafts and assembly are removed...but more revs certainly DOES NOT mean more power, it just means that the tach needle is pointing at a different number...ask the high powered turbo 2.0s and the high powered turbo 2.4s who makes more power...guess what, the basic truth is 20% more displacement makes a difference, mod for mod, a 5.0L mustang engine is going to make more power than my 2.4L, why? simple, displacement, just because you like to rev does not mean that you can ignore the laws of physics, I love to rev too, dont get me wrong...but there is only so much air 2000ccs can flow, I personally love the 2.0L just as much as the 2.4L, but I am under no illusion that it can make as much power mod for mod, it cant, you have to mod a 2.0L more than a 2.4 to get the same power level, and as we all know, the more mods you have, the more unreliable your car becomes, best option for a decently quick neon(14 second 1/4 times) is simply to drop in a stock 2.4, with maybe a couple bolt ons, bam, quick reliable power upgrade with no worries for the next 70K miles, its not really fast, no, but it is reliable, and you never have to crack a valve cover bolt
