lets take weight then, a typical 98 neon and a typical 67 mustang, guess what? they both weigh the EXACT SAME, even though the 67 mustang has a 4.?(289ci, something like 4.8L) liter engine and is rear wheel drive to boot, now lets turbo charge them both at roughly 10psi(both having stock internals) the neon jumps to 240-250HP or so, the mustang jumps up to 320-330HP...what was that about weight? also the mustangs rods dont decided to snap at 270 ft/lb of torque(as I said about all other things being equal, weight included)
