O.K. the 4th Gen weight's 2,800 not 2,900 buddie and the RSX weight's 2,700 so there pretty much the same...also account that the RSX has a 2.0 Liter which i'm sure weight's a lot less (newer and probally has things that weight less) then the Prelude's older 2.2 Liter engine in account I knew the stupid RSX body wise weight's more then a Prelude I just knew it

(don't mind me I'm just being stupid)point is...if you got the money y not swap a k20??? tho If i'm U and I want REAL POWER and money isn't a ISSUE then y not SWAP a JDM h22 TYPE S?? 220 HP for sure and i belive but could be wrong 165 Torque...
