.....You're still not understanding. A GUTTED (i.e. stripped out interior and other weight reduction) 240 with a NON TURBO'ED KA24 weighed in at 2500lbs. The car with the LS1 is full weight to my understanding and weighs 2700lbs. The 2500lb car is gutted AND has the non turbo version....therefore we can't really compare those two weights. The OP was making it clear that when he mentioned the 2500lb car is was a gutted car with a non turbo ka24....so it really can't be compared to his buddy's car since he didn't post a previous weight when he had the ka24 setup. So yes.....the guy's LS1 240 weighs 200lbs more than the other car. But....it has heavier wheels, has no weight reduction, has a beefier rear end, and the other car is a non turbo car (have to factor weight of manifold v. header, turbo, piping, intercooler, oil lines, etc.). So no....it's not a fair comparison. Which is why I'm still believing an LS1 240 will weigh slightly less than a comparable 240 with a KA24-T.
