But when it is time to sell, put it all back together. Is it really worth it?

Are the non-aftercooled engines any more "fortified" against heat than a aftercooled one(6BT vs 6BTA). Or is the turbo bigger on the aftercooled ones and/or do the generate more boost causing more heat? I guess the real question is right up to the aftercooler and is everything the same after the aftercooler?....the only difference being a cooler air charge and hence more power....
