[QUOTE="atafonso, post: 596278, member: 23592"] Hi Stefan The fact you will have a bigger displacement does not necessarily mean you will generate more heat at all times. With way more torque you will not have to put the engine under a heavy load to move the Bus. What makes the heat is the amount of load you will subject the engine. Lower load, lower temps overall. The alu case runs hotter on the type 1 as the magnesium has a better heat dissipation property than the alloy used on the alu case plus the walls of the mag case are thinner. I know that by experience, not by what others say. I said they run hotter, not that they are not stronger. They are stronger but not needed IMHO for engines that makes less than 250bhp. CB Performance at one point was using the alu in their performance builds but they have switched back to mag in most combos. Only on the very high performance all out engines they use the alu. It's also heavier, has loads of cast fleshing that i myself, clean and deburr all when i build one. Also the oil holes to the main bearings are not aligned, requiring some mods. Not for your average builder. Abel [/QUOTE]
