The only A6 block that is stronger thanthe Z6 is the one with the iron main bearing caps. The later A6 blocks went to the full aluminum main bearings caps/girdle, where as the earlier ones (stronger ones) had iron main bearings caps with an aluminum girdle that bolted to it. The iron bearing caps are more stiff/stronger, and keep the crank more stable under bigger loads (boosting/high rpm).
I guess I will have to put the si hatch motor on hold and just drop the oil pan and take a look see.... might stick the vitara will work in my stock motor if its strongest... hummmm
either way Scrappy will end uptop with turbo and vtec......
whoops did i let the cat out of the bag
