ok i'm just about to wrap up with my build k24/k20
4 piston 156 Head
full ferrea val train
skunk 2 ultra manifold
stock bottom end
and a **** load of other parts ....


ive been hearing lots of mixed review about the m5 gas but i see guy run great number and make good power but then most of those car blow up and the owner say it was the gas melted the piston.... then i know people that used the ftw red and made awesome power but no where near the m5 results now . My question is the following have you used any of these gas on a All motor set up and whats your feed back .. just looking for some different opinions from what i been getting out here in NJ ....... again only feed back from those that have used either or gas on a all motor car .. thanks
