hello everyone

i have been looking around for the m103 3.0 12v with not much luck.

turns out they not as common as i thought.

ok so i have a 2.0 8v m102 at the moment.

is this as strong as the m103 but only a 4 cylinder? or just wishful thinking.

further, what is the difference in head design of the m102 2.3 8v?

would i have a problem with valve clearance if i put that head on my 2.0 block? if so, would i be able to mill the block a little bit to fit the head. and would milling the block have catastrophic side effects? ie blown head gaskets and stuff?

thing is, i get fantastic economy from my 2.0l. and changing the whole motor to a 2.3 for 10kw doesnt seem worth it. i know i cant keep the same economy if i want power but im still trying to find a trade off between the two.

i have heard that the larger head will lower compression and so will milling the block. wouldnt this be good for a turbo setup? or will it just weaken the block near the head?

i know that lower compression will result in slower acceleration off the line. im ok with that coz i could save fuel in the low revs and get nice strong boost response when the turbo spools up.

also, can i use the 230e fuel distributor with the new head?
