2.7L engine
 

Are the 2.5 and 2.7 litre 944NA engines different externally?would you be able to tell one from the other just by looking at it?

same bore, longer stroke... I'm guessing that the 2 engines appear identical... but i really don't know

Yes they are visually different, look at the valve cover, the plug wires are rescessed into the cover itself. Also the instake has a more "turbo type" look to it.

isnt that the "S" your talking about scott? the 2.7's looked like the other engines and were only available in 1989

weren't they bored? I thought that the stroker crank would bring displacement to 2.8?

944, 944S, 951 all have the same bore and stroke, '89 944's have the same bore, but use the longer stroke crank from the S2, the 944S2 has a bigger bore and same stroke as the '89 944... best of both worlds... 968 is the same as the S2, but adds variable valve timing.

Take another look Bob

yup, i got it backwards, they all have the same stroke and bore (who the hell lists it like that?? i always have seen bore THEN stroke #s), '89 were same crank and fatter bore, S2 are the only ones with the longer stroke crank, same bore as the '89s... still best of both worlds

so they are exactly the same cept for the little numbers under the manifold?
