all i want is a car that goes fast when i want but will still be a nice car to drive normally.....although i was thinkin about supercharging....hehehe! but that a whole other kettle of fish

Some of us want them for rally car use, as we now can use these blocks instead of the a12, saves time and money this way.

so the rules say A14 are ok.. not A15?

so which one is better with turbo/supercharger the a15 or a14, because in the L series the L18 was better suited for turbo or super

a15 has decomped head
mix n match bits for lo comp turbo motor
all else being equal bigger is better

so the a15 is the way to go, the l series isnt like that as they all share the same type head with a few small differences

yeah, the powers above gave us all a 17% engine capacity increase using family motors, so the a14 is the real way to go, however, from there you can go as far as you really want, 79mm pistons might just have to be ordered!!

you can do that with an a10!

l series had about 4 or 5 heads v91 comes in lo comp and hi comp they are left over nissan racing heads as are the u60 conrods
dazza

the best part about the heads is that they all fit every motor from L16 to the L20b, i use the U67 head
