M10 head differences...

[Cracker Red]

My head is cracked.

Nearby, there is a 2.0l M10 out of a 2002 that I can buy for less than 100. Can I use this head with my dizzy/injection on the 84 318i, or is it all different?

I hear the combustion chamber is a bit larger, but the valves are smaller on the older head...but same bore. I'm unsure about clearing the pistons though (quite a dome on these 318i pistons)

Thanks!

As far as I know the injector ports (or lack of them) may be an issue.

im pretty sure the injection will work
you have to check the gears on the dizzy...some spin cw and others ccw

02 heads use 2 row timing chains
and e30 heads have single row
i think i have heard of guys changing them out

02 pistons come in two types ...bathtub and piano top type
piano heads go w the e12 head
and bath tub go with the 121 head
(double check that i got that right)

pistons from e30s have a all together differant shape
im not sure which head they would or if they would work w an 02 head

try 2002bmwfaq.com
im sure its in the stickys there
