All,

I was thinking of fitting a 325 bottom onto my 320 engine as my friend has blow his head so this part of the engine is spare.

Will this make a difference? Also if I change the throttle body from a 325 and onto my 320 will this improve anything?

Thanks

It won't work - your valves will hit the pistons. And it's pointless anyway, since the 320i head would strangle the cylinders and lose you a significant amount of power.

thanks for the reply:)

swap the whole lump, if its a late 320i much of the electrics is the same
