interchangable parts 316i and 318i??

[charlie316]

Any ideas?

What parts are interchangable between 316i and 318i or even 320i to gain power on a 316i touring?

as you can see from the response we are all scratching our heads other than fit the 320 engine to your 316 thats about it or tie some fireworks to the bumper

What about changing the throttle body? would a 318i fit onto the 316i engine?

The only obvious answer is the whole 1.8 engine. +200cc has to be an improvement on 1600cc.
