petone 0 Report post Posted November 17, 2005 you neeed to put the 2.5 loom and ecu into your car as the 2.5 will be motronic and your car is L-jet, so some re-wiring is required. Are both g/boxes manual? If there are they should all bolt up fine, even use your old slave cylinder. You will need to shorten your driveshaft as my friend did the same swap, (if your 320i is manual that is). LSD will go straight in. I have a shortened d/shaft for sale which is for a 325i engine and 5spd box. Quote Share this post Link to post Share on other sites

petone 0 Report post Posted November 17, 2005 ahh even better, so you will have the whole car there when you do the swap? In that case just take everything from the 325i. Also take its swaybars, front struts (if they aren't damaged) cos chances are they are bigger and beefier than your 320 stuff. Quote Share this post Link to post Share on other sites
