Quite straight forward you will need;
Engine (complete), gearbox with shift linkage, exhaust, rad, oil cooler, ECU, & prop.
This lot will get you going you can then also upgrade the brakes, diff, ARB's & suspension to 325i spec.
As luck would have it I have all the above available if you are interested

Already done, apart from the diff, if the 318 happens to be a cab or a touring.tomson wrote:then also upgrade the brakes, diff, ARB's & suspension to 325i spec.
You will need to add mounts for the coolant resevoir bottle, and modify/change the mounting bracket for the air filter.

True but the front springs will still need changing to 6cyl items....Brianmoooore wrote:Already done, apart from the diff, if the 318 happens to be a cab or a touring.tomson wrote:then also upgrade the brakes, diff, ARB's & suspension to 325i spec.

Easiest thing for you to do would be to buy a complete 325i to strip for the bits you need.....konflik1 wrote:thanks so far.i am in barbados and looking to do the swap soom just gathering parts.
Do you have a saloon or cab? You wont have a Touring unless it's been imported.
