Was wondering which are possible and which are not. For those of us thinking of upgrading FROM E36 TO E46, if it's possible most of us want to bring up most of the mods that we have done right? So, lets start. Rules of the listing is simple. Swappable=Yes means direct fit from E36 to E46. Else state if its direct or require minor mods (RM500). Should you need to state car model (e.g. 325i etc), do so. Engine1. Engine - ?2. Throttle body - ?3. Air intake manifold - ?4. Exhaust headers - ?5. Cams - ?6. Pulleys - ?7. VANOS - ? Chasis and wheels1. Shock absorbers front2. Shock absorbers rear3. Springs4. Brake hoses5. Brake callipers front6. Brake callipers rear7. Rims8.9. Body and exterior1. Kidney grills2. Body panels3. Interior and cockpit1. Diagnostic unit2. Steering3. Hope you can share your knowledge for our common info. BTW, we could also do the threads for E46 to E90 etc.
