1997 BMW M3 – How Do I Upgrade the Engine?
I own a 1997 BMW M3, which has been kept in good condition for several years. I recently got the opportunity to work in Germany. My location would allow me to perform some much-needed upgrades at significantly lower costs than I could ever wish for in the states. So my primary desire is to upgrade my engine. The US spec 3.2L M3 engine has about 240HP while the European spec engine has 321HP. Do you know anyone who has ever attempted such an upgrade and if you have any resources that might help me?
