Building a Brand New M62
This build involves a rare 2003 X5 4.6is that belongs to Dan that was daily driven. The X5 was bought in California and shipped from California to Raleigh, NC. From there Dan had the original faded Estoril Blue removed and had the entire X5 resprayed in Atlantic Blue. Dan not only used his X5 for daily driver duty but also to trailer our beloved E30 shop car to and from events. After a few trips the X5 4.6is drivetrain was showing wear. Dan removed the X5 from daily driving/ tow rig duty and began the process of removing the original M62 from the chassis for a refresh.
The M62 has seen a few updates since it was first introduced in 1995. Being the successor to the M60 the M62 features Alusil cylinder liners and a single row timing chain. In 1998 the M62 received a technical update which added variable valve timing, electronic throttle control and a DME software update this gave it a new name M62TU. The M62 we built as a brand new engine is a M62B46 which was co developed by Alpina. This meant the M62 was bored and stroked to a 4.6 liter V8 increasing power output.
We purchased a brand new M62 block from BMW, new connecting rods and new pistons. We had the cylinder heads reconditioned with all new parts including high performance camshafts and had the crankshaft inspected for any issues. Other new parts included new sensors, valve covers, seals, gaskets and a new cat back custom exhaust. This will truly be a brand new M62B46 for Dans X5 4.6is and prove to be more than capable of returning to daily driver and tow rig duty.
