Two observations: one, there’s nothing cooler than a LS1-engined BMW that is externally indistinguishable from its bread-and-butter cousins and two, the Apple iPhone is probably the worst thing for filming a movie ever. A little less of number two and a little more number one, if you please.This BMW E46 3-Series coupe, or as its UK owner has appropriately named it, the 357Ci, started its life as a 2001 325Ci with an M Sport Package. In the hands of its current owner, it received the same 5.7-liter LS1 V8 engine as the rather forlorn looking Porsche 911 we wrote about last week, making this the second American-powered German automobile we’ve featured in as many days.The engine was sourced from a fourth generation Pontiac GTO (aka the Holden Monaro) complete with a six-speed manual gearbox. The tune also included the installation of the rear suspension and LSD from an M3 as well as upgraded brakes on all four corners. Funnily enough, this doesn’t appear to be the first E46-to-LS1 conversion that’s been attempted either, as a quick search on Google will prove. There are at least three completed cars and two that are still in the shop having the conversion done. Who knew?You can check out the pictures and videos of this particular project car having its engine revved, all captured in awkward iPhoney goodness. At least the sound quality is better than the picture. Oh, and don’t forget to leave a comment below.
