Wild Idea

834 Views 6 Replies 7 Participants Last post by  dave
I just had a pretty wild idea... I wonder if any of the German tuners like ACS or Hamann has done a E46 conversion and dropped in an M5 engine. I remember seeing Hamann having a V12 in the old E36, so I think it should be possible to fit an V8 into the E46.
The weight of the aluminum V8 should not be that much heavier than iron block I6.
Anyone care to comment on the feasibility of the end-product? I personally think that the car would have the nimble handling characteristics of the E46 while having the power and smoothness of the M5 engine.

Comment #1: I've seen various 'official' numbers floating around, some numbers say 0-60 in 4.8sec and some say 0-100kph in 5.3sec, it certainly does not take half a second to get the extra 2mph, so one tends to think different pieces of the organization are pitching different numbers for differing reasons.

Comment #2: I'm not sure what the difference in wheel weight is between the OEMs and the Schnitzers, I can't imagine the OEM wheels being crappy-Neeper-aftermarket heavy.

But yes, reducing the rotating mass can result in considerably more torque getting to the road, I've seen dyno tests where a 15lb reduction in wheel/tire weight resulted in a 20HP increase in dyno-measured HP.
