Thanks much Jason. I'll check the link out. The weight figure is a bit of a bummer. The current M Roadster checks in a 3197lb. But, it 35i engine has big horses. Still, the current M Roadster also has big horses. I am going to check out the gearing.

Edit: Here are my results of checking.

6-Speed Gear Ratios: i35 vs 2008 M-Roadster

1st 4.055 4.35
2nd 2.396 2.50
3rd 1.582 1.67
4th 1.143 1.23
5th .0867 1.00
6th .681 .85
Diff 3.64 3.62

HP: i35 vs 2008 M-Roadster
300/5800 330/7900

TQ : i35 vs 2008 M-Roadster
300/1400 262/4900

Interesting contrast. I’d have to know more about the torque curves, but given the weight advantage of the M Roadster, it looks to me like the M will come out on top.
