Mugen Si performance specs are the same as the other civics. The only thing that the Mugen has that is different from the other civics are the body parts...
197hp, 139 tq
wut a waste of almost $30,000
Rather go with the new 08 Honda Accord, v6 has 286hp, 248tq.
And the new coupe looks soooo much better than the Mugen
