Hi Don. FYI the WBX goed 265 lbs with engine cradle etc attached, the 2.2 Subaru motor 290. I think your I-4 with its cast iron block will weigh more than either one. But you should definitely supercharge your motor, that's got to be a good thing! 8-) On 5/18/07, Don Hanson <dhanson@gorge.net> wrote: > > Hi Jim > No, not the boxer motor.
