It would be a downgrade, and that 2.2 is a Phase II *Drools* omfg I'de love to use that + an awd swap and race CRS-PGT next year. it has its peak torque at 3600 RPMS!! might hold up versus a 2.5 better than the peak numbers would indicate as the 2.5 has its peak torque at 4k. also the torque curve of a 2.2 is rather flat.
lucky sob!
Kevin what's the chassis you have at your Dads a wagon or seden, and can it be registered?
