You can directly put in a 4AGZE supercharger (M) engine in my Corona AT 150 JPM. But you have to use back your ori dashboard b'cos the Levin dashbd is narrower (got gap). you can use the supercharger meter.
Any of you EVO owners have a spare set of the ignition coil packs? I think mine are gone; changed plugs, changed cables and still missing under boost so I guess the only thing left to change are the coil packs.
