Years ago I bought a spare 4AGZE engine for my S/C MR2 for $525 ($450 plus $75 shipping) through one of the west coast outfits bringing the jspec engines into the states to give you a reference for price. The engine included the long block, exhaust and intake manifolds, coil packs, TB, clutch assembly, supercharger, etc… I believe there are some jspec engine imports located on the east coast.
