the cheapest thing to do would be to use another x22xe or even a x20xe.
to use the z22se would require another bellhousing as the starter motor will be in the wrong position, also you would need to convert the frontera to electronic throttle instead of the cable throttle you currently have 🙁
the bellhousing should be available from the states, the Solstice is rear wheel drive and I do know of a few rear wheel drive engine conversions over there.
