The old engine from the XX has to come out, along with the attached W57 5-speed box.
Engine is only the single-cam 1G version with ~95kW according to the specs I've found. Goes well, the engine is in the car so you can here it running.
The gearbox feels fine, driven the car no problems, nice to use, nice and tight.
Would prefer a Perth buyer but if someone REALLY wants the W57 we may be able to arrange something.
Make an offer, because I'm lousy at making up prices.
