Is it a silver or a black top? I'm using invormation that was current when I did my conversion a few years ago.
Believe you need a new sump, you need to replace the waterpump (if silver top)with the 1800 sort.
Water rail, hoses and alternator mounting - you can possably utilise the crossflow alternator, fitting a zetec pully to it and sourcing a suitable size belt.
You'll need lightned flywheel and suitable clutch (and spiggot bearaing and CRB). Engine bolts up to the gearbox without an adaptor.
Also required; exhaust primaries, engine mountings, hotter cams? ARP rod end bolts (so it can be reved harder), your existing carbs (or injection) and suitable ECU, throttle pot and loom.
Also required is the coil pack - should come with the engine and starter motor.
Best job I've done and so different (and better) than the xflow)
