there are part numbers on the gearbox that are visable on bellhousing, loom at them then google them, it`ll tell you what it is

2.2 fully forged motor, dubt it

ask for a reciept, again engine number is on engine casings and can be checked

take a plug socket and camera probe, although theres no garuantee its for the 2.2 crank and forged rods

someone must have built it, and there will be proof of this if its genuine
