Cinquecento/Seicento 1.4 engine into a cinq (useful info and links)

(firstly the more help the easier)
Personally i did it the hard way, from the top without the gearbox and took the bonnet off. Then tried to get gearbox back on...
If i did it again i would leave gearbox on.
You then lift the car off the floor enough to slide the engine underneath via the use of tall axle stands.
Make sure chocks are under the rear wheels as cento handbrakes are not exactly trustworthy.
Taking the bonnet off makes life alot easier here
Using a hoist of some sort, lift the engine up into place and bolt on the OS mount.
This takes a bit of manouvering as all sorts of hoses will get in the way.
Main culprits that should be out already are the radiator, fan, water tank and charcoal cannister.
If you can now put another engine mount into position perfect. You may be able to lower the engine slightly to line up bolt holes, but would be very wary if raising. A better solution would be to raise a trolley jack underneath the gearbox casing with a piece of wood to protect and carefully lift to get it to line up. Leave the engine hoist cables in position until all 3 mounts are bolted in securely.
The car can now be lowered to the ground.
Bonnet and headlight can be replaced, chocks removed, etc.

The exhaust manifold can now be bolted on and needs to be done before the radiator goes back on as its a bit of a squeeze, prefereably with a new gasket. The supersprint manifold comes with a bracket that will secure it to the sump. The lambda can now be bolted in.
