As far as I'm aware both conversions are the same amount of work (and relatively easy on a 1.2 SPI). 1.6 will have 20 more bhp and 1.4 will have cheaper tax.

Stick the 1.6 lump in it.

Having errm followed a GSi when mine was a standard SRi I can safely say the GSi is quite a bit faster once you get close to motorway limits.

It's a no brainer...depending on condition that is.

Your fuel tank and pump will be fine

The question is 1.6 or 2.0

It's dead easy. Literally remove old engine, cut ecu plug off and remove ecu and pull wires through from engine bay, put new engine in, drop loom into position connect 5 left over wires colour for colour, connect electrics, fuel and water pipes, replace spi pump with mpi pump from mk3 astra. Hardest part is joining the exhaust but I just got a custom one made up.
