So the 1.6 16v engine will be a more straight forward conversion?

Im struggling to understand which drive shafts i need for the XE.

Drivetrain

As the engine is a big block engine you have the choice of a few gearboxes. The most popular are the F16 and F20. Both will fit straight onto the Corsa using the Corsa gearbox engine mounts. You use the Corsa gearlinkage not the gearlinkage from the donor car. You can also use an F28 gearbox if you want some six speed action. You will need to modify that gearbox to 2wd and use custom gearbox mounts, M-Tec produce an F28 conversion kit. I will post more information on this when I know what you need to do!
Driveshafts are another issue. I would recomend you use Corsa specific 2.0 driveshafts because they are the correct length, but there are other options. You can use Mk II Cavalier 1.8 inner CV's which fit onto Corsa driveshafts, you then need to use Corsa outer CV's. This setup will more than likely break due to excessive torque being put through the driveshafts and CV's. You can of course use Cavalier/Calibra equal length driveshafts or 2.0 Astra driveshafts. If you are using Vauxhall big block driveshafts and outer CV's or Corsa 2.0 sepcific driveshafts yo uwill need the correct hubs to mount the big CV's to. You can either use machined Vauxhall hubs from the donor car so they fit to the Corsa bearings, specific Corsa 2.0 hubs (which are the same as machined hubs) or a Harry Hockley set up. The Harry Hockley set up uses bigger bearings which fit into machined bearing knuckles so you do not have to machine (weaken) the hubs to fit.

The passenger side (short) driveshaft is the driveshaft that is too long to use in a Corsa. You can buy these from M-Tec on thier own, and use a Vauxhall drives side shaft...

Some use Corsa ones though but they have snapped on a lot of people.

It seems very hard till you're bawdeep in it

If you need some shafts i'm sure folks on here could sell you them, it's pretty easy and before you buy make sure you're 100% sure, everyone will help you out!

Go for the xe

Not one single difference, it just links onto the throttle body, which i'd clean up etc while the engine is out anyway

1.6 fuel pump is fine, basically if it fits, it works. Clutch well i'd replace it, but if you get engine and box together often clutch comes with it, it's upto you how much you want to spend, what you see as important on the list.
