Engine swap: Can anyone tell me if this is suitable

https://i.ibb.co/0hY4s7r/IMG-20190820-071052.jpg
I'm starting to put some effort into replacing the engine in the Nova.
I have the offer of this whole car at a reasonable price, engine seems ok. Its a 53 plate Astra 1.6i. The car has MOT, is quite tidy and almost a shame to strip, but I'm not a massive fan of Astra's of this vintage so who cares:)
Is the engine a straight fit? Anything I should know? I wont be the one fitting it (helping maybe). Put bluntly I'm no mechanic, I'm just sourcing the bits.
Any advice would be greatly appreciated.

Hi,
This should be a straight fit. I would not use the engine harness and the ecu, look for some c14se or c16se loom and ecu, it will be easier to adapt. You must not be a mechanic, just think logical, and you can do it.
What is the aim? This engine is for torque, not for hp.

The aim is more power than I currently have (1.2) and longer gears, more drivability.
I'm looking for an f13 close ratio box too.

this is the engine i have bought for my 1.2 I'm putting a SR carb on it and need to figure what dizzy to run..
