Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

Hi, Im new to this so if i get anything wrong please let me know lol
im 17, soon to be 18.. and i have my little corsa 1.2 which is fine, if your an elderly person haha. My mate has a 2.0 8v engine (115bhp) out of a cav with 80,000 miles on the clock.
so the plan is.. buy that engine (which is missing the gearbox and half a loom) for £90 bargain.
The car itself has been lowered 60mm all round on jamex springs/ shocks which are quite solid.
it has 15" astra alloys, 3.5" stainless backbox, k&n, sport interior, sparco steering wheel. usual stuff..
I also have a set of 1.6 16v corsa disks&calipers

so my questions are:
Will the suspention be ok with a 2.0 in it?
will the 1.6 breaks be good enough? (maybe drilled& grooved disks?)
What Gearbox driveshafts will i need.. ive had a look, but it all looks a bit complicated.
Can i keep the standard hubs?
what Fuelpump would i need?
What radiator would i need?
plus anything else i would need?

Im on a tight budget, not earning mega money so this might take a while, but im sick of cocky bmws and audis.. something needs to be done haha.

any help will be much appreciated, thanks.
