Hello and welcome to the site mate
yes you can mate. you will require however the following
bigger intake
bigger maf
different turbo
exhaust manifold
downpipe
injectors
and mapping just of the top of my head
the engine in yours is the same as mine so should be an AUQ engine, blocks safe limit is around 300bhp
current turbo is a K03s which as it stands just now starts to have problems around 240bhp, you could have it hybridised which would see you at 260 and save you the hassle of exhaust manifold and downpipe but you would need a sports cat and everythng else on the list.
for the trouble and cost involved you would be better off with the Cupra R 225 and a £300 remap to see around 270.
