Hi,

the oem intercooler should be fine for your application, possible a TTE group a spec intercooler is a option for you

to raise the performance of the water to air system go for a higher water amount, i drive 1:1,5 (anti freaze:water)
this is what i did first until i would spent money

if a minimum lag is your target you should stay with the top mounted intercooler and in front of that you are from cyprus i would guess
that outside temps are pretty high, so consider a water injection (a good adjusted system is able to reduce engine lag)
