what mods should i buy?

[ohadohad2]

i about to get my 02 Ibiza 1.8 turbo

and i was wondering what parts should i buy and where i can get them the cheapest

becuse of the warrenty im looking for BPU level only
i want:

BOV

exshust - i prefer a quite one i like the sleeper look

preformence chip - although i think it will be better doing it custom made after installing all the parts right?

air filter

turbo timer - i was thinking about HKS black US spec (or whatever it name is) cuse i dont want to sit in the car like an idiot waiting for the turbo to cool off

maybe upgraded spark plugs

and maybe an apexi - this is where i really need advice

thanks
