Ian, the key question is, how much do you want to spend?

then you can budget for the modifications you can afford within this total cost

let us all know :)
 
I have just bought an ibiza cupra myself, luckily mine was modded with a few things, and from what i can gather, it is running at about 220 bhp and runs nicely. I am looking at what i can do next to get more power out of it.
 
Other than a big turbo... not much!

Realistically what am i looking at spending to get about 260 bhp ?

Current mods i have are

Green cotton enclosed filter
forge front mount intercooler
revo stage 2
miltek exhaust with sports CAT and downpipe
and some uprated Pads (which get really dusty grrr)
 
I would think that you are probably over 220 then, someone else correct me.

You've got all of the main items, maybe uprated TIP would give a bit more.
