Wouldn't take anymore to fit a K04 hybrid over a k03 hybrid. But would cost more though.
Subjective at best... K04 is a different fitment to the K03...

ive said it before and i'll say it again... if i had £1000s to spend on upgrading my 1.8tqs id much rather 1) sell her 2) buy an s3) 3) spend what money i had left on a stage 1 remap that will far out do anything a 1.8tqs can push out. harsh but true!
I BEG TO DIFFER i had 1000's to spend and i wanted to be different and have one of the fastest TQS a3's in the country. if your gonna spend 1000's then it doesnt matter which car you start with cos you will still need to upgrade the internals either way
