i just bought a new hybrid turbo unit from AET, i want to upgrade the fuel injectors. the turbo is rated at 280bhp, should i get the 440cc?? also do i need to change the fuel pump and n75 valve to get the most out of my new unit? Also to be mentioned is that the new turbo gets a big thumbs up from me, even with just a sports cat and air intake the difference from the stock turbo is unbelievable, alot more whistly 2!!

I'd go for the extra bits off of the S3/Cupra that people get if doing the K04 turbo conversion:

Although I guess if the AET turbo is a K03s hybrid rather than a K04 you will be using the existing manifold, downpipe and oil lines with no problems.

I would change the injectors to S3/Cupra R ones. They will be fine for your bhp.

Not sure on fuel pump tho.

thanks guys, the turbo is classed as a k03/k04 hybrid. All manifold etc are standard.

does anyone know what size injectors come out of the s3/lcr??

has anyone here tried using this FMIC??

I think this intercooler seems resonable. £400.
