Staff member Points 407 Car 2002 Clio 172 The early 1.8T engines, and many subsequent engines have used similar turbos but I was wondering what are the differences between the K03 K03s and K04 turbo units. Are they interchangable and what power figures are they good for?

K04 can flow to provide around 250-300bhp The K04 is a larger turbo unit and came in 3 versions! K04-020 no temp gauge aperture in the housing K04-022 no temp gauge aperture in the housing K04-023 with the temperature gauge aperture When remapped you should see an easy 250bhp on the stock 1.8T and with other mods the K04 can flow to provide around 300bhp.
