If i was to buy a K03 TFSi again, i dont think id take it to stage 2+ again either, i would however look at just adding a K04 turbo with a custom map. Its a much cheaper way of achieving 280-300hp on this engine than staying with the K03 and adding the intake, exhaust, intercooler, fuel pump etc.
....The total cost of a K03 to K04 conversion with all necessary parts and map will surely be more than adding an intake, TBE exhaust, intercooler, fuel pump (even an APR).
For a start, when converting a K03 to K04 you would need a TBE exhaust, HPFP, and probably intercooler, anyway. I think you made a mistake there, Sy.
I think the mistake is on your side Robin
Think about a stock Ed30. What differs between that and a stock K03?... its only the K04 Turbo, relocated DV and S3 injectors (thats ignoring any internal differences such as cams/pistons). The exhaust, intercooler, HPFP and intake are
IDENTICAL.
So if a stage 1 K04 TFSI is approx 280-300hp whilst still utilizing the
STOCK exhaust,
STOCK Intake,
STOCK intercooler and
STOCK high pressure fuel pump then please tell me why that cant be applied to a KO3 engine with the same KO4 turbo attached and also please tell me why you MUST Have an exhaust the moment you install a KO4?
As said before since the exhaust, fuel pump, intake and intercooler are identical on a KO4 and KO3 engine, if you were to merely bolt the following onto a KO3 TFSIengine you would effectively have a stage 1 Ed30 setup(barring any internal difference in compression/cams etc):
KO4 Turbo £700
DV relocation £50
S3 Injectors £100
So actually the total cost for 280-300hp doing the above method would be £1350 and as you say, a K03 setup in order to return approx 280hp needs about £3000 being thrown at it. And which will be the most highly stretched
YOur getting confused as to what the comparison relates to.
A stage 3 K04 Converted setup on a 2.0TFSI K03 based engine is th equivalent of a stage 2+ K04 TFSI engine.
What im talking about is making the K03 TFSI engine the same specification as a stage 1 Ed30. And we both know a stage 2+ KO3 is roughly the same output as a stage 1 K04
Also, i know someone who has this done to their vRS, so i know its possible
