....Be fair, Dom - Compare new prices with new prices.
What about injectors needed for K04 on a K03 car.
Even back in 2009(?) when I replaced my K03 (with a newer K03) the K04 conversion cost was ~£3,500.
There's more to it than just spannering on a bigger turbo.... Unless you want problems further down the road.

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 :booty:
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
:innocent:
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 :P

Thanks, Sy - That explains it all very well :drinking:
I guess that my thinking that it would be very limiting having a remap without also a TBE exhaust led to my conclusions. Surely you need a remap when you go from K03 to K04?
I remember all the debate about the internal/strength differences between the Ed30 and the Mk5 GTI when the Ed30 became available. To this day, I'm not sure that anyone really knows for certain everything that VW did. Being somewhat cautious about the extent to which I modify my K03 GTI, I step back from either Stage 2+ software or a K04 conversion.
GrayMK5GTI:
Standard injectors (K03 engine) can flow 300bhp so all you really need for 300bhp is:
- k04 turbo
- discharge pipe
- DV relocation
- downpipe & Sports Cat (for a JKM 300bhp)
- custom remap
