The thing that people need to understand here isn't the headline figures, it's the driveability. A remapped K03 was gutless over 4.5K revs IMO. The K03S isn't (mine quite happily pulls hard up to and over 6K rpm). Forget the numbers, it's the extended rev range where it's most noticeable.
So many people say it's not a worthwhile conversion. I totally disagree. I think it's well worth the outlay. I think it's the perfect compromise in cost v's performance. Now I know people will come back and say "yeah but you need all the other bits that go with it ie DP, FMIC etc etc" which is true but if you're remapping just a normal K03, you should at least have the FMIC anyway. And if you're into modding your cars, the chances are you're going to have the exhaust and possibly larger DP already fitted. That just leaves buying the turbo, getting it fitted and then mapped. Hardly extortionate in comparison to going BT or GTwhatever.
And the other thing that gets to me on here is people rubbishing BHP claims. Does anyone actually know what a remapped K03 car should put out BHP-wise or even a K03S car. Nobody believes the figures so how can we be sure what's what. Those guys that say they get 220BHP out of a K03 could be complete nonsense for all we know (in realistic terms). Where do you draw the line on what to believe? Until someone takes 2 identical cars, one with a K03 and one with a K03S and runs them side by side on an reliable engine dyno, it's all bollocks.
Rant over. I'll get back in my box (yes! I'm having a bad day today).
agreed
