I had a factory 430 kit on my car when stock, I really liked it ..... I would assume going by the road tests, etc that the big 'hit' will be a little more delayed with the 450 kit though more intense when the turbos get going. Depends what you want really.
Btw, saw your car in W1 over the weekend, looked lovely

I have the factory K24's with FVD ECU program and .5 bar fuel regulator. Huge difference over stock and the car is much more fun to drive, especially if you mash that right pedal! I am very happy with the mod with minimal extra lag. I've heard that ECU programming is a key element for reliable power / reduced lag issues in this conversion. FVD quotes 490hp. Who knows? It feels A LOT stronger than stock. I estimate I spent about $5K for the whole conversion. (done by a Porsche dealer).

I have the K24's and have de catted. IMO, no lag with this setup. Power delivery about on par with the K16s till you hit about 4000 rpm (with foot on the floor . Then major difference! The acceleration will take your breath away. Because there's so much more available above 4000 it could feel down on power below that, but the torque/power curves decry that. The power comes on as a built up surge though so it won't catch you out. You just have to be careful in the wet, wheel spin could have the boost come on quick with the attendant loads of torque.
Besides the higher/different power delivery, you can sense the flattening torque curve as you hit 5500 rpm in the K16s. Literally like running out of puff as the smaller turbos/turbines/impellers start choking up... With the K24s I was banging off the rev limiter the first few times as you don't have that telling you it's time to change up. It will pull like a train to the limiter...
It just feels and delivers so much more on the K24s. I have no regrets and in fact relish having made that change. And you will enjoy this on any clear stretch of highway, not just the track....

Pierre - what have you decided?
I might want to do the same - so maybe a group buy or something?
Although my car is the 408BHP, Id like it closer to 500BHP, but dont want to compromise reliability
