I have a 2 month old C2s with a factory fitted PSE, and have thought about retro fitting the power kit. From what i can see you get exchange heads, a carbon fibre air box, some better headers (the standard ones are crap) PSE, and different mapping.
The Porsche site says you get 380 bhp instead of 355, but is it worth the cost, and has anyone tried a standard car verses a power kit car.
Also, does anyone know the cost of the conversion. I got the impression it was in the 6k mark, but would that be more off the production line? Just could do with a bit more go, and was thinking going down the Fabspeed header, cold air kit and DMS tune route, with hopefully similar output.

The answer to your problem lies here sir. www.porsche.com/all/originmotorspo but if you want the honest, quick answer, no it's not.
But seriously, it may be worth giving DMS or JZ Machtech a call to see what they offer.
Either way it has to be more cost effective than retro fitting the factory powerkit IMHO.

don't think the power kit includes PSE, isn't this a separate option?

take the several £k, invest in some driver training & I guarentee that round a track you will be quicker after the training than if you didn't do the training & had the car modified.

IMO with N/A cars where to get anything more than 10% max requires a lot of spend there isn't much point.
I guarentee that on the road/track the difference an extra 30bhp - or whatever a chip & exhaust gives on a 997 - would be pretty much undetectable.

Get a Turbo !

From the Porsche Website:

Powerkit - Raises power output to 280 kW (381 bhp). Includes modified cylinder heads, exhaust manifolds, ECU, additional radiator (only for manual transmission), carbon fibre air-cleaner housing, aluminium-intake system and sports exhaust system with pair of dual-tube tailpipes in individual design in chrome-plated stainless steel. Note: also in conjunction with Tiptronic S. Available from approx. September 2005

Price £8,241

Given that the Porsche Sports Exhaust cost circa £1.2k, you are looking at £7k for the 26bhp performance upgrade

Obviously the key advantage of the Porsche upgrade is that you retain all the standard warranty, whereas presumably with an upgrade from someone else you risk invalidating the warranty.

Even allowing for the warranty issues, I can't imagine that I'd notice the extra performance sufficiently to justify the price! having said that, I've never driven a car wit this upgrade back-to-back with a standard car to assess the difference, which is the only way to know whether you'd want/need the Powerkit.

Stick with the standard C2S and enjoy the PSE !

As someone else has posted - spending £3,000 on driver training will make much more of a difference to track times than the £7k upgrade, and probably improve your on-road performance, as well as helping you to get the best out of the car and yourself as a driver.

You posted while I was still composing my response - very valid points and consistent with my views.
