Just a heads up that Suncoast has a pretty good deal on their X51 factory kits for the MY05 through MY08 S cars.

$9500 vice over $16,000.

Still good chunk of change, but if someone had a plan to rebuild, this is a perfect kit.

One thing I am not sure, since you MUST flash the ECU for extra power, then is dealer install A MUST? or can an indy do this as well?

They are asking 3395 for the airbox alone!

chago996

thats a great deal. sport exhaust alone is $3050

FYI - I just called my Indy and he said "JUST TO DO Cylider heads" it's a 22hr job!

Hey Alex, which Indy do you use?

alexb76

Blitzkrieg, off Main on 1st.

translate to american please!

what does X51 get you?

alexb76

Well, you could have just followed the link, but here is the kit:

My guy said just doing the Cylinder heads is a 22hr job... translation to English, $$$$

chago996

381 hp (bump from 355) and 306 torques (up from 295), nice sound, and a hole in wallet

maroli

so from start to end, this looks like a 15k job. That's the difference between a used 997 C2S and used 997 GT3

pissedpuppy

yeah, I meant what does it give you in performance, not a bill of materials (thanks chago!)

All that money and effort for 7% increase in power - no thanks.

There is an important factor that must be taken into consideration if anyone's car has 25k miles or more. For cars 25k miles or more, page 2 of the Porsche Technical Information "Performance Increase Kit Installation Instructions (I No. X51)" clearly states that - and I quote - "if the engine to be converted has over 25,000 miles (40,000km), the crankshaft main bearing and the connecting rod bearings must also be replaced. If there is obvious wear on the rod bushings (scored), the connecting rods must also be replaced."

This should be taken in consideration if anyone's car has 25k miles or more on the motor because it will add a substantial amount of expense on top of the cost of the kit (even if discounted) plus labor.

The Powerkit only makes sense if you can find an used car with it already on. While I absolutely love the kit, if I had that amount of cash nowadays to spend on a car that is, at best, 3 to 4 years old, I would add that to the sales proceed of the car as is and buy a Turbo, GT3 or a 997.2 Carrera or Carrera S. Yes, my car has 381 hp and 306 lb.ft of torque which is almost the same as a 997.2 Carrera S but, in the latter case you get more than just a power increase - you get all the other improvements in a better engine design, chassis and electronics. The newer the 997.1 Carrera S, the less it makes sense to invest in this, as the price gap between the choices mentioned narrows markedly. I say this from my own experience.

Now... a 2006 Carrera S with X51 in it and miles in the mid 40k range for $55k or nearest offer is the way to go since you save the $15k-20k over getting a 997 Turbo, GT3 or 997.2 car. Just a thought...

I agree with Cyber... this is GREAT for people who are already rebuilding their engine, otherwise, the upgrade is absolutely not worth the effort and/or cost.
