The dealer had mentioned a x51 package for my 2001 c2. he was looking for individual parts to give me the price. suncoast porsche I know its an air box , header and exhaust, anything else? Does anyone have a pic of this kit, apparently the air box is beautiful to see. how much power does it produce. the reason iam looking at this is to keep my warranty with porsche parts. thanks
The X51 kit was never marketed in the US for 3.4l cars. As such, it is a real pain in the ***, and nets 20 to 30 hp. You will not likely keep your warranty with it. (Warranty on a 2001?) It does not include an airbox. It does include: Intake Headers Heads Cams & lifters Third radiator kit Oil pump & sump (the motorsports oiling kit) It should include a new map for the DME, but that won't help you if you have a US DME. No part of it is particularly "beautiful to see". I don't recommend it.
I believe that there is an X51 kit for the 997 which includes changes to the airbox, headers, etc. Maybe you are referring to that kit? BTW: The X51 kit was like a $17K or $18K option for the 996. My 40th Anniversary has it. Look here for a picture. It is very elaborate: http://pistonheads.com/gassing/topic...=372397&hw=x51
i think its the exhaust pse, headers and air box? and another radiator or something like that. i have no idea when it comes to modifications. i want to upgrade my 2001 which has a 2 year warranty. i love the pse sound so i asked porsche if they had an upgrade kit and he mentioned the x51 pse exhaust 1700 x51 headers 550 usd air box = 995 and he wasnt sure what the other components were. i dont think its the cylinders heads and all that big stuff, i think its bolt ons. i appreciate your comments , at 17 k more ill let then keep it in inventory.

You should re-read my post. Believe me, I know exactly what is involved in the X51 kit for the 3.4l. It absolutely does not include an airbox or PSE.
There was a X51 powerkit for the 996 and it bumped hp to 345 from 320. I don't know what it entailed as far as the 996 is concerned. Dave

^^^^ +1, the x51 for the 3.4 doesnt exist in the US.
Quotes source post: 4711157
Well, I won't say it doesn't exist... But it certainly wasn't meant to.

That is the kit for the 3.6l, which is marketed in the US and includes the same items I listed above.
Ok. I thank you for your answers. i appreciate your time. eric
This isn't related to the OP's question, but the 996 X51 kit doesn't include the 3rd radiator when installed as a factory option.

Are you referring to the kit for a 3.4l or a 3.6l? I wonder why not?
3.6
Quotes source post: 4711809
When you purchased the 3.6L kit to install yourself both the third radiator and the oiling kit are optional. I chose the oiling kit but passed on the radiator because I already had it. I paid $7000 for the kit in 2003. Jim

Yeah, wish I could have done that. I have a third radiator in the storage barn.
