Additional modifications consist of LED exterior lighting, a GT3-style rear decklid with carbon fiber spoiler, 19” Forgeline wheels, an Auto-Blip Intelligent Downshifts module, a DSC Sport PASM controller, and Fabspeed exhaust components. This custom 997 is now being offered for auction by its seller out of Kansas.
As an all-wheel-drive model, the Carrera 4S features wider bodywork than a standard 997 Carrera. This example is finished in GT Silver Metallic and features an optional rear window wiper and yellow ceramic brake calipers. Modifications include a genuine 991 front spoiler lip, LED daytime running lights, LED side markers, Morimoto XB LED taillights, and a carbon fiber-reinforced plastic GT3-style rear deck lid incorporating a ducktail spoiler and a full carbon fiber wing. Additionally, 19” Forgeline GA1R lightweight alloy wheels have been mounted with Michelin Pilot Sport 4S tires measuring 255/35ZR19 and 315/30ZR19 front and rear. Clear paint protection film has been placed ahead of the rear fender arches, and very minor paint chips are noted. Detailed images are provided in the gallery along with a clean CARFAX report.
Inside, the driver is greeted with Cocoa Special Leather, matching floor mats, and deviated stitching along the seats, dashboard, doors, center console, and rear side panel, as well as a contrasting Alcantara roof liner. Options also include Adaptive Sport Seats, a leather-wrapped three-spoke multifunction steering wheel, the Bose High-End Sound Package, a 6-disc remote CD changer, Navigation for PCM, a fire extinguisher, a Sport Chrono stopwatch dial, and metal door sills with model insignia. Modifications consist of an Auto-Blip Intelligent Downshifts module, a DSC Sport PASM controller, and a Rennline magnetic phone mount. Minor wear is noted on the driver’s seat bolsters and on both sides of the center console, near the seatbelt latches. All gauges, electronics, and accessories are confirmed to be in proper working order.
The original naturally aspirated 3.8-liter flat-six has been professionally rebuilt by Vision Motorsports with displacement increased to 4.2 liters and equipped with their custom track package, which includes high-performance Chromoly steel cylinder liners, a knife-edged and nitrided crankshaft, forged CP-Carrillo rods and bolts, JE forged pistons, an upgraded IMS bearing, improved oil delivery with an upgraded oil cooler, larger fuel injectors, an IPD plenum paired with a Porsche GT3 throttle body, and a genuine Porsche center radiator. The engine was dyno-tuned by Protomotive and Vision Motorsport, and fitted with all-new belts and hoses. Power is delivered to all four wheels through a 6-speed manual transaxle. Factory performance options consist of Porsche Ceramic Composite Brakes (PCCB) and the Sport Chrono Package Plus, while Porsche Active Suspension Management (PASM) and Porsche Stability Management (PSM) are equipped as standard. Fabspeed sport headers with a competition X-pipe and stainless-steel mufflers are installed, and a catalytic converter will be included with the sale.
This sale will include a clean title, owner’s manuals, a window sticker, a toolkit, a car cover, a battery charger, the factory wheels with tires, the factory rear decklid, and a Fabspeed catalytic converter.
The seller would like you to know: “Thank you for visiting my auction. I have owned this beautiful 997 for about 4 years and have truly enjoyed the car. This is a driver's car and it is ready to be driven. This car rewards the senses for both driver and passenger, especially on winding two-line highways and scenic byways.”

@VaheA for sale?
great car good sell
I have a 2006 Porsche 911 3.6 with a 4.1 liter engine
It did 342 hp and 312 torque on the dyno
Seems like the clutch is a bit weak and once replaced it will do another 20-30 ftlbs of torque
Sold for $66,200

@nick_pa It is an aftermarket bearing from LN Engineering.
Is the new ims bearing the same as stock? Or an aftermarket version?
@chillimd One rear shock was replaced for sure, but as far as I know, that’s all.
@chillimd I’d have to do a little digging to know what brand is installed. I’ll see what I can find for you.. This one is not real stiff though.
@Archer1 Yes, the rear deck looks great even without the wing.
@nick_pa No, not harder to press. But a little trickier…it grabs later but bites a little more than stock. It takes some getting used to, but it’s not difficult.
@Sylverlee I think I still have them. If I do, they will be included.
I also don't see what brand clutch was installed. I'm partial to Promotive for high hp builds. It is stiff though.
Regarding suspension again, to the best of your knowledge, has any component been replaced or upgraded already?
@ 9974.2 (seller)- Beautiful C4S; can the carbon fiber wing be remove leaving rear duck-tail deck lid in place?
What’s the clutch pedal feel like? Is it harder to press than stock? Thanks.
This doesn't include factory headers/muffler right? I know OEM cat not included
@CR_R53 Thanks for the question, yes, both were replaced with new higher-performance parts, as well as the addition of a new lightweight flywheel.
Nevermind, I see both were replaced (and upgraded) on the receipt. I shouldn't have been surprised based on how through everything else was.
Was any work done to the clutch and/or pressure plate when the engine was rebuilt? I didn't see anything mentioned but it seems like a while you are in there sort of thing.
Love it! Tasteful build on a great spec. -- and comes with the added bonus of a KS pick-up (IYKYK) -- GLWA!
@PCARplease Thanks for the feedback. On the question of mileage...I haven't paid close enough attention to it to provide any accurate data, but if I had to guess, I would say that it has decreased slightly, but probably not much more than 2-3 mpg.
@9974.2 First off great communication, thanks for that. Secondly, weird question (mainly just curiosity) what's your mpg look like after the engine was built? A silly question cause why worry about miles per gallon when miles per smile are far more important but I've always been curious 3.8L vs 4.0L/4.2L bored out engines. Thanks
Bid in the amount of $46,000
@chillimd One other note about suspension mods currently on the car...this car does have the DSC Sport Dynamic Suspension Controller with the 3-axis Accelerometer. The controller comes from DSC Sport with much improved characteristics over the stock controller, and there is software available from DSC Sport that allows the driver to further tune the suspension, if desired.
Bid in the amount of $45,000
@chillimd Great question...but I would flip it around a little...if I were considering buying it today as it sits, and if I was planning on taking it to the occasional open track event, then the only thing I'd probably consider doing is upgrading the suspension a little more. I'd probably go with more adjustable upper front suspension mounts, to increase camber. Then I'd probably go with slightly stiffer anti-roll bars front and back, to reduce roll. I wouldn't do much more unless I were serious about track events.
Curious, is there anything you'd be doing next on this car if you were not selling it? I don't see any mention of suspension work, control arms, axles, diff seals.
Bid in the amount of $40,250
@RBradshaw Sorry I missed the second part of your question about the PCCB's: I cannot say for sure, but everything I know about PCCBs tells me these are the original rotors. Original PCCB rotors will easily last for 100,000 miles or more with street driving. At over 34 mm at the front, and over 28 mm at the rear, these rotors have half (or slightly more) of their life left in them. And the pads are at 8 mm. New, these pads are 12 mm and Porsche recommends they be changed when they get to 4 mm.
@nick_pa No, the engine does not burn any oil and I wouldn't hesitate driving it cross-country.
@RBradshaw Yes, the original deck lid comes with the car. And, yes, the GT3-style deck lid can be used without the wing.
@r32fan Unfortunately, I am traveling and won't be able to add a POV driving video.
Bid in the amount of $40,000
Bid in the amount of $35,000
Does the engine burn any oil after the re-sleeves? Would you have any hesitation driving it cross country after purchase? (meaning the buyer would drive it, but if you were in the buyer's shoes). Thanks.
@9974.2 do you have the original deck lid and is it possible to remove the carbon wing and still use the GT3 style rear deck lid? Also, with regards to the earlier comment about the PCCB’s, do you have any knowledge if they are the originals or if they’ve been replaced prior to your ownership? Thanks
Can you add a PoV driving video before the auction closes? Thanks
@nick_pa Emissions testing is not required in my state, but I would have to say no. However, the cat pipes are bolt-in, so relatively easy to swap in/out.
Does it pass emissions as-is? Or do the cats need to go on before taking it to emissions? Or other?
@PORCOR Good eyes. All sweet rides. Others still a work-in-progress.
Is that a blower i see sticking out of the hood of the sweet Chevelle in the garage? I will just take a wild guess that the Mustang is sweet as well.
@Exm3racer As you have probably determined, they are the lobster claw wheels. All are in good to very good condition with very few chips. I do not believe the cats would require a re-tuning, since they are high-flow cats.
Bid in the amount of $32,000
@9974.2 pleas disregard prior message. I found the XRR sport wheels on the spec, so I figured it out. Maybe you can comment on the condition? Also with the cats, would the ecu need retuning if they were installed? Thanks
@9974.2 I thought I saw which wheels the stock ones were but I can’t seem to find it in the listing. Curious which style and size they are. Thanks

@Exm3racer Hello, I do not have photos of the spare parts immediately available. These parts are all in boxes on shelves in a climate controlled warehouse and I’m traveling currently. However, let me know what you’re interested in seeing and I’ll try to get you a photo, or let me know if you have a specific question about the spare parts that I can answer.

@simoncsays Not able to say with 100% confidence, but the auction does include Cat pipes, which are a bolt-in option I purchased with the full Fabspeed performance exhaust. They have never been used, but it is my understanding these should make the car California compliant.
Does this car pass California smog/emissions?
@PORCOR Yes, trailered the car out and back.
Did you send the car to California for the motor rebuild? Drove or shipped?
One of the nice details on this car that would be easy to miss is the AutoBlip Intelligent Downshift module, which is fully adjustable to the drivers preference or driving conditions. If you are not familiar with it, this device blips the throttle automatically during braking and downshifting, which brings the revs up to better match the revs required for the new lower gear. This helps in two significant ways: (1) it eliminates the need for heel/toe throttle blipping, and (2) it helps keep the car balanced at the important entry-phase of a corner.
Bid in the amount of $20,000
@Tgdelb Thank you for sharing your experience and for the vote of confidence!
I am curious to see what the take is on this car. I have a similar 997S built to 4.0 liters and mine is a blast! In my opinion this combination is a very capable midweight chassis with a perfect amount of power. Best of luck Seller. Buyer, you will be getting an amazing ride for certain.

@minimalist There should be a "contact seller" button just above the comments where you can contact me directly.
thank you. still interested in speaking offline as well as knowing more about your PPI and the possibility of seeing the car prior to auction end.
@minimalist I am not sure why that label is there. The mileage on the odometer is accurate, and was 88550 at the time the photos were taken. It has been driven less than 100 miles since then. The engine has about 2000 miles on the new build.
can you speak to the label of TMU? are chassis miles accurate on the odometer and it is the motor rebuild you are referring to?
@bphillyer Thanks for the very kind feedback. Yes, with all the mods, I've always tried to keep Senna's quote in the back of my mind: “When you are in the car, you are so focused, you are so concentrated, you don’t think about anything else. You are just driving, you are just feeling the car, you are feeling the track, you are feeling the tires, the brakes, the engine, everything is working together.”
Beauty.
Good job with mods. Looks like your true interest is in improving the car, as opposed to a blind search forspeed. At least to. me, you’ve done your research.
Great wheels, too -19” Forgeline GA1R lightweight alloys. My 2010 997.2 GT3 has the same!
Ditto with the EXCELLENT DSC Sport PASM controller, which makes a huge difference.
GLWTA!
@02silverbullet Yes, only about 2K miles with the new engine. No track miles. All open road miles. We get it out on weekends for 1-2 hour drives in eastern Kansas, and over the past few years we've taken 500+ mile road trips in it with others to drive the twisty Pig Tail Scenic Byway and other fun driving routes through northern Arkansas, southern Missouri. But I have other cars and other projects. Besides, I enjoy working on cars almost as much as love driving them.
Looks like the new engine only has ~ 2k miles on it … Why has it been used so sparingly? How many of those are track miles?
@luis.seneriz Yeah, Todd at Protomotive is awesome. I included the dyno chart in the photos. It is worth noting that it is a record of wheel HP and torque, so flywheel HP and torque is going to be and estimate. The best estimate I have is 400 - 425 HP and 350 - 375 ft-lbs of torque.
Bid in the amount of $15,911
Definitely like the car. protomotive in Arkansas is awesome, Tod is tha man. Any idea on horsepower and torque? Thanks.
One additional item that wasn't noted in the description above, but some of you may have picked up on in the photos, is the super lightweight Antigravity Lithium battery. It has their built-in jump start capability called RESTART, and it also has the optional remote monitoring capability and a Lithium-battery specific charger.
@minimalist Thanks. Well, given the upcoming holiday weekend, I already have an appointment for tomorrow morning to have a PPI performed, and I will post that report as soon as I can.
Hello. Nice color spec. Is there some way to contact you directly? Are you open to a PPI at my expense prior to auction close? Thank you, David
@PORCOR The best I can say is that it I recall seeing it run up between 4 and 5 at higher RPM. But it is not something I recall being too focused on to say for sure. You also asked about a deeper sump, and I discussed this and other devices, such as an Accusump, with the guys building my engine. If I were planning on tracking it, I would have gone with the Accusump over the deeper sump. But I wasn't really planning on tracking it, and haven't ever tracked it.
I trust you. From memory do you have an estimate of high pressure?
@PORCOR As you know, the pressure changes with RPM. So, I will try to make a short video in the next day or two showing the oil pressure gauge with varying RPMs.
I am not positive but i thought the porsche gauges recently are PSI with readings of 10-50 psi. On another Porsche the 10-50 gauge reads considerably lower than the digital gauge. But , what reading does it show at higher rpm's when warm. I see the engine people did work on the oil pump so am curious as to the higher rpm readings. They did not suggest a deeper oil sump on the build?
@Hindley-Milner You're right. However, I suspect if it is PSI then the numbers 1-5 must represent 10 to 50 PSI.
@9974.2 I certainly hope, for all owners’ sakes, that it is bar, as a gauge going from 1 to 5 psi would be very useless indeed.
@PORCOR Side note -- I actually don't recall ever looking into whether the oil gauge displays in PSI or Bar. I guess I've always thought of it as Bar, but it may actually be PSI.
@PORCOR Regarding your question about the oil. The pressure reading at idle in that photo is just under 2 bar, which is normal at idle with a warm engine. I am currently running Mobil 1 Racing Oil 0w-50 Full Synthetic.
@PORCOR Great question. No, the brakes are not close to the minimum thickness. PCCB rotors are designed to be 34/28 front/rear from the factory, with a design for 0.5 mm of maximum wear, so 33.5/27.5 front/rear. However, the min thicknesses etched on these rotors are 33.7/27.7 front/rear, which may just be Porsche's way of communicating additional safety margin. Regardless, currently the rotors are measuring close to 34.1/28.1, which means they still have well over half their designed life remaining.
Am i correct in assuming that the brake discs are close to reaching min. thickness specs? Can't see the tach when you are showing the oil pressure. Was it 20 lbs at idle or? What oil and viscosity are you running? Really neat car and GLWTA
