  • VIN: WP0AA299XTS322832
  • Mileage: 104,650

  • Lot #: V-0043603

Making its debut for the 1996 model year, the Carrera 4S combines wide bodywork from the 911 Turbo with a naturally aspirated flat-six engine. Finished in Black over a matching interior, this 1996 example features an upgraded 3.8L engine, 18” Fikse wheels, Bilstein coilovers, OEM Sport seats, a 996 GT3 steering wheel, and more. This one-owner 993 Carrera 4S is now being offered for auction out of California showing less than 105k miles on the odometer.

The C4S derives its widened fenders, bumpers, and red brake calipers from the 911 Turbo while retaining the standard Carrera’s speed-activated rear spoiler. Finished in Black, this example rides on a set of aftermarket 18” Fikse FM10 3-piece forged wheels and has been lowered on a set of Bilstein PSS9 coilovers. Other equipment includes integrated front fog lights, heated and power-adjustable mirrors, and dual exhaust outlets. Detailed images are provided in the gallery along with a clean CARFAX report.

The Black partial leather interior has been modified with Sport seats, a 996 GT3 steering wheel, an upgraded stereo featuring an Alpine head unit, and a trunk-mounted McIntosh amplifier that powers DynAudio speakers throughout the cabin. Factory equipment includes an electric sunroof, air conditioning, power windows, cruise control, and central locking doors. Additional modifications include Ruf aluminum pedals along with a Passport radar detector and laser jammer that have been hardwired and installed with a covert display on the steering column. The seller notes that the sunroof is stuck but all other accessories are working properly.

The air-cooled flat-six engine has been rebuilt and now displaces 3.8 liters with new cylinders and pistons, RS camshafts, and an upgraded intake and throttle body. All four wheels are driven through a 6-speed manual transaxle. Additional modifications include a lightweight clutch kit and 100-cell catalytic converters. The seller notes that the tires should be replaced, that a third-party inspection was completed on February 14, 2024, and that service was performed in April of 2024 to remedy the boot issue noted in the inspection. Additional service includes an oil service and brake fluid flush. 

This sale will include the owner’s manuals, a window sticker, a toolkit, an air pump, a battery charger, the original steering wheel, and a clean title.

The seller would like you to know: “Thank you for visiting my auction. I am the original owner of this car and have loved it from the very first day. This 4S has had thoughtful modifications that have improved performance and looks. Maintenance is up to date. Congratulations in advance to the next (and only second) owner of this classic.”

    @Dadbug yes, this car was warmed up and essentially driven around the block and on a trickle charger to keep the engine and seals primed.

    Smog Test from 2014 shows the odometer at about 103k. Was the car just not driven for 10 years?

    @sswang01 reserve is kept private. This system is highly effective. Please assume your bid can be a winning bid as they are contractual and the seller has the right to accept the high bid even if it is under the reserve. Thank you.

  • sswang01 (registered bidder) 4 weeks, 1 dayago

    Excuse my ignorance, I'm more of a BAT buyer. Does pcarmarket let you know when the reserve is met? It says this is a reserve auction but I can't see if it's bet met or not

  • Smashing-Gears (seller) 4 weeks, 1 dayago

    This car has always been serviced by S-Car-Go, a Porsche dealership service center or a current certified Porsche tech (who also remedied this finding).

  • sswang01 (registered bidder) 4 weeks, 1 dayago

    @WReiter Yes, sorry for the confusion. It was in the inspection report from a few months ago but it brings to question. What kind of care was taking care of the car if it was previously clamped down with zip ties.

  • WReiter (registered bidder) 4 weeks, 1 dayago


    Oh ok. I thought that you meant now (I didn't see any zip ties in the current video (of the rear boots). Thanks.

  • sswang01 (registered bidder) 4 weeks, 1 dayago

    @WReiter Inspection report page 5. Cv boots clamped down using zip ties. Front and back. And mentions the oil leak

  • WReiter (registered bidder) 1 monthago


    Where do you see zip ties??

  • Smashing-Gears (seller) 1 monthago

    The latest video report addressing the BR Inspection Report findings has been attached by a Porsche certified tech. Also The historical service records are uploaded.

  • sswang01 (registered bidder) 1 monthago

    Why in the world were the CV boots clamped down with zip ties?? Wonder if there are zip ties holding anything else together. Was the oil leak addressed?

    Check the inspection

    Tires gone

    Great build just wish you cleared up these few small issues. I will be bidding with a tighter budget in might for these items.

  • Smashing-Gears (seller) 1 monthago

    Just a heads-up that I will be tied up a fair bit until later tonight and at least through lunch time on Saturday. I will make every attempt to reply as soon as possible. Thanks

  • larrygk (registered bidder) 1 monthago

    @Tarek307 See the inspection report re leaks.

  • larrygk (registered bidder) 1 monthago

    My experience on HP gain according (to talking) to S Car Go in the past is it is about 60 increase.

  • Smashing-Gears (seller) 1 monthago

    @Tarek307 I am going to scan the records this weekend and hopefully post them by Sunday.

  • Tarek307 (registered bidder) 1 monthago

    @Smashing-Gears Thanks for your reply, i looked through the records and don't see any invoice for the 3.8 Build, is that available?

  • Zjs2057 1 monthago

    Bid in the amount of $50,000

  • Smashing-Gears (seller) 1 monthago

    @Tarek307 There are no observable leaks at this time. If possible, I will try and put the car on a rack to take undercarriage pics and post them this weekend.

  • Smashing-Gears (seller) 1 monthago

    @Tarek307 The paint work that was done was due to the rear fenders being slightly rolled out to accommodate a wider rear tire set. This car was initially listed on a local site in October. After it became clear to me that they lacked market reach and sales expertise, I pulled the car back. Mechanically, all is in working order at this time and there are no triggered warning lights. Even the sunroof has been working (as noted in the original description, this does stick intermittently).

  • Tarek307 (registered bidder) 1 monthago

    Also does the seller plan on taking actual undercarriage photos so we can see the engine? These ones sticking the camera under the car with it on the ground aren't very telling. Are there any leaks?

  • Tarek307 (registered bidder) 1 monthago

    paint meter readings not in mils in see..haven't tried to convert but looks like some paint work has been done, can you elaborate on that? Also the car has been for sale since October at least of last year, is there any reason its been for sale for so long? Anything mechanical at all you can mention? warning lights?


  • Smashing-Gears (seller) 1 monthago

    The paint report has been posted to the gallery.

    Bid in the amount of $35,000

  • Smashing-Gears (seller) 1 monthago

    @Guyc2 understood. I'm just posting my recollection of my discussion and noted that the car was not dyno'd nor validated using an alternative method.

  • Guyc2 (registered bidder) 1 monthago

    @Smashing-Gears --thats very optimistic as the 3.6 is 282hp vs tt 408hp, and iirc a 3.8 conversion is maybe 10%, which leaves it 100hp light. ( I toyed with a conversion back in the day on my C2).

  • DonnyB 1 monthago

    Bid in the amount of $31,000

  • Smashing-Gears (seller) 1 monthago

    @Guyc2 I would've loved to have had it dyno'd, but didn't. Anecdotally, I remember Rob (owner at S-Car-Go) saying it would start approaching the Turbo's 0-60 and 1/4 mile times, but again, this hasn't been validated.

  • Guyc2 (registered bidder) 1 monthago

    @Smashing-Gears --thanks-- how much power did you gain? Ifmit was on a dyne it will help the auction

  • Smashing-Gears (seller) 1 monthago

    @Guyc2 at just under 69,000.

  • Guyc2 (registered bidder) 1 monthago

    how many miles on the rebuilt engine, and the pss9s?

  • Smashing-Gears (seller) 1 monthago

    @zbb0730 Included are the original stereo speakers and 4-spoke steering wheel. Unfortunately, I currently cannot find the original stereo head unit (I will continue to look for it, and send it along, as I find it hard to believe that I don't have it). I do not have any of the original engine/suspension parts. Although this car has never been tracked, S-Car-Go Racing in San Rafael, CA did all the performance mods. I wanted to upgrade performance for occasional spirited driving .

  • Smashing-Gears (seller) 1 monthago

    @77911s I will look for the paint meter readings, as I believe I have a report from late 2023. I will also look to pdf the service docs. The most recent inspection and service (Feb/April 2024 respectively) included an oil service, brake fluid flush and inner/outer clamps for boot repair for both axels. Over the history of the service reports, there is nothing remarkable to note.

  • zbb0730 (registered bidder) 1 monthago

    Do you have orginal parts to go with the car? Why the changes?

  • 77911s (registered bidder) 1 monthago

    Beautiful car!
    Any chance you could provide paint meter readings?
    Service docs would be helpful as well!
