Vehicle Details

This 1991 Porsche 928 GT 5-speed manual has been comprehensively with no expense spared (over $132,000 in receipts and many were lost, at least $150k spent on this incredible restomod build w no stone left unturned) upgraded in all areas after being taken completely apart to slightly change the color with a bare metal respray that cost over $29,000 all in! Extremely clean and straight car the underbody is so flawless and unbelievably clean with no dents or flaws it's amazing see the images and I have lots and lots of videos to share so reach out to me and I will do that I think I have 14 or 15 videos.

The upgrades include and not in order of importance a Whipple style supercharger, fully built engine with 8.1 to 1 compression with forged pistons, Pauter rods with arp 2000 studs and fasteners throughout it has the crank oiling mods it's a 5.4 liter original block w fresh Nikasil cylinders, extensive cooling and charge cooling upgrades, coil on plug ignition which is programmable along with the custom fuel injection setup with billet fuel rails which are thermally protected with RC balanced injectors everything is balanced and blueprinted has a brand new (2023) UTI harmonic balancer along with a brand new racing timing belt water pump coolant valve cover gaskets and green oil pan gasket the engine is built for 30 PSI of boost and it's only running 14 lb of boost and it screams all the way to 8000 RPM! The valve train is built to handle the RPMs and the absolute best of everything has been used throughout. The headers are ceramic coated inside and out then thermally wrapped with the most effective thermal protection you can get. It uses a large oval throttle body on the supercharger and custom cold air only intake which seals up underneath the hood so all the air must come in through the hood scoops only again the headers below have been effectively thermal wrapped and the underhood temperatures are very low compared to any stock one every attention to detail has been taken valve covers match the body color all of the nuts and bolts and fittings have the correct gold color and beautiful detailed installation with care. The car has a 600 horsepower clutch in it which drives like a dream, the transmission is flawless and has been gone through and upgraded as has the torque tube the motor mounts all the hoses and belts everything's gone through. It has new adjustable coilover shocks with h&r springs and has been corner weighted and height set it has aluminum hatted drilled vented brake rotors in front and drilled vented rears on GTS brakes w stainless steel brake lines all around, it also has the updated GTS mirrors which are way better looking I do have the stock ones I also have the stock airbag steering wheel in great shape along with the stock shifter handle and boot which is in great shape I also have a box full of original parts and a folder from Porsche with a "certificate of authenticity" with all the options including rear a/c which works great etc, very nice to have for sure. The car has a Momo anatomic steering wheel on it now and a Momo shifter it has an adjustable throw shift mechanism also the differential is electronically activated for full posi lock up when spin is sensed with a light coming up on the dash it has the safer under dash leg panels and digital dashboard componentry. It has brand new condition BBS modular Wheels in 18" with 245s in the front and 295s in the rear they are Michelin pilot sport cups probably the best tires made by any company and they're in like new condition as are the brakes as is everything! The stereo system in the car is incredible and super cleanly installed has 14 speakers again cleanly installed with minimal space intrusion on the subs but beautiful it has Bluetooth and the sound is the best I've ever heard in a car it's amazing no expense was spared! The car just had a Royal purple oil and filter change with no miles yet. The exhaust system is incredible equal length headers again ceramic coated inside and out and thermally wrapped which go into 3" pipes which Y down into a 4 inch pipe everything is TIG welded and polished it's absolutely gorgeous the sound at 8,000 RPM is incredible it's not too loud but at full throttle and RPM it's definitely something you can really hear I would say it's a perfect exhaust for any amount of driving that you like to do no drone at all this was no cheap date! Even the windshield washer squirters are heated and light up with the headlights!! The car has the clear Euro front side markers and I also have the original orange ones too. I also have a high down Force rear wing for it which bolts on with no modifications takes about 10 minutes to switch and you can really feel it above 80 mph so if you're going to take it for any track days I would absolutely use it it actually looks really nice too I just went back to the stock Wing though for road use the front spoiler is in brand new condition the custom metal front louvered and NACA ducted front underpan is literally in perfect condition no flaws. No chips in the windshield the sunroof and the windows work great the rear windshield wiper has been correctly deleted and it has perfect condition window tint on it, all the interior panels are unblemished from Sun no warped rear panels underneath those side rear windows like so many cars have the car has a new battery and brand new UNI air filters which are the only aftermarket style filter I would ever use they allow zero dirt in unlike k&n style filters which I would never ever use, UNI filters are dirt bike style dual staged oiled foam air cleaners and caged inside too, the best! The steering rack ball joints tie rods etc we're all done while the car was apart whether they needed it or not the car has extra heat shielding on the transmission tunnel area which is great because these cars normally have some heat penetration there which on this car that it doesn't because the headers are fully wrapped with effective thermal and then the body has the thermal inside that transmission tunnel area. I would be happy to get on a video phone call with anybody and do a cold start up and walk around on the spot if desired. This has to be the cleanest straightest underbody on a 928 out there lot of people think the GT is the best car they made ever it has the GTS upgrades to the dash and differential this has the GTS mirrors but the GTS was a little heavier of a car, the color is so good in person you just have to see it to believe it everyone who does loves it! The car can be driven daily or used on weekends or taken to car shows whatever you want it starts immediately and runs smooth very normal to drive and when you step on the gas it's much more fun than any normal 928 and then some and then some better handling better braking more power more acceleration better sound better stereo system improve shifting better wheels and tires better brakes better suspension Devek sway bar components etc..... Absolutely all services were just done and the timing belt used is the absolute best available and lasts three times longer than the normal Gates belt you could feel the difference in your hand, it has the Porken tensioner of course which is also new and never needs any adjustment unlike stock which must be retensioned after use then every couple yrs max. This belt is good for 15 years and is brand new right now. In the driver's side front fender you'll see aeroquip lines a tilton pump and aluminum catch cans and breathers etc for the PVC venting REALLY well done and self returning so never have to empty it there are zero cracks in the dashboard or dash pod interior is in great shape and very comfortable and again that stereo wow! I want to be able to share all the images I have which eBay wouldn't take them all and I have many many videos that you definitely want to see that go into extreme detail especially in the underbody area etc this car is a keeper and so fun to drive and so beautiful to view it's really a special car I do have the luggage cover for it also from Porsche. Absolutely a special car, excellent model (GT)

THIS CAR IS NOT STOCK SO FOR THOSE WHO WANT A BONE STOCK CAR WHICH ONE IS NOT FOR YOU HOWEVER FOR ANYBODY WHO WANTS THE ABSOLUTE BEST COMPONENTS YOU CAN PUT ON A VEHICLE WITH MORE POWER BETTER HANDLING AND BETTER BRAKING WITH A MUCH BETTER INTERIOR EXPERIENCE AT THE HIGHEST QUALITY LEVELS THIS IS A MUST-HAVE ITEM PERSONALLY I WOULD RATHER DRIVE THIS THAN ANY OTHER STOCK 928. IT'S NOT EVEN CLOSE! AGAIN THE ENGINE WAS BUILT FOR 30 LB OF BOOST WHEN IT WAS FIRST BROKEN IN THERE WAS NO BOOST IT WAS USING AN INTAKE MANIFOLD FOR THE 1ST 1,000MI THEN IT WAS USING THE LOW BOOST PULLY FOR 2500MI (STILL HAVE IT) NOW APPROXIMATELY 5K TOTAL MILES HAVE BEEN PUT ON SINCE BUILT, ZERO MILES ON ALL FRESH MAINTENANCE ITEMS MENTIONED

Also I have polished intake tubes for those that don't want to utilize my cold air only to the underside of the hood set up that I built that come with the car I have a bunch of spare lug nuts and all the Porsche parts that came off including the original oil pump, the pump in the car now has a taller gear which gives more volume not more pressure which is an excellent upgrade along with the drilled crankshaft for high RPM oiling etc etc etc we should really talk I have a lot more I could go into and I'm sure I'm forgetting a lot of stuff here but you will not find a cleaner straighter nicer more updated better performing 928 manual transmission at least I haven't seen any, I look forward to questions and comments and let me say now and again the car is not stock I'm not looking for haters who want everything to be bone stock this car is not for you please keep your negativity to yourself everyone else please join the party.
