This 1996 Saab 900SE has been extensively modified by Frank Stromqvist of Trollspeed and is powered by a turbocharged 2.3 liter inline-four making 393 horsepower at the front wheels on pump gas. To cope with the extra power, the car is equipped with a 6-speed gearbox from a later 9-3, Quaife LSD, upgraded brakes from a Saab 9-5, and numerous other performance-oriented upgrades inside and out. The bodywork has been updated with a complete 9-3 Viggen body kit, and the seller estimates that their weight-reduction efforts have lightened the car by around 300 pounds. This highly tuned Saab is now offered with a clean North Carolina title in the seller’s name.

The exterior has been modified with a Saab Viggen body kit, including that model’s distinctive hatch spoiler. BBS CH wheels have been added long with Saab 9-5 Aero brakes and Brembo rotors to help cope with the power increase. E-Code headlights and a Saab 9-3 grille round out the visual alterations.

The silver paintwork has a uniform finish, and stock trim for a 9-3 Viggen is present throughout, including the updated taillights with hatch-mounted license plate. The front bumper has been drilled for either a US-market plate bracket or a Euro plate. The emblems are Koenigsegg “Ghost Squadron” items.

The stock seats have been replaced with Sparco R100 seats and color coordinated Sparco racing harnesses for both driver and passenger, though the factory belts have been retained and can still be used. The seats have Swedish flag colored accents that are nicely matched to the blue harnesses. The seats are mounted to OEM 9-3 rails and are power adjustable. The front door panels are still fitted, but much of the rest of the interior has been stripped, and the seller estimates that around 300 pounds have been removed from the car.

The dash, instrument cluster, and steering wheel are Viggen items, and an aluminum fascia has been fitted. The factory stereo and dash display with analog clock were retained. This car is equipped with Saab’s optional automatic HVAC system, though the A/C equipment has mostly been removed.

The engine builder and owner of Trollspeed used to run Saab’s factory race efforts and now builds motors for Andretti Motorsports. According to the seller, this B234R engine is capable of making up to 900 horsepower and is balanced for up to 8,800 rpm. The engine is mated to the 6-Speed F40 gearbox from a later 9-3 Sport Sedan using the bellhousing from the 9-5 Turbodiesel, a European market-model that was only made for two years. The build includes the following:

Engine Trionic 5 ECU (T5) 276 Cams with Trollspeed Racing Cam Gears Trollspeed Ported / Polished cylinder head (Modified to allow room for 276 cams) 0.5mm oversized JE Pistons (sourced from the superior metallurgy production) Trollspeed reinforced cylinder head Verdi rods Garrett GT30-71R BB / Honeywell hybrid turbo (.50 / .86) with less than 1,000 miles ETS (Prototype) Viggen performance intercooler; First example ETS fabricated Balance-shaft delete Bosch – Porsche 911 hi-output fuel pump 3″ stainless turboback exhaust; Lava wrapped downpipe; Magnaflow muffler OEM radiator, two speed fan/shroud, condenser, compressor delete; Short belt Eurowise Performance one-off radiator shroud with dual 10″ Mishimoto slimline fans; Wired into unused OEM 2 speed fan harness OEM hoses replaced with Samco black silicone performance hoses Eurowise Performance one-off intake, charge pipe, catch can, and heat shield Tial Sport 50mm type-q BOV with V-band flange welded very close to throttle body Abbott Racing turbo delivery pipe Calico “jet black” ceramic coated / Honed exhaust manifold with ARP studs Taliaferro ‘Fog light intake’ Taliaferro poly racing engine mount / suspension mounts

Frank Stromqvist built and road tuned this engine personally. The attached dyno sheet shows a peak power figure of 393 horsepower at 5,600 rpm, though the seller notes that based on the strength of the build the engine can take substantially more air, fuel, and boost than it is presently. The Trollspeed-prepared Rallycross cars are based on the same powertrain and produce over 900 horsepower. Frank Stromqvist now builds and tunes vehicles for Andretti Motorsports, including cars used by Tanner Foust, Scott Speed, and Anton Marklund. The seller estimates the mileage on the various components as follows:

Chassis: ~141,000 miles

Turbo: ~1,000 miles

Engine: ~16,000 miles

Clutch: ~3,000 miles

Transmission: ~6,000 miles

A video featuring this car, including a dyno pull and some street driving is attached above. It won people’s choice at the 2014 Saab owner’s convention, beating out numerous other NG900s, OG9-3s, and Viggens. The car has also been featured on the Saab enthusiast site Saab Planet. The seller has provided an additional video of the car accelerating.

The NG900 is the lightest modern Saab, and with this build it should be a very strong performer. The seller notes that the car is easy to drive, and has returned 34 mpg on longer highway trips.
