In the same year with the coupe version, Ferrari also brought the GTS Turbo. Like the GTB version, it was also specially built for the Italian market in order to avoid the extra taxes for the models with a displacement larger than 2,0 liters. The car remained into production from 1986 to 1989 with 828 units produced.

The GTS Turbo was in fact a turbocharged version for the 328 GTS, but powered by a 2,0 liter engine.

Like the 328 GTS, the GTS Turbo model presented a softening of the wedge profile of its predecessor, the 208 GTS Turbo, with a redesigned nose that had a more rounded profile, that was complimented by similar treatment to the tail valance panel.

The revised nose and tail sections featured body colour bumpers integral with the valance panels, which reflected the work done concurrently on the Mondial 3.2 models, with which they also shared a similar radiator grille and front light assembly layout.

The exhaust air louvers behind the retractable headlight pods disappeared, with an increase in the size of the front lid louver introduced on the "QV" series, and a new style and position of exterior door catch was provided.

The interior trim also had a thorough overhaul, with new designs for the seat panel upholstery and stitching, revised door panels and pulls, together with more modern switchgear, which combined to reflect the external updating details.

The GTS Turbo model had some differences that differentiated it from its normally aspirated cousin, notably a different engine lid louver and raised central panel arrangement, a NACA duct forward of each rear wheel arch, and a row of five slim exhaust air slots in the rear valance panel. It also featured the rear of roof aerofoil, which was optional on the 328 series, as standard equipment.

Like the coupe version, the GTS Turbo was powered by a 2,0 liter V8 engine, with a bore and stroke of 66.8mm x 71mm. The engine retained the Bosch K-Jetronic fuel injection system of its predecessor, but was fitted with an IHI turbocharger with a Behr intercooler operating at a boost pressure of 1.05 bar, with a Marelli MED 807 A electronic ignition system, to produce a claimed power output of 254bhp at 6500rpm.
