Model car kit Porsche 911(992) GT3 RS-Alpha Model 1/24 scale 

The Porsche 911 GT3 is a high-performance homologation model of the Porsche 911 sports car. It is a high-performance model line, which began with the 1973 911 Carrera RS. The GT3 had a successful racing career in the series national and regional single-brand Porsche Carrera Cup and GT3 Cup Challenge, as well as in the international Porsche Supercup in support of the FIA ​​​​F1 World Championship.
The “GT3” nameplate was introduced in 1999 as part of the first generation of the Porsche 996 model range (commonly known as 996.1) as the homologation model for cars entered in the FIA ​​GT3 cup. Like previous Porsche 911 RS models, the 996 GT3 was focused on racing and therefore was free of elements that added unnecessary weight to the car. Soundproofing was almost completely removed, as were the rear seats, rear speakers, sunroof, and air conditioning, although automatic air conditioning and CD/radio became no-cost optional add-ons.

The 996 GT3’s engine set it apart from most other 996 models, although it shared the same basic design as the standard so-called “dry sump” flat-six engine. The engine is naturally aspirated and is based on the unit used in the 962 and 911 GT1 racing cars. That engine was known as the “Mezger” engine, named after its designer Hans Mezger. The engine uses the original 911’s versatile air-cooled dry sump crankcase, with an external oil tank. The 996 GT3 has 360 PS (265 kW; 355 PS), compared to the standard 996’s 300 PS (221 kW; 296 hp). In the GT3 configuration, this so-called “split” crankcase (i.e. the crankcase seam is on the centerline of the crankshaft) uses, instead of a fan and finned cylinders, separate water jackets added to each side of the crankcase to cool the banks of three cylinders with water pumped through a radiator. Therefore, the GT3 engine is very similar to the fully water-cooled 962 racing car engine, which is based on the same crankcase. The 962 differs, however, in that it uses six individual cylinder heads while the GT1/GT3, like the air- and water-cooled 959, uses two cylinder heads, each covering a bank of three cylinders. The GT3 engine could therefore also be thought of as similar to a 959 engine, but with water-cooled cylinders. Until production of the 2004 model year 996 GT3 began, the basic casting used for the GT3’s crankcase was the same as the air-cooled engine. The casting number “964” was visible on the bottom of the crankcase and on areas normally machined in air-cooled applications, but not in water-cooled ones. The crankcase casting was changed in mid-2004 to a “996” casting number crankcase to eliminate this external air-cooled debris, but internally it was the same.

Since the air-cooled 911 crankcase uses the Porsche 356 engine for the transmission mounting flange configuration, the 996 GT3 used a 6-speed manual transmission also of air-cooled 911 tradition. This gearbox has interchangeable gear ratios and is more durable, making it more suitable for racing than the standard 996-type gearbox.

To bring the vehicle’s track performance to the highest level, Porsche equipped the GT3 with larger brakes, a lowered and recalibrated suspension system, lighter wheels and a new front bumper with matching rear spoiler to increase downforce, thus increasing the adhesion. .

Porsche offered a no-cost option for the GT3 called the “Clubsport” package. This option replaced the standard power-adjustable leather front seats with manually adjustable racing bucket seats trimmed in fire-retardant fabric, single-mass flywheel, bolt-on semi-roll cage, 6-point racing seat belt for the driver (in also replacement of the standard side airbags), fire extinguisher (mounted in the front passenger footwell) and provision for a battery switch. The Clubsport option was never offered to US customers, apparently due to the additional DOT crash tests that would have been necessary to allow sales in the US.
