|Fondly known as the Hakosuka (“box Skyline,” chassis code KPGC10), the 1971 Skyline was the first to wear the world-renowned GT-R badge—for gran turismo racer—signifying that this was no run-of-the-mill Skyline GT. The inspiration for the GT-R was an early race special based on a regular, previous-generation S50 Skyline 2000GT that credibly competed with a specially-constructed Porsche 904 GTS in the 1964 Japanese Grand Prix, finishing second, amazing everyone involved and giving Porsche a scare. Now, a bit of history: the Skyline originated not as a Nissan at all, but rather as the flagship of the Prince Motor Company. They developed the predecessor inline-six engines that powered the GT-R’s ancestors, and former Prince engineers ultimately designed the Hako’s S20 motor. In fact, the Hako itself started life as a Prince design, but Nissan purchased the company in 1966 and finished work on the Skyline. Nissan rightly realized the brilliance of the Skyline concept, kept the “Skyline” moniker around for successive cars, and continued to develop the engine—and that engine is magnificent. Displacing 2 liters and capable of revving to 10,000 RPM (virtually unbelievable in the era, when only Formula 1 engines could come close), the triple-carbureted engine produces 160 horsepower stock. The Hako’s lithe 2,400 lbs. weight and advanced rear semi-trailing arm independent suspension mean that it is a fast, sweet-handling car by any standard. Original 2000GT-Rs are extremely rare and highly prized, commanding six-figure prices in good condition, so it’s no surprise that clones abound. And while modifying an original Hako GT-R will bring the ire of traditionalists in real life, in Forza 4 you can customize the 2000GT-R pretty much any way you’d like—whether it’s dropping in a RB26DETT, converting to AWD, or deleting the front and rear bumpers for a clean race-ready look.|
— Official description 
The 1971 Nissan Skyline 2000GT-R - abbreviated as Nissan GT-R '71 - is a FR sports car by Nissan that debuted in the Motorsport Legends Car Pack for Forza Motorsport 3, and is featured in all subsequent main series titles.
The 2000GT-R was introduced as the fastest model of the C10 codenamed Skyline generation. It was only available for the Japanese domestic market and produced in saloon and coupé body styles. It was replaced in 1973 by the Nissan Skyline H/T 2000GT-R.
It is powered by an S20 codenamed two litre inline-six engine with 160 hp (119 kW) and 133 ft·lb (180 N·m) of torque, which were achieved by using a double overhead camshaft (DOHC) design accomodating 24 valves and triple Mikuni-Solex carburetors. The 2000GT-R can launch from 0 to 60 mph (97 km/h) in seven seconds, an impressive feat for a 1970s era sports car.
Due to a kerb weight of 2425 lb (1100 kg), it is heavier than most cars of its type and vintage including the Nissan Fairlady Z 432, although it does have a fairly neutral weight distribution due to carrying only 54% of its weight at the front. In addition, it also has all-wheel independent suspension consisting of front struts and a rear semi-trailing arm suspension for strong cornering performance.
The 160 hp (119 kW) makes the 2000GT-R noticeably more powerful than most sports compacts of the late 1960s and 1970s, allowing it to have adequate acceleration for lower performance classes. It is well composed in corners but suffers from slight body roll at higher speeds.
The 2000GT-R has quicker gearing than the Nissan Fairlady Z 432, allowing it to have faster acceleration despite sharing the same engine. However, given the Fairlady Z's lower weight and better weight distribution, the 2000GT-R also has somewhat more difficult handling.
