GTSt vs GT-R : What is the Difference Between Skyline Models

The question you were afraid to ask, and I don't think I have ever actually answered in a post.

GTS-t vs GT-R: What is the Difference Between Nissan Skyline Models?

The Nissan Skyline is one of Japan’s most iconic performance car lineages, but within the R32, R33, and R34 generations, there’s often confusion between the GTS-t (or later 25GT Turbo) and the more revered GT-R models. Here’s a breakdown of the major differences that matter to enthusiasts, collectors, and tuners alike.

🎯 Focus: R32, R33, R34 Generations

This comparison focuses exclusively on R32 (1989–1994), R33 (1995–1998), and R34 (1999–2002) models — the generations that defined the modern Skyline legacy. Earlier Skylines and other trim variations are not covered in this breakdown.

🧩 Platform & Chassis

• R32 GTS-t (1989–1993): Based on the RWD Nissan HCR32 chassis. Single turbo RB20DET engine. Lighter than the GT-R.

• R32 GT-R: Based on the BNR32 chassis. AWD with ATTESA E-TS and powered by the twin-turbo RB26DETT. Wider track, aluminum fenders, upgraded brakes, and multi-link suspension.

• R33 GTS25t (1993–1998): Rear-wheel-drive with the RB25DET engine. Still sporty, but not in GT-R territory.

• R33 GT-R: BNR33 chassis, ATTESA E-TS Pro with active LSD in the V·Spec variant. Wider body, better weight balance, and active aero systems.

• R34 25GT Turbo (1998–2002): The RWD RB25DET Neo-powered coupe, often mistaken as a GT-R due to visual similarities.

• R34 GT-R: BNR34 chassis, RB26DETT, ATTESA E-TS Pro, Brembo brakes, multi-function display (MFD), and unique aero parts

🔧 Engine & Drivetrain

Model	Engine	Drivetrain	Power
GTS-t (R32)	RB20DET	RWD	~212 hp
GT-R (R32)	RB26DETT	AWD	~276 hp
GTS25t (R33)	RB25DET	RWD	~247 hp
GT-R (R33)	RB26DETT	AWD	~276 hp
25GT Turbo (R34)	RB25DET Neo	RWD	~276 hp
GT-R (R34)	RB26DETT	AWD	~276 hp

Note: All GT-R models used the stronger 5-speed or Getrag 6-speed transmissions, while GTS-t and 25GT variants used 5-speed manuals or autos.

🔍 Key Differences

• AWD vs RWD: GT-Rs have Nissan’s ATTESA all-wheel-drive, critical for traction and high-speed stability.

• Body and Aero: GT-Rs feature wider body panels, front diffusers(R34), rear diffusers (R34), and enhanced cooling.

• Brakes: GT-Rs came with larger brakes (often Brembo), while GTS models used more basic setups.

• Interiors: GT-R interiors have unique steering wheels, seats, and in the R34, a multi-function display showing engine vitals.

⚖️ Weight and Balance

• GT-R models are heavier due to AWD systems, but feature better balance and structural reinforcements.

• R33 GT-R in particular focused on improved weight distribution over the R32.

🔧 Tuning Potential

• RB26DETT is overbuilt and responds well to boost, supporting over 500 hp with the right mods.

• RB25DET engines are strong, especially the NEO version, but lack the same level of aftermarket support and durability as the RB26 under extreme use.

Summary:

If you want the iconic, track-ready AWD monster, the GT-R is the clear choice. If you’re looking for a lighter, more affordable Skyline with plenty of potential, the GTS-t or 25GT Turbo can offer real fun—but they’re not the same under the skin.
