Samsonas Sequential 6 Speed GTR

The Samsonas 6-Speed Sequential Gearbox is a high-performance, motorsport-grade transmission designed specifically for the Nissan Skyline GT-R (R32, R33, and R34) models.

This full sequential kit features a robust solid aluminum case and is engineered to handle extreme power demands in drift, drag, rally, and circuit racing.

Key Specifications and Features
According to manufacturer and retailer data from Samsonas Motorsport and CBS Racing Shop, the gearbox includes:

Torque Capacity: Rated to handle up to 1,400 Nm (~1,032 lb-ft), depending on the specific options selected.

Weight: The unit has a dry weight of approximately 38 kg (84 lbs).

Internal Construction: Utilizes straight-cut teeth for minimum rolling resistance and a 5-dog engagement design for lightning-fast gear changes.

Materials: Features a special steel X300 clutch shaft and internals that are shot-peened and super-finished for maximum durability.

Versatility: While designed for the GT-R’s 4WD system, it includes a transfer or reduction gear and offers over 400 different ratio options.

Performance and Integration
Expert shops like Maptec emphasize that this gearbox is flanged to the original housing, maintaining a cleaner installation.

Upshifting: To maximize the sequential design, reviewers recommend using a programmable ECU (such as MoTeC or Link ECU) to enable full-throttle upshifts without using the clutch.

Customization: Bellhousings and clutch shafts can be ordered on demand to fit specific car configurations, though these often incur extra costs.

Lead Times: Due to high demand, retailers like The Skyline Shed have noted manufacturing lead times can be approximately 3–4 months
