⚙️ Engine Specifications

Primary Engine:

2.0L KL-DE DOHC V6 (Naturally Aspirated) and 2.5L KL-ZE DOHC V6 (Naturally Aspirated) were common in MX-6. For the GT-R Turbo variant, it's highly likely referring to the F2T (FE3) or a closely related turbocharged 2.0L four-cylinder engine or potentially the JDM specific 2.5L V6 with turbocharging. Given the 'GT-R Turbo' moniker, it strongly suggests a performance-oriented turbocharged engine. A probable candidate is a modified FE3 or a variant of Mazda's BP-T engine. However, for the specified years, the most commonly associated performance engine was the 2.0L FE3 Turbo, derived from the Capella/626. Need to verify exact engine code for the GT-R Turbo trim.

Estimated Horsepower:

Approximately 190-210 hp (for factory turbocharged variants, exact figures depend on specific engine code and market).

Estimated Torque:

Approximately 200-220 lb-ft (for factory turbocharged variants).

Fuel System:

Electronic Fuel Injection (EFI) with Turbocharger and Intercooler.

Engine Codes:

FE3 (Turbocharged 2.0L I4) is a strong possibility for the GT-R Turbo variant, though specific market variations might exist.

Engine Type:

Inline 4-Cylinder, Turbocharged, DOHC.

Displacement:

2.0 Liters (1998 cc) for the FE3 engine.

Turbocharger Details:

Likely a Garrett or IHI turbocharger, with an air-to-air intercooler. Manual provides detailed inspection, repair, and performance testing procedures.

Ignition System Type:

Electronic Ignition System with Distributor (likely distributorless ignition on later models). Manual details coil pack testing, sensor diagnostics, and timing adjustments.

Cooling System Capacity:

Approx. 8-9 liters (8-10 quarts) for the 2.0L engine. Manual will specify exact capacity.

🔧 Transmission

Standard Transmission:

5-Speed Manual Transmission.

Optional Transmission:

4-Speed Automatic Transmission.
