The Mazda B2600 is a compact pickup truck produced from 1985 through 1993, sold under Mazda's own name and also rebadged as the Ford Courier (and later Ford Ranger in some international markets) due to Ford's partnership with Mazda during this period. The B2600 designation refers to the 2.6-liter engine- but which 2.6-liter engine depends entirely on the model year.
From 1986 to 1988, the B2600 used a Mitsubishi-sourced G54B engine. In 1989, Mazda replaced it with their own G6 engine- a completely new design that shares only its approximate displacement with the G54B. The G6 uses a different bore and stroke (92mm x 98mm vs the G54B's 91.1mm x 98mm), different block architecture, and Mazda's own twin-balance-shaft design. In North American specification the G6 produces 121 hp and 149 lb-ft of torque- a solid output for a naturally aspirated 2.6-liter four-cylinder of the era.
The B2600i (fuel-injected version) with the G6 engine is the most practical used replacement candidate. Parts support for the G6- while not as widespread as Japanese domestic market Mazda engines- is available through Mazda specialists and the dedicated B-series truck community.
Two completely different 2.6-liter engines were used across the B2600 production run:
| Engine | Years in B2600 | HP | Notes |
|---|---|---|---|
| G54B (Mitsubishi) | 1986 to 1988 | 109 hp | Mitsubishi-licensed engine. 2,555 cc. Different bore/stroke from G6. Also found in Mitsubishi trucks and vans of the era. |
| G6 (Mazda) | 1989 to 1993 | 121 hp (North America) | Mazda-designed engine. 2,606 cc. 92mm bore x 98mm stroke. Twin balance shafts. Unique to Mazda B-series trucks. |
| INCLUDED- Long Block | Block, crankshaft, pistons, connecting rods, camshaft, cylinder head, valve train, balance shaft assembly, oil pan, and timing cover. |
|---|---|
| NOT INCLUDED | Intake manifold, fuel injection system or carburetor, exhaust manifold, distributor and ignition, alternator, power steering pump, starter, flywheel, accessory brackets. |
| Core Note | No core charge. You are not required to return your old engine. |
The Mazda G6 engine was factory installed in the following vehicles (1989 to 1993 only):
| Mazda B2600i Pickup (1989 to 1993) | 2WD and 4WD- G6 engine with EFI |
|---|---|
| Mazda MPV (1989 to 1994) | Some MPV applications also used the G6 engine |
| Ford Courier (some markets) | Ford-badged versions of the B2600 in select international markets |
The G6 uses Mazda B-series truck motor mount locations and bellhousing pattern. It is a direct replacement for any 1989 to 1993 B2600i. For 1986 to 1988 B2600 trucks with the G54B, the G6 is NOT a direct bolt-in and requires motor mount and accessory adaptation.

Used OEM vs Rebuilt- Which Is Right for You?
Used OEM is the right choice for a B2600i replacement- particularly where a compression-tested documented G6 unit is needed. Given the limited rebuilder network for the G6, a tested used OEM unit is often more practical than a rebuild.
A specialist rebuild makes sense if you need fresh tolerances or plan to modify the engine. Some Mazda B-series specialists do rebuild G6 engines. Call us and we can advise on current unit condition and whether a rebuild is more appropriate for your needs.
Mileage varies by unit. Where available we provide it. Where it cannot be confirmed, we disclose this before your order is placed.

Needed a G6 engine for my B2600i. Vaz confirmed it was the 1989-and-newer G6 before shipping- not the earlier G54B- which was exactly the question I was worried about. Compression came back 168 to 174 across all 4. Engine is in and running strong. Best used engine purchase experience I have had.
Found a G6 for my B2600i here after searching for weeks. Vaz confirmed the EFI version which matches my truck's setup. Compression was good across all 4. One distributor o-ring was seeping- they caught it during inspection and disclosed it before I bought. Fixed for $6 at install. Good honest seller for a hard-to-find engine.
