THUNDERMINGO 2-Barrel Carburetor for Toyota 22R (TOY-505) – Round Plug, Electric Choke

This precision-built carburetor is engineered to replace worn or damaged original units on classic Toyota pickups with the 22R 2366cc L4 engine. Constructed from heavy-duty zinc alloy and assembled with tested internal parts, the unit mirrors factory bore sizes and mounting geometry so you can restore drivability without major modifications. It’s designed for models that use the round green electrical connector—commonly found on 1981–1986 vehicles and early 1987 builds—so confirm your plug style before installing.

Will this carburetor physically fit my Toyota 22R engine?

Yes, the THUNDERMINGO TOY-505 is built to the same external dimensions and mounting centers as many original 22R two-barrel carburetors. Bolt-hole spacing and choke housing dimensions match common factory specs, letting you swap units without adapter plates. Still, verify the connector type and bore sizes before purchase.

• Bolt hole spacing: 96.9 x 50 mm (center-to-center)
• Air inlet bore: 40/32 mm (1.57/1.26 in)
• Venturi diameters: 40 mm and 26 mm
• Choke housing: 94 x 78 mm external, 76.5 x 40 mm inner

Which model years and carb connector types are compatible?

This carburetor matches Toyota pickups running the 22R engine with the round green wiring plug—standard on 1981 through 1986 and the first half of 1987. It does not fit later models that use the square-end connector introduced on late-1987 through 1990 units. Check the plug shape on your current carburetor before ordering to avoid mismatch.

• Compatible: Toyota Pickup Base, DLX, SR5 (1983–1987) manual
• Compatible: Turbo variants where listed (1985–1987 manual)
• Compatible: 2-barrel 22R with round plug (1981–1986; early 1987)
• Not compatible: 22R carburetors with square-end connector (late 1987–1990)

What are the construction and electrical details I should know?

The body is cast from heavy-duty zinc alloy for durability and heat resistance, and the choke is an electric/automatic type operating at 12V DC. Internal assemblies are factory-oriented to ensure consistent fuel metering and predictable behavior across warm-up and steady-state conditions. Wiring uses the round green connector pattern used by original TOY-505 units.

• Material: heavy-duty zinc alloy
• Choke: electric/automatic, 12V DC input
• Precision-tested internal components for reliable assembly
• Factory-style round green plug (TOY-505 compatibility)

How straightforward is installation and what should I check first?

Installation is typically a direct bolt-on replacement if your intake and linkage match the original layout. Before installing, confirm the wiring plug shape, throttle linkage orientation, and vacuum line routing. Replace gaskets and clean mating surfaces for a leak-free seal and reliable operation.

• Confirm round green electrical connector on existing carburetor
• Replace intake manifold gasket during swap
• Inspect throttle and choke linkages for alignment
• Test for vacuum leaks after installation

Who this is for: This THUNDERMINGO replacement is intended for owners, restorers, and mechanics working on Toyota pickups and SR5 models with the 22R 2.4L (2366cc) manual transmissions from 1981 through early 1987 that require a two-barrel carburetor with a round plug connector. If your vehicle uses the later square-end connector or a different bore configuration, consult fitment details or seek the correct TOY-507-style unit instead. The product suits those wanting a factory-dimension replacement built from durable materials and prepared for direct installation when the connector and manifold match.
