This 1992 Toyota MR2 Swapped in a Turbo Honda K20A and a Six-Speed, and It's Live on Cars & Bids

This 1992 Toyota MR2 no longer has a Toyota engine, and the listing says so up front. According to the seller's listing on Cars & Bids, the original 5S-FE four-cylinder and five-speed have been replaced by a 2.0-liter K20A and six-speed manual from an Acura RSX Type-S, with a Precision Turbo 6266 bolted on and a FuelTech ECU tuned for E85. The auction is live and ends Friday, November 13, at 3:06 p.m. ET. At the time of writing the high bid was $3,456 after five bids.

Why a Honda K-Series Belongs in an SW20

The second-generation MR2 arrived for 1991 with a mid-mounted, transversely oriented engine, and that layout is a big part of why Honda K-series swaps into the car have become an established niche. The practice is common enough that the aftermarket has dedicated mounts and headers for it, and enthusiasts have a nickname for the result: a "Toyonda." This example leans fully into the idea. The seller's list includes a Toyonda turbo manifold and Toyonda polyurethane engine and transmission mounts, so the swap is built around parts made for exactly this combination rather than improvised brackets.

The K20A itself came from an Acura RSX Type-S and reportedly has about 87,000 miles on it. Power goes to the rear wheels through the RSX Type-S six-speed, which has been upgraded with 1-4 GearX gearing, an InLine Racing lockout shifter, an MFactory limited-slip differential, an Action Clutch twin-disc clutch with ARP hardware, and a 4.7 final drive ratio. Driveshaft Shop Pro Series axles and hubs with ARP studs round out the driveline.

The Turbo and Fuel System

Boost comes from a Precision Turbo 6266, a sizable unit for a 2.0-liter engine, managed by a Turbosmart HyperGate 45 external wastegate and a Turbosmart RacePort blow-off valve. A SpeedFactory Racing backdoor intercooler handles charge cooling. The intake side uses a Pracworks carbon fiber and billet intake with a Skunk2 76mm throttle body, while the engine wears an ATI Racing Super Damper, a Skunk2 billet timing cover, and a Mechman 240V alternator.

Fueling is where the build gets more serious than a typical weekend swap. A FuelTech FT550 ECU tuned for E85 runs Fuel Injector Clinic 1650 injectors, dual Walbro Hellcat pumps, a DeatschWerks lift pump and regulator, and a Nuke Performance sumped fuel cell, all connected with PTFE lines. A tucked wiring harness and a shaved, painted engine bay suggest the owner cared about presentation as well as output. The listing does not provide a dyno figure, so there is no documented horsepower number to quote.

Chassis, Wheels and Cabin

Suspension changes are straightforward: BC Racing coilovers, Hux Racing Pro Series rear control arms, and TRD sway bars. The wheels are Weld Racing beadlocks, 17 inches in front and 15 inches in the rear, with Mickey Thompson 275/50 Street SS drag tires out back, which tells you what this MR2 was set up to do. Inside are Recaro DC5 seats, a Nardi steering wheel, and a Fulcrum Design FuelTech instrument cluster. The battery has been relocated behind the passenger seat, and the car has MR2 Heaven Kouki taillights and an aftermarket front lip.

What the Seller Discloses

This is a project-grade car, and the listing is candid about it. The MR2 has no odometer, so it is listed as True Mileage Unknown. The fuel gauge is missing, and the seller reports that the ignition intermittently fails to shut the engine off. Other disclosed issues include a cracked windshield, a cracked front lip, chipped and faded paint, repainted body panels, and worn seats. The tires carry 2021 date codes. The seller says the timing belt, head studs, head gasket, and oil pump were replaced, but no documentation was provided to verify that work. They bought the car in August 2026 and have added roughly 50 miles since. The title is clean in Wyoming, and Cars & Bids notes that the modifications may prevent the car from passing emissions testing in some states, so buyers should confirm registration requirements before bidding.

Keep in mind that nearly everything about the build is seller-reported. Cars & Bids says the information comes from the seller and that bidders are responsible for verifying it, and the listing includes start-up, idle, and drive-by videos to help with that.

The Bottom Line

A turbocharged K20A in a mid-engine Toyota is the kind of swap people argue about and then end up admiring, and this one is built with recognizable, purpose-made parts instead of guesswork. It is also rough around the edges and unfinished in places, which is reflected in a bid that is still very low. For someone with a K-series shopping list and tolerance for a missing odometer, it could be a rewarding project. If swaps like this appeal to you, we have also covered an 850Ci that traded its automatic for an E46 M3 six-speed, a twin-turbo 2JZ Toyota Aristo, and a Porsche 914 with a 911SC flat-six.
