This 1987 Pontiac Firefly is powered by a fuel-injected Chevrolet 350ci V8 backed by a TH350 automatic transmission. The seller, a high-school shop teacher, acquired the car nine years ago in a non-running state and performed the drivetrain swap, suspension work, and more. The car features a roll cage, S10 spindles and brakes, frame additions constructed from 2×3″ steel tubing, and a number of custom-fabricated components as described in the listing. This V8-powered Firefly is offered by the seller with British Columbia registration.

The Firefly Turbo was a Canadian-market derivative of the Suzuki Swift, and this example is finished in red. The seller notes that the body appears to have been previously repainted, and peeling paint is present. The seller repainted the driver-side rear quarter panel when the fuel filler was relocated from forward of the rear wheel arch to aft. Rust is noted on both doors and the hatch, and the seller has replaced the rocker panels.

A walk-around and engineering walk-through video is viewable above, and a build thread can be viewed here. The battery has been relocated to the rear of the car in a ventilated box, with a remote battery cutoff switch handle routed through a hole in the passenger-side taillight.

The cabin is trimmed in gray with a roll cage, door bars, and fixed bucket seats. The seller notes that the seats are mounted in a fixed position and show wear and holes in the fabric. The car is fitted with a defroster but is not equipped with a radio, fresh-air inlet, sun visors, or working dome light.

Neither a neutral/park safety switch nor a reverse light switch are present, though the wiring for both remain. The tachometer was sourced from a Firebird but is not functional. Approximately 264k kilometers (~164k miles) are shown on the odometer.

Power is provided by a 3970010-casting 350ci Chevrolet V8 with ported 882 cylinder heads. Modifications include a Lunati 256/262 camshaft, Holley big-bore TBI unit, externally adjustable fuel-pressure regulator, and a reprogrammed factory TBI ECU with Moates chip. The new items reportedly have been spliced into the Firefly’s wiring harness.

A cold-start video is viewable above. The seller notes the fuel-injection programming requires fine-tuning. The Moates chip coder and seller-generated tunes are included with the car. The fluids and brakes reportedly have less than 3k kilometers on them, and the oil was recently changed.

The 2×3″ tubular steel frame additions are viewable in gallery photos. Power is sent to the rear wheels via a TH350 automatic transmission with a dual-fed internal direct clutch, hardened intermediate sprag, and drilled separator plate. The rear axle was sourced from a 1988 Firebird and has been narrowed 9″ and fitted with a Detroit TrueTrac differential and 2.73:1 gears. The seller notes a driveline vibration at speed, which is believed to be caused by the pinion angle.

The rear axle is suspended with a 4-link setup with polyurethane bushings, and a set of spherical rod ends is included. An autocross video is viewable above.
