Datsun 240Z 1971 – Chevy-Powered

A rusted 1971 Datsun 240Z shouldn’t have any business running a Chevy 4.3L V6, let alone breathing through a turbocharger stolen off a Ford Power Stroke diesel. But that’s exactly what somebody built, mixing three brands and three engineering eras under one hood. The pairing isn’t as random as it sounds — diesel turbos are built for exactly the kind of low-RPM torque a small V6 needs. It’s the kind of mutt build that gets talked about at every cruise-in.

These guys are crazy! A rusted 1971 Datsun 240Z with a Chevy 4.3L V6 and a turbo from a Ford Power Stroke Diesel!?

You don’t expect a Japanese sports car to show up on a muscle car page, and honestly, this one earns its spot for being about as unhinged as builds get. Underneath a body that’s more patina than paint sits a Chevy 4.3L V6 — already a strange choice for a 240Z — but the real kicker is what’s feeding it boost: a turbocharger pulled straight off a Ford 7.3L Power Stroke diesel. Three different manufacturers, three completely different eras of engineering, all bolted into one rust-bucket Z-car. So does this thing actually run, or is it just a shop-floor curiosity waiting for someone to finish the job?

Why a Diesel Turbo on a Gas V6 Actually Makes Sense

Power Stroke turbos are built to move huge volumes of air at low RPM to handle a diesel’s torque curve, and swappers have found they spool differently than a typical gas-engine turbo — a good match for a torquey small-displacement V6 like the 4.3L, which is essentially a small-block Chevy V8 with two cylinders lopped off. It’s the kind of junkyard engineering that separates a real hot rodder from someone just bolting on parts because they’re cheap.

The Build Everyone Points To

This style of swap echoes a well-known example in the Z-car world: the Chevy V6-and-Power-Stroke-turbo 240Z that the Roadkill crew built and raced, reportedly making around 387 horsepower and 430 lb-ft at the wheels — respectable numbers for a car that started life as a lightweight Japanese sports coupe never meant to see a turbo of any kind, let alone a diesel one.

Brand Loyalty Doesn’t Build Horsepower

Whether this particular rusted 240Z reaches those numbers or stays a driveway project, it’s proof the swap community doesn’t care about brand loyalty — they care about what’s cheap, available, and makes power. A Chevy heart and a Ford lung in a Datsun body is exactly the kind of mutt build that gets talked about at every cruise-in for years.

The Z-Car That Started It All

The 240Z that debuted for the 1970 model year was Nissan’s play at the same market BMW and Jaguar had been chasing with their own sports coupes, except Datsun undercut them on price by a wide margin. Power came from a 2.4-liter SOHC inline-six, the L24, driving through either a four-speed or five-speed manual, wrapped in a body styled with input from Yutaka Katayama, the executive credited with pushing the car into the American market in the first place. It sold well enough to make Datsun a household name in the U.S. almost overnight, which is exactly why a rust-eaten example with someone else’s drivetrain still draws a crowd.

Why Swappers Love the S30 Chassis

Original 240Z engines are prized today, but the S30 chassis underneath has become one of the most popular swap platforms in the hobby precisely because it’s light, rear-wheel drive, and roomy enough under the hood to accept engines Datsun never dreamed of fitting. Small-block Chevy V8s were the classic swap for decades; the more recent wave of builders reaching for GM’s 4.3-liter V6 or an LS V8 instead reflects how much cheap, reliable American V8 and V6 hardware has flooded salvage yards compared to increasingly scarce factory Z-car parts.

What the Roadkill Crew Proved

The Motortrend-produced Roadkill series has built a reputation on exactly this kind of shop-floor engineering: taking a cheap, often rough donor car and stuffing it with whatever oddball drivetrain combination the hosts can scrounge up and make run. Their Chevy-V6-and-diesel-turbo 240Z build became something of a cult favorite among swap enthusiasts specifically because it proved a mismatched combination of parts, sourced from three different manufacturers, could be made to run reliably rather than just limp around a parking lot for a camera crew.

Turbo Diesel Hardware in a Gasoline Application

Power Stroke turbochargers were engineered to survive the punishing exhaust heat and boost demands of a diesel truck engine, which means they’re often overbuilt relative to what a comparable gas-engine turbo would need to handle similar power levels. That extra headroom is part of the appeal for builders chasing junkyard-sourced boost on a budget: a diesel truck turbo can often be had for a fraction of the price of a purpose-built gasoline performance turbo, even if matching its flow characteristics to a smaller V6 takes some trial and error.

A Body That’s Seen Better Days

A patina-heavy, rusted body doesn’t hurt the appeal of a build like this one to the swap community; if anything, it reinforces the point that this is a driver being built for function over a numbers-matching restoration. Original, rust-free 240Z sheet metal has become increasingly hard to source as the cars age past the half-century mark, which is part of why so many surviving examples on the cheaper end of the market end up as donor cars for exactly this kind of mixed-parts build rather than restoration candidates.

Where a Build Like This Goes From Here

Whether this particular Z ever gets buttoned up and driven regularly or stays a rolling parts experiment, it’s already done its job by giving swap-culture forums something to argue about. Cars built this way rarely chase resale value in the traditional sense; their worth is measured in how much abuse the drivetrain can take and how many double-takes it gets at a cruise night, not in matching numbers or factory-correct trim.

A Reminder of How Far Values Have Diverged

Original, numbers-matching 240Zs in genuinely clean condition have climbed steadily in collector-market value over the past decade, with the best documented examples now trading for figures that would have seemed absurd to the car’s original economy-minded buyers. That climb has actually made rough, rusted donor cars like this one more valuable as swap material than they might have been years ago, since fewer owners are willing to sacrifice a straight, rust-free shell to a wild engine build when a rougher example can do the same job for less money and less guilt. It’s a strange kind of market logic: the healthier the values get for pristine originals, the more the beat-up survivors get funneled toward exactly the kind of mixed-parts experiment this Z represents, because nobody wants to cut into a car that could otherwise be restored to factory spec.
