A Mazda MX-5 On Steroids: Australia’s V8 Engined Bullet Roadster

In the late ‘90s, Australian John Bettini unleashed onto the word the Bullet Roadster. What begin life as a heavily modified Mazda MX-5 with an RX-7 13B powerplant gradually evolved into a V8-engined monster like the one you see here that we found for sale in Queensland, Australia.

According to the seller, this was the fifth Bullet Roadster built and the first V8-engined one to roll out of the company’s then new Chinderah, NSW factory. It’s all hearsay, of course, but I’m willing to believe the words of a 62yo motoring enthusiast with arthritic knees. So here goes...

Bullet No. 5 was a special order from a man named George Covacic who supplied a 4.6-liter all-alloy, fuel injected V8 crate motor along with a Tremac 5-speed manual transmission and the differential from a Holden Commodore SS. Like all Bullet supercars, the brakes and suspension came from the Mazda RX-7.

Yes Please: Porsche 911 with GM LS1 V8 Power [Videos]

By taking a kitbashed GM-sourced LS1 V8 engine and slotting it into an AWD Porsche 996, LS1tech forum member “1dirtyZ” has set out to create something truly unique. Sure, it’s unconventional and perhaps a little sacrilegious...but just look at the Porsche donor car.

It’s a wreck, the victim of a catastrophic engine fire. It has a ruined interior and a body that’s been damaged both by fire and rust. It would have spent the rest its days rotting away in a car wreckers yard if 1dirtyZ had not rescued it.

And even though this confabulation of All-American grunt and German precision engineering is not yet finished (it doesn’t have a rear bumper, for one), it certainly runs and can even be driven around a dirt race track. You can check out our gallery of in-progress images below and a handful of videos showing the V8-powered Porsche 911 running.

Pontiac Solstice gets an Engine Transplant from a Toyota Supra

In the world of engine swaps, anything goes but it’s always nice to see people experimenting with different kind of builds. For Car Lounge forum member ‘Phlow’, the patient was a Pontiac Solstice roadster with a weak heart - or so to say.

While most physicians would prescribe a local LS V8 transplant, this doctor went for something more exotic, to be precise a 2JZ, which is a code name for the Toyota Supra’s twin-turbocharged inline-six.

Insane! Swedes Turn a Dodge Viper into the Saab 9-3 SRT10 MegaPower

Proving once again that there is no limit to what one can build when you let your imagination take over, a team of Swedes transformed a Dodge Viper into the menacing Saab 9-3 SRT10 MegaPower you see in these pictures.

It all started when a man bought a wrecked Dodge Viper SRT-10 with the intention of rebuilding it. However, it soon became obvious that task was far more difficult than he originally thought due to the extent of the damages and the lack of parts. It didn’t take long to come up with a fresh idea: strip the Viper’s body clean and use the mechanical hardware and parts of the chassis on a Saab 9-3 Sport Combi.

eBay Sleeper: 1979 Chevrolet Malibu with Pontiac GTO 5.7-liter LS1 V8

Now that Pontiac is officially gone, one way of keeping the heritage alive is to salvage whatever parts you can find. We don’t know if that’s what the owner of this 1979 Chevrolet Malibu thought, but, nevertheless, he did swap the original engine with a modern 5.7-liter LS1 V8, sourced from a wrecked GTO, while keeping the styling of the car pretty much stock.

1985 BMW 557i with Corvette V8 Heart Transplant

Owning a mint condition E28 BMW 5 Series would be a dream come true for most bimmer fans. However, the owner of this Euro-spec 1985 528i was probably not impressed by the stock 2.8-liter powerplant’s 184-ponies, so he performed an engine swap.

If it was up to me and money wasn't an object, I would've probably tried to fit a V12, but the 1999 Chevy LS1 V8 isn’t a bad fit either - that is, if you really feel the need to hear an American V8 burbling under the hood of a vintage German sedan.

Video: Dacia Logan with Volkswagen 2.8-liter VR6 Engine!

I don’t know if the word Dacia gives James May that fizzing sensation he often talks about, but the Top Gear host seems pretty fond of the Romanian brand. Same goes for low-budget European buyers who see the Renault-era Dacias as well priced models with affordable maintenance costs. One of the Romanian firm's latest cars, the Duster was even nominated for the 2011 COTY award.

However, the brand's models aren't exactly exciting, even more so when it comes to sheer performance with their mundane, small displacement petrol and diesel engines. But as always, for every problem there's a fix. This man's answer was to ditch the Logan sedan's four-cylinder and throw in a 2.8-liter VR6 Volkswagen engine.
