Long before Audi took over, Lamborghini decided to gift the world with the Jalpa, only building around 450 units of the mid-engined machine. Well, one of those cars has gone full aftermarket and is now ready to take on any brand-new Lambo.
We're talking about a barn build here, but one that comes with impressive specs. The center of this 1988 Raging Bull is now occupied by an LS1 engine with a 383 ci stroker kit. While the Jalpa initially received a supercharger, the result didn't seem to go well with the custom-built transaxle gearbox, which is based on Toyota Camry bits.

As a result, the blower was scrapped in favor of twin Garrett turbochargers that come from a Ford XR6 (yep, this is an Aussie build). Using what is described as a "moderate" boost level (make that 14.5 psi), the V8 delivers 690 hp at the rear wheels, with the setup using 98-octane pump juice.

While that's quite a jump from the 250 hp factory output of the Jalpa, things won't stop here. But before the owner decides to dial up the boost, we're inviting you to check out the first drag strip session of the Lamborghini.

Okay, but what about the performance? How far have things gone?

For now, the GM-engined Lamborghini Jalpa has managed to pull a 9.7s quarter mile, which makes it considerably faster than any Lamborghini currently on sale, Superveloce or not. And with that exposed TT setup, which reminds us of Porsche 911 Turbo builds, this Jalpa won't lose anything in the looks department, either. As for the soundtrack of the badass machine, we'll let you be the judge of that after you hit the "play" button below.

P.S.: Yes, we know, this supercar could use a new wiper setup, but that's a common issue with Lambos of its age.
