In mathematics and physics, a vector is described as being a quantity having both direction and magnitude. Yesterday, the Vector M12 went in the direction of Crack Pipe with a marginal 55% magnitude, despite heavy lobbying as to its demerits. That car was interesting in that it was a nominally American car, with a foreign motor appended. More traditionally, sturdy, large-bore 'Merican motors have found their way under the hoods of European sports cars, hoonerizing their performance. And that's the case with today's candidate - although, while its badge marks it as needing a work visa, it too was built in the U.S.!

When BMW debuted the Z3 in 1996, it underwhelmed with the standard fitment of an anemic 138-bhp 1.9-litre four cylinder. An answer to the success of the Mazda Miata - and the first new car built at BMW's South Carolina plant - it also took heat for its bean-counteritis which resulted in a plastic rear window, low-grade interior and E30-based trailing arm rear suspension.

Today's '97 Z3 hasn't had anything done to fix the suspension or cheapness problems, but the issue with the underpowered engine has been rectified- that four-banger has been deep-sixed and replaced by a Chevy small block. As that alone would be insufficiently extroverted, the builder has added the automotive equivalent of whipped cream with a cherry on top by bolting on a roots-type blower that punches through the hood like a baby alien through the chest of an unwitting German spacefarer. That way, not only will you be known by your skid marks (and not the kind that made 8th grade gym class such torture), but also by the high-pitched din that can only be derived through the application of mechanical forced induction. Like Lawn Darts and roosters, this would be a purchase both you and your neighbors could enjoy- especially at 3 AM.

Backing up this torque monster is a T10 4-speed so those of you who are three-pedal adverse will just have to keep walking as there's nothing to see here. After that, there's not much detail about further drivetrain modifications, and if it's still rocking the stock Z3 pumpkin and half-shafts, you'd best set up a tab at Driveshaft Depot as you'll be twisting those buggers into pretzels on a regular basis.

The Z3's clamshell bonnet appears massive when opened, but it's still surprising to find that the small-block eight fits under it. The pictures demonstrate that it does, but it's so tight a fit against the firewall that it looks like you might pop a spark plug wire off if you turn on the wipers. The rest of the car is standard 12-year old Z3 with typical of wear and tear and the need for a few cans of Krylon, so figure adding to that $20,000 asking price to make the purchase less contradictory in your driveway.

But what would you do with this if it were in your driveway? It's too crazy for Boys Town, and too much of a boy for Crazy Town. Other BMW owners would shun you, Hot Rodders would take one look at the effete little car and would make that threw up in my mouth a little bit head bob. You'd be a social outcast among either group, doomed to brodie by yourself- your parking lot donuts solitary endeavors shared only with the light-pole perched pigeons. How sad would that be?

But so what? Eff them, and eff the pigeons too, you're a lone wolf and you've got that blower to keep you company while enjoying its Mad Max cacophony every time you push the loud pedal. Who cares if it blocks your view of cross-walking pedestrians when you make right turns? If they want to live forever they should stay on their own block.

Despite being the object of their owner's derision, you'll get the satisfaction of blowing the doors off of the other Z3s, provided you stay out of the twisties. And who doesn't love that precision-cut hood opening allowing for the blower to stick through and requiring solid engine mounts to keep it from flinging the hood into the passing lane the first time you gas it? You'll get all that as well as the ability to toss a BMW key fob on the bar, eliciting a raised eyebrow of interest from status-seeking clubbers. Once you get them into the car, its over the top demeanor and your spot-on impression of Kurt Russell's Death Proof character will mean they'll never trust a key fob again. Eff them too.

So, it's a rebel and it'll never, never change. And it's that indifference to traditional boundaries that gives this car its appeal. But, that being said, would you drop twenty large to wrinkle the asphalt in this blown bimmer? Or, for that amount, is this a heart transplant you hope the body rejects?

You decide!

Parts are so plentiful that a good case can be made for the use of a 350 in your post-apocalyptic cruiser, simply because you could pull up to any smoking GM wreck and probably find a replacement water pump. And cheap too. Here's a brand new example found on eBay which puts out some strong power and only rings the 'buy it now' bell for $2,195. How can you go wrong?

We're going to let the owner do all the talking here, while we just sit back in admiration:

1979 Fiat X/19

400 C.I. small block Chevy. Tornado transaxle all metal body engine in rear. 400 + horsepower. Lot of goodies, electric exhaust dumps.

Does idle rough, big camshaft. No power steering or power brakes.

Is streetable, but is an eye catcher sitting still.

Killer dash, dude.

In Junkman's own words: "It's all steel, crazy fast, surprisingly good handling and totally offensive to all Porsche purists." Hooray for offending the purists!


Look, no duct tape, hose clamps, or plywood! Hmm... there must be room for a supercharger in there somewhere...


In addition to doing very clean engine swaps, Junkman is no slouch in the photography department as well. Oh yeah, and this isn't his only European steed with a Detroit heart transplant: "We also have a '62 Deutsch-Bonnet LeMans Spyder which has had its original 2 cylinder, 850cc engine replaced with a Pontiac 400 V8 (possibly out of another LeMans...)" Keep up the good work, Junkman!
