Just the other day when I had my new throttlebody installed the mechnics are goodyear asked me about the engine and that it looked awfully familiar to them!
From the other car:

and

vs from the MINI

Its been a long known fact that the motor from the neon and from the mini are the same, but the size is different, mini 1.6 - dodge 2.0 but they will not interchange as they look that they might do,i alrady have done research on this in hopes of finding a way for more cc, headgaskets do not match cylinder are much closer together in the mini,... the design was a joint venture between chrysler and bmw that started in 1998, the motors are both built out of brazil, but there are differences, and some similarities, you can use a "neon" ignition by msd or some other aftermarket, but it appears to stop there.... or i havent found it yet....

DING DING DING-
Correct and still champion!!!
Yep, those mechanics were interested in my MCS engine alright. What a treat putting in my throttlebody! At first they were confused. Why would anyone want to put in a throttlebody-they uttered. Then I told them it was a custom machined modified TB- so they said they would look at it when they had time. Not much later they had it installed. I guess they needed a break from the mundane jobs and wanted to play around for a change of pace. They did do a good job.

unless you were in Europe, that is not the MINI engine. See this thread for more info on the manufacturer of the MINI engine.

Thanks this thread leads to an Ward's Autoworld article about the 10 best engines and this description of the MINI:
see http://waw.wardsauto.com/ar/auto_best_engines_6/

MINI 1.6L I-4
Engine type: 1.6L supercharged SOHC I-4
Displacement (cc): 1,598
Block/head material: cast iron/aluminum
Bore ¥ stroke (mm): 77 ¥ 85.9
Horsepower (SAE net): 163 @ 6,000 rpm
Torque: 155 lb.-ft. (210 Nm) @ 4,000 rpm
Specific output: 102 hp/L
Compression ratio: 8.3:1
Application tested: Mini Cooper S

After the way some of the European press disparaged the all-new Mini Cooper's naturally aspirated “Pentagon” 1.6L SOHC I-4 — the spawn of the now-controversial joint venture between DaimlerChrysler AG and BMW AG (Mini's owner) — we didn't expect much from the supercharged variant.

After all, there are all sorts of 4-cyl. engines making 160 hp without the help of a supercharger.

Yow, were we wrong. Whatever the supposed deficiencies of the naturally aspirated Pentagon (we suspect most critics believe they don't need to look any deeper than the scrawny 115 hp listed in the press kit), the Eaton Corp. supercharger apparently camouflages, because almost every Best Engines judge proclaimed this engine a genuine hoot to drive.

The supercharger delivers a modest 11.6 psi (0.8 bar), and from a standstill, not much happens for the first 50 ft. (15 m). But once past that anxious moment it takes to hit about 2,500, the engine finds the cam, the supercharger begins earnest compression and the Cooper S launches to 60 mph (97 km/h) in a coltish 7 seconds.

Once on the move, the supercharged Pentagon uses the plump 155 lb.-ft. (210 Nm) of torque to good effect, and the standard 6-speed manual is a willing accomplice. The Cooper S is quite lively in cut-and-thrust driving. Our complaints are minor: There is “lag,” despite superchargers' supposed eradication of that foible more closely associated with turbochargers. And the by-wire throttle is not what we'd call micrometer-precise; it's much more an on/off switch than a rheostat.

As expected for a small-displacement engine using forced induction, most of the critical internals have been suitably bulked-up to handle the extra pressure. The pistons, crankshaft, valves and cooling system all are upgraded, yet one source claims this supercharged 1.6L 4-cyl. is “the least-expensive boosted engine ever made.”

Fine with us — it helps BMW price the Mini Cooper S at a manageable $19,975, and fun-to-drive-per-dollar certainly is a chief calling card with this engine.

Chrysler engineers were responsible for designing and developing the 1.6L Pentagon I-4, and it's built at the DC/BMW Tritec joint-venture plant in Campo Largo, Brazil. Almost from the first test-drives of the normally aspirated Pentagon (the only version of the Pentagon available when the Mini launched), it's been a point of contention, with critics saying the normally aspirated variant is low on power and even lower on refinement.

The supercharged Pentagon suppresses those catcalls by being responsive, pleasing to the ear (the blower's subdued whine is a pleasant confirmation that you've got something extra) and genuinely entertaining to drive. The “pop” of a supercharger definitely makes all the difference here — we love this mouse's 102 hp/L roar.
