We love lots of automobiles, that’s no secret, however some automobiles simply hit totally different and SpeedTech Motorsports’  Turbocharged R56 Mini Cooper S is one such automobile. This Mini goes onerous on each degree – it appears so good, it sits so proper, the inside is particular and, as you’d anticipate from an organization with the phrase ‘velocity’ in its title, it’s acquired some critical energy on faucet. R56s actually don’t get significantly better than this.

SpeedTech Motorsports has been round for over 10 years and specialises in VW, Audi, and, after all, Mini. For firm proprietor Abraham Viera, his curiosity in Minis was piqued a few years in the past when he first drove a buyer’s R53 and the remaining, as they are saying, is historical past. When it got here to this R56 construct, there was a really particular motive for selecting this automobile and a transparent plan for the challenge.

“We wished to problem ourselves into making an N14 engine dependable regardless of the popularity it has constructed for itself,” explains Abraham. “We discovered the automobile on-line. The physique was in good situation, however the automobile wasn’t working due to the engine misfiring. Our plan for the automobile from the start was to construct it into the primary N14 engine with a Garrett GTX2867 Gen II turbo on inventory internals and erase the dangerous title it had by giving it this new setup,” he says.

So, whereas this turbocharged R56 Mini is an absolute powerhouse of a Cooper S, there was much more to this construct than simply making a quick Mini and being finished with it.

Unsurprisingly, with the engine not working and in addition being the main focus of this challenge, the 1.6-litre turbocharged N14 four-pot has undergone some critical work, and what SpeedTech has achieved is just superior. “After we acquired the automobile, step one was to repair the misfiring subject it needed to get it working once more,” says Abraham.

“As soon as we had that subject fastened, our constructing challenge started. We knew this was one of many frequent points this engine had and the reason for the engine’s dangerous popularity, and we instantly knew that is the place we needed to begin if we have been hoping to achieve our expectation of giving this engine life once more. That’s why our first modification on the engine was the customized oil catch. This might assist forestall the engine from carbon deposits, which might finally result in one other cylinder misfire,” he says, after which, work started on getting ready the engine for its large improve in energy.

“Subsequent, we put in a customized front-mount intercooler. We did this as a result of we knew that the OEM intercooler wasn’t going to be environment friendly sufficient for the construct we have been attempting to attain. This set up was then adopted by the customized large turbo package.

The staff wished to make use of a Garrett GTX2867 turbo, however we couldn’t adapt it to the unique exhaust manifold. Due to this fact we additionally ended up utilizing a customized exhaust manifold as a result of it might enable us to make use of an exterior wastegate,” explains Abraham. “As a consequence of our selection of turbo, we had to make use of an aftermarket BOV, and for this, we went with the TiAL Q50 as a result of we have been very accustomed to it and had used it on our earlier builds.

“With the massive turbo package, one of many issues we knew we needed to tackle was exhaust restriction and backpressure. We, subsequently, determined to put in a 3” turbo-back exhaust, for optimum circulation. We opted for a 1994 Volkswagen GTI Magnaflow muffler; we now have beforehand used this on our VW GTI construct and favored the best way it sounded, so we determined to maintain that good deep growl with this setup for the Mini,” Abraham says, and whereas it’d sound unconventional, it really works.

“As a result of we had constructed a customized exhaust manifold, it precipitated it to sit down too near the valve cowl, and this might finally trigger it to soften. This required us so as to add a valve cowl warmth protect to guard the valve cowl, and we additionally put in billet caps to keep away from any melting of those sooner or later.

“At this level, our challenge was shifting alongside. We beloved the ability it was producing, however the extra energy the engine made, the extra warmth it produced and the extra gas it required. The methanol and the direct port meth-injection package set up allowed us to deliver down the rising air temperature within the engine,” Abraham tells us.

“Our subsequent step was to regulate the ability it was making on the go. That is once we put in the increase controller, which allowed us to regulate the increase ranges at any time. We then proceeded with switching to colder spark plugs as a result of we knew this improve would forestall future misfires as a result of warmth within the engine. We did the customized tuning after that as a result of we wanted to verify we calibrated the ECU to accommodate the brand new setup since extra air and gas was added,” he says.

“To tie off the brand new engine setup we had up to now, we put in a vacuum distribution block as a result of we wanted extra vacuum sources to make use of the lately put in BOV, wastegate, methanol, increase gauge, and so forth. So as to add extra airflow to the engine we used an RPM consumption manifold as a result of we knew that having larger runners would assist the engine breathe higher.

The staff then put in an uprated increase pipe as a result of we knew that the inventory plastic pipe was not environment friendly sufficient for the quantity of energy we have been pushing. Lastly, we swapped out the common hoses for silicone coolant hoses as a result of this might assist resist the warmth extra,” says Abraham.

That engine spec is simply mind-blowing, the quantity of labor that’s gone into this small four-cylinder is insane, and the tip result’s simply astonishing, with this R56 making a fully epic 402whp, round 460hp on the crank. Not solely that, it’s dependable as supposed, and whereas working at this form of energy degree does require oil modifications each 1500 miles, it’s nearly unbelievably nonetheless working its inventory clutch and flywheel.

With such an epic engine overhaul, you may go away issues there and nonetheless have a next-level R56 construct, however an organization like SpeedTech would by no means contemplate that to be a completed challenge, and with over 400whp on faucet, it stands to motive that chassis upgrades have been required.

“We selected the Forge coilovers, entrance and rear anti-roll bars, entrance and rear anti-roll bar hyperlinks, back and front management arm bushes, a entrance strut brace, and rear Ok-bar,” Abraham tells us, and that’s a suitably complete choice of enhancements.

“The blokes selected these explicit modifications as a result of we wished to have higher stability with the Forge coilovers in addition to have the ability to alter the peak and damping. The anti-roll bars, roll-bar hyperlinks, management arm bushes, strut bar, and Ok-bar have been all finished to have higher stability within the corners,” he explains, and these chassis upgrades guarantee this R56 can deal with the huge quantity of energy that’s being put to the tarmac.

We’ve already touched on our appreciation of this R56’s styling, and, in addition to endowing this Cooper S with otherworldly efficiency, SpeedTech has additionally ensured it appears the half each in and out, and that is one Mini with most presence. “We weren’t searching for only a quick automobile, but in addition a automobile with the smooth look of a present automobile,” smiles Abraham, and that’s precisely what they’ve acquired.

Its entrance finish is enhanced with the addition of a Maxton Design lip with a textured end, there’s a bigger bonnet scoop and Spec D projector headlights, whereas the flanks characteristic Maxton Design aspect blades, and on the rear, there’s an Orranje G-Wing. However that’s not all, as a result of the automobile is roofed in customized additions.

There are the BMW M badges with German flag tricolour stripes, the Mini badges with monochrome BMW roundels within the centres, customized LED Union Jack taillights, plus touches just like the LED entrance and rear aspect markers, plus
the blacked-out aspect repeaters and entrance wing badges.

Then, after all, there are the wheels, and for this construct, SpeedTech opted for a set of staggered 17” gunmetal Rotiform RSEs, and so they look superior. The cross-spoke styling fits the look of the R56 so properly, the gunmetal end is imply and moody, the rears have gotten that candy concave, and the mix of aggressive fitment and the drop from these coilovers will get them filling out the arches to perfection.

Its inside isn’t any much less spectacular, and the aim was to create one thing somewhat extra hardcore. “A smooth look for present was our exterior aim however for the inside, we wished the feel and appear of a race automobile. That’s why we went for our bucket race seats and harnesses,” explains Abraham.

The seats in query are Braum Racing Elite-X seats, and never solely do they give the impression of being good, however in addition they supply a great deal of assist, and so they’ve been paired with matching Braum four-point harnesses on a Braum harness bar. The inventory steering wheel has been changed with a Momo Millennium Evolution merchandise, whereas the mix of that attractive Black Forest Industries gear knob and the CravenSpeed short-shifter makes gear modifications a pleasure.

This turbocharged R56 Mini actually is one thing else. It’s simply such an superior construct on each degree.  It’s acquired insane energy, a sorted chassis, killer appears and a full-on inside. Every thing’s been finished to such a excessive commonplace, and it’s such a formidable challenge – that is actual R56 objectives.

Unsurprisingly, once we ask Abraham about his favorite mod, there’s solely ever going to be one reply to that query. “The large turbo package. Placing it just because it’s our satisfaction to be the primary ones on this planet to have this setup on inventory internals,” he smiles, and it’s the cherry on prime of this next-level construct.

This turbocharged R56 Mini serves up all the pieces you may presumably need from a efficiency construct, and this monster Mini is the proper method for SpeedTech to point out off its tuning experience. SpeedTech by title, velocity by nature.
