Introducing the All NEW BEGi-S Turbo Systems

New Installation Photos!

Performance:

While it has been known forever, in the engineering field, that proper turbos make more power and greater mid-range and top end torque than any known form of supercharging, either maximum, or at equivalent boost, now the enthusiast user is also becoming so informed.  Along with the substantial performance edge the turbo enjoys over the supercharger, the enthusiast is also becoming keenly aware that the turbo also has the significant advantages of: 1.  Smoother The turbo slightly improves the smooth driving nature of  the Miata, as opposed to the slight degrade caused by a supercharger. 2. More durable No form of performance improvement has proven more durable than a turbocharger.  With modest care, the Garrett turbochargers are easily 200,000 mile devices. 3. Less heat The turbo produces less heat load on the engine and in the air intake charge than any form of supercharging.  The reduced heat load is the prime factor in the greater durability of a turbocharged engine relative to a supercharged engine.  This is the fundamental reason turbos have powered every winning Le Mans racer since Charlemagne ruled the roost. 4. Better Economy Without the constant extra load on the crankshaft of driving a supercharger, the turbo freewheels to an enormous advantage in simple miles per gallon.  5. Quieter If you find the pure sounds of a performance four cylinder attractive to you, the turbo, unlike the SC will offer no interference. 6. Less Fuss The componentry of the turbo is both actually and inherently less fussy than any supercharger because it does not have that belt, two pulleys and an idler to misbehave at all too frequent intervals.

Objectives:

To provide the Miata enthusiast a substantial gain in performance at a very moderate cost.  The BEGi-S creates more power per dollar than any other Miata system in the world. Further, the BEGi-S offers the path to yet higher performance with proven components.  The BEGi-S Series has been configured specifically for the enthusiast who initially wants a healthy power and torque increases in the 40%/50% range.  If you have not driven a properly configured and properly tuned turbo Miata at 5 psi of boost, you will be astounded at the enormous gain in acceleration rates.

Results:

Superb driveability, quiet operation, cruise economy increases, and a smoothness that no Miata supercharger system has ever approached.  The turbo is the only power adding mechanism that does not degrade the Miata personality in any manner. The sprightly nature of the Miata remains completely intact with “zoom zoom” added on. The durability of the Garrett turbocharger cannot be matched by any other form of forced induction. The fundamental engineering behind the durability is a long story, but manifest in the fact that turbocharged cars have won all the great endurance races  continuously for decades, and no one dares even enter a supercharged car in the race.  Mazda's own American Le Mans Series car is turbocharged.     The BEGi-S enjoys exceptionally rapid boost and throttle response. The BEGi-S is also ideal for the entry level turbo system.  Unlike any other entry level system, the BEGi-S is completely expandable within the existing BEGi components all the way to our sophisticated S3 system.  The BEGi S3 system, capable of 300 bhp, currently stands head and shoulders in components, engineering and quality of design and manufacture, above any system offered by any other manufacturer. The BEGi-S and one casual Saturday's effort can change your Miata into a vehicle that will accelerate faster in 5th gear than your stock Miata will in 3rd gear.  All the while maintaining the same spunky eagerness to run that so characterizes the Miata.

Components:

* The same directed pulse exhaust manifold as used in our most expensive systems.     This manifold has been recognized repeatedly as the best cast Miata manifold in    existence * A genuine Garrett GT 2554 ball bearing turbocharger with water cooled center    section and integral wastegate * Mandrel bent steel air charge tubes, not the plastic inlet pieces left over from the    stock inlet * Powder coated air charge tubes * The most sophisticated rising rate regulator ever used in a forced induction    system.  (‘90 through ’97 cars) * Mandrel bent, thick flanged, downpipe * All welding is done with the artistic TIG machine * K&N Air Filter * Oil and water lines * All fasteners, hoses, clamps, etc., required for a remarkably easy installation * Comprehensive instructions

Why Buy BEGi? We have made a multitude of power enhancing and durability improvements to the1.6L, 1.8L and '99-'04 turbo systems. These kits has been designed by the turbo charging expert, Corky Bell, who has a designed over 100 turbo kits, of which have been featured on over 130 magazine articles and 16 front covers.  We are the oldest Turbo Kit maker in the USA, and we were one of the first with a turbo kit for the Miata. We have been working on Miatas for over 15 years and have built more Miata turbo systems than all other makers combined. We have designed, built, and tooled up these new systems with a passion and intensity that borders on insanity. We have brought the best of engineering procedures, materials, and processes to produce drive ability, economy and phenomenal performance. Below are photos of the new designs on the1.6L, 1.8L and the '99 to '04. Coming soon is are the supercharger system for '06 Miatas.

Frequently Asked Questions: Q: Why do some of the turbo systems not have fuel or engine management? A: Lots of customers have a favorite engine management system they want to use.  BEGi will not lock you into using our system. Some people prefer stand alone ECU's some need a simple solution. Q: Why is the Xede Engine Management highly recommended for the 1999 and up Miatas? A: The only way to change the ignition timing in the NB Miata is to install a new wheel and have it retard ignition timing all the time. So far, there is not a Bipes ACU for the 1999+ cars. This is not a good solution as the car does not drive well and will loose power and turbo spool. The Xede is the electronic solution that will add or retard ignition timing to an accuracy of 0.10 degrees. Q: Does BEGi give a discount if the Xede is purchased with the turbo? A: Yes. If you purchase the fuel or engine management system together, BEGI will give a 10% discount off of the cost of the turbo system and fueling system.

BEGi Component Quality The Turbo is  a Garrett T25 ball bearing, T28 ball bearing, or a T3. Oil and water cooled. The Manifold is cast in ductile iron. The design is the most efficient and reliable one available or proposed with spacious wrench clearances and careful control of thermal expansion. NEW Manifold Design!!! The Air Scooper directs air flow directly into the radiator, bypassing the intercooler. Overheating problems, due to cooling air blockage created by the intercooler, are greatly reduced and often eliminated with the Air Scooper.  We have a version for the Miata with the R package as well. It bolts directly to the intercooler. The Radiator Cover aids the Air Scooper in air flow. It keeps the cooler air from escaping over the top of the radiator. The Intercooler has been revised to a 'long' tube design. (the previous version was a short tube). The core itself is aluminum, bar and plate style. (Not an e-bay or China special!) The endtanks are wrought aluminum, and the  intercooler mounts directly to the frame. Why did we go to the long tube design? It removes more heat, with minimal drag. It does produce slightly more drag than the short tube design, but the slight additional drag is clearly offset by the enormous increase in effectiveness. The Cool Air Box totally isolates the air filter from under hood heat. It aids in providing cooler air to the turbo, so the increase of temperatures when under boost are even less. What is this distribution block? It's the new simple, convenient, durable, and  central "port" for all oil and water supply lines to the turbo. The turbo oil and water supply lines have all been upgraded to stainless steel braided lines for added durability.
