MazdaSpeed Miata Turbo System

The complete system engineered to get more power out of your MSM. This system will replace the stock turbo manifold, some intercooler tubes and the air intake system. The system is designed to work with the BEGi / FM (1st gen.) Intercoolers. The most complete system available for the MSM today.

This base system has been dyno'd with the Xede to produce:
243 rwhp @ 13 psi
252 rwhp @ 14 psi
the latest run is 253 rwhp @ 13 psi.

Currently, this system will replace the Air Intake, By-Pass Valve, Mid pipe, Downpipe, and Throttle Inlet Tube already installed. We can configure it to work with a Tial BOV or Greddy BOV. However, a BOV is not always recommended due to compressor surge.

Included in the Turbo System is:
*Garrett GT2860RS Turbo - Ball Bearing, Oil and Water Cooled.
*Cast Iron Manifold - Ceramic Coated
*Ceramic Coated Turbine Housing
*Stainless Steel Separated Gases Downpipe w/ Mid pipe -
Mild Steel optional, with or without CAT, three 02 Sensor Bungs
*Cool Air Box
*Air Scooper
*Water By-pass System
*Coolant Re-route
*Stainless Steel Braided Lines

Xede Engine Management
The XEDE (pronounced "x-eed") is the only user-programmable engine control system that works with the factory ECU for great performance and near perfect driveability. Every one of its functions has the resolution and flexibility to complement all factory ECU functions. The XEDE carries the tuning torch without inducing any compromise to performance or safety.

The MazdaSpeed Miata XEDE will illuminate the check engine light. It changes the stock ECU boost and TPS signal. Please contact us for more information on OBDII inspection. The MSM XEDE comes with 440 cc Injectors. The XEDE cannot change the rev limiter on any Miata. The XEDE Harness also comes wire for dual map switch, wideband O2 sensor integration and boost control.

MazdaSpeed Miata Intercooler Upgrade

With some minor modifications, this intercooler will directly replace the stock one. This intercooler is 32% larger and has 80% more volume allowing for cooler intake temperatures. In order to make your stock MazdaSpeed Miata more powerful, the intercooler upgrade is a must have.

The core is 3" x 7.5" x 18", and made with aluminum sheet endtanks. The intercooler can be powdercoated, however the shiny aluminum endtanks are beautiful. On the air intake side, and internal baffle is placed to make sure air is even directed across the intercooler core.

The intercooler comes with black turbo hose, mounting fasteners and hose clamps for easy installation. Recent revisions to the intercooler make it easier to install around the power steering cooler.

The only MSM Intercooler to include an Air Inlet Baffle (for better air distribution) and Power Steering Spacers for easier installtion!

MazdaSpeed Miata Cool Air Intake Kit

Replace the restrictive air intake on the MSM with the Cool Air Intake. The Cool Air Box isolates the air filter from the hot underhood temperatures to stay with six degrees of ambient. It will not pick up exhaust manifold heat that other Intake systems do. Exhaust heat will create denser air resulting in power loss and one step closer to detonation. The upgrade comes with the Cool Air Box, K & N Air Filter, Compressor Inlet Tube, two Compressor Outlet tubes, black turbo hose and t-bolt hose clamps.

$309.00 P/N 67009

BEGi MazdaSpeed Miata Ultimate Intake Kit

Incldes the BEGi Cool Air Intake, Forge Bypass Valve, and Throttle Inlet Tube. The Cool Air Box isolates the air filter from the hot underhood temperatures to stay with six degrees of ambient. It will not pick up exhaust manifold heat that other Intake systems do. The upgrade comes with the Cool Air Box, K & N Air Filter, Compressor Inlet Tube, two Compressor Outlet tubes, black turbo hose and t-bolt hose clamps. Add a downpipe and take 5% off the total price.

$498.00 P/N 67021

MazdaSpeed Miata Throttle Inlet Tube

The stock Throttle Inlet Tube balloons under boost and have been know to crack. The BEGi Throttle Inlet Tube directly replaces the stock tube. We also have two other versions available. The second tube will fit the larger Forge and Vishnu By-pass valves, with a 1" connection. The third tube is for use with the FM GFB Valve. All Throttle Inlet Tubes come with t-bolt hose clamps and black turbo hose. The latest revision moved the air temp sensor bung to the driver side to avoid crimping the wire.

$79.00 P/N 67005 for Stock Replacement
$79.00 P/N 67006 for 1" DV/BOV Replacement
$79.00 P/N 67007 for GFB Replacement

Forge Bypass Valve

The Forge Bypass Valve is a direct stock replacement. It is a Piston Recirculating Valve. It will sound more like a BOV than a recirculating valve. Available in Black.

$150.00 p/n FMDVMAZ

Boost Gauge

The BEGi boost gauge is 20 psi and 30 in vac. with a black face. It is 2" round and fits perfectly with BEGi gauge mounts.

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.
