The BEGi S2 Turbo System features components for the perfect street turbo system. It has great response, great power, and all the reliability features BEGI is known for. Also included are the Cool Air System parts, such as the air scooper, radiator cover, and the cool air box. BEGI turbo systems feature power improvements that no one else has. Such as a 18" separated gases downpipe, larger intercooler rated for 250 whp (a/c compatible), and the directed pulses feature in the exhaust manifold. The downpipes for the 1994+ Miatas all have a 2.75" outlet. The 90-93 Miatas have a 2.5" outlet on the downpipe.
BEGI has paid close attention to temperature reductions through out the system. The Stainless Steel coolant and oil lines to the turbo are more heat tolerant, well beyond the requirements. They are designed to be installed once and forgotten. BEGI thinks it is ridiculous that one would have to change rubber/silicone lines every year. The larger tube intercooler has sheet metal endtanks with a bar and plate core. It also has rigid mounting points. It cannot rub on a/c lines and wreak havoc. The system also features t-bolt hose clamps on the boosted tubes. The t-bolt clamps are a little tougher to install, but over the long run no clamp is better suited for the job. The kit comes with black powder coated tubes and black turbo hose. This system, when installed with the BEGi fuel system and Bipes ACU, has a CARB EO for 1990 to 1999 Miatas.
BEGI also ports the turbine housing on the turbo. It is the extra mile we go to help ensure that your system does not experience boost creep. When using the wastegate actuator for boost control, porting the turbine reduces boost creep 99% of the time. If you would like to use an electronic boost solenoid, do not be surprised if you see some boost creep. That is just the nature of some electronic control units. BEGI is also the only kit maker to use 10 mm studs to mount the turbo to the manifold. It is a well documented fact that the 8 mm studs will break.
BEGI has also placed alot of emphasis on the overall look of the system. A clean and balanced design makes the engine bay pleasant to look at. You will not see rubber lines running to and fro with a BEGI S2 Turbo System. BEGI also ceramic coats the exhaust manifold and turbine housing. It helps to ensure the good looks of the system over time. It also helps to reduce under hood temperatures.
Have you ever wondered how close attention we paid to detail? Here is the answer - there is only two intercooler tubes that can be used on two different year cars. Every single tube has been designed to fit that year car and that year car only. Some people might call it a little much, we call it easier to install.
We have the parts needed for all RHD cars too! Please specify that you have a UK sped car on a 1.6L motor so we know to include the correct exhaust manifold and oil supply line. This feature is available for all turbo systems.
The BEGI S2 Turbo System has various power levels it can achieve. The power it can run is totally dependant upon the engine management system you choose. The S2 Turbo System can be purchased with or without engine management. Chances are we have you covered though. Running 5-6 psi will produce about 150 whp using a BEGI FPR. Running 8 psi can net power levels of 170 to 190 rwhp when using the BEGI Fuel System and Bipes ACU (90-97 only). If you choose to use a standalone ECU or Xede, power levels can be in the 200 to 230 whp range. If you are using this system on a 99-05 Miata, we strongly recommend the use of the Xede. The 99-05 Miata must have some form of ignition timing control in order to avoid breaking the motor. We have seen some Miatas running in excess of 250 whp with the GT2554 turbo, but it requires the use of a standalone ECU and race gas.
