Available Options

Color: All steel tubes for the turbo system come powder coated black. You can elect to powder coat it any color of your choice. We have powdercoated tubes a chrome silver color to a midnight blue color. It will definitely add a little pizazz to the overall looks.

Material: Refers to material of choice for the downpipe. The BEGI-S kit includes a mild steel downpipe. The stainless downpipe will do a better job of insulating the heat. It helps to keep the foot well cooler.

Wideband O2: The downpipe comes with a bung for the stock sensor only. You can add on a bung for the wideband O2 sensor. If you elect to add the WB bung, it includes an O2 bung plug.

Turbo Size: The S1 system comes with the GT2554 turbo, however you can upgrade to a larger turbo. The GT2560 is great for a little bit higher top end power and still retains good turbo spool. The GT2860RS is offered in two different turbine sizes. The GT 2860RS with the 0.64 turbine offers faster turbo spooling, while maintaining good top end power level. The GT2860RS with the 0.80 turbine is great for top end power levels.

Intercooler: The BEGI-S is non intercooled. You can add the BEGi-S intercooler and it includes the intercooler, intercooler tubes, turbo hose, hose clamps, and water bypass system. The intercooler is rated to 205 whp.

Fueling: The FMU is included with the BEGI-S system. The FMU will allow you to run 5 psi. The BEGi fuel system will add on the external fuel pump and allow you to run 7-8 psi when used with the Bipes ACU. The MegaSquirt is the most economical option for the 1990-1997 year Miatas. It is a standalone ECU and is capable of handling what ever power you throw at it.

Bypass Valve: The Bypass valve is used to eliminate compressor surge. On the smaller turbo, GT2554, it is not a necessity. However, it is a good idea for the larger turbos.

Heatshield: You can add a heatshield to protect your brake lines. A necessity for the larger turbos.

Oil Pan Drill and Tap: The BEGI-S does not include the drill bit and tap for the oil pan. It can be added on if you cannot source one locally.

Stainless Braided Coolant Lines: The BEGi-S comes with rubber coolant and oil lines. It is an economical solution, but you should expect to change them out regularly. They will wear faster from the heat. You can upgrade to stainless oil supply and coolant lines for durability and reliability. The upgrade includes a stainless oil supply line and two stainless coolant lines plus related fittings.

Separated Gases Downpipe: The BEGi-S downpipe has a separate gases vent tube for 2" to 6" depending on year of car. The fully separated gases pipe allows for faster turbo spool by smoothing out the turbulent flow of the air prior to merging into one pipe. The vent tube on the separated gases downpipe is over 15" in length. You can choose to upgrade to a mild steel or stainless downpipe.

Ceramic Coating: The ceramic coating is mainly for looks. It will not show surface rust like the standard black painted manifolds. The ceramic coating will have a small benefit for heat reduction, but it is not very significant on this application.

Stainless Steel Oil Drain Line: The S1 comes with a rubber oil drain line and two brass hose barbs. If you would like the durability of the stainless line, add it on to the system. The upgrade will include the stainless line and two AN fittings.

Gauge Mount and Boost Gauge: Offered separately in case you already have one or the other. A boost gauge is highly recommended! You will not know if you are over boosting without the gauge.

Cruise Control: We need to know if you have cruise control on the 1990-1997 Miatas. If so, we need to send you a bracket to relocate it. There is not an extra charge for the bracket.
