Features

At the heart of this turbo system is a Ball Bearing BorgWarner EFR(Engineered For Racing) Turbochargers.
These Internal Waste-Gate EFR turbochargers also feature Built In Recirc Blow Off Valves, & 3 Port Boost Control Solenoids built into the compressor cover.
All of these features in one package reduce the complexity of your turbo system.The turbo is also positioned as low and as far back as possible for extra stealth and a low center of gravity The internal waste-gate configuration offers considerably less noise than open dump tubes. This is more desirable for street and track cars with decibel limits. Furthermore one does not have to worry about melting your external wastegate lines, or blowing your waste-gate diaphragms( common on road course driven cars with external wastegates). The internal wastegate is also a divorced unit, with two separate runners leading up to one single 42mm waste-gate valve. This is the best internal waste-gate design of any turbocharger. This turbo system is a true twin-scroll unit. It completely separates the exhaust pulses between the two rotors. This separation not only makes more power, but increases boost response. The internal 42mm waste-gate has been proven to properly control boost pressure on a 13b without any creep at medium boost levels( see attached chart of 12 psi).
This turbo system comes standard with the medium waste-gate canister. Boost pressures lower than 12psi require exhaust restriction( A Catalytic converter, 2.5" exhaust system, or a re stricter insert). A TurboSmart EFR IWG dual port actuator is recommended for those who wish to run both low( 10-12psi, and very high boost pressures with the OE EFR solenoid.
Every piece of this kit is 100% built in the USA and is constructed with the highest quality materials & components. Every single piece of this turbo system is designed for the highest reliability and performance that money can buy.

As of 10/17/15 this turbo systems will now include our new 347SS investment cast EFR IWG T4 manifold. This manifold comes standard with twin 1/8 NPT exhaust gas temperature or exhaust manifold back pressure ports( plugs included).

At the heart of the system is a EFR 7670 T4 .92 Internal Waste-gate Turbocharger.. The 7670 will deliver the fastest boost response, and lowest boost threshold, and is perfect for a 350 to 400rwhp street, or AutoX car.
The 7670 will make over 450rwhp at high boost pressures.
