"Thank you for contacting STS Turbo regarding our remote mounted turbo systems!

The patented STS SINGLE TURBO SYSTEM for only $1995 and the STS TWIN TURBO SYSTEM for only $2995 are a great Value. You can put the turbo wherever you want which gives you endless possibilities for turbo placement. By remotely mounting the turbo you simplify the installation and you completely stay away from the damaging and power robbing heat produced by a manifold mounted turbo. The STS system uses a SCAVENGE PUMP(2 for the twin) that is included in the kit together with hoses, fittings and electrical components to turbo charge your vehicle. The STS oil pump equipped with an ALARM system to notify you of a malfunction will take the oil from the turbo and pump it back to the motor and can be fitted to the valve cover for ease of installation unlike typical front mount systems that require tapping the oil pan increasing the installation time and cost. The kit also includes the correct size STS Turbo ('S) for your motor and horse power goals, a reusable High flow STS air filter (x2 on the Twin System), STS/Turbosmart 38mm Wastegate std with a 5psi spring (x2 on the Twin System) that is upgradeable to the boost level you desire, Flanges for the turbo and wastegate for mounting, a comprehensive installation instructions manual and a 1 year warranty. Optional components are available....

this is their answer...
seems so perfunctory, nothing is on the point.
