The lowest possible price for a BW EFR 7163 with an external wastegate (EWR) and a v-band style 0.85 A/R. Other variations are available in the drop down menu.

This turbo is available for any engine and is incredibly efficient. If you're installing this on a 1JZ or 2JZ motor expect boost to come on just over 3,000 rpm's and then pull hard to red line. Turbo will make 525rwhp on E85.

When building a kit around the BW EFR line of turbochargers remember ALL EFR turbos have a built-in blow off valve (BOV) and a built-in (to compressor housing) boost control solenoid. These two items help reduce cost (you don't have to purchase a boost control solenoid or bov) and the associated plumping and fitment challenges that come with external units.Another advantage of the EFR series of turbos.

A Boost Control Solenoid Valve (BCSV) is included with every EFR turbo -- For electonically controlled boost levels, an Electronic Boost Control Solenoid (EBCS) is integrated right into the compressor housing. This solenoid is truly OEM quality and uses an industry standard fuel injector plug, making it easy to connecting to multiple boost control systems. Of course if the hardcore racers want to use an external solenoid OR a manual boost controller (without the integrated EBCS), that is very easy to do.

EFR turbo compressor housings incorporate an integrated BOV. Yes, you read that right - the BOV is a recirculating style *built-in* to the Compressor Housing. The major performance advantage in this design is that it redirects the high-pressure compressed air from the outlet of the compressor wheel -> right at the low-pressure inlet of the turbo.

This helps to keep the turbo spooled between shifts and offers cost savings/convenience while keeping MAF-based engine mgt happy. With this in place, there is no need for a BOV or flange on the charge piping. The only downside of this feature is the fact that it makes the compressor housing about 1" (~25mm) longer in axial length.

For the hardcore racers who want to use an external traditional BOV, and for applications that can not fit or do not want to use the internal valve, we offer a disabling cover plate. This cover plate installs in place of the plastic cover and uses the original diaphragm to seal the port.
