BorgWarner Turbocharger EFR B1 7163F 0.85 a/r VOF WG

The 7163 features a smaller frame and A/R than the 7064, but larger than the 6758. It's designed to better maintain boost than the 6758, and spools up much quicker than the 7064, slotting it perfectly in between the two turbos. This is an off-the-shelf Indycar turbocharger, used by all 2014/2015 IRL teams. It's a versatile turbo with a very large map width for outstanding power potential even at high boost - and does it in a small package. Excellent for autocross, rally, drift, road racing, and street-driven applications. EFR 7163 uses the smallest-sized EFR compressor housing, fitting in the tightest engine bays, particularly twin turbo V6 or V8 applications. In twinscroll T4 configuration, the 7163 delivers mindblowing fast spool and response while working well on stock and modified engines. Ideal for use in single turbo applications for the 300-550hp range, or as twin turbo applications 600-1100+hp. Ceramic Ball Bearing only, watercooling mandatory.
