We were the first ones to put EFR7163s into the stock housings on the 2.5TFSI. The result is a near stock spool 57/71mm comressor 60lbs/min compressor coupled with a big 57mm turbine, ball bearing and an exotic Titanium Aluminide. We see 500bhp (440whp) on pump 91octane (95 RON), 525bhp on 93 octane (98 RON) and 575bhp(500whp/500wtq) on e45 which the stock fuel system will support on an upgraded HPFP.
An $850 Core Charge is required for the $2,999 price if you can not provide a core.
Typically in stock, we will contact you if the stock is backordered.
