Uses stock crank pulley. No oversize expensive crank pulley required for higher boost. And it fits under the stock hood. Only a Kenne Bell BOOST-A-PUMP is needed for 700HP. No larger pumps, lines, rails, injectors necessary. After 700HP, upgrade the fuel system. We recommend using 2003 Cobra style rods and pistons. Use 60lb injectors and Big Oval Throttle Body

Same features as 2.6 but better choice for modified engines as heads, headers, exhaust and stroker kits reduce boost, .75" longer case for higher boost/HP capacity. 2.5 psi more boost with same pulley size vs. 2.6L. Minimum boost is 14.5 with stock crank pulley. Max 26 psi.
