Im asking for someone with experience here... what benefits would i achieve with a lean burn D15Z1(vx motor) or D16Y5 (96+ HX) over my stock D15B6 (HF, 8v sohc) ?? The motor itself has a very low powerband and i am averaging 49-50 mpg at stedy highway speeds. Im thinking most of the gain from the VX and HX cars are from the wheels and taller gears, so would there really be a benefit? added power is always nice, as the 70hp HF + tall gears can be pretty dangerous to drive on NJ 2 lane roads, but what about in FE? Any help appreciated! thanks!
