    Lost Cylinder Compression

    Have a recent rebuilt l67 and lost compression in 2 cylinders. Both around 60psi. I have new heads to put on it but was just wondering, if 2 cylinders are down on compression would that cause a major increase in fuel consumption? Like 16-18l per 100 average? Thanks

    [Ecotec] L67 Rebuild

    I recently for an L67 that has been fully rebuilt but if course I'm going to strip it myself to make sure it's been done properly. He said it had JE forged pistons that has 20 thou over. Won't this make too higher compression? How can I add compression back to run more boost? Thanks
