Guest FrantiC Report post Posted October 7, 2009 Yup. But why not just start with a m20b25/m20b27 block? Save yourself the money boring it out that much.. You can bore m20 blocks to 86mm Quote Share this post Link to post Share on other sites

You can bore m20 blocks to 86mm Cause if you bore a 80mm to standard 83.98 you have basicly a new standard 2.5L block. I have a set of mint standard 11:1 eta pistons that I don't want to slap in an old block... Quote Share this post Link to post Share on other sites
