I thought I was pretty clear on my idea of engine specs. Some debate would be nice without getting too bent out of shape. 2400cc's kind of limits engine choice to the Good old Ecotec and a hot rod 2300cc Esslinger. 2500 cc's open the choice to several more motors that might be successfully raced including a larger Focus Motor. Making after market rods and pistons legal will only add a lot of expense to the cost of a motor. For the cost of your rods alone you could buy a low mileage late model motor. Like bike motors my choice would be to pay extra and buy a low mileage newer engine that does not require rebuilding. If you chose to rebuild an older motor most DIY people have no way of controlling their dimensions and may just be building a bomb. The factory does a much better job at putting engines together. Or PAY for the expertise of a reputable engine builder. Keep the motor rules simple try to make it so that a quick visual inspection with a bore scope will cover most instances. Do not throw away your measuring tools just in case. Keep it fun and affordable and don't make it ecotec only.
