Another question for all you motor gourus out there: If I wanted to go 20 thousandths over(3.209" or 8.15 cm total bore) instead of 10(3.199" or 8.13 cm), what kind of issues would I run into? Is this a dangerous amount of material to take off the MC Block? Thanks -Marc- 87 4kcsq awaiting turbo 87 5ktq donor
