ok my friend has a 1.8t jetta and then she mod'd the hell outta it.
my biggest interest is the engine bore from a 1.8 to around a 2.5 which is really sweet and FAST. she used a .018 overbore which is sweet. i wanna know if i can bore my 7afe at .018 or .02 i really want the .02 but the .018 or .019 is nice too! so can i do it? what will i need, and about houw much? |

BRINGING THIS POST BACK! haha. anyway. im not very familiar with bore and stroke so dont bag my knowledge. but wouldnt increasing the bore increase horsepower, since there is a greater vacuum during the intake stroke created in the cylinder, bringing in more air and fuel, allowing for a larger more powerful explosion? i know that sounds a little intuitive, and it might be a misconception, so feel free to clear it up with more mechanical knowledge. Also, increasing the bore weakens the engine based on what it is bored to, but by how much would it be weakened from about a 1/5th of a liter bore?
