[playr158]

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?

.2 overbore is huge. my car is only overbored .02 with JE forged 9:1 comp pistons, i still have the stock stroke and stock cam duration and stock timing.


boreing out a motor isnt really a "mod", its something you do when rebuilding/building a motor. if the pistons have seized up but you still want to use the block, you need to bore it over to recondition the cylinder walls. and the only time you would overbore a motor that much is if you are changing timing, stroke, compressions, duration etc... you dont just overbore a motor that much and just call it a day.
