engine bore

[plasticsurgerydisaster]

sorry if this has been asked before, how many litres can you get out of the k8 1.8 litre engine when bored 100 over

There is no "number" or size anyone can tell you because not many have tried. (much easier and cheaper to just use a 2.5L block) Your best bet is to show you block to your local engine builder and get his idea. If you go bigger then an available oversized piston (IIRC .040) your next problem is to find a piston that you can use, if you go with a custom piston your looking anywhere from $550-600.

FYI: (stroke x area of bore) x number of cylinders
Area of bore = pi x radius squared<p>75 x 69.6 mm is the bore and stroke of the 1.8
mm x .03937 = inches

can the math expert show me how to figure it out i cant seem to get it to work. and what is pi?
Lets say i have a 75mm bore and a 74.2mm stroke.

pi = 3.142<p>so cc's = stroke X 3.142 x bore x bore / 4<p>so using your numbers of 75mm for the bore and 74.2 for the stroke you get:<p>cc's = 7.5 x 3.142 x 7.42 x 7.42 /4<p>= 325 per cylinder<p>or 1946 cc's or 1.946 liters for the whole V6

whats pi? have you ever taken a math class in your life? j/k

[mrspanky79]

when he said pi i was trying to think what messurement in the engine that pi would stand for not the math equation pie.

Basically if you bored the K8 100 over then you would end up with a KF, but spend more money for it.
