Has anyone ever bored a c20let out to 2.1? Or are the blocks not strong enough for that?

The most you'll get out of a 2.0 bottom end is roughly 2050cc. There is not enough meat to get a healthy 2.1. To be fair, you are better off looking in other directions to get more power out of these engines. Go for some 88mm pistons if your bores are worn and need re-surfacing though

Saying that, there was a guy a while back on Mig who was selling parts like H beam rods and bolts to string up a 2.2 litre bottom end for them. However, they don't like being revved as much as the rods are a little long due to that bottom end being a stroked version of the 2.0...

If you go to 88mm bore you get 2083cc IIRC so thats basically a 2.1 when rounding is done. (EDIT:Think that might be 2092cc?)

It is often said that you shouldn't really go over 87mm bore due to the wall between the cylinders becoming too thin and getting bore flex.

88mm bore would be;

(44x44)x3.142=6082.912

6082.912 x 86 x 4 = 2092521.728

2092521.728/1000 = 2092cc

Piston area is pi x radius x radius

Then total volume is piston area x piston stroke x number of cylinders

Then finally just divide by 1000 to get the correct units.

I believe it is in the Haynes manual - are you looking for it for your 1.4?

Well from my googling, I have found the stroke is 73.4 mm, and remember the X14XE isn't a 1400 cc engine, its a 1389 cc.

X14XE is 77.6mm bore (pistons) with a 73.4mm stroke on the crank. It is an oversquare block, whereas the C/X16XE is undersquare as it has a 79mm bore and an 81.5mm stroke.

The C20XE/LET is a nice and easy to remember square block at 86x86 as standard!

The volume is the pi x radius squared x the length of the cylinder.
