whats the difference between the 2? a guy i know has the z18 with FBW throttle and has done the bottom end. hes seen a few x18xe engines with cable throttle body. is it just a matter of swappin the inlet or even just doin a full bottom end swap? never worked on one before so any opinions are welcomed

cheers

the z 18 uses the internal crank sensor while the x is external, and the z has coated piston skirts while the x doesn’t, the only other difference could be the oil filter, some are canister, some are spin on, which cant be readily swapped about as the canister has no relief valve for a spin on in the block, so you’ll be able to swap them about really, but just the couple of niggles to sort

Z has FBW throttle body and throttle pedal. No EGR, using 2 lambda sensors instead.
Both suffer from unreliable ecus.
There was another thread along the lines of using the x18xe1 bottom end in place of the z18xe recently

The X18XE is a smaller bore X20XEV, so it wont be possible to swap as the stroke is different, the Z18 and X18XE1 have a longer stroke and smaller bore to improve torque.

z18xe's do have egr's. and having 2 lambda sensors have nothing to do with egr valves. they monitor oxygen content

Lambda sensor monitor oxygen content ?
Getaway.
:rolleyes:
Though my wording could have been better.
And yes, some z18's do have an egr, depending on the car theyre used in.

the z 18s do have a coating on the piston skirts, if the pistons are old it may well be mostly worn off, but it is there originally

x18xe is a big block engine like the c20xe, so yes you need the complete conversion.
If you have a x18xe1, which is a small block engine like the x16xe, it could be a direct swap.

2014 is a very late year, for that engine.
i think they stopped fitting them in UK cars, a few years before that.
chevrolets may have kept production rolling tho.

either way, the x18 uses a manual wire cable, on the throttle body, and the z18, is fully electronic, with just a wiring connector attached to the thtottle body
