    x18xe1/z18xe engine boffs help please

    I have done a search but cannot seem to find the answer.

    Other than the ECU and throttle system, are there any significant differences between the engines? Is there any difference between the head and the block on the two?

    Basically I want to know if I could buy a Z18xe engine and fit it to my x18xe1 using the TB/Inlet manifold, exhaust manifold and ECU and wiring loom from the X18XE1 engine? Basically only swapping over the head and block?

    Thanks.

    yes but there'd be no point, unless your current engine is knackered.

    I know that there would be no performance increase in a straight swap, I was just thinking building of a fast road spec engine, and whether or not I could use the Z18 that has come up for sale near me for internal modifications.

    A straight swap would give a slight power increase, the X18XE1 is 113bhp, the Z18XE is 123bhp. The cams are different as well as the ECU and throttle body.
