    Difference between Z16XE and Twinport?

    Is the difference between these two engines purely the throttle body at a guess? Am assuming the Twinport engine has a TB with a second intake port for when you're 'giving it some'?

    There's 15bhp OEM difference between the two engines, what's the odds of (if the engines are similar) fitting the Twinport TB and perhaps intake manifold to the Z16XE? Would it let you access these extra little ponies?

    Or am I guessing completely wrong and I need a good slap for being silly?

    Its the inlet manifold and ecu that are different. I'm 99% sure you can't reprogram a z16xe to a z16xep. The engine wiring looms will be different too.

    You're completely wrong nry. There's 5hp difference between the normal 1.6 and the Twinport. The inlet manifold is different, the timing belt and water pumps are different.

    The 1.6VVT is the 115hp unit and is pretty much the same as the PSA/BMW 1.6 unit from the Mini.
