    Z16XEP mods

    Hi all,

    I've never done any engine mods before so I have no idea about what's suitable and if things are worth it. If you could give me a list of things that are suitable along with their average prices and their affects on performance I will be very grateful.

    Thanks in advance

    Hey, i have a z16xep and the engine mods i have done are a vectra c intake pipe, de restricted air box with bmc panel filter and a cat back exhaust system from powerflow that cost £300. To be honest the only thing iv noticed is throttle response and noise. Although we aren’t really going to get much out of this engine without spending 1000's. That’s why instead of performance iv gone for looks until i can afford insurance of a turbo car.

    Thanks for the ideas guys. As I'm on a learning curve here what makes this engine so limited to mods?

    The Twinport Inlet arrangement prevents you from using a Mantzel type inlet on it.

    You can still fit a mantzel type inlet to the twinport engine altough it will be custom made.

    The mantzel replica powerbox is JUST a piece of aluiminium box-section with one end blanked off and one end drill for the throttlebody and a few holes tapped in it

    Im making one for my twinport. Its 65mm alloy boxsection with four runners onto a flange that bolts to the twinport lower manifold section. Basically identical to this 'box' but you make the four runners because the lower inlet they talk about doesnt suit the twinport
