Summary

    1.8 swaps are becoming more and more popular and with good reason. It's a simple way to get more power. In the past, there was some fabrication involved. Not anymore - this kit includes everything you need for the swap. All the parts are available separately as well.

    • EGR plate kit
    • throttle cable bracket
    • coil bracket
    • motor mount brackets (optional)
    • rubber motor mounts (optional)
    • throttle body adaptor kit
    • electrical parts needed to extend your CAS wiring

    If you're using a stock intake or don't want to swap thermostat necks, the hose splice will make your life a lot easier.

    For more information on how to do a 1.8 conversion, please see the writeup in our technical section.

    Your 1.6 computer does not require EGR, so you can either leave the plumbing in place or remove it. If you do the latter, 1994-1997 and 2001-2005 exhaust manifolds will need an EGR cap while 1999-2000 exhaust manifolds will need an EGR plug.

    The coil bracket is not compatible with VVT engines.
