    i want to get more torque through out the rev range on this
    engine i fitted to my renault 9 .
    i have allready backed it up with a group A induction kit
    and a 2" scorpion exhaust and ,
    those two on their own made a
    remarkable difference response and pull wise .

    now what else can i do to get a more torque efficent engine
    without loosing the daily drive comfort and reliability ??

    A lighter flywheel will free up some power.

    A lighter one off the shelf means you'll be off the road for a day - getting your flywheel lightened can take up to a week. The end result is similar although some lightened flywheels are constructed of special materials so just drilling holes in your flywheel can upset the strength of it.

    no problems i got a spare engine here with
    the fly wheel attached .

    so what sort of gains am i looking for ,with a
    lightened flywheel ???
    would not using smaller or lighter wheels make
    the same sort of affect ??

    The flywheel rotates at 2000-5000 rpm so it would be much more noticable than fitting lighter wheels.

    i see and it makes perfect sense 8)

    how about getting the crank lightened ,balanced etc ??
    like i said i got a complete spare engine to work on .
    i want to get anything i can do to it without buggering the
    daily drive reliability !!!

    cause i know maxing engines up cause them pop sooner rather
    than later unless you spend a fortune on them .

    Lightening and balancing will help improve reliabilty - no harsh vibrations so everything should run more smoothly. Large valves and getting the head gas flowed will help with power gains and you still shouldn't be sacrificing reliability.

    I recommend you to buy DENSO IRIDIUM PLATINUM LK22 spark plugs. I bought it for my R19 16v PH2. Super. Satisfaction guaranteed!
