    i have seen Holden007 talk of this 4.2 ltr stroker and i have a couple of questions as i am very interested...

    approximate cost of a ready done motor?

    approximate cost of stroker kit itself (if widely available)?

    around about how much power would you gain?

    has this been done very much?

    also if there are any places in WA that would have done this, please let me know.

    cheers in advance

    The kit comes from C.O.M.E. Racing man.

    Price is the same as the Ecotec kits, around $4,500 for the short motor and you must supply the engine.

    Good for 210kw at the flywheel. Will grab you some more info soon...

    Hopefully I'll be going with the turbo, also want to upgrade to heavy duty manual and diff, so I dont blow things apart. Good computer and intercooler, and it'll be sweet:w00t:

    cost of freight is included in those prices given...
    also in respect to one of your other questions, about how much power is gained....its not the power you should get excited about, its the increase in torque! thats the stuff that gets you up and going mate.

    ok so im interested in possibly getting the "custom boost kit to suit blower/turbo applications" but if i were i wouldnt be able to afford the supercharger straight away. would it make much difference stroking the motor with this kit and leaving it normally aspirated for a while? if it will then i am considering just staying with the normally aspirated version...

    please help me dr phil!

    seriously, its not a great idea to try run an engine built for forced induction, without forced induction...
    its really better to do it all at once, not saying you cant do what your saying...but its not the greatest idea. one of the biggest problems is that the forged pistons used have a low compression, to accomodate for boost, which you wouldnt have, which would make it run pretty crap.
    i wouldnt do it, but its not me we're talking about.
