    Post certification query

    Unsure of this but have heard that you only need to certify a engine swap which has a greater than 20% increase in power..

    So does this mean I can go from the b16b (185 hp) to the B18CR (200 Hp) without a cert? As thats not a 20% jump is it?

    Just wondering and cheers for any replies

    Not 100% sure but I've been told it also needs to be certify if its capacity is increased more than 5%.

    Re: certification query

    pretty sure you do need one due to the jump in CC's

    cert is not required if the substitution of engines when compared with the OE engine, the replacement engine:
    – is of the same or less cubic capacity, and
    – has equal or less weight, and
    – has the same or less power output, and
    – uses the same fuel (petrol, diesel, LPG, CNG), and
    – uses the same unmodified attachment points and system (ie bolts-in), and
    – uses the same family of block and cylinder head from the same vehicle manufacturer, and
    – is of the same configuration.


    the modifications result in not more than 20% more power than the OE engine
    if you want it to be legal then get a cert, yes a WOF inspector might not notice but if you have an accident you may not be covered by insurance

    No, if you put in an engine that is 1cc more, cert time.

    Re: certification query

    From recent experience i failed wof for having a B18 block with the B16 head on as factory spec states its B16. $450 later and a month on and still waiting for cert plate to arrive.

    Re: certification query

    ^ Of course, its a bigger engine, if you had B18c internals in a B16b stamped block there is no way to tell though (B16b is same size as B18c just has different crank and rods for less displacement)
    You can be anything you like on the internet, so why do so many people choose to be stupid?

    Re: certification query

    What about a ef si zc running a b16a?

    ''uses the same family of block and cylinder head from the same vehicle manufacturer''
    Will it fall under this?

    No, needs cert because it's 1/ it's a different family of both block and head, 2/ it has more power and 3/ it has different attachment points.
