    Default 20v Valve Train Package - Custom made by Ferrera

    Hey Guys,

    So we are planning on getting some custom 20v valve train package kits from Ferrera.
    They have designed a kit for the blacktop head which allows 12mm lift.
    The kit was designed for a guy in the USA who wanted the best of the best.

    The valves have been specially designed with a special shaped tulip on the stems and a flat face on the valves.
    Valve springs are based on the Moto GP bikes and good to 15k, comes with Titanium retainers.
    Note: The oem retainers cant be used in this setup.

    With mild porting the head flow is good for 280cfm plus! at 10.7mm lift.
    A supertech package is only good to 250cfm.

    Ferrera did extensive research and found in their design the valves would remain the stock size, this flowed the best at the high lift. Going over sized created shrouding issues at these lift levels. If the lift was under say 9mm then 1mm OS works better.


    The complete set is $1250AUD


    Its about $400AUD more than a supertech valve train setup but its gona flow a whole heap more!

    You would need around 9k.
    If you got smaller duration cams and made the lift near 10mm you could lower the RPM.
    Even the same lift but smaller duration like 272 not 300 then less rpm needed.

    I know im def getting this package for the best possible 20v BT head! No point getting the supertech stuff when for a bit more you can grab a whole heap more power. In Turbo form it will grab HEAPS more power. You could then run alot lower boost to get the power you want which means way less stress on the engine = will go forever!

    sooner or later you are going to cave and buy all this shit for your car garth. just accept that you will never be rid of the rolla.

    or get an AE86 to put this stuff into

    The only way i'd be buying everything for this engine is if (/once?) it looks almost certain there is going to be a 4A-GE powered replacement for it i could transfer it all into. I'm not putting a $10k engine in the rolla (unless i know i'll have something else to use it in). Right now, my heart is probably looking elsewhere, but who knows where it'll be once i actually have the coin burning a hole in my pocket. I'd really really like a silly 20V but it doesn't seem like the best use of spare dorrars right now...
