    ST170 ECU/Injector/carb setup

    Looking for advice for ECU/Injector/carb setup for an ST 170 Silvertop engine in an escort Mk1.

    The two main contenders at the moment are

    Firstly the fairly expensive - Ford Zetec 1.8/2.0L (silvertop) Throttle Body Kit

    LINK - Omex

    OR the cheaper DanST Ford Zetec 1.8/2.0 Bike Throttle Bodies Kit GSXR 42mm *FAST ROAD PACK*

    LINK - DanST

    coupled with NODIZ Pro

    LINK - NODIZ VVT ECU

    To run the engine VVT

    Any thoughts or other suggestions????

    Thanks

    st170 isnt a silver top engine, its a black top badged as a duratec.

    re vvt, you cant control it with an ecu which simply switches it on a certain rpm, for it to work properly the ecu has to have a proper VVT map.

    from me an emerald K6 with part loom and a couple of sensors is £775 all in delivered.

    a k6 with jenvey ckfd03 throttle body kit and linkage ( but no loom) is £1680 delivered.

    you can save some money on the above by not having the full body kit from jenvey but instead buying a dcoe manifold from burtons/retro ford etc and my special offer throttle body kit.

    if all you want is the K6 then its £660 delivered.

    what ever way to go, doing it right isnt cheap

    The Nodiz VVT controller is mapable and 3D apparently.
    Regarding the TB's, its just down to what you want to see, as end of day they both will achieve the same goals.
    45mm Jenvey's may flow a tad more air over the 42mm GSXR TB's and so may work 'better' with the fully controlled VVT?

    Thanks - I'm really interested - is this it -

    LINK - Jenvey ckfd03

    LINK - Emerald K6

    Could you supply a complete kit with all the sensors,air filters, wiring loom etc. needed.

    Basically I have a friend who's helping me install an ST engine into a MK1 Escort - he's sold on the Omex system but hasn't really looked at any of the other systems available - I'm not convinced Omex is the way to go - in truth - I'm not really up to speed on the ST engine but I'm struggling to see the point of installing an engine with VVT and then having no control over it (not that I actually know what the advantages of VVT are -lol??)

    Really, any help gratefully received.

    You either need to fully control it or invest in cams etc. Or your wasting power.
    And You still need an ecu.

    Re: ST170 ECU/Injector/carb setup

    VVT Operation - think of it like cams control airflow and the efficiency of filling the cylinder determines torque output so normally there will be peaks and troughs in a torque curve if timing is fixed, but if you have the facility to move the cam around then the airflow and hence the torque can be improved in the troughs whilst retaining the peaks so smoothing the curve - thats the principle behind VVT.

    I'll be hopefully putting my order in with Graham for that lot tomorrow, air temp, water temp, tps included. As said you'll need a loom and injectors, but pretty much ready to go, I've built my own loom from the original focus one and have the original injectors to use also

    Thanks Guys - so its well worth getting an ECU that controls VVT.

    Re: ST170 ECU/Injector/carb setup

    a lot depends on how you control the vvt on some engines it can succeessfully be done by connecting it to a shift light, ie reach a certain rpm and simply switch it on, not so with the st170, it needs to be switched on in the midrange and off again at higher revs, so not something possible with a system which does a simple rpm switch

    Re: ST170 ECU/Injector/carb setup

    By not using the vvt and simply locking the cam at optimum power timing you don't gain or loose the peak power you can get.
    But at lower revs, approximately 2500rpm and below if the vvt is used to change the timing you gain a few extra horsepower and just over 20ft/lbs torque. So if your not after the maximum engine power spread you don't need the vvt.
    Also if you go for longer duration cams you will most likely need to go for fixed cams or get bigger pockets machined in the pistons.

    Re: ST170 ECU/Injector/carb setup

    not sure on above, emerald are regularly seeing 200 bhp on internally standard engines using full vvt control, just throttle bodies and decent exhaust add a flowed head and 210 bhp is on the cards.

    both figures quite a bit more than i see to recall these engines giving with out full vvt control

    ST170 ECU/Injector/carb setup

    I supposed if u know the exact advance for max power and lock it at that point then max power would be the same but it's likely to loose a lot everywhere else

    Graham - would you be able to supply a full kit - all sensors - complete loom - injectors - air filter etc. A 'plug and play' system with everything I need?

    Re: ST170 ECU/Injector/carb setup

    maybe, i can and do supply most of it, but im not sure about being able to do a plug and play loom.

    i will see if i can get a loom made, if theres enough interest i might even commission a batch of them
