I am trying to sort my conversion its an ST 170 engine and want to fit it into my mk1 cortina ,Anyone done this here ? Or can anyone help ,I have asked on other forums and ended up more confused than I started out lol.
Basically I have a mk1 cortina with hardly any wiring ,I have a St 170 engine complete ,And want to retain the injection system as I am happy with the 170 bhp as standard for NOW .I have the full engine loom ecu,key fuse box from a focus st 170 ,can I simply strip back most of the loom and just plug in the standard focus st ecu ? Or will it throw up errors and not work ? I cant afford an emerald /megajizzle thingy as I am all spent out on bits and bobs for now ,Also need most of the interior and window rubbers ,dash,suspension, bushes ,steering bits etc etc ,so I am trying to get this done on the cheap .
I also have the red ecu with a made up harness I bought off another forum but I am told it will not be any good for the vvt ?Unless theres a way to use it ? If all else fails are there Any cheap Auto sparks in Coventry who could help me out ?
Any links to wiring advice etc would be a great help.I am sick of reading conflicting advice and have trawled the net for weeks .Its information overload ,And its getting to the stage where I'm completely sick of the site of my car right now lol..Surely someone has stripped a loom for a focus and used it on a RWD conversion ?
Cheers for any pointers etc ,Ps can trade on welding advice or work lol

IIRC You can just withe the VVT on a switch so rather than a ecu driven VVT you can switch it in and out at will, don't be surprised with the Hp figures of the 170, its much nearer 150 than 170

Atmo V8 Power . No slicks , No gas + No bits missing . Doing it in style.
Austin A35van, very different------- but still doing it in style, going to be a funmoble

hi i can put you in touch with a mate of mine who makes bespoke looms , inc ecu mapping , he has a good reputation for wiring up cossys inc 24v into whatever also done plenty of zetec looms , v10 viper wiring , prety much whatever you want

I cant help with the ecu/wiring stuff but I just wanted to say 'oooofff'!
Gonna be a neat car when you get it running. Do you have a build thread up yet?

IIRC You can just withe the VVT on a switch so rather than a ecu driven VVT you can switch it in and out at will, is it a similar system to the Mazda VVT system? which is completly variable and needs an ECU to map the inlet cam timing for optimum power at different throttle positions as well as engine revs. from what i read the Mazda system is retarded at idle, then advances the inlet cam timing degree by degree as the revs rise then retards it again at very high revs. Honda's VTEC system is just on or off but the iVTEC also has the variable cam timing. problem with putting modern injection engine in different cars is that, even with all the electrics working properly, the different design inlet pipes/air boxes and exhaust systems will affect how the engine runs possibly causing a standard ecu the throw a fit. sometimes the ecu light will illuminate but the car seems to run fine or the car will have odd flatspots/hesitation which nothing will cure. i removed the injection warning lamp from the Datsun as it was constantly lit but it has never let me down. |

Cheers mate ,It has to be an aftermarket ecu I'm told :/

get the inlet manifold/ plug in engine loom from a mk5 escort zetec , ecu from a 130 spec 1.8 zetec of the same era
either escort/orion or mk3 fiesta ,.

Ford/Mazda share rather a lot these days, but i can only speculate on the ST170 engine, and can't help with the wiring. Not very useful then, but on the subject, i have fitted a vvt lump into my '85 Polo and i'm running it on carbs. The vvt is switched via a simple spring contactor which i've fitted to the throttle pulley - i can simply activate it via a heavier right foot. This VW unit is a single stage operation on the inlet cam only, so i merely have the choice of a torquey cam or a sporty one, whenever i choose (flawed of course, with them sharing static manifold bores/lengths etc etc sure, but it's better than a static cam). The carbs are the self regulating flat-slide type from a modern bike, so providing i keep my head, it's efficient and clean. |

Cheers guys I'm still in 2 minds on this ,I might buy some carbs for now and use the esc module and get thd vvt switched etc

From memory the ST170 engine uses a complex ECU that won't work without all the clocks wired up, so therefore it's useless for a conversion like this.

Virtually all the sensors except the CPS are in the inlet manifold. Rodney is right - this would be the easiest way although it's not ideal as it's technically for a different engine it will work. |

I have the red Esc module and loom like the banger boys use ,that would run it I'm told so the escort mk5 would be same ? How would i go about getting it wired up ?Any guides ?What exactly do i need? cheers guys wont be long on the spit nearly finished most of the welding ,All panels aquired:) Homeworks been doing my head in lol |

Banger racers use the Escort red box to run the ignition, they use a fabricated manifold to take a weber carb for the fueling though.
It's not ideal even for that really, a pre-PATS* (mondeo 93-95) ECU with most of the wires binned works better. However, these are mapped for a silver top engine, not a black top and certainly not an ST170 engine - even the black & silver top engines need slighty different maps, so yours will be more different and require the VTT wiring, and anyway, this is again only ignition. Megajolt Jr is only £100ish, so mapped engines on carbs are quite easy.
Personally, I'd start with a silver top Zetec engine and a pre-PATS loom, that will be quite easy to wire. Fit that, shake the car down and enjoy the summer, save over the winter to do the ST170 engine properly.
Out of interest - I assume the MegaSquirt solution to triggering the VVT on this engine (if it switches electrically?) is to run it off a shift light function with a relay?
*PATS = passive anti-theft system - uses coded key, a pain to wire.

If you've got the full loom why not just connect it up complete and lose the lighting wires etc?they connect up under the inner wing from memory into the fusebox on the passenger side.
The interior looms are the same on the focus on pretty much all models so getting bits and bobs from the scrappy should be very easy.
I've never heard of anything being controlled through the clocks on an st,certain cars do use it but I don't think they do.
It's only one plug if they do,just rip out an interior loom complete as well and take it from there,you'll get the diagnostics and everything else then with the full focus reliability .
Sounds a lot of work but it won't cost much and should be pretty obvious once you get going with the wiring diagram etc.
