Essex v6 fuel injection??

[TashriqXLE]

So i have been researching fuel injection for my ford lately (3.0 v6) and came across an ad on gumtree for a 3.4 v6 ford courier's Fuel injection kit. both engines are Ford Essex engines. Will this work? If it fits what kind of electronics will be needed,if any?
Thanks in advance.

As far as I'm aware, the fuel injection setup on the Essex V6 engine was only ever available on the later "black block" 3.0L engine in the Sierra and Sapphire from the factory, never on the 3.4L and never in the Courier.

Not sure if the intake manifold fits the earlier "blue block" 3.0L engines.

As for the electronics, I'm not sure, but you will need a management system to control it all.

Maybe PM members LRW, Mad Sapphire and KSF, think they would be able to offer more info, and please share it here.

That setup is from the sierra irs. You can run an aftermarket management system. Ive got the mr turbo efi system. Spares are hard to come by for this system. It gives very good power. The intake for the blue block is different from the black block. But if you really want you can make it fit the blue block. Join the escort club for more help

For the blue block I would recommend the interceptor carburettors setup. There are some on gumtree but very very rare. If you look at the tappet cover on the blue block, the Middle hole that bolts to the air intake is off center and on the black block it is directly centre.

I figured the triple carb would be easier, thanks for the info guys. +1

What is the difference between the blue bock and the black block?
Is it performance? Year model? Design? I tried googling it but can't find much info.

The "blue block" ran from the Essex engine's inception until about 1990.
The engine block was painted blue, and it had the stamped steel valve covers with cork type gaskets.
There were differences in camshaft profile, compression ratio, inlet port and exhaust manifold design throughout its life.
But most 3.0L's are rated at 101-103kW, and 232-237Nm from the factory.

The "black block" engine came about in 1991 around the same time the 4x4 Courier was introduced, and was an SA only renovation to make the engine "smoother".
Compression was raised slightly, inlet valves enlarged, electronic rev limiter added, among other things.
The engine block was painted black, and it had aluminium valve covers.
The carb-fed 3.0L supposedly made more power than the earlier engine, around 110kW and 232Nm, again depending on the application, the Courier variant probably ran lower compression for poor quality fuel and made 97kW and 209Nm. The fuel injected Sierra and Sapphire versions were rated at 117kW and 260Nm.

In 1997, Ford introduced a carb-fed 3.4L version of the "black block" engine in the Courier pick-up, rated at 108kW and 260Nm. Note this was after JT Developments already marketed 3.4L conversions for the older engines.

Very nice info.

U can fit that system to blue motor and use the black motor tappet covers. Tripple carb or Holley 4 barrel route would be easier short term.
Looking at the pic of injection you would need some more goodies to make it work.
Besides management system you would have to mod your distibutor if you want to use hall pickup.
Or toss the dizzy and use crank sensor and trigger wheel setup. Easier to source these days. Get a coil pack, map sensor, fuel pressure regulator. Throttle is ok.
Is there some kind of wiring loom with it? The injector plugs etc would be nice if it does come along.
I have used the likes of Gotech and Dictator in the past and it's ok. Plenty maps etc floating around and easy to tune.

Now regarding the blue and black motors lots of difference as Indiana mentioned and some more.
The oil feed to heads on black motors different to blue. Cranks are beter, lighter rods and pistons. List goes on. The Courier bakkies never saw fuel injection only carb.
The black motors were dubbed high confidence level motors because it did not suffer the stock weaknesses of the older blue motor.
The JT 3.4 conversation used a merc rod and kombi piston if I remember correctly and The Ford was kinda a copy of it but Ford rods and pistons. These including the JT's were good for towing. Old man JT, God bless his soul was a great man and i met him once. He gave me some tips with the tripple carb tunings.
Having mentioned above mods the older blocks were imo stronger than the new blocks. We talking thicker casting and so on. The black motors have narrower oil galleries which made them quieter, different spec oil as well as adding coolers for oil.
I modded both blue and black motors in the past as well as mix the two.
Results were always great but my last black motor I built about 10 years ago was an absolute killer.
You can build a very very strong V6 or Stroker depending on wallet or bank balance.

Good luck.

Thanks for sharing that MS.

Has anyone ever fitted Toyota 20V ITB's to that intake manifold?
