I wouldn't mind going down the standard injection route as thats how the Zetec was developed to run but I personally have no idea how thats done using the Standard ECU.

Comment by Dave Adams on November 20, 2016 at 9:26: i have a few ford edis set up's but they only give a fixed ignition timing. it might be easy but not great. fitting the stock ecu and ignition is cheap and easy to fit.

Comment by Scott Grimson on November 19, 2016 at 20:44: Hi Dave. i have a CVH sump on it. The reason for the carb is that using a basic Ford ignition system is it's incredibly easy to fit and controls the spark perfectly. True it's not the most efficient set up but it's really cheap and easy to do. The whole engine sits too high i know, we were governed by the alternator bracket which was a bit of a bodge job, the running gear was first put into my old Rickman Ranger where space and hight wasn't an issue, now that it IS an issue i'll have to tweak a few things. The engine Brackets were made up and fitted on the day the engine went in and there was a lot of guess work!!! Haha.

I will almost certainly be going bike carbs at some point but will try a different inlet manifold over the next week.

If you have weighed them then you have something real to go on. However, your weight for the Essex is rather different from my measurement, which is a little worrying. I was just looking for a modern engine to compare with the Essex, to see how much lighter they are, and I was surprised by the Peugeot. It was the only 'modern' engine that I noticed in the list.

I prefer 6's because of their smoother low speed delivery compared to an I4 (I've never driven a V8) and when I looked through the list at straight sixes they are all heavier than the Essex, so it was not such a bad engine, in its day.

Comment by Big Vern on November 19, 2016 at 16:00: @JD I can only comment on engines I have had the opportunity to weigh. The PRV V6 from a DeLorean was 170kg and the Essex 3.0V6 from my old mk1 grannie was 243kg both engine only, fully dressed with ancillaries but 'dry'. I cannot comment on the Peugeot engine you refer to as I have not weighed one but my experiences suggest the Essex V6 is still heavier.

The Essex V6 is 1/2HP per kilo vs over 1hp/kg for the I4 duratec 2.5L so the modern engine still wins in my oppinion.

Comment by Dave Adams on November 19, 2016 at 8:36: i am fitting my spare zetec into my Legerra, some questions.

have you modified the sump? and did you fit the engine to give good clearance under the sump?

why go the carb route? fitting an ignition set up is almost as complicated as fitting fuel injection BUT it will give much worse running and fuel economy as well not giving better power.

i am fitting the fuel injection to the Legerra (as i have with my Phaeton) one of the reasons is to reduce the engine height that fitting the down draught carbs gives you. i can say that my pinto had its carb fully under the bonnet with the same type of air filter as your engine it even had the sump unmodified. true the sump was low but its a simple job to shorten it to give the 4-5 inches minimum to clear speed humps etc....

i would like some pictures of your engine mounts and if you have any of the clearance under the sump.

Comment by Dave Adams on November 19, 2016 at 8:22: i have had the zetec on the floor next to my pinto engine and the to the top edge of the carb the zetec was lower by about 2-3 inches.

Comment by James Doulton on November 18, 2016 at 22:29: @BV: I got the figures from gomog

Essex V6 : 430 lb = 195 Kg
Peugeot ES9 J4 3.0L : 473 lb = 215 Kg

The DeLorean used the earlier PRV engine didn't it? In the Delorean was 2.8 litre and only produced the same power as the Essex, but less torque. Okay, it was a little lighter but 30 years of engine design hadn't made a lot of difference.

Comment by Big Vern on November 18, 2016 at 14:37: "We tend to think of the Essex as heavy but apparently it weighs less that the 24 valve 3.0 Peugeot/Renault engine"

Nope the Essex V6 is way heavier, Fully dressed DeLorean V6 170kg Fully dressed Granada V6 243kg and the Essex produces such a small amount of power for such weight.

2.5 Duratec I4 produces more power and torque than the tug boat engine and weighs so much less!

Comment by James Doulton on November 17, 2016 at 21:46: Modern V6's are all very big, it's all those valves and cams. I had an Omega which had a huge bonnet, and it was full of engine. The good old Essex V6 is much more compact and has oodles of torque, it just doesn't make the power. We tend to think of the Essex as heavy but apparently it weighs less that the 24 valve 3.0 Peugeot/Renault engine.
