Replacement Engine

[Robbie 2B]

I am looking for a Duratec HE 2.0 engine to replace the leaded Pinto in my 2B. As my post asking if anyone wanted to sell one got zero replies I am having to look at other sources.

 

One company which advertises on Ebay is Mondeo Spares of Stoke on Trent. They are offering a HE 2.0 with all ancillaries for £700 inclusive of VAT. Questions asked:

 

i/ Is it only me who thinks this is expensive?

ii/ Has anyone used Mondeo Spares and with what results?

iii/ Apart from the normall 'Parts R us' and '247 spares', can anyone advise a scrapyard/spares/parts company which has Duratec HE engines?

 

Thanks in anticipation

What about GBS, 2.0ltr Blacktop Zetec, brand new complete with coil pack, leads, injectors, thermostat housing and clutch £715.00 including V.A.T

 

I often wonder why everybody seems to either forget or choose not to support these guys.

 

Happy hunting

Try U-pull it, is it not easier just going for a black top zetec

John..... you sure your not working for GBS??

Q. Why a Duratec and not Zetec?

 

Can get a 2nd hand Zetec for 150 quid.

Duratec HE has exhausts on correct side for a 2B, chain driven cams, all alloy wet liner, 145 bhp without fettling and best of all its not a Ford design. However, if push comes to shove its looks as if it will have to be a Zetec.

 

Anyone want to add anything?

The Duratec can eat up money like no bodies business, Alot more is involved in getting it in a kit car, Your right though, It is good for power and reliability,

All the locost guys are now going over to Duratec and this is why the scrap yards are asking the premium,

 

Zetec would be your best option, However I understand some people dont wanna follow the sheep dog, Also Zetec would be your cheapest option,

 

 

Jon,

 

Stop it,,,,stop it,,,,stop it,,,,, you must be getting commision from directing people to GBS

The article in Complete Kit Car a while back looked ay BHP per £ for Punto, Zetec & Duratec.

Roughly the conclusion was that the Pinto became expensive after 150bhp, the Zetec after 170 Bhp and the Duratec after 200bhp, but you can getr 200 with just a set of cams.

Fitting the Duratec costs more because it's a Mazda engine, so bell housings don't fit.

However Its a great engine.

Shop around for a new zetec, pay cash. Tell em your in for an emerald ecu later in the year. Do whatever to get it cheap.

Hi Robbie,

 

First I don't think any one on this board would be removing a Duratec engine hence your lack replies.

 

I didn't read the article in Complete Kit Car but the BHP figure for the Zetec 2L Blacktop seem low. To start with the engine internals are good for 200 BHP so zero upgrade cost. Its all about removing the restricted inlet and exhaust to get the power available as is. Exhaust with no Cat, so 1.75" or 45mm primarys into a 3" exhaust pipe / silencer system. As you need another exhaust this zetec will be cheaper than any other engine. Inlet, 4 x 38mm bike throttlebodies on a good manifold and that should be about it. 185 to 190 BHP. With the inlet manifold the trick is to get the throttlebodies angled down the same as the inlet ports otherwise they spoil the flow.

 

So you don't need to "tune" the Zetec Blacktop engine, just the things you fit to it or any other engine, ECU, Air filter box, exhaust, inlet manifold.

 

There are some tricks I have found to mitigate the costs

 

Build your own Megasquirt for £170,

 

Use an escort secondary inlet manifold and ditch the lump with the single throttle body lump and the throttlebody, just stick 4 tubes onto this lump of aluminum which is your header with injection ports to match your throttlebody, watch the angle.

 

4 off better flowing injectors Sabb do a nice one with the original Zetec fuel rail.

 

Just don't forget some braces.

 

Ok, there other bits like water rail and sump but I am sure you have these issues with any engine you intend to use.

So I would have said the cost to tune your engine from standard are less for the Zetec when realizing 180 and about the same to get more than 150 BHP from your Pinto (Internal machining) or 200 BHP from Duratec. The ancillary pack needed for each engine will be about the same.

 

Try Aldershot car spares (Zetec £340) or Deane Woods Breakes (Zetec £80 take it out yourself £120 removed), both in Aldershot.

I think just changing the induction to get a 50bhp increase is probably a bit optimistic, certainly careful matching of parts and optimising induction and exhaust will give benefits but I would have thought a set of cams would be needed to get to the 180/190bhp mark

Hi Paul

 

ECU, decent carbs / injectors and exhaust system / manifold should see about 175 on a 2.0 Zetec once set up correctly. Very simple to fit it to the Bell Housing with just a spiggot and release bearing. Also suggest a lightened flywheel or a 1.8 one. Fast Road Cam and basic flowing and fettleing will see 200bhp but suggest start upgrading the engine after that with ARP etc.

 

The Zetec is a perfect match for a 7 being slightly lighter than the Pinto and easy to get reasonable power out of it. However, if you desire more than 200 ponies than the Duratec might be the best long term option although Raceline give a good idea of what needs doing to both(but at a price!!).

Hi Paul & Larry,

 

Yes Paul you may well be correct with 190 being optimistic and as Larry says 175 is realistically achievable.

 

The point I was trying to make is there is a vast amount of power hidden in the Zetec without recourse to tuning the innards. If I remember correctly the first internal thing to do is ARP rod end bolts above 200 bhp, then flywheel bolts above 250bhp. Because the engine was detuned for economy by restricting the induction it's a simple matter get them back. Again not absolutely sure, only read, the VVC on the ST170 was for torque not extra power and they had the CAT to contend with. I am sure I have previously posted a report of 190 from a Blacktop with standard cams. One tuning article says fit 2.0L Black top CAMS to your 1.8 silver top rather than a fast road cam (non hydraulic Silvertops only).

 

Again the red line has not been mentioned and power dose come in with RPM. Is the engine good for 7800 rpm for a red line? and 9000 with ARP bolts and balancing. Not exactly sure where to change the cam but it is way down the tuning route.

 

Yes Larry, a lightened flywheel is great. Start with a 1.8 and a Pinto clutch Assy. not a 2.0L flywheel. The mass of the 2.0L can only be got down to just under the standard 1.8L so spend your lightening money lightening a 1.8L. Further the centriffugal mass of the 1.8L and pinto clutch is nearer the center so it has a small amount of inertia, as well as the pinto Assy being lighter any way.

 

Hope that helps any any would be up graders. It would be nice if someone posted their Zetec Blacktop BHP with standard cams and details of induction / exhaust. Oh why a Zetec Blacktop over a Silvertop, the head porting is better and bigger while the inlet manifold is smaller and they both produce 135 and on some Focus models 140 bhp.

Quick question Alan that you might be able to help with.

 

Have you heard of anyone replacing the Hydraulic lifters in the Silvertop. I have a 136BHP early Silvertop which with the above changes should make the 175 I want but if I go above that, I'm worried about the increased RPM needed with Hydraulic lifters.

 

You've used both in anger haven't you? What do you think.

Hi Larry. No I have not used the Silvertop and I suppose as yet not the Blacktop. I have a Blacktop and it is about to go in, well I am still making some pieces, actually lots of pieces as I have completed a refurb on an LSD and disc rear brakes to do at the same time.

 

 

Any how your question on hydraulic lifters. No I can't remember any one saying they had to change them because of the state of tune of their Zetec E, over 175 bhp . My first thought would be there should be enough oil pressure to keep the lifter solid. Mechanical things don't change quickly, spoken by an electro mechanical design engineer, so I would not expect the lifters to sag under speed only have a greater tendency to stay the same, which is just what you want from a hydraulic lifter, the same length. So I would have thought the area of worry was tick over when the oil pressure is low.

 

It is Zetec Inside for early Zetec engine upgrades.
