I want to change the 1.6 zetec engine in my H4 for a 2 litre zetec.

There are lots of Blacktop engines available with sensible miles and cost, but low mileage Sivertops are not so easy to come by.

I have looked at lots of info on the internet and so I have a reasonably good idea of the work involved in the swop.

However I am not sure if the Blacktop is going to present more difficulties in fitting  than the Silvertop, could anyone give advice on this?

Thanks

Andrew

Yes, it will be more work but nothing insurmountable.
 
The first thing to think about though is probably the engine management.
All the black top engine ECU’s will be coded to the key so you need to make sure you buy an ecu with a matching car wiring loom, ignition key sensor and ignition key.
The best thing to do is buy a written off but running car, then you can get all the parts you need.
Don’t go too new though as i believe on later cars the instrument cluster can also be coded to the ecu and the ecu won’t work without it.
I’ve not actually confirmed this myself.
 
The alternative is an aftermarket engine management system but ideally still get the Ford wiring loom for the engine so you have all the correct plugs for the engine.

I can confirm the issue of needing the instrument cluster – whilst I was still at Ricardo (10 years ago!) the Noise Lab had to have the whole vehicle parked outside and extension wiring into the anechoic chamber if doing noise reduction work on “modern” engines or else it was not possible to start the engine.

Can you not just swap the to a 2.0 Silvertop's ECU (EEC-IV), as that will keep the same harness and sensors connections as the 1.6? Finding a suitable DEEP, DESK or DEWY ECU might be more of a problem these days though.

The silver top ecu won't match the black top injectors, AFM or the cam profile etc.

Hi,
I am running a Blacktop in a 2+2 but using the silvertop inlet manifold as the black manifold is too big, I am using a omex 600 ecu. I do have a omex map for the standard blacktop engine if you decide that route it was sent to me by omex.
I also had to grind away some of the alloy sump to allow the starter motor to fit which is on the front of the engine.
The blacktop engine also has solid lifters.

I second the need to remove a lot of the sump webbing to fit the starter, but mine went into a north-south layout.

Carbs are always an option if you don't want the expense of injection and ecus.

The blacktop engines do have some other nice design features - such as the builtin windage tray in the sump, and on the 2 litre there are oil jets into the underside of the piston crowns.

One other issue that people sometimes raise is the direction of rotation of the waterpump. On the silver tops you can just change the pump, but there isn't an oem reversed waterpump for the blacktop.
Plenty of people run it backwards without problems.
I used a custom reversed impeller imported from the States.

ISTR on the silvertop that the Escort and Mondeo waterpumps could 'do the
same job' but ran in opposite directions (not expressed well but you know
what I mean) - is that not the case for the blacktop?

I believe the blacktop water pump rotates the opposite direction to the silver top, so watch out for serpentine routing.

You can get a after market pulley and mount it on a bracket to run the
belt the other side of the water pump and thus making it work
correctly I 've done this on my H4 you just have to line it up seems
to work fine.

Just looking into this a little more I am not all sure that the RS 2000 engine is a Silvertop.

I am particularly thinking here of the compatibility of ECU's and ignition circuits.

Additionally I have read that if using a 2.0 Zetec in a Fiesta (H4) the standard inlet manifold is the wrong shape/too big and the best one to go for is the RS 1800 manifold, I was wondering how this compares with the RS 2000 manifold in terms of size/shape.

No, it’s a totally different engine, most similar to the twin cam used in the Sierra and Granada.

Having looked into this further I concur with Jim, the silvertop zetec 2.0 engine is definitely the most straightforward replacement for the 1.6 Fiesta zetec, although I think the blacktop does have the benefit of advances in the overall development of the zetec engines. 

The blacktop could be fitted but there are far more complications than are initially apparent, some parts of the engine have to be removed with a grinder to allow clearance, the engine mountings need modification, the pulley/water pump arrangement also needs modification and there is the ECU/ignition  to deal with etc. By comparison the silvertop seems a doddle!

The next task is finding a silvertop engine with sensible mileage, given that these were phased out for the blacktop in 1996, as far as I can ascertain, this probably wont be that easy, I will keep a lookout for either an engine or an old Mondeo thats been well cared for but has seen better days!

Please can anyone tell me - what is black on a black top engine or silver on a silver top?
 
What are the main structural differences that enable one to be distinguished from the other?
 
Thanks.

It's the colour of the the rocker cover.
Silver aluminium on the early Zetec and Zetec-E and black on the revised Zetec-R (i think it's actually plastic).

You can of course find engines where the silver rocker cover has been painted black.

Other differences, the silver top has a one piece allloy sump, the black top has a 2 part sump with a aluminium section and a small steel section below.
The silvertop has the waterpump on the end of the block, on the blacktop it's more forward, just infront of the black.

Hi Andrew,

I may be able to help here... I purchased a stage 2 tuned Specialized Engines 2L Zetec silver top from a friend who was breaking a show car to put in my partners H4 ages ago, but she crashed a different car and decided more power in the H4 was not a good idea. It has sat moth balled, along with a stainless manifold, gearbox which 'apparently' has an LSD in it but one broken lug AND a low mileage 2L zetec complete with ECU which I acquired just in case for the last 4yrs. The Specialized engine was apparently built on a new block and had only covered 12k miles, have no reason to doubt but no receipts either.

Whole lot can be had for £600, manifold with heat wrap is worth £200 alone!

Hi Colonel,
An LSD is quite easy to prove because if you rotate a drive flange on one side the opposite flange will rotate in the same direction, however an open diff will rotate in an opposite direction.
I wish I had one on my 2+2!
cheers Jon

Additionally I have read that if using a 2.0 Zetec in a Fiesta (H4) the standard inlet manifold is the wrong shape/too big and the best one to go for is the RS 1800 manifold, I was wondering how this compares with the RS 2000 manifold in terms of size/shape.
 
Comments welcomed!

Hi Jon,
 
Yep, that is my understanding however a (supposedly more knowledgeable) friend said this isn't always a reliable indicator as sometimes they get sticky?!
 
Plus I have to admit that I can't remember and haven't even been near them in over a year! Will be heading over to the storage unit in the next few days and will have a check, sure there are some other bits I have forgotten. For starters, I fortgot to say that the Specialised engine was removed from a MK3 show Fiesta so is essentially ready to drop in to a Quantum, has a yellow painted block and has red Piper timing vernier pulleys that are also over £200 new.

If there are no driveshaft joints fitted you can also just look through the hole in the gearbox.
If theres a driveshaft sized hole right through with the smaller diff shaft crossing it at right angles then it’s an ordinary diff.
If theres only about 10mm dia hole through then it’s a Ford LSD
 
I don’t know what aftermarket diffs look like though.
