yeh , I phoned them - need to order about 5 sets or so ! - I'm waiting for a set for my 1400 ,getting them through the Uk Catcams dealer .
I've also ordered some rods from another supplier that uses 3/8" rod bolts rather that 5/16" , I had to order 2 sets though . My project is slowly coming together -just collecting the parts just now.
Surely not alot of folk doing much with the zetec se just now ?,,it all seems very quiet

Glad to see you backat yours . Hope to put mine on the rollers in a couple of weeks or so.
I have too many other "projects" that seem to take over ! ,,,,doesn't help that the Misses has a rally car that has to be worked on !!
,,and it also doesn't help when the engine builder throws another idea at you today,,I'm waiting to see how much his idea is going to cost me - might put my 1400 zetec stuff back on the market ! The Ka has been off the road since April 09
I re-built our old rally car(AX) and took it out for a few events last year and the wife used it when her 106 clutch started slipping when it was on the rollers getting mapped the day before we were due to be leaving to go to an event . I've now got a guy wanting to buy the Ax which will mean one less car to distract me .
-Watch this space !
I work In the hot test area at Bridgend Ford and with regards the new GTDI turbo engine I can tell you that apart from the actual footprint of the engine It has very little In common with the sigma It replaces..
The head Is totally different and the pistons could not be retro fitted to a current Sigma and judging by the amount of sensors and connectors we have to connect before we can start them I would say that It would be a right headache retro fitting one to an escort etc
interesting you're working on the GTDI.......
the sigma is still in production and will be for quite some time, definately an interesting retro fit engine.
http://itsalmosttime.co.uk/blog/
Yes the normal sigma Will run for a while yet the new gtdi would be a fair challenge to retro fit theres sensors everywhere lol no doubt someone will do it though?
Isn't the 1.6 Zetec se pretty much done? No car in production today has that enigne anymore? only 1.25 and 1.4 variants available. Only the Ti-VCT is available in 1.6.
I believe the Fusion and the Focus II were the last cars with the 1.6 Sigma engine. Here in Finland anyway.
The engine itself will propably still be in production for a while though.
I think they are due to run for a few years yet as the 1.25 and 1.4 sell well In the fiesta and the 1.6 vct I believe goes In the lower spec focus with the gtdi going In the higher end cars?
I`m already planning Stage 2 as well
I have a spare 1600 bottom end and a spare Head, so stage 2 will be forged pistons, maybe steel rods
And now that I am working at Active Technologies, a set of AT power Direct to head shaftless throttle bodies
Still all in conjunction with the supercharger too
I have a set of AT power DTH throttle bodies now so I'm going to run mine NA to start with.
AT are also doing a billet dry sump kit now too, i should be getting a dual scavenge pump built shortly as a bit of a prototype.
I'll update with pics once my bodies are back from anodising
Does any one have any exhaust primary length info too as I need to get a rwd block hugging manifold done too
cheers

Hi I'm looking to put a puma engine into my mk2, looking for a clutch, pressure plate and bellhousing for a type 9, can you quote me please? Thanks wyn
I do not know how to pull that off with the STD flywheel but you should talk to Jon at Shawspeed.
If you are using a flywheel for a 184mm clutch there should be plenty of options for you
Hi guys, I am building a Roadster based on the Haynes book by Chris Gibbs. I am planning of installing a Zetec Se 1.6 with twin independent variable valve timing since the local authorities do not allow me to use the 711M motor. Do any you guys know which programmable ECU's can handle the variable valve timing? Or possibly how to control the valve timing through an external module such as Arduino.
Bertu fro Malta the sunny island.
old thread but an interesting read , i an getting a SE engine built to replace the old CVH in my fiesta race car , looking forward to getting it and having a more competative car , but quite a minefield for parts and advice ect as it has so many guises , sigma ,zetec se ,ect as in essence its a mini duratec
Very interesting .never thought of doing this engine up.could make sense
Hi,
A friend of mine is turbocharging his Fiesta Mk7.5.
It is a 1.6 Ti-VCT sigma! We are trying to find some forged internals but it seem's almost impossible to get anything for this engine.
The internals are the same as the Zetec 1.6? I can retrofit some zetec 1.6 forged pistons and rods into this Sigma?
What about the Ecoboost 1.6? The internals are the same or different from the sigma 1.6 tivct?
Thanks in advance.
totally different engines im afraidThe internals are the same as the Zetec 1.6? I can retrofit some zetec 1.6 forged pistons and rods into this Sigma?
I can supply forged rods and pistons for the 1.6 Ti-VCT engine
Browsed through the whole thread looking for numbers and specs for the smaller versions of SE, 1.25 and 1.4.
They seem not so common as the larger version.
Are there cams, springs, etc. also available for these smaller ones?
I'm still comparing engines for a circuit racing project Escort mk2
Could the 1.4 be a candidate for a car with ~900kg?
I have put details of my Triumph Motorcycle (2001 RS Sprint Triple) Throttle Body setup on the 1.7 Puma Zetec SE Engine in the link below if anyone is interested.

1968 Ford Anglia 1.7 Puma engine/Escort front/5 Link rear/RX8 box
http://www.Anglia1968.weebly.com
Me and my dad have been working on these lumps for a while and are having a lot of probs sourcing a 79mm piston with comp height of 25mm and pin size of 19mm.
Anyone help out please? We don't want to go drilli g a 1600 piston out from 18 to 19mm
Simon
Can't you use an 18mm bush in the rod instead?
John
Cheers Shawspeed, source a 19mm pin wouldnt be an issue as well as sourcing 18mm pins.
The problem is the rods.
Just for info purposes the 1.25, 1.4 and 1.6 all use the same Crankshaft main bearing set. (cranks swappable wall all blocks? That ill find out)
1.25 Big end size: 40mm with shells 43mm without?
1.4 Big end size: 40mm with shells 43mm without?
1.6 Big end size: 44mm with shells 47mm without?
1.25 Conrod Length: 134mm approx.
1.4 Conrod Length: 134mm approx.
1.6 Conrod Length: 138mm (137mm after market pec)
The Mysterious 80mm 1.4 piston: Piston diameter, class 3 (1.25l up to 13.10.96 and 1.4l) mm 71.895 - 71.905 75.995 - 80.005 78.975 - 78.985 (taken from ford data).
So again, finding a rod with big end of 43mm, 19min pin, bore 79mm comp height 25.025 is proving to be on the verge of imposible - but I've love to know what fords escosport N/A 1.5 lump uses seeing as its 79x76.5 in spec.
1.7 also uses the same main bearing set. Finding a std rod with that spec is highly unlikely. I think you will be looking at getting a custom set of rods manufactured.
Apologies for digging up an old thread, it's just there's very little info out there regarding the Sigma engines.
So in the interest of keeping things in one place.. I would like to add a few questions if anyone has any input/knowledge they could share
* What are the different generation of Sigma engine? I hear of silver top, black top.. Would like to understand the differences, other than a cam cover. I suspect the cranks may be different from what i've seen.
* Trying to find out specs of OEM 1.4 and 1.6 rods and pistons, c-c, big-end, small-end, etc.
I've measured a 1.4 and 1.6 crank shaft, and whilst I believe the majority of the dims are identical, the big end is unfortunately smaller on the 1.4 crank (40mm vs 44mm).
Unfortunate because I had built up some fantasy de-stroked 1.6 engine, using a 1.4 crank and Vauxhall pistons. Doesn't look like that's going to happen unless I get custom rods.
I've heard lots of stories about the 1.6 engine, e.g. fine to rev to 8500 with just ARP b/e bolts.. I wonder what the standard rods are good for in turbocharged usage? I see Accralite do a turbo piston - i'd be very interested to learn what kind of CR they come up at on a standard engine.. basic calcs are showing the CR to be IRO 9.5:1 - 10:1. which is too high for me.
cant help with most of your queries. but i thought silver and black top references refered to its bigger brother the zetec.
rods in turbo engine will actually stand more rpm than in na applications, but the beauty with turbos is you dont need loads of revs
Yeah I know what you mean Graham about rods.
It appears the Sigma engine also got called silver and black top - earlier engines seem to have used an aluminium cam cover, much the same as the Zetec-E engine did before 1998.
Perhaps the earlier sigma was used in the Mk5 Fiesta, not sure about the Focus.
Info Here...... http://www.burtonpower.com/tuning-gu...ing-guide.html
Also I believe that the crank nose does not have a drilling to take a spigot bearing so complicating use in a RWD car.
My application isn't rwd so no worries there.
As far as I know the 1.25, 1.4 and 1.6 Zetec SE have the standard 22mm cavity to take a stock Sierra bearing but the Puma 1.7 does not, think this is 17mm of the top of my head so either needs boring out or the gearbox input shaft needs grinding pig dien, think retro ford sell smaller bearings.

Sorry to resurrect the thread but through I'd try and keep it tidy with info on this engine in one place.
So, Zetec SE coolant pipes Questions -
Please can anyone confirm that I have this correct ?
For use without a heater
1) Small outlet on the thermostat housing on the block > manifold on the rear (using original hose with restricter in it), note I have a replacement shawspeed manifold on the rear to help bulkhead clearance.
2) Large outlet on the thermostat housing on the block > bottom of the radiator (using VW polo one) (hot feed?)
3) Manifold on rear of engine > radiator top hose (cold feed?)
4) small pipe on rear of engine to header tank
5) T in pipe 2) above to bottom of header tank
Things to confirm - are 2 and 3 the right way round and which pipe is the connection to the header tank in (assume 3 above)
With a heater (classic mini one) just put it in pipe 1, happy for it to flow through all the time rather than add a bypass valve.
Can anyone confirm whether the water pump pushes or sucks water through the block i.e. hot water out at thermostat or at rear manifold block?
Thanks in advance for comments/answers.

New member's first post. This is a really interesting and informative thread.
I have a 1966 Ford Cortina Mk1 that a previous owner modified with a GM 4.3l V6, T56 transmission and Ford 8-inch rear end.
I'm doing a coil-over + rack-and-pinion conversion and am keen to replace the V6 lump with a 1.6l Ecoboost, which I think is somewhat similar to a Zetec SE? The 1.6l Ecoboost was used on the Fiesta ST, which apparently is commonly crashed in the U.S. as used, low mileage engines are readily available.
I'm particularly keen to talk to ugg10 as he installed a Zetec SE into a Ford Anglia and has likely worked through a bunch of pitfalls I would just as soon avoid.
