mk5 fiesta zetec s tuning,whats the best way to go?
Got a totally standard zetec s mk5, I want to make it faster but what are my options and which is best? puma engine,turbo, 2.0 zetec/duratec or tune the original 1.6?
I want maximum power and want to pay next to nothing for it!
here it is on the nurburgring last weekend, no 8 min lap times for me
I was thinking a standard st170 lump would be plenty powerful enough for what I want in a mk5 fiesta!
I'm only looking for around 150 ish tbh.
how easy is a zetec/st170 engine to fit in mk5?

I thought my old ST170 went well for what it was.
I think a 4 branch manifold makes the 1.6 engines breath better.
The puma conversion is probably the easiest engine swap cause its just a plug and play type of conversion.
When i had my puma. I fitted a mondeo 2ltr throttle body and bored the inlet manifold out so it would work. I also fitted a cone filter with a good cold air intake.
I got beat by a standard puma one day on the way to work lol.
One of the best handling mods i did was fit rear wheels/axle spacers and bottom strut/sub frame brace.
Also i used mk3 mondeo calipers and st170 brake discs. This conversion cost me about 80 quid all in. They were defo a good upgrade compared to standard. I had to grind the calipers a bit to fit behind the standard 15s.

that's interesting, did you just do the fronts or did you swap the rear drums for discs? Why did you mix and match, why not Mondeo calipers and disks or st170 calipers and disks?

I just changed the front brakes.
Mondeo mk3 calipers were alot cheaper than st170 calipers at the time.
IMO it's a lot of work to put a zetec, turbo'd or not into a mk5 Fiesta. You need a lot of custom parts, especially if using an MTX75 gearbox.
As for brakes ST170 callipers will work on the front, just need to enlarge the holes on the hub to take M12 bolts. The rear disc conversion isn't too difficult either. A little more tricky if you want to retain ABS as you need to get the Tone rings from the drums machines onto the back of the stub axles.
I have a few well maintained low miles 170 complete engines if you go that route and can supply any other parts you need for the 170 inc brakes.ecu.looms,bike carbs etc
4-2-1 manifold and decent exhaust, panel filter and shawspeed ss4 cams, stiffer valve springs, updated rod bolts and a remap with a raised rev limit. 150 on the standard inlet is more than do-able.
For cheapest it MAY be cobbling a st170 engine in but by the time you've sorted the exhaust and sorted the loom etc it may be similar price as I doubt you can use the st170 ecu.
Impressive. Whats the cost of these engines and what engine management do people use.
Engine is the cheap bit, the engine management is not.
A local dealer was knocking out engines with around 15k on them for around Ł800 or a full package with box and everything with as little as 9k for Ł1600.
Last year when I looked pre programmed ford racing management was around another Ł1600.
It depends on how deep your pockets are
There are hard to map and need a good Ecu so
I am told
For instance sbd is doing a loom/Ecu kit for 3k
Which is plug and play 300hp
So for time and effort it saves that ain't bad
But it is a lot to shell out in one go
But once you have gone balls deep on a pukka
Zetec turbo build plus Ecu it would probably
Be cheaper and quicker
These engines are going to get very popular
As they are light and have good power so as time goes
On the Ecu convertion should become affordable to most
Good idea but that's alot more than I want to spend. I paid less than Ł500 for the whole car. I want to do it on the cheap for a bit of fun.
Thoughts on the puma 1.7 conversion?
I like the st170 engine but after some research I fear fitting that could be beyond my capability. Also it could totally ruin the handling which is all the mk5 has going for it.
Well like said the 1.7 engine is just plug and play. Fast Ford mag did a feature on fitting a puma engine to a fiesta. I dont know if its still on the ff web site but it used to be.
I think a 4 branch manifold can be had for about 150 quid. This will defo free up the engine.
What power is the 1.6?? The 1.7s are about 125bhp. Mine used to keep up with ST170s in first and second gear.
I did my puma on the cheap too. I bought a set of cheapy bucket seats for 100 quid then won a complete interior for 10 quid. I used the front seat mounts and bolted them to some strips of metal then bolted the bucket seats to the metal.

Supposed to be 100bhp, puma conversion seem to be best value for money
The puma engine is essentially the same as the 1.6 with a rudimentary VCT. You still have to then piss around with the loom/ecu
Better off spending what you spend swapping the puma in on the 1.6 its-self. Have a look in the kit car world for inspiration, you dont get many 1.7 puma engines there.......hundreds of 1.6's tho
Cams, zaust, manifold and map will see you well above a puma engine.........remember the standard inlet is not restrictive till above 150bhp as LOTS of folk get hung up on FRP inlets etc and all sorts of nonsense with bigger throttle parts etc.
A ST150 engine is a good shout as it goes with the gearbox but again you have to piss with the loom/ecu

This guy is speaking sense.
The best thing about the Fiesta Zetec-S and the Puma are the light, zingy engines. I would never throw a lump of cast iron in the front of one, it just defeats the point of it.
It all depends on budget really. Years ago, a lad I know put a 1.7 Puma engine into his Fiesta and I thought it went pretty well for what it was but, changing the engine is a lot of hassle and finding a low miler might be tough. With all the faffs of re-wiring etc, I think I would just chuck some money at the 1.6. Keep an eye out for used exhaust manifolds etc then, as above, cams and a spot of mapping. If I was putting a different engine into one of these now, it would be a 2.0 Duratec. Alloy block so retains the light weight approach and tuning potential beyond belief. But again, it's still hassle considering what the car cost you.
Best way to make it better would be weight reduction, but it depends what you use the car for. Low weight, big brakes, suspension tweaks and sticky tyres, that's where it's at. It's far more fun passing cars because you can brake later and carry more speed through corners than just blasting past on the straights, waving your wallet at them. A friend of mine has a 1.7 Puma that he's gutted and it's a right laugh. Did a track day with a lad in a 300bhp Astra VXR and the Puma was miles faster for most of the lap. The Astra walked away on the straight but the Puma was instantly right behind it again as soon as it got to a corner.
Remember...
"Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere."
"Simplify, then add lightness."
...and all that jazz.

SS4 cams, Vernier pulleys, 1.7 inlet manifold & TB, 4-2-1 manifold with a sportscat fitted bolted to the standard exhaust, uprated big end bolts, HD valve springs, ST170 air snorkle, Focus Automatic air deflector with a panel filter and she made a little over 150bhp and would rev to 7750rpm (had to fit an ST170 instrument cluster).
She ran like that for around 30k before the bottom end went but I fully expect that was more to do with the 75k of start/stop district nurse driving my Mother did from new going 2 to 3 years without changing the oil. However, it could have been due to me still running the standard specification Ford oil. If I had another I'd probably run M1/Castrol Edge 0w40 A3/B4. After it started knocking I put the engine back to standard, stuck a 10w60 oil in it and done another 15k in it before I sold it!

As massivewangers said. When i did a trackday in my puma i was on cars back bumpers through the corners but as soon as i was on the straight the cars would pull away from me.
Does the 280mm Mondeo V6 stuff fit? From a MK1/2 Mondeo. I think it's much the same as 4WD Cosworth stuff. I had those on an old MK4 Escort once, it stopped pretty well. The 300mm ones are good, but I think you would have to shave them to get them under 15s.
I just did mine on the cheap matey. I only took a bit of the calipers and carriers. If i thought it was very dodgey i wouldnt of done it.
That's fair enough, I wasn't knocking it. Not being in the trade myself I don't know if I would have the confidence in it after Ive done something like that.
thanks for links and pictures you've put up it's been helpful and now I know what I can do with the brakes.
