tuning a fiesta zetec s
hi my m8s just got a mk5 fiesta 1.6 zetec s its got a set of cams in it but standard pulleys whats the best way to get more power out this engine ?

The heads flow very well as standard and can be left alone until around 150bhp which can just about be had on standard induction bar a decent filter.
Cams, ITB's, a decent 4-2-1 manifold and system on OMEX or equivelant will see you around 160/170bhp, 200bhp can be had with lairy cams and headwork.

Standard inlet
Decent cams ( really depends on the right grind)
4-2-1
Exhaust
Panel filter
Uprated rod bolts
Remap
150bhp
add throttlebodies and management and uprated valve springs for 170+bhp
the head flows enough for nearly 200bhp as is
the standard pulleys are keyless so they do everything a vernier pulley can in terms of tuning

Puma is fine in mild tune, but at the top end you're only realistically going to see another 10bhp at the most. Waste of time IMO.

Surely got to be worth doing and tuning that than a zetec s? I had a zs when they were fairly new with a k&n and cat back etc and my brother in laws puma zs feels a lot quicker than mine did

Ben
That's probably because your K&N and catback gave you maybe 5bhp if you're lucky lol.

I know I will of had minimal gains I was just pointing out that rather spending the money tuning that you may aswel puma it. I'm sure it only cost my brother in law about Ł400 to puma his which like you said my k&n and cat back was similar money and gave minimal gains whereas going the pula route is more power per Ł

There's no way a 1.6 zetec s engine does 200bhp on a stock bottom end lol
You would need a full race engine to make 200bhp and spend thousands, 160/165bhp is possible with cams, throttle bodies, 4-2-1, full decat system, head work, arp rod bolts
If you think I'm wrong show me proof, people are reading to much into pumaspeed claims,
Full race exhaust and throttle bodies will make around 150bhp so add 10/15bhp max for head work and cams

I honestly don't know how I managed to forget about the bottom end lol.
Burtons did something like 197bhp on standard rods, but it wouldn't last long.
You only need to touch the head if you're going for 170+, they flow fine even at that level.

I'd go Puma route to be honest, got a puma'd mk5 zs myself with cat back & k&n - granted its not the fastest thing on the road but it is bloody quick up to 4th ! I've found tuning is *quite* limited on the 1.7 though, can get FRP inlet, FRP cams, HD Big end bolts & FRP map, 4-2-1, should apparently get to around 150bhp - 160bhp (so i've read)
or if you can get hold of 1, an FRP engine.

Pointless when a 1.6 can be modded for 150bhp on the standard plastic inlet
Cams, rodbolts, exhaust, 4-2-1 and a map...away you go
I've had a few of these done now in various cars and its a piece of cake
These engines are superb, breathing is heavily restricted as standard but the right cams and inlet/exhaust mods will release its potential
Super light too
The right cams are important tho, speak to Shawspeed.
if you want to tune the 1.7 its basically the same engine and you can do the same stuff but its a pain incorporating the vct or removing it so you may as well start with the 1.6
Theres a reason all the kit car companies use them
Best mod to a standard one after the usual exhaust/filter..........retime the exhaust cam or a RR

That's the only pain in the arse for me, VCT ! as I bought my ZS already puma'd there would be no point me going back to a 1.6 I reckon, think I was thinking of my case too much
I guess in the case of the OP, doing all that would be worthwhile I guess, but what kinda cost's are involved ?

A polish helps a little
bodies without cams are a waste of money, the cams are cheaper and can be set up using the existing management, bodies cannot, therefore the cams first is the way to do it (150bhp) then add bodies for over 150bhp, this is where it gets pricey with standalone management required, however ALL n\a cars are 'pricey' to tune and this one gives particularly good results if you're starting from base
also ARP do not make rod bolts for this engine last time I looked
you will also need to think about valve springs if you raise the rev limit much above standard
For the record, Pumaspeed have always been full of shit, Pumabuild are a little better but not massively so.

I was just making it clear that you would not see 200bhp on a stock bottom end, I know about needed management as I would never try fitting bodies without
If I wanted decent future mods I would save my money and fit a 2.0 st150 engine, as cams and bodies with decent exhaust would see 200bhp although it can be done with bolt on mods
And there's all the turbo and supercharger kits out their too

Doesnt need headwork for under 200bhp the valves are plenty big enough

if im honest i would pay too see one make 200bhp on a stock head and bottom end in aspirated form, an st170 struggles to clear 200bhp with throttle bodies and management
i just cant see it happening when i have the experience of having professionals build me worked redtops and aspirated cosworths and the time and money and work needed to clear 200bhp is mental
the small 1.6 would need to have some serious work done to clear 200bhp in n/a form, if it was the case of banging on a throttle bodie kit and cams with forged pistons and steel rods to one of these engines to clear 200bhp then everyone would do it, so what your saying is it doesnt need any porting ect?

Depends what you want to spend.
ZSOC.com has some varied projects.
Anything from a mild engine, upto 300bhp turbo Sigmas in a kit car.
For tuning, ShawSpeed are most popular for the 1.6 and LMS (Lightning Motorsport) for the 1.7.
I'm running 160-170 with a standard bottom end, mild headwork, cams, ITB's and aftermarket management. Rough cost to build mine would be Ł3k to Ł4k.
200bhp is possible, but you will need forged bottom end, headwork and lairy cams, I'd budget another Ł2k at least up from my spec.

I don't think anyone has said it would clear 200bhp with no head work and a standard bottom end?!?!?! Lol in post 5 I said the bottom end needs a mod to safely hit 150

I've seen 190-195 with no headwork other than a polish
Any amount of headwork won't improve this unless you can work out a way of using bigger valves
This is based on having had 5 of these engines in the family in various states of tune over the years, one in a fiesta and four in various kit cars.

Nobody has ever said it would if you read back.
Feel free to carry on guessing what you can do with a sigma, I'm happy to sit here with the knowledge of what I have done.

I'm not sure why you're being so argumentative, you are saying your love to see one doing 200bhp on a standard bottom end and no headwork.

The fact I am stating is that you said the head will flow for 200HP, which is incorrect as it would need work (which you later said, by your own admission) which is the point that Mark made as well.
Tbh, like I say, I seriously doubt that figure anyway, in N/A form.

I'm considering some tuning on my ZS over the next few months so am interested in seeing what your spec is like...

Needs a 16v Xr2i or RS1800 gearbox if you can find one
Again, retime the exhaust cam and thats a lovely conversion IMO as you will have a fairly stock engine and therefore reliability
