What are the differences (bar the obvious, ie capacity, pistons etc!) between the 1.6, the 1.8 and the 2.0? Are they all the same size on the outside? or do the 1.6's have smaller blocks etc? What about heads, are the port sizes different, and are they interchangeable between different capacity Zetecs?

My mate has a fiesta zetec S, and he's after about 180-200 BHP out of it for the cheapest outlay possible, I know vaan-aitken used to do a turbo kit for the car, but they are no longer selling it, and we we wondering about making a home-made turbo kit for it, as the 2.0 Zetec seems to be fairly easy to convert

Will a 2.0 Zetec fit into a fiesta without too much hassle? Orcan you bore the 1.6 Zetec to a nigger capacity?

_DAN_

Pretty sure you can make the 1.8's 2.0power with the cams,throttle body and a couple of other bits.

Some good info. http://www.zetecinside.com/xr2/stepbystep.htm

PhilM

The 1.8 and 2.0 Zetec E are very similar, heads can be interchanged etc. The 1.6 has a different head iirc as the bores are a fair bit smaller.

The 1.6 Zetec S engine is totally different altogether though! So dont know where you'd stand with fitting a any of the early/late zetec turbo kits. An obvious difference is on the Zetec S series engines, the intake is at the front, the traditional Zetec engines have the intake at the back.

Mind you, its not that hard to do from scratch really, turbo, manifolds, engine management, injectors, intercooler etc.

use a s3 zetec should bolt straight in , and turboin one with just a de-comp plate t3 15psi and all the other odds and ends should make over 200bhp

RWD_cossie_wil

I was just thinking in terms of "bolt on" bits for the turbo conversion, as most bits for the 2.0 are off the shelf parts now.

How different is the Zetec S engine then? I don't really know much about them, what sort of power would that take do you recon, with say just low comp pistons? T25/T3 make 200BHP on a 1.6?

luke89

the 1.6 engine is ment to be strong for what it is , not sure really as i never looked in to them , the s3 engine i said above is a black top and come in 2.0ltr , have seen a turboed z-s pull 198bhp on a RR standered engine and box

the zetec SE engine as found in the fiesta ZS and the early focus is completely different to the zetec E, naimly that the inlet and exhaust manifold are the other way round (inlet being at the front, exhaust being at the back) on the Zetec SE.

If you wish to turbo it, for simplicities sake, transplant a 1.8/2.0 Zetec E, a late Xr2i/RS1800 would be a good donor

PhilM

Yeah, as Luke says, I don't really know much about the Zetec S 1.6 engine.

I'd just get a 2.0 Focus lump as Luke suggested and bolt that in with a T25 or T3, and some management, possibly Megasquirt for a budget project car. Pistons for the Focus Zetec engine are very cheap, Ł500 will get you 8.2:1 pistons with rings, H section steel rods inc ARP rodbolts. Pick a 2.0 engine up for next to nothing these days aswell.....daft not to

PhilM didnt realise how cheap the pistions and rods for the focus are that scraps my idear of using a silver top altho i have a shitty one built up for the time being phil can u tell me were to get them parts from ?

PhilM

They will go in a Mondeo silvertop aswell, if you use both the Focus rods and pistons. (Cant mix focus pistons with mondeo rods).

These are the places I got them from when I last used them;

http://www.focus-central.com/ for the pistons (8.2:1 Forged Pistons with rings) - Their site is down currently!

http://www.newedgeperformance.com/in...PROD&ProdID=43 for the con rods with ARP bolts.

Was just a tad over Ł500 shipped for them both if I recall.

Edit to add another link for the pistons:

will a 1.8/ 2.0 Zetec fit into the bay of a Zetec S easily enough, iedo the mounts all line up? Thats the thing, don't really want to start having to chop and weld engine mounts/ move water pumps/ power steering pumps etc..

OldDan

You need custom mounts, gearbox etc if you're transplanting.

The standard engine (IF it's a Zetec-SE, i.e a black top, not silver, as this has differences in the head, and bottom end) is great engine to tune. Take a look at www.ShawSpeed.com/fsigma.htm

This is the same engine as in the Zetec-S, I've just ordered some SS4 cams, shims, HD big end bolts, so we'll see how it is...

RichieST

iTrader: (2)

You sure? late xr2i/rs1800 mounts should work.

What are the sifferences? I thought they were the same. I have stripped down both a zetec S and a zetec SE, and they appeared to be both the same internally

Why do you need an omex ECU? so ignoring that you might need an ECU swap, basically they are saying with a bit of re-mapping, a set of cams and big end bolts, you can take a 100BHP engine to 170BHP?

I'm sure Stu@MSD could do the software for far less than a new ECU

OldDan

Yep, pretty sure...

Posivitive. They don't recommend repro'd cams with the silver top. They use some sort of washer which is prone to "toppling over" when used with shims. Something like that anyway

Jon @ ShawSpeed also tried fitting a phase 1 crank to a phase 2. It wouldn't fit.

There are minor differences, but the phase 1 (silver top) shouldn't be used with repro'd cams! the phase 2 is fine.

OldDan

You don't, remember these kits are for kit cars, so won't need all the stuff the ford ECU will do.

I've basically bought the 170 kit, but It's been mapped on the standard ecu by Stu@MSD

170bhp in a kit car remember, doesn't have everything a fiesta has running off the engine! It's been said it should be about 155-160bhp on the Fiesta, but tbh I'd be happy with 140bhp!

Revs to 7600rpm too.

RWD_cossie_wil

iTrader: (9)

how much is the 170 kit without the ECU then? Is it worth getting the head ported and polished while you are at it?? The prices they are charging for a lightended flywheel is shocking?!!

Any Ideas on what the torque is like? Does it make it erally revvy and peaky, or does it keep the midrange? And do you need to change the clutch for that power?

OldDan

I've got an uprated clutch..

These are some figures from a kit car with the kit.. (As far as I'm aware they are anyway!!)

I was quoted around Ł320 for cams, bolts, and shims. This is on an exchange basis, for your old cams. You need to make sure that it's the black top engine with ZETEC SE stamped on the rocker cover.

As for ported and polished head, the standard head is good for 190bhp so people say. Not had my stuff fitted yet, got all the bits waiting, should be done for just before FITP.

RPM BHP TQ
3000 63 108
3500 80 120
4000 97 128
4500 109 128

5500 156 149
6000 171 149

cheers Dan, you are a star I think this is what my mate is going to go for, looks great VFM on paper, and not too hard to fit either

Nothing else you can really do to an N/A engine to increase power is there? Have you asked about skimming the head a bit to raise compression?

Mates car is a 02' plated Zetec S, so it's a blacktop

OldDan

Bare in mind, it's probably going to be 140-150bhp on a ZS, but it'll be bloody good fun, especially in a stripped out one

I'm hoping to get it done for under a grand, which is a great alternative to fitting a 125bhp Puma engine at 2k!

RWD_cossie_wil

thats the idea, budget blaster

It's Czech Mate

standard head will flow nearly 200bhp n/a on normal valves so no need for anything other than aquick polish

dan has covered most of it

the zetec-se revision has more float on the crank end bearing and a slightly different valvetrain arrangement, there aren't shim stacks anymore, just top hat washers ground to size. And a few other minor diffs like a second lambda sensor etc

Very underated engine by the ford crowd as they all think its the 1.6 zetec-e usually which IS shit

However the kit car makers know better and have all started using these instead of the k series


pretty shit base for turboing on the cheap tho

OldDan

It's Czech Mate

compression is already 11.1 and some 'tuned' oned pink their tits off anyway so i doubt raising it further is much of a good plan

steved35

i see no one said use a st 170 zetec , are they to expensive to buy ? or dont they fit ??

It's Czech Mate

pain in the arse to put in a mk5 fiesta

steved35

cant be as bad as getting it in a mk2 rs2000 rwd escort

It's Czech Mate

and your point is?



For the cost and hassle of an st170 transplant with a decent gearbox and clutch that works, correct driveshafts and the stupid black oak ecu loom installed alogside ur existing zs loom you could tune the already fitted very good engine to 170 bhp and keep the change

Why reinvent the wheel?

So, with all this talk of being able to use these american imports for the silvertop or blacktop, can you use say the american ARP Cylinder Head Studs? ( http://cgi.ebay.com/ebaymotors/ARP-F...spagenameZWDVW )

Presumablly I would be able to get these from america too ? :
http://cgi.ebay.com/ebaymotors/Ford-...spagenameZWDVW

What other bits could I get from america too ?
