Hey everyone, I've been craving more power in my little Fezza for some time now, but didnt know what route to take, i thought about a 2.0Ltr Zetec because as far as I'm aware, it's practically the same engine, just a higher capacity? Correct me if im wrong.
Also, would this be much trouble to fit? Or are my expectations of it being a fairly simple swap over correct?
Any help would be much appreciated, or even a link to a thread already with some advice.

Thanks,
Ben.

 

I've just been offered from a friend at work an Rs Turbo engine with gearbox, alternator and everything else, for £200. Would this be possible to fit in?

 

you can fit anything in...A popular one is a 1.7 puma lump, which can be fitted for £600-700 all in by some people. Have a look on www.zsoc.com for more info.

 

hi mate, i've just put a 2.0 into my mk4 fez. 2.0 zetec goes in but you need a fiesta diesel endura box for the starter to fit. Also need a 1.8 flywheel and clutch. You need to fabricate a drivers side mount, but everything else just bolts up.

If you want big power in the future, you need the 2.0 blacktop from a Focus, don't bother with the mondeo silvertop. If your happy for something nippy to drive, a Puma 1.7 engine and gearbox will bolt in with out any thing needing doing. Cheap upgrade for the mk4 is puma 1.7 brakes and suspension too. Get it all cheap off the bay. I went with the 2.0 because I got offered one cheap, but knowing what I know now I would have gone with the 1.7.

The rs turbo engines fit, just need to sort the drivers side mount again and fit the ancillaries. Go with EFi if your doing it mate as the MFi is toss. The RS Turbo box isn't a straight swap, its mountings are different. What a lot of people do is put the diff from a turbo box into a diesel box that has the taller ratios, and then bolt the whole thing in the bay.

If you want 130 - 160bhp go for a 1.7, if you want turbo power built a zetec turbo with a diesel box.

That's a big help Dave, thanks.
I've heard a lot about the Puma engine but they're getting a bit sort after, and prices are a lot more than Zetec's or CVH's.
Also, how would i tell whether its an EFi or MFi?

I'm wanting a good 200-250bhp, so would the CVH be a better option, or the Zetec?

Zetec, for more reliable power...

Puma engines aren't sort after, and they're cheap as chips, to buy and to fit! There's a gent on zsoc offering to supply and fit them for £750....

 

£750?
I can pick a 2.0ltr Zetec up with all anciliries for less than £200, and fit it myself with not a lot of hastle.
Everyone and their brother wants the Puma engine because of the ease of fit, truth be told that it's all well and good, up to 170bhp max, after that you're just wasting money and may of gone with the 2.0ltr.

 

Fit it then! Although, you appear to have gone from asking how they are to fit, to saying you can fit them easily...

 

as said, zetec blacktop will be cheaper to buy, not massive hassle to fit but still messing about.... ( youl need from a 1.6/1.8 escort/fiesta zetec E silvertop: sump, oil pick-up, flywheel/clutch) if using a blacktop then engine mount maybe easier to mod using a mix of fiesta/2.0 focus parts. the exhaust will need modding as its on front. and of course ecu, which i doubt will plug straight in. you would have to check the exact pin location and count first as theres at least 3 variations on mk4/5 fiestas alone.

however, if you want a nippy fiesta that can be easily turned round in a weekend then stick the puma lump straight in. a bit dearer initially like you say due to demand, most places round here want around £600 for the engine alone!!! so £750 supply & fit isnt too sad. but its the ease of the job thats the benefit.

overall, its tricky, both similar power, id say the 2.0 is stronger and cheaper more versatile to modify/tune at a later date ie turbo or throttle bodies or carbs etc. the 1.7 although better than its smaller brothers isnt so forgiving to abuse and requires loads of cash for high power. but it is such a quick, easy and relatively cheap swap if you want a nippy reliable fez.

How about a fiesta ST engine? I think a chap called olly from OC motorsport did this not long ago, nice tidy swap too! just an idea.....

 

An EFI cvh will have electronic fuel injectors and fuel rail. An MFi will have a big chunky fuel metering unit over the gearbox. The EFi is easy to spot cause it has sensors and wiring stuck all over it.

You'll struggle to get a CVH Rs Turbo lump past 200bhp with out spending a lot of cash on it. Easiest way to 200bhp is probably a Z-VH. Building a Zetec Turbo can be done on the cheap for 200bhp, but either way its time and money. I've decided to go the power/weight ratio route by stripping the shell for light weight and using bike throttle bodies and megasquirt. This has been the cheapest budget option for me to around the 150bhp mark. It depends how fast you want to go really.

 

This is my plan with my fiesta, gotta have a chat with ollie when I finally have some money!

 

Duratec swap is big money

 

Okay, here's my current situation;
I have an XR2i sat in the garage, pretty much made up of rust, we've decided to scrap it, but as it has the 1600 cvh efi engine, im wondering whether its worth the effort of putting it in my mk4? As my mk4 is only a 1.25 Zetec, im sure it'd feel somewhat quicker?

 

TBH, for the amount of work it'd take, and the very little gain, don't bother.

 

Ah ok. I'm stuck on what to do then lol

 

Just a quick one guys, i've got hold of a 71k Puma engine for peanuts, and was wondering if i need the loom from the Puma, or if i can just use the one out of my 1.25 Zetec fiesta?
