anything is possible if you have the budget and know how

Get a 4 branch manifold for it and a performance air filter.

Put a 2.0 in it. Best bang for buck

Shawspeed SS4 cams!

Shawspeed are brilliant on the 1.6 Zetec s engine. Costs a lot though and gains will probably not be as noticeable on a heavy car like the focus.

Just sell it and buy a mk5 fiesta Zetec s, I've had one about 160bhp frp powered and it was very quick. My current one is just a standard 1.7 and I love it, after owning it for a year and a half and driving cars like cosworth a and imprezas in between it still impresses me. Done 175k miles and I give it death constantly and never misses a beat I can't justify selling it as I only paid £240 for it lol

I don't want to sound harsh but you'd be better off either swapping to a 2.0 or buying a different car, will cost a lot of money to get any half decent results out or a 1.6 focus.

1600cc silvertop Zetec is utter shite for tuning. Honestly mate, don't fuck about with it just save your modding money and buy a better base car.

The Crocodile Hunter

I always thought the zetec se was supposed to be a good engine to tune?

Oranoco

The Silvertop 1800 and 2 litre engines respond to tuning, the 1600 however just doesn't. Blacktop might be different and the Yamaha derived 1600 Zetec is a quite different lump altogether and also responds to tuning.

The Crocodile Hunter

As far as i know all focus 1600 are the yamaha engine which is in a different league to the 1600 zetec fitted to the early mondeos and mk5/6 escorts.

Oranoco

The OP stated Silvertop though which would make it the same nail fitted to the Mondeo, Escort and Fiesta. Don't think the SE was used in a mk1 Focus. Easy way to tell is pop the bonnet, if you're looking at an inlet manifold you can tune it if you're looking at an exhaust manifold you're fucked.

The Crocodile Hunter

The early 1600 zetec se engines have a silver cover the later ones have a black plastic cover. Im unsure exactly what the difference is between them?

We've had a real late 2001 pre-facelift mk1 for 6 years and thats got the black cover.

Davemurphy007

Do not bother.

All the 1.6's fitted in the Focus were the Yamaha Zetec-SE engine. But there were a few differences between earlier and later ones (including Ford's branding on the cam covers - early's are marked Zetec-S and later Zetec-SE, they are the same family of engine though and NOT the 'Silvertop' Zetec-E found in the Escorts.

Either way you'll end up throwing shitloads of money into a shit engine which has to lug a lardy, heavy (although probably rusting away nicely by now) Focus shell and you'll end up with a Focus that's still slower than a boggy 2.0 litre.

Almost right, although the 1.6 se is certainly not shit and a mildly tuned one will blow a standard 2.0 blacktop into the weeds, very comfortably


Personally I wouldn't bother chasing performance in this car as the money you sink into the engine you could just put into an ST170

The Crocodile Hunter

No way i would say they are a shit engine, however i agree that there is little point in spending the cash on one as you may as well just but something that was quicker to begin with.

black1979

ok thanx guys how much messing around do i have to do to put a bigger lump in something like an st170 or a 2ltr want to keep the body as its got no rust or serious damage but want to make it go better but don't want to start something a come up against a load of unsolvable problems or have to start cutting prices out of the body/chassis

It's Czech Mate

Cheaper to sell it and buy an ST170 already done

Davemurphy007

To change to a 2.0 litre you need pretty much everything in the engine bay switched over.

To change to an ST170 you basically need to transplant an entire ST170 into your shell as everything is different.

Or you go custom ECU and fuelling system which ain't gonna be a cheap option.

I defend my opinion that the 1.6 is a shit engine. It's not bad in the fiestas as they haven't got much weight to pull around but most Fez owners bung the Puma 1.7 engine in - which I'll happily admit is a brilliant little engine. The 1.6 IS shit though despite being related to the 1.7.

It's Czech Mate

Balls. If you rate the 1.7 and not the 1.6 you clearly don't know much about them as they are VERY similar. The 1.6 is torquey too, nice flat curve it's easy to tune and light. The 1.6 will make 150 but on the standard inlet with cams, a full system inc manifold and a map. Rod bolts allow some more peace of mind and a raised Rev limit. The main reason people bung in a 1.7 is because it was cheap and easy as it's already semi tuned compared to the 1.6

Adam-M

Not entirely true, the main reason most fit the 1.7 is because their 1.6 has shat itself. They are well know for big end and head gasket failure. 1.7 is a lot stronger has mls headgasket and coated liners. I've ran mines into the red temperature zone twice and still haven't blown a gasket and that's on 175k miles.

Cheaper to tune aswell I bought frp cams and got it napped for 99 with loads of other small bits and bobs made 160 on sitechs rollers and that cost me less than a grand and was mega reliable.

It's Czech Mate

They're not well known for failure unless abused and run low on oil, and the head gasket and big ends are virtually identically the 1600 on the 1700 so that's bullshit also. They are exactly the same to tune in terms of cost also, what you can do to one you can do to the other and they both respond virtually identically

Many many kit car makers do not use a shit engine

The Crocodile Hunter

We will have to agree to disagree then. Personally i think it is one of the best n/a1600's around, its miles better than the normal zetec e 1600, in another league to a gm ecotec or vag 1600. Have you driven a mk4/5 golf/a3 1600 lately?

Just because a boggo 1600 focus isn't a racing car doesn't mean its shit does it?

This is incorrect, all Focus have the Sigma engine, which is available in two phases and was a brand new engine when the Focus was released.

This is where the Fiesta gets it's name from as it later used the engine. They do respond well to cams and exhaust mod's, there is no point in changing to 2L it's way to much work, different suspension, inlet and exhaust on opposing sides etc, thus you may as well buy one outright, as said.

I think the 1600 Focus is ok, although it does lack bottom end grunt, which I find annoying.

What ever you decide.to do with your Focus don't be wasting your.time.down the marina with the rest of the 1st gear redliner crew.

black1979

looks like im tuning the 1600 then new came exhaust ect will be doing suspension anyway also want to put a brake conversion on an change from drums to discs just take my time an get it to how i want it thanx for the comments peeps
