Where can I get an induction kit for my 1.1 carb?
There is no induction “kit†available for 1.1 carb. Try the carb bolt-on filter from K&N.
It will not give you any power increase, but will make the car louder… and possibly poorer running in cold.
My HCS engine Fiesta is very noisy!
You need to adjust the tappets, where the procedures can be found in the Haynes manual. (check Valve Clearance Adjustment)
What is a ZVH engine?
It is a CVH engine (probably with a turbo) with Zetec 2.0L bottom end, so that the car can keep the modified head while having a bigger capacity and stronger bottom end.
What is the most cost effective way of getting more power for my Si 1.6?
There is little point tuning the 1.6 Zetec, as the head is very restrictive.
The most cost effective way would be putting a Zetec 2.0L engine in. It is straight in without too many things to change.
Notice that you CAN use the 1.6 ECU, but it will under-fuel at high rev range.
Refer to the next question for more info.
Can I put a Zetec 2.0L engine into my Fiesta?
Yes. Notice that the Zetec 2.0L engine can be found in Mondeo, which is apparently quite popular and quite easy to find. A complete 2.0 engine can be bought privately for as little as 100 pounds, or around 400 pounds from trade for an average mileage one with warranty.
The 2.0 engine produces around 130bhp which is quite nice for a small and light car like a Fiesta.
See the guides Section for more info.
Contrary to common belief, the insurance is not as scary as thought to be.
Certain insurance companies, like HIC, consider a 2.0L powered Fiesta Si to be of group 9 insurance (i.e. same as a 2.0 Mondeo). But of course, the final quote depends on many things.
Can I put a Cosworth engine into my Fiesta?
Nothing is impossible providing enough time and money are given. But the costs would probably exceed the expectation of common people. Rumours are that it would cost over 10k pounds, which is quite believable.
Just bear in mind that a Fiesta and a Cosworth are two completely different cars.
How do I get 130ps from my 1800cc 16v XR2i?
You need to get the throttle body, MAF sensor, camshafts, and ECU from a RS1800 or a Mondeo Mk1 2.0.
Notice that although the diameters of RS1800 throttle body and Mondeo 2.0 throttle body are pretty much the same, it is easier to fit the RS1800 item due to the mountings.
What are the more “advanced†tuning routes for my Zetec engine?
- Turbocharging
A very complex topic in itself, but all the most powerful Fiesta in this country are running Zetec Turbo. Basically there are two ways of doing it, the proper way and the budget way.
Proper way: Forged pistons and aftermarket management system (such as Pectal), and have it built by Ian Howell! There is no set cost for this – the sky is your limit.
Budget way: Spacer plate and FRST management system, with ERST turbo unit and exhaust manifold, notice that the 1.8L engine has stronger pistons and smaller bores than the 2.0L engine, hence is more suitable for this application. But it is VERY unsafe to run over 1bar (14.7psi) on this setup. 8psi recommended. This budget turbocharging can be done for as little as 1000 pounds.
- Supercharging
I got a quote from Autocraft SVE http://www.autocraftsve.co.uk for 3,650.00GBP for a supercharger (ProCharger from the US) supplied and fitted to a 1.8L Zetec with dyno run before and after, with expected power gain of 50%.
I personally have no experience (nor have I heard of anyone has) with this company, so I can’t comment on it any further.
- Throttle Bodies
Throttle bodies kit can be bought from 1700 to 2500, where the most popular choice seems to be Webber Alpha kit (including inlet manifold, throttle bodies, fuel rail, injectors, management, linkage, etc).
Compared to turbocharging or supercharging, the installation is relatively easier. Labour for fitting and mapping should be around 400 to 700.
It would give 30bhp power increase on average. Fuel consumption is not very good, but is better than twin carb anyway.
What brake setups can I fit to my Fiesta?
- Cosworth 4×4 or Granada V6 Cosworth (Mk3)
These are single-pot, 278mm setup.
They go straight on with some spacers/washers, and drilling (enlarging) the mounting hole from 10mm to 12mm.
Notice that Cosworth 2wd brakes WOULD NOT fit due to different offset.
By “Cosworth 4×4″, I mean Escort Cosworth 4×4 and Sierra Cosworth 4×4.
Minimum wheel size is 15″, but still they might not fit depending on the design of the wheels, so 16″ recommended.
- Mondeo V6 (Mk1 and Mk2) or Scorpio V6 Cosworth
These are single-pot, 278mm setup. The Cosworth 4×4 and Mondeo V6 calipers, discs and pads are very very similar.
They go (pretty much) straight-on when the carriers are machined 3mm or 4mm off the surface, or if you are brave you can space the discs out by 3 or 4mm. Drilling (enlarging) the mounting hole from 10mm to 12mm is also required.
Apparently Mondeo V6 brakes are cheaper and easier to find than Cosworth ones.
However, Ford “economically†fitted some 260mm setups to some of the V6’s. So make 100% sure when you buy second hand.
Minimum wheel size is 15″, but still they might not fit depending on the design of the wheels, so 16″ recommended.
- Focus ST170
These are single-pot, 300mm setup. Apparently these are monsters and very very good at stopping.
They go straight on with drilling (enlarging) the mounting hole from 10mm to 12mm.
They usually can be found on various Ford forums for around 300 pounds.
Minimum wheel size is 16″.
- Escort RS2000 (Mk5, Mk5b, Mk6)
These are single-pot, 260mm setup.
They go straight on without any modifications.
Minimum wheel size is 14″.
- Fiesta ST150
These are single-pot, 278mm setup.
They go straight on with drilling (enlarging) the mounting hole from 10mm to 12mm.
Minimum wheel size is 15″, but still they might not fit depending on the design of the wheels, so 16″ recommended.
These are quite rare at the moment because the ST150 isn’t even for sale yet!
And of course, many aftermarket setups from Godspeed, Hi-spec, Wilwood, Brembo, Tar-ox, etc…
How do I bleed the brakes?
See the guides section..
Do I need a FSE Power Boost Valve?
The Fiesta RS Turbo and 8v XR2i already have adjustable fuel pressure regulators.
So the “Power†Boost Valves are pointless – moreover they must be set up on a rolling road to work properly. Can be worthwhile on a Zetec with the right modifcations.
How do I upgrade my turbo from T2 to T3?
