FAQs : Power Upgrades Ford Fiesta

FAQs relating to our Ford Fiesta Mk6 and Ford Fiesta Mk7 performance parts.

1. Does the performance manifold fit easily with a custom cat back exhaust? Does this fit vehicles in the UK?
Yes it does.  Just needs one weld onto your existing system.

2. Just bought a 2002 Ford Focus 1.6 ....98/99bhp approx I think. Saw you do a Stage 1 kit manifold and Unichip. What gain does this give - peak and also midrange?
Yes we do a Stage 1 kit for the Mk6 Fiesta. The Focus has the same engine. The power and torque gains are very impressive. The power increases from 74 kW to 85 kW. And the torque increases by 10 Nm from under 2000 rpm all the way to the limiter. There are big gains from low revs all the way to the limiter. The Focus 1.6 is not that popular here in South Africa for mods. I know the exhaust manifold fits. I think the Focus 1.6 has exactly the same Siemens ECU as the Fiesta mk6. Then the unichip will work fine.

3. Does your Mk6 work on AU delivered Fiestas? Your Stage 1 Performance pack lifts power from 74 to 85 Kw and torque from 145 to 165 Nm. If you add the performance cam to the spec what do you end up with as a total performance package and is this based on 91 RON fuel? Does moving to 95 or 98 RON change this number or are your outputs mapped to 91 RON as per Ford's original spec?
Yes the Fiesta Mk6 in Australia is the same as ours here in SA. It's the European model. We run 95 RON fuel here which is what the power output is based on. You can run on 91 RON that also fine. Or 98 as well. It makes around 94 kW with cams fitted.

Mk7
4. I just want to confirm whether the 4-2-1 Performance Exhaust Manifold will fit on the SEDAN model of the 1.6 Ford Fiesta Mk7 16V.
Yes it will. It's exactly the same floor plan everything just with a boot.

5. I'm looking to do some modifications to my Ford Fiesta 1.6 2010 (mk7) what can I get?
We have the SWR 4-2-1 performance exhaust manifold for your mk7 which really gives good gains in power and torque. Your car has very good performance cams already and you don't need a Unichip as the standard ECU is very good and adapts perfectly.

6. Will still need to install a mini cat and the lambda sensor? Gaskets….standard one at the head (Ford/oem)? Gasket/s for the downpipe joints? Will I need to lag the branches & still need to install a heat shield?
You can fit a cat fooler yes. The lamda sensor screws into that. Don't bother ceramic coating or wrapping. It's not necessary. You can fit a 180mm x 500 round free flow at the rear. It sounds nice and not too loud. You can reuse the steel exhaust gasket at the head. The branch comes with a gasket at the flanges where the primary and secondary pipes join.

7. Does the secondary pipe bolt onto the existing exhaust system or a new exhaust system will need to be fabricated & installed with the round free flow rear box?
The secondary pipe has the spring loaded knuckle attached to it with the flange bolted onto it. The flange has a piece of pipe extending from it and that just needs to be welded onto your existing system. So you keep your existing system. You can first try it with your existing rear silencer and see how it sounds. Many customers are happy with that. Then if you like you can fit a free flow silencer later.

Fiesta Mk7
8. Just purchased your branches for the 1.6 mk7. I'm curious if you'll ever receive any other performance parts for the mk7, such as a camshaft by any chance?
Unfortunately there is nothing more that  one can do to the mk7 Fiesta. It has really good performance cams fitted and the ECU is very good.

9. Interested in the performance manifold for my Ford Fiesta 1.4 97bhp mk7. Was wondering how much bhp and increase this would give? And also how easily would a garage install this? Does it fit easily with custom cat back exhaust?
The SWR manifold will give you around 6-7 kW more power and around 10 Nm more torque from under 2000rpm all the way to the limiter. You can have it fitted at any decent exhaust shop near you. It is a 2-piece manifold which makes fitting much easier. It also includes a quality spring loaded knuckle (flex) and only needs one weld to fit onto your existing exhaust system. Yes it will fit with a custom cat back exhaust.

10. I drive a Ford Fiesta Mk7. Can you give me a list of what you'll have for the following car - 1.4L?
We have the SWR 4-2-1 performance exhaust manifold for your Mk7 1.4. It is very popular. It will give you plenty of extra power and torque from under 2000rpm all the way to the limiter. It can easily be fitted at any reputable exhaust shop.

11. I have a Fiesta mk7 2011 1.6. I was just wondering if you have any performance exhaust manifolds in Stock and please explain the advantages. Thanks.
The SWR branch will give you around 7kw Power gain and 10Nm of extra Torque. From under 20000rpm all the way to the limiter. You will be really impressed.

12. I am looking at purchasing a set of cams for my MK6 Ford Fiesta 1.6 from you. I just would like to find out a little about them. The website says the idle doesn’t change but power increases. What is the duration of the standard cam compared to the SWR cam then? Do I need to chip car straight away or can I do this a little later?
The duration of the standard cams are around 258 deg. The SWR cams are 278 deg. You could fit the cams without a Unichip, but I would advise to map the car nicely for the cams. I would definitely first fit the branch before cams. You lose a bit of low down torque when just fitting cams, but with our SWR branch fitted that sorts all that out and you gain massive torque low down.
