Our Modification Direction

 

T

here are several major ways to modify a car – any Ka – and this all depends on (a) what you have, (b) what you want, and (c) how much you want to spend doing it.

If there’s one thing that has underscored what Charlie and I have done to Kermit, it’s been that we’ve kept in touch with our real world use of the Ka.  Kermit’s annual mileage, excluding extended road trips, is approximately thirty thousand miles a year.  We don’t want a ride so hard we lose fillings, wheels so big that tyres are very expensive and an exhaust so loud we still hear it ringing after an hour of not being in him!  Kermit is first and foremost a means of transport and at the time of writing, our only car.  For that, he needs to be reliable, economical, comfortable, and inexpensive to run.

Originally, we decided to sharpen up his appearance rather than redesign Ford’s work.  Our plan was that when we were done, we wanted Kermit to look like any other Ka to the untrained eye, but for the more observant, they will notice the subtle differences.  So we went down the route of the light brows, the smoked rear lights and the Orciari rear spoiler, to name a few modifications.

We were not originally planning to make any modifications to the engine, nor to the exhaust, but after extensive research, I’ve decided to make a number of small changes to the engine.  It started with the K & N replacement panel filter, then a Janspeed back box, upgraded to a PowerFlow full exhaust system, the Superchips Bluefin ECU upgrade.

Our original plan also called for sticking with the original Ka alloys, suspension, brakes and transmission, but that changed somewhat!

The 2004 Update

In May 2004, our modification direction took a change.  Whereas up until this point, we had been researching and making modifications so as to enhance Kermit’s looks - more like customisation rather than modification really - and we had secured the Ford Racing Suspension Kit, our necessary annual mileage jumped up from four thousand to twenty four thousand.  This had a dramatic influence on our car running costs.

We upgraded his exhaust by replacing the Janspeed back box with a PowerFlow system.  The PowerFlow features a twin outlet on the one side and isn’t too noisy.  At a moderate cruise he burbles along, increasing to a booming roar under heavy load with a burble at idle.  On the overrun, there’s the occasional pop and burble if you listen hard enough.

You can find a discussion concerning ways and means of reducing Kermit’s running costs here, and these are all associated with petrol.  In this document, you’ll find references to the idea of converting Kermit to run on diesel (the Ka TDCi or the Ka XUD), having Kermy running on LPG, and a few other ideas besides.  I had explored some of these ideas before Charlie and I had even thought of living some distance from our workplace, such as the taller final drive ratio, and some of the ideas had been previously dismissed.  One such idea is that of using the Ecotek CB26P device, which the makers claim improves performance, emissions and fuel consumption all in one, but is inexpensive to buy and very easy to fit.  You can read my experiences of the Ecotek device here.

I wanted to sharpen up Kermit’s dynamics a little with a wider front and rear track and slightly wider tyres.  I’d tried various Kas running on 15” alloy wheels wearing 195/45 profile tyres and whilst I enjoyed the improved levels of grip and traction, I wasn’t especially happy with the rough ride and snappy handling.  It was too great a compromise for me, so I sought an alternative.  195/50 tyres on a 14” rim would work and many mark four Fiestas use a suitable alloy, but getting hold of a wheel in Ford fitment with an offset of around 30 to 32 was a pain.  In the end I opted for XR2i 13” alloys that have the right offset, there’s plenty of tyre choice and as it happens, the balance of ride and handling is just what I wanted.

For the headlamps, I was using Kermit a lot more at night down twisty country lanes and wanted to improve his illumination.  Morette’s triple headlamp conversion provided the answer!

The strut brace went on Kermy in late 2004 ready for the Ford Racing Suspension upgrade.  In isolation, the brace improves things when pressing on, especially in the dry, but it increases body roll (there is less slack taken up by the chassis so the suspension has to work harder).

2005 And Beyond

In early 2005, Kermit benefited from a few upgrades.  One, the Ford Racing Suspension, sharpened up his dynamics.  He now sits lower, corners flatter and has much reduced nose drop under braking.  There’s very little detrimental impact on the ride except under certain circumstances.  Charging along the Italian autostrada at a GPS-verified 125 km/h can be a little rougher because the road surface isn’t always the smoothest!

The second major upgrade is the addition of electronic cruise control.  This is one of the most expensive upgrades we have performed to Kermit but it gets daily use during my commute to and from work.  It has also proven invaluable in improving (reducing) his fuel consumption.  Not so much because using it saves fuel, but because when I’m using it during my commute I’m less likely to charge off after somebody who has upset me!

We then proved how useful Kermit would be on a long haul trip by driving to and from Italy in him!

What’s to follow?  I can’t say.  I’d like to report that we’ve finished but there’s always the possibility I’ll find some nice 14” wheels in Ford fitment but with an offset of 30.  And I may also find a decent fog lamp solution too.

Planning

I’m often emailed with requests wanting further information about what to do with modifications, and the best bit of advice I can give is to plan.

Planning, planning planning, it’s all about planning.  If you plan a project, it tends to work much better!
