Fireworks At Night

Fireworks At Night

5th November 2009

One of the most prominent aspects of racing and other highly tuned cars is their propensity to disperse copious flames from their exhausts, along with an assortment of pops, bangs, cracks and fizzes. Such behaviour is unsociable, intrusive, legally a grey area but most of all exceptionally appealing.

Your own car need not be borderline WRC spec to produce such effects, indeed some near standard engines are quite capable of such mischievous behaviour with a little encouragement. We'll take a look… Fireworks At Night »

Track Car Preparation

9th November 2008

Track days are becoming increasingly popular as a legal way to push your car and driving skills to the limit. Most track days permit any road cars but as driving on track is a lot different to the road, making…

Zetec Turbo Cooling

22nd February 2006

Note: This article was originally written a few years ago by (I believe) Dave Edwards and StevenRW from the RS Owner's Club Bulletin Board. It was hosted on www.rstcooling.co.uk which now ceases to exist. The article below is an updated…

Zetec Turbo Guide

Zetec Turbo Guide

28th December 2005

Introduction

The Zetec Turbo engine has increased hugely in popularity in recent years and rightly so. With twice the valves of the FRST 1600 CVH and up to a 400cc capacity increase without overbore it offers huge potential. Outputs of over…

Nitrous Oxide Guide

Nitrous Oxide Guide

17th April 2003

Ever since The Fast And the Furious (IMDB), nitrous has been one of the most banded about buzzwords in the modified car scene, with everyone saying they want it, but only a small number of them actually going ahead and getting systems. Nitrous oxide injection is largely misunderstood, with many people believing that they will damage the engine, or the bottles will explode without warning. This is simply not the case, and is explained in more detail later in this…

Zetec Tuning

28th March 2003

Written and re-edited by Adrian, edited by Project. For the introduction and history of the Zetec engine article click here.

Often regarded as difficult to tune, there is still a large number of modifications that can be made to the Zetec engine to increase power, from simple filter and exhaust upgrades to throttle bodies and turbo conversions.

Filters, Exhausts, Cams and Chips

In comparison with the CVH and other earlier Ford engines, the Zetec does not respond particularly well to the usual breathing…

Reliability Issues

Reliability Issues

29th January 2003

A common misconception is that RS Turbos are unreliable cars. This is largely untrue because the reliability of an engine is down to several factors which are often overlooked or ignored with these cars.

As standard the RST engine will last for 150,000 miles plus if looked after. The only problems likely to occur are general wear and tear. Cams usually last about 60,000 miles before replacement and other items such as bearings will need to be renewed as needed. As…

T3 Conversion

T3 Conversion

23rd February 2002

Converting your FRST to a T3 is one of the best ways to increase power and potential power of the car. The larger size of the turbo flows more air and also provides more of a kick than the almost lag-less T2. The T3 provides more mid range than the T2 and maintains boost higher up the rev range than the T2, which has a tendency to tail off above 5500rpm. For serious power the T3 is the only way to…

Fitting 17s

Fitting 17s

27th April 2001

One of the most asked questions regarding Fiesta styling is "Can I fit 17" wheels?". The answer is yes, but there are several things that you will need to do in order to accomodate this size of rim.

1) Modify the arches

The arches on a Fiesta were only made to accommodate the 13" or 14" standard wheels that Ford fitted to the car. If you fit your 17"s straight on they will catch on the arch lip and scrape on the…

Brake Upgrades

Brake Upgrades

20th April 2001

Uprating your brakes is an essential modification to make when increasing the power of your car. Brake upgrades are available in many stages, from aftermarket disc and pads, to full blown 4 pot caliper and large diameter disc conversions. It is also possible to convert the rear drums on a Fiesta to discs.

Uprated discs

The standard setup on all the Fiestas consists of 240mm vented discs and single pot (piston) calipers. This combination is just about enough to stop the standard…

Suspension Modifications

Suspension Modifications

20th April 2001

There are two main reasons for modifying the Fiesta suspension setup. The first is to improve the look of the car, the second is to improve the handling. The reasons you have for lowering the car should dictate the setup you go for, as will your budget. When lowering a car to enhance it's appearance, the object of the exercise is to eliminate the gap between the tyre and the arch. Although the oft used term 'lower is better' is…

Wheels

Wheels

20th April 2001

Note: Before reading this article it should be noted that manufacturing differences and tolerances dictate that fitting advice regarding a certain car may differ slightly from that given.

Fitment information The fitment of an alloy wheel is described as follows: 7x15 4/108 ET35

7x15 is the width and diameter of the rim, expressed in inches. As a guide most 14" rims are 6" wide, most 15" are 7" wide and most 16" and 17" rims are 7-7.5" wide. Certain manufacturers may make…

Tuning the RS Turbo

Tuning the RS Turbo

20th April 2001

The RST is by far the easiest and cheapest Fiesta to tune, and has been around long enough for the majority of Ford tuners to offer upgrade packages and conversions. The engine is almost identical to the 1596cc Compound Valve Hemispherical (CVH) unit found in it's bigger brother, the Escort RST. The main differences are the engine management system, which uses the EEC-IV system also used in the Zetec engine, and the utilization of the smaller Garrett T2 turbocharger. Both…
