What performance modifications have you done to your Fiesta ST, and what have you got out of it?

Although this is looking like my next purchase, the Clio 182 is still tempting because it's faster at standard. I do however prefer the looks of the ST and without a doubt the interior.
 
After being on the fiestastoc forum for a number of years, my thoughts are that you should go for an exhaust system, induction kit and dreamscience. These will see you around 170-180bhp with about 150ish lb/ft torque.

Of course if you have deep pockets the world's your oyster, superchargers, turbos, ITBs etc, but then if you have deep pockets you won't be driving a fiesta st. Plus there is questionable reliablility issues with things such as the superchargers with the tuners supplying them not letting on as much as they should through fear of impacting on sales imo..
 
I don't see the point in going down the route of Turbos/Superchargers etc, I would rather spend more money on a different car or the insurance.

Any idea how much the basics cost then? Exchaust system/Induction Kit/Dreamscience remap?
 
All the induction kits seem much of a muchness so most go for a K&N which is about £80 for a new one I think.

Exhausts are around £700+ for a full system (manifold, sports cat, cat back)

Dreamscience is £450 for a new one with several generic maps, but is possible to get custom maps for them too.

There is also the official route of having the Mountune kits which definitely seem worth it if the car is still under warranty..but they are a bit more expensive. Think it's about £1400 for the 165 kit (which is actually a k&n, exhaust and a map) and the 185 kit £1800 (the same plus cams - can be added at a later date also).

You can also try and get it all done on the cheap and use second hand bits, most second hand exhaust systems (piper, miltek etc) go for about £400, second hand DS units about £350 and K&Ns £40, so if you get lucky you can get all those bits for about £800 I'd say, possibly even less if you get a good bargain.

On my st i have:
Full Miltek system, cosworth cams and stage 2 supercharger and it made 254bhp on jamsports rollers. The car is suprisingly quick now, which is why i like it - it catches people out. The car doesnt really wheel spin unless its wet due to the nature of the charger :)

Why did they not do this from the off? The ST150 is slower than it's competition.

The reason they did it was to keep the insurance rating down. It offers ok performance, good handling and looks the part, but isn't really that quick.

They are cheaper to insure than a Clio 1X2 etc and sit in group 13 rather than 16+
 
Yes but the Clio is noticeably faster so it's insurance ratings would be higher.

The insurance is not that high considering what you are driving.

0-60 7 secs and 0-100 17.5 secs. Thats a pretty nippy car for a young male!

£900 ish fully comp insurance on a Clio 172. Just a tad lower on a 172 cup.

That's exactly what I just said :S

It is slower so the car can sit in a lower insurance group and potentially be bought by younger people wanting something relatively sporty
 
^True most ST's I have seen go for about 7k+ for ones in good nick and mileage between 15k -30k.

I am considering getting an ST next year but really, the zetec sport is only a group 6? for insurance, is there even much difference? interior is alike, body kit is alike, just the engine size 1.6 and 2.0.


Also another question what's the petrol consumption on the ST? on average what kind of mpg are you looking at? & also road tax? Also with the mods, I've seen people put turbo's in the ST. Worth it?

Question for "degen" how much have all your mods cost? in total because 254bhp is very good tbh, considering you get them at what 150bhp?
 
A 182 with 15k-30k do not cost £4500, that's a poor comparison.

There is quite a big difference between the ST and the Fiesta-S, over 50% more BHP for a start.

When I checked previously there was around £600-£700 difference insuring a Clio and a Fiesta ST.

Either way, that's not what this thread is about.

I'm curious to see what sort of performance people have got from an ST with some relatively inexpensive mods, as I do think they are better looking (inside and out) than the 182.

However, i'm still not entirely decdied on which I will go for.

Yeah I said the engine, but aside from the engine? what else? Im not a mechanic so that may seem a noob question.

Also clio = french :p so ST wins ;). (im joking before people give me abuse:cool:)
 
Well the Focus ST170 that I've got is exactly the same basic engine, just with polished ports etc and a different exhaust/ fuel map so 170bhp should be very easily achievable. Actually, does the Fiesta ST have the VVT? I'd be interested in mods for the ST170, don't know if I'd wanna spend too much on it though.

It's not the same at all, the ST170 uses a Zetec based engine and the Fiesta ST uses the newer Duratec HE engine.
 
The ST170 uses a tubular manifold that was hand made. Its too expensive to do the same on the fiesta so they went with a mass production friendly cast one which contributes to the power reduction but meant they could price the car better for the market.
