I have a MK4 Fiesta 1. (I know it's awful but my BM blew up and it cost me £60) and it's so slow I'd almost say it was dangerous. Is there any way of upping the power a touch (No turbo so not that easy) I'm not after HUGE gains but enough to make merging onto a motorway less pant staining and take off from the lights less dispairing. Can you twin carb these? (I have a pair of webers in the cupboard) Thanks in advance

What effect would a pair of Webers have on a diesel engine??? Maybe you should learn your very basics before thinking of "upping the power" Just a thoughtfull suggestion. Diesels don't work like that

Best keep the webers in the cupboard.

Start with a basic service. Oil, oil filter, fuel filter and especially air filter. Tappet adjustment too if not hydraulic......
Pump up the tyres - every little helps with these! May be possible to turn the fuel up a little but this might just make more smoke without any more power.

Bolt a turbo on! People will say it will blow up and it will, eventually, but it should go well for a while, it'll be a good laugh, and to be honest you should be able to get most of the bits from an Escort TD. Or even just bolt a TD in, with a few boost and fuel tweaks they'll make 110bhp, loads in a Fiesta! Mate of mine did a traveller turbo conversion on a 106 diesel, lasted nearly a year!

Do they haf an air flow meter? My dad's diesel Picasso was slow and I changed the maf and it made a real difference.

I'd say if its that slow, there's something wrong with it (maybe hence why it cost less than a tank of fuel) I drove an Escort 1. van for work years ago and that was not a particularly painful experience..

Well, technically speaking - you can. But it'll contribute nothing to performance at all Actually, many high performance diesel engines do indeed have throttles as emergency shut-off in case of a runaway. I figure you could turn a set of Webers into funky shutoff-valve Giving a good service is fair point - I've looked it up and 60HP/105nm in a relatively light car should be adequate. Don't forgett to inspect the tank strainer, a blocked strainer will also starve the engine of fuel. Or rotten fuel lines (air in fuel) etc. etc. Or; if it was that cheap - sell it with a huge profit and get a Festa 3 with turbo-diezel and play with that (but do some research first - 'cause playing with the wrong bits can ruin a turbocharged engine pretty quick )

I used to drive the turbo charged version for work and always found it painfully slow. It'd do 90 mph downhill and drop to 45 mph going up, quite embarrassing when you've got a set of blue lights flashing on the roof and HGVs are overtaking you. The Police used to be equally disparaging about the performance of their 1.8td Mondeo area cars, my favourite quote being they 'couldn't chase a crisp packet' in one.
That said, you should be able to manage in normal traffic, so a service sounds like a good first move.

Thanks for the replies.
It's got a carb on it so I thought I'd ask about twin carbing it.
The only turbo I have available is a K04s which I think might be a bit much (would be hilarious though.
It probably isn't that slow but when you're used to 3.0 Alfas and such it certainly feels like it.

Diesels don't have carbs.

well mine has something that looks a lot like a carb bolted to the inlet manifold

That would be the injection pump i think , don't fiddle with it !

It won't be a carb mate, air flow isn't really regulated on a diesel, the revs are controlled by how much fuel the injector pump injects, your throttle cable connects to the throttle arm on the pump. The engine just sucks in as much air as it needs, at least in an NA diesel. Pic of this "carb" thing?

It's an interesting point though, well to me at least as the owner of my first dirty diesel - how do you pep up a diesel? On a petrol car you have the options of replacing the carb, different plugs (glowplugs are only used for starting a diesel so shouldn't affect running performance), fuel and air mix tweaking... suppose a performance air filter would still make a difference. If it's a Ford it might have some paving slabs in the boot to improve handling, get rid of those...
