I have a 1800cc 16valve mk1 focus.

I want more power and was wondering what sort of bigger injectors will fit my car..

Engine code EYDB

can anyone help me please

its not that easy mate bigger injectors need faster flow fuel pumps which in turn needs a remap which in turn needs the air box removed and either a panel filter or induction kit the list goes on you cant just fit bigger injectors read this maybe youll understand from burton power the zetec e specialists

As far as tuning goes, it’s simple to bring an 1800 up to RS1800 spec with Ford cams or Kent FZ1802 cams - you would need a 130bhp ECU though, or aftermarket re-mapping. A power boost valve will help eliminate the flat spot between 3,300-3,500rpm.

You can actually use the standard injection combined with a new Weber Alpha kit that works with the OE inlet manifold. Fitments are for the silver top 1800s, and both silver and black top 2.0 engines. Power achieved is, approx 150bhp for a 1.8 130PS and 160bhp for the 2.0. However, these are really the limit of the standard induction and further increases are not possible, unlike their other kits. It has to be said that although these kits have been developed for the kit car market, we do not see any reason why they can’t be fitted to a FWD Zetec engined car. Webcon cannot confirm fitment but like us believe it should work. If you want to go beyond the range of the standard induction though, we can supply a Weber Alpha kit, which replaces the system altogether and is incredibly comprehensive - all is there for you to bolt it straight on, including manifold, linkage, even air filters. On an 1800 130PS engine, you should see 155bhp and 165bhp on a 2 litre.

Either of these two systems will provide enough fuelling for plenty of future modifications. Fit one of our stage 1 heads plus a pair of Kent FZ2002 cams and you should see power around 185bhp. If you want to go beyond this ‘Fast Road’ stage then you’ll need our Stage 2 heads which feature larger inlet valves.

The Kent FZ2003 cams will give you between 200-240bhp depending on stage of head, coupled with 48mm throttle bodies. However, at this stage, you’ll need larger followers machined and installed, otherwise the cam lobe won’t be completely ‘seen’ by the follower. We’d also recommend a capacity increase to 2.1 litres, with an 86mm bore plus our Accralite pistons. The standard crank is very strong but around these levels we’d encourage the switch to steel along with our Farndon H-section rods.

There's no point putting more fuel through a naturally aspirated engine without changing stuff to require more fuel otherwise it will just be running to rich and won't increase power , a high lift cam will give you more power

Haha think we posted at the same time artscoit :P

I think we are on the same page though

Thats got to be one of the most spectacular responses ive seen to a request for more power artscot. Ive learned a lot more about what is possible on a Focus engine in one hit than I have in years. Thanks

thanks ladd much appreciated. i take it i just get in contact with burton power and they will sort me out with parts and info and other things.?

sorry forgot to say i have got an induction kit on the above car also

thanks ladd much appreciated. i take it i just get in contact with burton power and they will sort me out with parts and info and other things.?

Yeah a tuning company will know what's needed but as artscot says , you'll need to increase lift and ignition timings via camshafts and remaps and airflow mods to require more fuel. So you'll probably end up needing a custom remap

burton power are ford engine tuning specialists check there site youll find out what is and isnt possible and what you need

thanks very much for the info

+1

Artscot i didnt realise who had so much tuning knowledge inside waiting for the right momment,

you must feel like a new person now mate you finally got it all out of your system :D

ive done more than my fair share over the years and made many mistakes believing that things were easy never mind lol
