hi this is my first post on the forum.

im trying to find out the best/easiest way to turbo my 1.8 focus zetec 2002.

i found lots of different information on the web some of which was a bit confusing.

things im looking to clear up are:

1. can i keep my standard inlet manifold ?

2. whats the best option for exhaust manifold ?

3. type of turbo for the 1.8 ?

4. is megasquirt an option for a zetec,there is information about it working with eec-iv and edis. but i believe newer zetec use eec-v .
will it work ?

its a budget build with a decom plate,and looking for around 200 bhp.

any help would be great

 

try useing the serch engine there is loads of information mate.

not many people turbo the zetec e engine its manily the early zetec found in the mondeo ect i think

megasquirt is stand loan magement so it does not need to work with your standard ecu it will replace it edis is a modual that comes one early fords and is more of an ignition driver rather than an ecu

i would say your best bet is a focous rs conversion

 

focus rs conversion would be great

but its a budget project im thinking of,limited funds etc

i recon going the aftermarket way works out a fair bit cheaper,

 

1. Yes, but you'll want bigger injectors.
2. Anything that fits and works. Focus RS is nice and simple.
3. For 200bhp, a T25, T3 or equivalent will suffice.
4. Yes it'll work fine. You can keep the EEC-V in there to drive other bits on the car and run MS just for the engine.

And note, you'll want some uprated valve springs.

 

i see by looking on the forum that you know about tuning,
i would like to keep my own ecu for immo etc.

im sort of thinking erst exhaust manifold and turbo as these are readily available at a decent price,

any tips for the inlet manifold ? will the stock zetec work with bigger injectors although i did read somewhere they are side feed and difficult to get .
rover turbo inlets seem to work iirc

 

The focus inlet manifold uses standard EV1/EV6 style end-fed injectors. Plenty to choose from out there.

ERST exhaust manifold wont bolt straight on without an adapter plate, or if you're really pikey you can drill/tap additional holes in the head. This does hang the turbo quite far out infront though and may foul the radiator.

 

yes i read somewhere all the bottom holes line up,but tops need drilled and one on the top n/s iirc enters an oil way on the zetec head.so i doubt i would be drilling that one.

will be keeping all options open with this,theres a few things on fleabay at present,

 

So you want 200bhp cheaply, bike tb's decent mangement cams, cheaper still.
If you got a cheap duratec 2L, over 300 on tb's, no lag etc no turbo.
tabetha

 

You're not getting 200bhp on a standard zetec head at atmospheric, tabetha.

 

the turbo route seems to be a better project,
bike tb and cams would be good im not doubting that.

ive never done a turbo conversion before and,but most of tech guys think its the way to go for the ultimate tune.

as i say im using relativly cheap sourced parts for this,and keeping the zetec block standard as i only want 200/210 bhp.
if things go pop then at least its been a learning experience,
i would then have the confidence to build a better one the next time.


@ pa_sjo i was wrong about the side fed injectors,older zetecs used these

do cossie ones fit ?
or do you know any other ones i should be thinking of

 

Cossie injectors would fit, yes.. You should be able to do 200bhp on a zetec on a set of standard cossie injectors. Your management will need to work with low impedence injectors though.

 

megasquirt should be able to do this am i right ?

any other cars that would be suitable for an injector swap ?

 

Yeah MS can do it. Not sure about the current offerings but on the older ones you had to have a 'flyback board' or something for low-impedence stuff. Might be integrated now, you'd have to check.

Any car that uses EV1/6 style injectors that has over 200bhp should be a suitable donor car... injectors really isn't a big deal so just get something that'll work and carry on with the rest of the project

 

im struggling to find an adapter plate for my 1.8 zetec turbo converson bin told to search for a site called cmc or cnc but nothin comes up bin told there are around Ł107

 

You'd be far better off using a FRS exhaust (log) manifold. It is after all designed to both fit the zetec head and the Focus engine bay. There are still plenty around, and cheap, and not cracked like many ERST ones.

As said, unless you want to just run a track car, you have to retain the EEC-V to run all the ancillary electrics from alternator through to the instrument cluster. Take out the MIL bulb and use a V3 Megasquirt to run the engine.

The standard inlet manifold (and TB) is fine if its the single piece moulding (>2003), its what the FRS used. Don't know about later (multi part) ones. FRS injectors come up for sale every now and then (42lb) and obviously work. You'll need (ideally) an uprated (or FRS spec) intank fuel pump, have to drop the fuel tank for that as the Focus doesn't have an access hatch.

What are you going to do about a 220mm/IB5/hydraulic clutch?
