right got a really good question for you zetec and cozzy engine boffins

1) so what is actualy the difference between them two engines apart from the turbo

2) why is is so hard to get a decent power or 1/4 mile time in a 2.0l zetec lol

3) and is it worth me getting cozzy management on my 2.0l zetec

thank you

 

are my questions too hard for you lot

if its any help iv got

newman fast road cams,
polished ports on the inlet and exhaust (head)
polished and balanced crank,
lightened and balanced flywheel
cone air filter k&n
de-cat down pipe
1.6 si gearbox

all in a fiesta

 

1) have a read, the differences are quite obvious... different bore, stroke, compression ratio, ones normally aspirated ones forced induction, different port shapes, different port sizes, different valve sizes, different manifolds etc etc etc

2) 1/4 mile time isnt just down to the engine, its down to the car its bolted into, in your case its a fiesta which isnt renowned as being the best handling car, so your probably struggling with a poor chassis (assuming you have a mk3 fiesta) and poor suspension setup.

3) you cant have cossie management on your zetec as its not a turbo'd.

and which one of your questions do you class as really good ?

 

You cvan run cossie management on normally aspirated but pointless, it is not the best system anyway, I am changing over to a EMERALD 3d ECU.
You would be much better off with a aftermarket ecu, the reason the zetec may not seem so good is because it was designed around a whole different aim ie emmisions and as low as possible, whereas the cossie lump is only a rusty old pinto with a different head, basically but head work and turbo is what does the biz.
A NA engine of the same power will always be slower than a Turbo one due to torque differences, but can still be made very fast, but at a much greater cost, as cossie has most if not all the major components already needed.

ar reet cool cheers for that, just had a look at the emerald ecu thats one of then ecu's that you can program your self isnt it?

the first question becuase i didnt know it lol

 

EMERALD ecu can be set up with your own map, but will be supplied FOC with base map if you ask.
KARL the man who designed these ECU's, and works for emerald with DAVE WALKER knows his stuff.
These ecus also have a host of useful features including switch selectable different maps, map interpolation, and a load more.
They plug straight into all K SERIES engines(looms), rovers, lotus etc.
They can also use a multitude of different sensor inputs, and fire coilpacks direct, use either vaux or ford trigger patterns, so all sensors dirt cheap as well.

SWEET! cheers for the help ill have a gander and speek to them

oh and im in the prosess of sorting how the car was running one of the egr prongs had snapped where the join is at the tubes so it was blowing and one was all clogged up doh! so im getting rid of it all he he he he

 

EGR is not too bad, PULSE AIR is a pain in the rear, but easier if you take them both off.
Just make sure you keep the EGR PRESSURE DIFFERENTIAL SENSOR, as this may need to remain plugged in, it may default to LOS otherwise.

already done sir its sorted out a flat spot at 4000, it idles a bit better and it seens to rev harder in forth wich is where i was getting the f0ults more noticeable coz its 1:1

 

You should post some piccies up ?
I fixed a mondy today that had a running problem for two years, no codes, no dealer with a clue, one s/h TPS later perfect, was still well within range, so did not show any error, just not in range with the rest!!
Easy Ł20, don't know about the new technology, can be a pain sometimes.

what of my car or the engine?

i dont like electrics i prefer good old engines and old carbs
what was his problems with the car?

iv just tested out my car against my mates 1.8 mondy and where i use to pass his with a nackered 2.0l 118bhp lol now he passes me so im going to get a 1.8 gti inlet to see if its better other wise its back to morspeed with the base ball bat

 

The problem was just the car shuddered when idling, and used to occasionally cut out when started, but only when hot.
Emissions were perfect, drove perfect, ace on fuel despite being and auto does around 35/40mpg, averages 460/470 to a tank before fill up.
Piccies of the car + engine, just like piccies.
My dad is the same as you he prefers the carbs, and points etc, oh and starting handles, man in front with red flag!!
He has a V8(4litre) xr4i though!!, did not minde me putting the engine box electrics etc in one of those, even made me cut and shut a ROVER SD1 exhaust(ss) to fit his 4i, we are on SU carbs but going injection with emerald ecu soon.

ar reet cool, my cars better now iv got the air flow meter dissconnected for some reason even though the air flow meter works lol tis crazy,
oh and the piks are up of the car
