Cam Shafts

[Guest oshiney2]

hi guys fitting 2 litre cam shafts to my 1.8 zetec what if any increase in bhp can i expect

[Guest marsbar]

I am not an expert or any where near one but I have been told that the 1800 in the escort that was the sport model that had the 2litre cams fitted developed 130bhp with fuel injection, put bike carbs on and you should get 155 to 160bhp, but you may need a megajolt to sort out the advance on the ignition.

 

Enough to give Brown Trousers!

 

 

Good luck

John u dinnae ken what to be up to do you. Your zetec runs sweet and already chases 150 horses doesn't it ? Spend yer cash getting that dash Sorted out ;-)

He has got them already for peanuts. I was up yesterday.

Hi

 

It is not possible to say the power you will get, or not, with out considering other factors that effect engine performance.

 

the old saying "you don't get something for nothing" does apply.

 

some info I have found. http://ford-force.forumotion.com/t49-zetec-camshaft-identification

 

note the changing of more than cams to get a little more power, and the effect else where.

 

some info as to what you are doing, http://www.howstuffworks.com/camshaft.htm

 

you may also have to look at compression ratio, induction, exhaust etc to get any meaningful results.

 

Only way of testing is rolling road.

 

A lot of advice is available on the Internet, but always be suspicious. Ford have a very large budget for their research and development. they are probably going to get it right. that does not mean you can't get a few bhp here or there, but there will be a cost somewhere, and it will be a FEW bhp.

interesting stuff thanks

Hi I see you have included Steves message. I am not sure I agree with Steve when he says there is only a little extra BHP and what's more most of it is almost for free, so to speak in tuning costs.

 

 

Ford did indeed spend a lot of cash on the Zetec, it was spent with Yamaha. The design aim at the time was to produce an engine with low fuel consumption / Co emissions per mile for the Road Fund Tax increase due. The end result was an engine restricted by the induction and exhaust systems.

 

I have been working on the 2L Zetec E but the material I have referenced is linked to from my web pages My link under the Zetec page, where there are links to many resources from there. The 1.8 figures obtainable are recored therein with the modifications needed to obtain that BHP.

I have the 1800 zetec with 2000 cam shafts, and I'm well impressed. The power is instant, and when I first gave it some, I must admit, it did make me go "Geezzzus" as I came very close very fast up behind another car. I even had to overtake it in a bit of a hurry.

It isn't the fastest car on the road, but it is very impressive for the cost of doing it.

Mine has Megajolt, ZX6R carbs (2000 model(J?)), Pipercross sausage filter, 1.75" primaries, 2" secondaries and 2.25" final pipe with a 600cc free flow bike end can.

hi sorry i havent been back intouch mine is an 1800 zetec with r1 carbs and megajolt and piper cross fliter aswell when you changed over was it prity simple or was it just a change over and make sure the timing was spot on ? or did you have to have the car retuned? oh can you tell me the firing order ? many thanks obe

[Guest The Modfather]

The only time I used a timing light was to check that the megajolt was advancing/retarding as I revved the engine. The cams were already in the engine when I got it, and even then I didn't know if the engine worked, or if the timing was correct. I just wired it up, fitted the necessaries and fired it up. The engine ran on the second try.

I'm wanting to get it on a rolling road but happy at the moment as it is.

I believe the firing order is 1-3-2-4, but google it just in case.

Rhubarb! 1342 is a better way to go. As it's wasted spark it doesn't matter much. Fires 14, 23, 14, 23, 14, etc. Mind you it does need you to put the leads for 14 on the front two posts and 23 on the back two assuming the coil(s) are mounted where Ford put them on the back of the head.

[Guest oshiney2]

haven't a clue what you are taking about ???????

[Longboarder]

Sorry. Firing order of zetec is 1, 3, 4, 2.

As it is wasted spark the coils (there are two of them in one unit) fire cylinders 1 and 4 together then half an engine revolution later fire 2 and 3 together, then half an engine revolution later fire 1 and 4 again, then 2 and 3 and so on.

On each firing of 1 and 4 together only one of those cylinders is nearly at the top of its compression stroke and goes 'bang'. The other is nearly at the top of its exhaust stroke so the spark for that cylinder occurs but achieves nothing. Hence wasted spark system. Hence you need to get the HT leads to 1 and 4 on the correct coil and 2 and 3 HT leads on the other coil. The Ford coils look like one coil with four posts for HT leads but are two coils with common supply and separate earths for each coil. The computer fires the coils alternately every half revolution of the crank. It makes no difference to the computer which lead of 1 or 4 is on which post of the coil for 1 and 4. So you can swap 4 for 1 and vice versa. The engine runs just the same.
