ok i've gone and stuffed a pair of Cosworth cams into my 2008 focus and hit a bit of a snag.
I know they were made for the 2.3 but the lure of free cams was too tempting. heres the fact

They fit perfect
timing is stock
the '08 has 6 timing pickups for the Cam angle sensor
the Cosworth has 1
The cams work great performance wise
car wont start first couple of tries engine light comes stating cam angle sensor fault.
Cam sensor has been replaced with new one

I would like to keep the cams seeing as they do work. I would just like to fix the starting and engine code problem.

my question is can the timing be changed from 6 to 1 with the ecu

or

does anyone know any great engine builders who could take the timing ring off the '08 cam shaft and adapt it to the Cosworth

any info would be greatly appreciated

All I know about cams in an 08+ is that they repositioned the cam sensor in our generation and that means previous cams won't work with ours. If you've found a way to get past that, post up a how to cause I know many that would kill for it.


Id also PM Tom about your no start and code.

You can't use those cams. Been there, done that. The only way to do it is to change to a pre- '08 ecu or go with a stand alone ecu. Either way is a big job. The pre-'08 ecu will not plug into the '08+ wiring harness.

The location of the cam sensor is not the problem, it's the 5 pick-ups. The '08 is looking for these 5 signals.

For all of you ECU programming experts, PLEASE prove me wrong. Tell me that you found a way to make this work, I would love to be wrong.

All motor is MORE expensive! Trust me... (See mods in profile.)
If you turbo, you get power and otherwise it behaves like it should.
All motor, is a CRAZY idea for those who like narrow power bands and crabby idle... Like me.

Nope they don't work in our gen the most u can do is buy some stock cams and do some custom grind to them ask psurivie he was selling a custom set of cams I was gonna buy them but maybe later when I do the 2.3 head swap

^yeah, I still have them. Crower did a custom grind for me. I never installed them because I went FI. You're best bet is to go this route using stock cams. Crower got me a grind somewhere between there stage 1 and 2 Focus cams if you want to compare them. There is not enough cam lobe on the stockers to get a stage 2 grind out of them. Crower and I went back and forth for a few weeks to get them right. I can email the spec sheet if you would like.
HOWEVER, while typing this I just got an idea. Since you have your stock cams, I'm wondering if you could swap the "spur" from your stock cam to the Cossie. Doing that the ECU will get the proper signal it's looking for. I would call Crower and ask them if you could send them the Cossie cams and the stock cams so they can compare them. Maybe all they need to do swap the spur over. They are really nice and will gladly help you out. It's just that your car will be down and out for awhile.

Thank you all for your replies.
Thanks PSU I completely forgot about regrinding.
Granted if I could get my hands on blanks that would allow any grind. But the cosworths I have are the stage one which just gives a longer duration and keeps the stock lift, so a regrind would be easiest to pull off.

I looked more into swaping the timing spur and noticed that the section of cam where it sits is a larger diameter then where the timing prong is on the cosworth. I have pictures but you'll have to wait two weeks until I get home from work. Sorry.

So my next corse is a regrind of the stock to match the duration of the cosworths and then shim up stuff. Yay old school mods [wrenchin]

I should document this

I wonder how feasible it would be to make a ferrous trigger wheel that could bolted/welded onto the end of a 2003-2007 camshaft that had the trigger wheel grounded down.

That is the easiest thing I can think of short of paying for a custom grind.

You should document this! And dyno to see what power you make afterwards, what supporting mods do you have?

Update! Sorry for the long time since I first posted this topic. But here is the nitty gritty

As far as the cosworth cams they were still in the car.
I say were beacause as of last March I had to sell the car because I lost my job. Sad is me.

But for those who have been waiting for an 08 cam they do make them now for the 08+ models. Yay us. I know massive speed systems sells them and I need to check but I'm sure they are a crower cam

Which reminds me of the saying, all good things come to he or she who waits.

For my own bragging rights even though the car is gone here's what I had done to the car.
Cosworth cams
FS werks 92 octane tune
FS Werks 2.5 inch race exhaust
FS Werks cool flow intake
AEM dry filter. (Awesome for those who don't like the oil sucked into the maf sensor)
HR lowering springs
Tokico blue dampeners
17 inch Ford racing wheels wraped in falkens
Beat my neighbors svt with cold air , exhaust and tune so I was happy

I'm going to rebuild this 91 rx7 convertible I picked up so I'm not gonna be doing a focus for a while. But I plan on visiting this site still

How the Cosworth camshaft today, was thinking of doing this to my 2010 SES Sedan Automatic. Does it affect its everyday drivability and transmission?

No idea actually I was forced to get rid of the car due to losing my job. But if you want a camshaft for you 2010 I would go with the crower cam sold by massivespeedsystems.com the cosworth worked if you don't mind a cel all the time for a cam angle sensor and not being able to start your car without having to crank and recrank and crank again and pray your next cranking is close to tdc. I'm sure power wasn't all that it could have been with the older style camshafts but it was fun. As far as driveabilty yes its a very tame camshaft but stop and go traffic ate my fuel like it was free. A lot was due to my original tune. My car was tuned for Alaska air. 0-100 foot elevations and an outside air temp that never saw more then low 90's.... ever.... so I was sucking in some pretty dense air already. So add more air and a the cam angle sensor issue I would go much leaner then I should have been and the car compensates with more gas. I would be lucky to get 19mpg in town. Good thing Alaska towns are small. I got 32 highway with the cams doing 80mph. Before the cams I was getting 35 city and 42 highway so its a big difference at $4.40/gal it got a little better when I moved to Texas to a high elevation. Less air in and less fuel was being dumped away. I got a small bump in city 22mpg. And highway dropped below 30 MPG @80mph but gas is cheaper.

So if you want cams just know you'll lose MPG but gain grinabiltiy.
Drivabilty is dependant on the person I guess. Can you put up with the drop in MPG and loud noise. Then yes its drivable with the mild cams.

But don't use the cosworths they weren't meant for the new motor. Like posted before massive sells cams made by crower that have the shutter wheel required by the 2008-11. And they are cheaper.

The issue is that I do deliveries for my Job from time to time but not far ones and not to the point where it's affecting my car. But I'm putting new lighter rims on mine and FS Werks race exhaust with my k&n intake. After that I wanted an oil cooler to remain cool in these hot days in Florida. I am thinking about a turbo with an intercooler at very low psi to not ruin the stock internals, it I have an automatic which kills on my options with mods. ?

The fswerks focus for the shoot out was ran with stock cams with the 2.3 Ford racing heads and Turbo plus other things and put down 400 HP. If you're gonna Turbo they have a complete kit to Turbo the 2.0 duratec on stock internals. I haven't seen any reviews on the durability of the kit but 11psi with the 10:1 compression isnt superhuge but I'd at least replace the gasket and get some arp head studs just to be safe.

If youre stop and go traffic I don't recommend cams or turbos either way your gas bill will increase. The only real mod I can see being drivable in town and letting it off the chain everynow and then would be a nitrous system. I have a 20 shot in my 91 rx7 other then that and exhaust I haven't bumped up the power. I still have a very tame traffic vehicle and can still play around with other people in their rides. But I would still replace the head gasket and get arp studs. And have it professionally installed so you don't blow up your motor by going lean. That was a mistake I didn't like learning.
