Adjustable Cam Gears (Fidanza)

Okay so I have the oppertunity to purchase some adjustable cam gears. They are the Fidanza ones and they are used coming from a ZX3 with the 2.0 Zetec.

Now I know I cannot tune the intake cam because of the VCT. But my question is can I still replace the cam gear on the intake so it looks good in my engine bay? So basically just pull the stock one off and put the aftermarket one on?

I know the gains are minimal, if anything it will look really good. But how much can I gain by tuning the exhuast cam gear?

Thanks!

You can get the VCT delete and use the intake cam. If you have them dyno tuned I'm sure you could get some nice gains out of them. But as far as just replacing the OE one I don't think you can.

No you cannot replace the intake cam gear. The entire intake cam gear is a functional part of the VCT system and cannot be removed from the cam without deleting the VCT with an adaptor.

^^^Correct.
And, Tom (Focus Power) played around with an exhaust cam gear for quite some time on a dyno.
Gain was there, but as is usual with these cars, it was negligible...
^^^Somewhere between 3-5hp.
Worth it? Maybe...maybe not...

VCT=Variable Cam Timing.
The SVTF has VCT on the intake cam.
It's there for performance (to keep the torque up down low) and emissions.
Hence...no EGR system on the SVTF engines.

But...as with most complicated systems of this type, it can fail.
When that happens, you can get the VCT Delete kit, and not worry about it ever failing again.

so you get this VCT delete kit, and then get the same function by adding the cam gears?

No, not the same function.
The VCT adjusts the cam timing all the time when it's running.

With the adjustable gear (dyno should be used) you set it and forget it.
It only gets adjusted once.
It's a compromise.
You can set an adjustable cam gear for top end, or mid range, or bottom end, but not all three.
Which, is what the VCT does.
It optimizes the cam timing at all rpm ranges.

well that sounds pretty nice, Id like to have some pretty cam gears to look at, but I think Id rather have the full range auto timing thingy working.

same thing with just the exhaust gear? needs dyno tuning, eliminates something else thats useful?
