Hi guys I've heard a little about these, are these a good mod to use with the standard ek9 cams? They seem relatively cheap? Any know much about them? Do they need to be tuned with an aftermarket ecu?

Thanks

a good idea would be to get a nice aggressive exhaust cam(toda spec of your choice....)leave stock intake cam and add a set of adjustable cam gears along with an aftermarket ecu
 
The "cam gears" itself doesn't give any gains in hp, the adjusting of the cams give you more power, I've heard from friends that tuning the oem cams can give you some gains, but don't expect that much. Also the only way you can do this is having a dyno session to tune your cams with the cam gears.

Hope this helps.
 
cam gears change the power band, what ever power you gain you will lose somewhere else...
 
that's not necessarily true. I suppose IF you wanted to, you could make the motor a true dual nature beast by having lots of midrange pull and no top end.

Most of the losses are mitigated by ecu tuning and the trade-offs are generally worth it. In some cases, many would definitely be willing to sacrifice 2-5whp at the top end in exchange for 7-10whp in the midrange over a wider rpm range.
 
If I was to buy cam gears, can I run them with a standard ecu?
 
yes but as said gains would be pretty much pointlessly minimul, you would need them set up properly using dti gauge etc, not just a case of bolting them on and trial and error!
 
i think if you have stock cams and ECU, its more trouble than its worth getting adjustable cam gears...as if not done right they can slip...

get it when you have cams and a ECU to map with.

Actually, it is a case of trial and error if you're willing to "tune" them yourself. That's how we did it many years ago and came pretty close with the final settings on a B16A with ITR cams and camgears.

This was also done with the stock ECU. There are gains to be had just by shifting the powerband around.

Slipping is not a problem. If you can use a spanner, you can cinch down the adjustment bolts just fine.

Would they be worth it for the money? Does the t/belt have to be done if I change them?

what i mean is you cant just bung them on and turn them a bit here bit there with out a clue,you need to know how to tune them, unless you want to risk bent valves.

well thats what trial and error is lol... some times you make an error, sometimes that error means good bye engine ;) ten years ago almost nobody had a dyno, the cheapest wideband A/F metering device was well over thousand dollars in any currency and just like now people wanted to go fast!!! Like my tuner for example can street tune so well that he only needs about 15minutes of dyno time to get most cars perfect :D its cause when he started that was the only option and thats how he learned...
 
there is a bit of a difference between educated trial and error and just all out guessing with out a clue though, thats what i mean;) you guys are crazy lol, i'd never guess my cam timing would be to frightened:lol:

Given my personal experience with them. I would say yes.

Just don't do any drastic changes like intake/exhaust +/- their maximum range.

Generally, cam timing is +/- 3 degrees is on either intake/exhaust is a safe acceptable range. Any further than that I have no experience with and you're on your own... :drive:

Timing belt does not have to be changed unless you're due for one.
