Hi all,

I wonder if anyone did run these cams ? I am planning to do some upgrades to MY04 engine so any information will be appreciated.



Thanks

Theres alot of other supporting mods you need to make these cams really shine. Need higher compression, pistons with deep valve reliefs, the basic i/h/e, a tuneable ECU (EMS), valve springs, cam gears, and all that other mumbo jumbo. In the end, you will make more power by bolting on a supercharger by only spending half of the cost of the n/a stuff.

you will most likely need an engine management unit, preferebly the aem EMS.

I actually have heard good things and bad things about AEM EMS. If I do it I want to do it right. I am looking MOTEC M4 for fuel management system.

For these cams, I wonder how much power will I be expecting ? How hard are they to tune ? How's the wear to the valvetrain ? I used to Toda Spec-C on my B-series engine and they are such a bitch to tune. Can you guys provide a bit more info here ?

I understand SC'ing the engine will cost less or maybe more power but Honda built this engine NA out from the box and I would like to stick with NA.

Unfortunately i don't think you're going to get much feedback for your questions. I don't think anyone on this board has tried the cams because of all the costs required to get the cams to run well. My suggestion to you is to start with the small and easy stuff first. A standalone ecu with a good i/h/e combo can get you some pretty decent gains throughout your entire bandwidth.

I'm sure an experienced tuner won't have any problems tuning them for you. One thing that you don't have to worry about on this engine compared to the b-series is the timing belt snapping/shredding on you. I got a shredded timing belt on my old b-series when i had toda b's. All 16 of my valves got bent .

Thanks for the input. I guess we are on the same boat I got I/H/E and an ECU at the moment but I cant forget that kind of power that my B-series used to make. I believe the F22C engine has way more potential than this.

Thanks again

^I couldn't agree anymore. The f20 and f22 head flows so much more than the b-series could even dream of.

The spec C's require new cam gears and pistons and tuning. Expect to spend lots of money for not much improvement. If you want power go FI.
