Has anyone had any experience with aftermarket cams on the S? Was there a big power gain w/ tuning? Do some cams still keep V-tech?

Any info is much appreciated.

Thanks.

 

Cams are not an effective upgrade when used in conjunction with common bolt-on modifications. Unless your intake manifold or a similar major component is modified, the stock cams are great for a relatively stock set-up.

 

headers,exhaust,gears, vafc are the most common mods. and its v-tec

 

cams are a good upgrade if you are using the cams with the proper additional work, such as a ported and polished head, a port matched intake manifold, a port matched big bore throttle body, and a really good header and exhaust system...all this used in conjunction with a proper tune, using aem ems and youre looking at some hefty gains.

as for cam types, toda is the best out there, but there spec a cam is pretty mild...the also make a spec b and c, but both require using their high compression piston kit along with it..

hope this answered your question

 

I concur... they are all but worthless power wise without head work, raised compression (read: pistons... there is no headgasket method that can be used with aftermarket cams), and stand alone engine management... ITBs would be a plus at that point... regardless you are talking about 8-10k...

 

Toda Spec C cams do show good gains, but like said above, there is a lot of work on top of the cams that is required.

For the Toda's you need to also get:
Piston kit - $1200
Valve springs - $400
Cam gears - $700
probably EMS ~ $1500

then the cams - $1100

So about $5000, but if you also have a good header (J's), good exhaust (J's 70, Amuse R1000, T1r 70), intake, bigger throttle body, and a little headwork done at the same time you'll see good gains. My guess is at least 20hp possible due to: compression raised, headwork at the same time, and the Spec C cams.

Alone its not worth it, but if you already have intake/exhaust/header/throtle body/testpipe then they can show decent gains.

If you wait a few years I'll tell you how it works out. Although, I probably wont do cams alone. Since I may opt for 2.2L at that point and do everything at once, 2.2L crank, stronger con rods, Toda pistons, ported/polished head, valve springs/retainers, and cams. With all of that at once, hopefully I can show people the S2k can be an N/A beast. Couple years though

 

It's "header"

 

It's possible to get 20 hp without cams and head work.

 

hope you are kidding because it is vtec.

 

Yes...I already have. Look at my mod list, I'm making about 220-225whp. I don't have that much
