Here are my results (before & after dyno). I also had a light P&P job done while the head was off, but it wasn't very aggressive, so I don't figure it made that big of an impact (maybe 1-2hp).

To summarize, the cams didn't do squat below 4K but made 6-8hp above 4500RPM. Keep in mind that this was with the stock intake, header, catalytic converter, and exhaust.

Here are the results after I installed a VAFC and AEM CAI:

I highly recommend that you get a before and after dyno. The gains are so slight with these cams, that it's nearly impossible to tell if you're making any power at all. Actually, shortly after my install, I found that I was actually losing power. If I hadn't performed a dyno, I may have never even known it, because my butt dyno isn't sensitive enough to tell.

 

What are the benefits of Todas cams, i thought this car was already tuned out aggressively. Will the toda cams produce significant performance results at cost?

I just wanted to bring this post back to the top. Has anyone that encountered problems with their initial install of the cams been able to find a resolution? Does anyone have before/after dynos for "botched installations"? Speeeding and myself seem to be the only ones that have posted dynos with these cams, even though several people have claimed that they lost power with them.
Speeeding's dynos indicated a loss on the low cam, but gains on the high cam, and that seems to indicate a problem with valve clearances. (I saw similar results, and resolved it with a valve adjustment).
beroznikmal indicated a loss across the board, but never posted a dyno, and never posted whether or not the problem could be resolved.
mugens2003 posted that he was getting the cams installed, but never posted dyno results.
Teds2k posted that he had seen a loss on the first install, but then a nice gain on a second install, but never posted specifics on what was fixed to resolve the problem.
Wicky posted that he gained 3hp across the board, but that doesn't sound right for these cams. They generally are even w/ stock up to about 4000 RPM, and then curve upwards up to VTEC crossover. Above VTEC, they generally make a consistent gain to redline.
VeilsideAP1 posted that he was getting the cams installed, but never posted back w/ results.

I'd like to see more information regarding the problems and solutions that people have with these cams. I'm currently running a set of these cams that are losing power, and I can't figure out why. Considering the number of people that claim to own (or have owned) these cams, I would think that someone would have seen the same problem that I am seeing, and has been able to resolve it.

Anyone?

 

Have you adjusted your valve clearances since the cams were installed? What clearances did you go with?

 

Has anyone tuned these cams with a standalone ecu? The VAFC is inadequate when trying to extract power from cams. I'm not surprise that alot of people are losing power by slapping these cams in and not really tuning them. Have any of you thought about getting cam gears to adjust the cam timing?

 

Those cams were probably the worst investment I have done in many years......
first run - lost power.
second run - no loss no gains....

I used the dyno sheets to wipe my ass cause I was so angry.......
I did not look into stand alones cause toda promised a 10 HP in crease by tuning it with a vafc period...
Bottom line is TODA USA SUCKS ASS..... I will never use their product again ever.... give it to me for free, Ill take it and use it for paper weight.....

BTW, I thinks u missed Wantone.....

 

I've re-installed them about 3 times. The first time I went with whatever Toda recommends (.009" intake & .010" exhaust, I think.). The second time, I went with 1 thousandth tighter on the intake, and it didn't make a perceivable difference. The last time, I went back to Toda's recommended values. The dyno chart does not look like the mis-adjusted valves issue that I had originally.

Cam gears are just a crutch. The cams themselves should make proper power without needing cam gears, assuming they are installed correctly. Also, an EMS will definitely unleash more power, but it shouldn't be required to make power. The VAFC helps just by leaning out the mixture where the stock ECU still runs a bit rich.

 

so how about someone trying to put 04 S2k cams into a 03? I know 04s redline at 8k but they spike there too... meaning there might be some more available...

Ive seen a comparison between torque/ho curves of 03 & 04 and the curves dont match at all! there are spike in the 04 where there are dips on the 03... Id love to see someone try this to see what gains/losses there are...

 

I don't want to be an ass or anything, but after 18 pages of talk about these cams, I'd really like to keep it on topic of the Toda cams & issues related to them. If you want to talk about swapping the 04 cams into an 03 (which I personally don't think would be a good idea), please start another thread to discuss that (besides, you'll probably get more relevant feedback that way).

Thanks.
