I know we have a wide variety of opinions about these 2 camshafts, but I wanted to know which one will make more power out in the long run, I am in the market for either or.

My set-up as follows:

Skunk2 camgears
JDM 4-1 header
Apexi N1 exhaust
Aem POwer pulley
V-AFC
AEM CAI

**I will be also getting a hondata system soon**


any advice

 

Those cams NEED compression kid. Stock 10.6 ITR static compression won't take full advantage of the cams.

Pistons and hondata should be next on your shopping list.

 

gracias any other suggestions?

 

Peak power will be about the same, but Toda B's will have much better midrange and torque. Toda B

 

actually peak will go to the skunk stage 2 cams while midrange and torque will go to the b's.

 

what compression would you use to match those cams. also, what compression could/should you run with stage 3 cams? I have hondata and injectors, but I still wonder how high of compression I can run with 93 octane.
p.s. I am thinking of selling my turbo kit and associated parts for an all motor set up, I already have an ITR tranny and want to run jun stage 3 cams with what compression, I dunno.

 

with toda b/c or jun 3 cams, you can run 12.5-13:1 compression with 93 octane only and good tuning since you have the hondata. so thats a pretty high compression street setup. remember bigger cams reduce compression, and need more compression to run appropriately. i would not build anything less than 12:1 with those cams

 

that is what I was looking for, I want to go with 12.5:1 pistons. how do the cams reduce the compression though?

 

I agree. I drove my friends JDM ITR hatch to get dyno'd one day, funnest trip ever. Toda B's and bolt ons with a super light flywheel was a lot of fun. They ended up dynoing 206hp, 138tq. When you get on it, the transition from low to high cam is so smooth that you don't feel a kick or a change in sound, it just keeps pulling. Incredible midrange on that motor, even with the stock compression.

 

cams reduce compression in that a bigger lobe lowers compression values. its called ABDE specs of the cam. do some research on H-T or the net and you can read for yourself. its been covered many times

 

What about a JDM ITR Block that yields 11:1 compression, would that utilize the Skunk2 II's?

 

I think it's the pistons that yeild the 11:1 on the JDM motor, but I still think that's too low, personally.

 

CTR pistons are the way to go

 

There are two types of Compression Ratios. Static and Dynamic.

Static compression is just a mathematic ratio of cylinder volume to combustion chamber volume. For example, an engine with 500 cc per cylinder and 50 cc per combustion chamber has a static compression ratio of 10:1. This is what people are referring to when they talk about compression ratios.

Dynamic compression is how much your motor actually compresses the air inside the cylinders. Dynamic compression is based on how much air is actually in the cylinder during the compression stroke. To simplify things it will suffice to say that running a lot of overlap on the cams causes some loss of dynamic compression.

these are some great info guys keep them coming

 

mk is explaining it very well...he summed up the articles i told you to search for in about 2 paragraphs. basically if you want my true opinion, if you want to run toda b/c, skunk 2 stg 2/3 or jun 3 cams, your STATIC COMPRESSION should be no less than 12:1 to take full advantage of these cams. a few very respectable tuners recommend at least 11.6:1 compression for these types of cams

todas will give u much bigger power gains over skunk2

 

That is a very vague answer it is all about tuning

Check the cam specs out on each cam here:

one needs to look at the lift on all 3 lobes. not just the vtec lobe. vtec lobe lift only tells you peak power and not how much low and midrange power
