I have a quick question concerning cams for a friend. He has a pretty hefty motor being built. Its a 2L with 12:1ish compression and the head will have a P&P etc.....well he is kind of in a toss up between which cams to use. He has narrowed it down to Skunk Stage 3's or Jun Stage 3's. The motor will be in a daily driver, but it will be more for race use. What we are looking is for honest first hand reviews with each cam. We've done a search but it has a lot to do with mosty hear/say. Lately I've been hearing a lot of positive feedback about the Skunk3's...and we're familiar with the power that the juns can give. We are also aware that the profiles for both of these cams are not similiar to one another. But any feedback from experience with either one of these cams would be great. Thanks in advance.

Hey man-

.. Anyways, we're putting togather a B16 for high revs and going with Jun IIIs.. We'll have it up and running in about 2 weeks. Let me know what you decide Jesse !! Jeff

The guy that does all of my dyno tuning said that they dyno'd a fairly high tuned car with "all of the leading cam manufactures" and said that the crain cams are the best he has dyno'd......anyone else?

 

lol crane cams..

anyways. the stage 3 hasnt been street friendly i heard. someone commented to me that the stage2 is better for street/strip and is closer to the Jun3 in tuning and power.
stage3 SK2 may have too high of a lifT?

 

My first hand experience with these cams is, I have built motors with and assisted in the tuning with both several times. This is what I have seen, and remember failure is much more likely with any perfomance part of there extreme nature. So IMO.

Yours friends motor sounds like it is ready for either cam, from what you have described so far.

Jun 3 cams fail (break) much more than any similar cam.

Skunk 2 stage 2 are almost identical to jun 3.

Skunk 2 stage 3 cams have the potential to make the most power, although I haven't seen it yet.

Skunk 2 stage 3 cams like at least 13-1 cr

For your friends motor I recomend Skunk 2 stage 2

 

thanks guys....anyone else??

how about some toda b's

 

So Trever, what about a less aggressive cam like a Stage 1 with a C/R like that? Possible for mid-range or tq?

 

1's are also good. I made 15 over R cams in the mid range with them. They won't carry the tq as well as the 2's. They are more forgiving on valvetrain and thats a plus. It's all a trade off, I liked the 1's when I had them.

Toda Spec B 12 mm,duration - 255 @ 1mm 12 mm, duration - 245 @ 1mm
Toda Spec C 12.5 mm,duration - 255 @ 1mm 12.5 mm, duration - 255 @ 1mm

Jun Type 2 12.0 mm, duration - 266.6 @ 1mm 10.9 mm, duration - 265.3 @ 1mm
Jun Type 3 12.0 mm, duration - 265.3 @ 1mm 11.5 mm, duration - 265.3 @ 1mm

Spoon Sports 11.53 mm, duration - 256 @ 1mm 11.13 mm, duration 245@ 1mm

Skunk 2 stage1 11.58 mm, duration 252 @ 1mm 10.9 mm, duration 249 @ 1mm
Skunk2 stage 2 12.3 mm, duration 266 @ 1mm 11.8 mm, duration 262 @ 1mm
Skunk2 stage 3 12.8 mm, duration 273 @ 1mm 11.5 mm, duration 273 @ 1mm

These are jus VTEC lifts but by *looking* at the specs the JUN's look more friendly to the lower 12:1 compression setup. I would think of trying the Toda A's and Skunk's Stage 1's both of which I think are ITR valvetrain friendly and *shouldnt* need a stronger timing belt. I put the ITR/CTR cam spec's in just for reference.

Integra Type R 11.5 mm, duration - 240 @ 1mm 10.5 mm, duration - 235 @ 1mm
Civic Type R 11.5mm, duration - 243 @ 1mm 10.5 mm, duration - 235 @ 1mm
