i have 91 crx with a b18c5 swap.been looking for my next upgrade when i came across this guy sellin these cams....know with a stock c5 would i have to upgrade spring and retainers or will she be fine..secound what would be the better cam the skunk stage 2 i can get for 400 and the crower stage 2's i can get for 350..

 

I would do a search since there are mountains of information on cams for that engine on this site.

You will absolutely need to change the valve springs.

 

I have got skunk2 pro 2's...havent reved high enough yet to feel vtec though..

 

i been loking on here and cant find anything on thu..

 

the skunk 2 pro 2 will be alot more agressive than the crower 2. there for you will need more compression for the skunk pro 2

 

I believe he said he was looking at the Stage 2's not pro 2's. Stock compression will work but 11:1 or better is what Skunk recomends for those cams.

 

koo im starting to think i should leave the c5 stock.

 

skunk2 for 50 bucks more i would get them

but i love my crower 2

great mid range cam to top end cam

 

Skunk2 Stage 2 and Crower Stage 2 are COMPLETELY different cams. The Sk2S2's are BIGGER than Crower Stage 3's! I have the Crower Stage 3's. You can run the stage 2's without upgrading the valvetrain- i know many people who have, and one person who has 25k miles on his with stock valvetrain.

 

JR, I absolutely love my s2s2's but I wouldn't recommend them at all on stock springs.

Plenty of people have done a lot of things that "have worked for them for 100k miles" but that doesn't mean you will be a lucky one.

I'm pretty sure he was refering to the Crower stage 2's not the S2S2's that would absolutely require valve spring upgrades. From the sounds of it, the Crower stage 2's would be similar to the S1S1's or less, which don't require valvetrain upgrade.

 

You are correct, I misread that.


I am a valvetrain worrier.

I personally have never destroyed anything but I know plenty who have by under building and I would hate it to happen to a friend.

Hell, if the crowers are smaller than s2s1, then they wouldn't be much different than ITR's anyway would they? I am not too familiar with OEM cam specs.

You are correct, the Crower 2's are similar in lift and duration to the ITR cams. The non-vtec lobes are a bit bigger though, which creates better bottom and mid, but a worse idle and higher VTEC engagement.

My Stage 3's dont have VTEC engagement until 5900 rpm (4400 being stock on a B18C1).

ummmmmmm.........no.

 

That was extremely helpful Rollo, in the spirit of tech, would you mind enlightening us with numbers or are you just sticking with a vague "ummmmmmm.......no" because it helps you sleep at night to play I have a secret?

CTR cams

Intake-duration @.050" = 240 lift w/1.55 = 447
Exhaust @ .050" = 232 lift w/1.55 = 416

Crower Stage 2

Intake duration @ .050" = 255 lift w/1.55 = 466
Exhaust @ .050" = 248 lift w/1.55 = 466

here you go.

 

A bit more lift, but the duration is almost the same. (what point would there be for Crower to make cams identical to ITR cams?)

buddy, you are missing the point. you'd be hard perssed to find other cam manufacturers that equate rocker ratios into the equation like Crower. so, when you see other manufacturers advertising 265-270 degrees of duration, that is measured at a higher spec. include the r.ratio and the specs decrease.
