zc pistons and crower cam qustions

[Noodles]

anybody here have a crower stage 3 vtec cam just wondering what they thought
and on the website it say that the head will need michining can somone fill me in about this

in order to run that cam i would need to up the c/r
i was thinking of putting zc pistons on d15b7 rods
WILL THIS WORK?

and if so what kinda power it makes
has anyone done this before with this combo

im really a b series person and a kseries if i could afford it
but i love what people have to say till i tell them its a single gingle:shock:

What block and head?

If its a d15 block with VTEC head, it might be ok with the Z6 head, but with the Y8 you might want to clay it. Clay it with the z6 head too to make sure.

im sorry i have a d15b7
and y8 head
but i dident buy the head yet so if the z6 head is better
and also what kinda c/r am i looking at 12.5-1?

dammmm nice work u cracked the sleeve
what set up is that?
it looks like maybe valve float
or u droped a valve
i only say that b/c i dont see any marks on the other pistion

btw i was searching threw the fourm and found a compression cal
with
y8 head stock d15b7 lowerend the c/r is 10.6-1

and with the zc pistons ont the d15b7 rods ana a y8 head the c/r is
10.9-1


now is the d15b7 pistion a flat top or dished?

Thumbs up for crower. They make a great cam, I love my 2, and I'm sure I'll love the 3 when I get it next summer.

Regarding ZC pistons, if you want a good deal on new oem ones, take a look: (if the mods don't mind a little helpful self promotion)

144whp is nice.....if you dont mind could u tell me your setup

[Eyal 951]

Thats with a stock head and such. I'm lookin for 165-170 whp and hopefully over 130 wtq this summer.

Follow this link to my setup:

[SOHCpower]

lol i only made 124whp with zc pistons in my y8. what engine was u usin?

[s_18]

144 whp is very good for your setup IMO... I only got 152... And that's by european standards, which translates to about 150whp.

Comparing our setups, I'm really hoping myDC 4-2-1 is holding me back.
I have a stage 3 cam, ported head, etc...

You have a few things in your favour though.
Slightly higher compression due to the Y8 head and a 0,5mm larger bore.
Slight increase in displacement over me, again due to the 0,5mm larger bore.

But the larger cam should even that out, don't you think?
I just think it's interesting to compare similar setups, and maybe try to find out what causes the differences.
I'm really hoping the Bisimoto header will do good on this setup.
Atleast I'll know how much of a restriction that 4-2-1 header might be.

Eyal, did you happen to measure your collector size? I measured mine, and ID was 1.9".
I think it's too small for a setup like this...

maybe u can answer my question
what kinda work does a z6 or y8 head need to run a stage 3 cam?

Some times you need to grind off a little material here and there...

Here's the thread describing it. The pictures that's stored on sohchonda aren't showing, as sohchonda is down for the moment.

That said, I didn't do any of this. Didn't really know it was a "problem" until after finishing the build.
Haven't had a problem so far though, thank the Honda god.

thank you for your help
today i finaly got threw to crower cam the honda tech was out sick the last 2 days
but i talked to them and they just said the same thing

this is good b/c i can do all the work myself
well thanks again for your help and i will keep your guy posted onmy set up

my set if it goes as plained
y8 head
d15b7 bottom
crower stage 3 cams and valve train
y8 2layer head gastet
a6 intake manifold ported by a friend that has pass away so im goin to use it in memory of him

hope to kill some b16 if not ther is allway spray

p.s there is a few people im comming out for with b16's
make room for the underdog:shocked:

[Eyal 951]

I have followed your setup fairly closly since its so simular to mine. I thin the 76mm bore results in huge gains on a vtec motor because since the intake valves are so close to the cylinder walls, and larger, the cylinder walls actually impede flow on the vtec motor, hence why vtec motors issues that they are no better then non vtec (even though we have better cam profiles, larger valves, more displacement sans the a6)
By giving the valve an extra mm, I think I have done great stuff for the motor, not to mention the simple benefits of displacement. Look at my tq numbers, and the curve is very flat, aside from a dip from the short ran intake, which is actually a spike with a CAI. I intentionally did certain things, such as the displacement, and flat top pistons, y8 head for its combustion chamber, to encourage high TQ numbers, and the car really feels great from 3K on, but especially after 6K.
I'm definelty jealous of your bisimoto header, I want one badly. This summer I will have some headwork done (probably by alaniz) move to stage 3 cam, aftermarket valves, and a well built, harmonicly tuned ITB setup. I'm hoping to hit 170 whp. I'm not sure if I can di it with the DC, but with a bisimoto or smsp, I think its a plausible goal.

Yeah, I guess a 78mm bore would do great on my engine, but the cost of a new block was just more than I could have taken.
Will be exciting with your new setup. I would like a set ITBs myself, but it's not going to happen probably.
Maybe some day.

Well, the one's im having made might become an affordable option for good quality properly built ITB's, but I'd like to get em on the dyno before exploring that route.
78 mm would be great, hell my 76mm was a huge improvement. Next time you have the block out, take it out to .040, its worth it.

[s_18]

Can't get the Roller Waves in 76mm, and they cost too much to ditch like that.
And the next time my block is out, I'll probably swap engines or something...
Maybe the K20 is more affordable by then... ;)

Fine, but you have to build a K20 all motor. 300whp.
