i want to know if there is going to be any clearence problems, and does anybody know about how much power this would have

any help would be much appriciated, thanks

 

what kinda car

 

you should add a cam or all that compression will be wasted. you couls go ahead and use the ZC rods if you got them, they are a little stronger than the reg d-series ones

 

i think i read somewhere that the sohc zc block with dohc zc pistons and a y8 head netted something like 12:1 compression.

 

it is going to be in a 90 crx si, i will also be using the zc rods. i plan on puting it together just to drive for now and will put in a new cam once i get the money and a y8 intake manifold and soon as i come up with the money. i just wanted to know if anybody knew if there was going to be a clearence issue with the valves and the pistons, especially with a new cam, i do all my own work and sometimes get forgetfull and checking things.

 

the y8 head is gunna have hella high compression ratio and u mught have a problem with detonation and the zc pistons are goping to raise it another point so ud have to have alot of fun tuning ur fuel and timing .. idont recomend it by getting z6 psitons ur lowering the compression ratio a half a point to a more safe level for dayly driving..thant would be a smarter move

 

probly give u 108 hp to the wheels and a lot of torque..no clearance problems and maybe 103ft/lb of torque...and the y8 head should fit perfectly on the a6 bc there no prob with dist mount like on the z6 head

 

i have seen a magazine just the other day where people were running 16:1 i think 12:1 will be ok because here in wa you can buy 95 octane out of the pump and then i will run some octane booster on top of that, i wanted to let people know i'm also using a zc tranny for the low gears and its a little stronger. thanks

 

so much misinformation on this thread its great...

a6 block
p29 pistons (zc, 88-89 integra)
y8 head

will all be fine...yes you will get a higher compression ratio around 12 ish...not a big deal...

"put in z6 pistons and lower compression"

wtf...why? that would be stupid...that would make less power than a z6/y8, so whats the point in doing a mini-me then...

definatly get an aftermarket cam and do some tuning and you will have fun...

 

Where in washington do you live? i wouldnt mind seeing this done.

He's right. Have fun wit that "Octane booster" It'll raise your octane by like .00012323 points.
:reiterates previous *giggle*:

 

i will actually be using toulene, not octane booster. toulene is available at any place that sells paint. it costs about 6 bucks for 5 gallons and you mix a couple cups per tank. toulene itseft is 114 octane, so mix some in a it makes octane levels jump quite a few points. this along with 95 octane from any gas station here and 12:1 compression will make good amounts of power, but as someone else said it would make lots more power with the came also to utilize the fuel. and as for misinformation like senpei says, lots of people have wrong info, if they didn't there would be no need for technical forums like you are now reading.

Thanks to whomever I got this information from...

 

Id like to dispell this myth. All D series rods are the same diameter. With that said, I would go with the Y8 rods. Just because they are out of a newer engine.

Dont believe me?

Ill pull my ZC rods out, compare them with my D15b2, and my D16A6 rods... None is really any stronger than the other.

 

i swear there was a thread on HMT a coule weeks ago that had pics of them side by side, i dont remember who posted it

crx_of_fury, toluene isnt nessesary for a mini-me, good tuning is though

 

I built a mini-me several years ago(1999-2000), before they were common.
I used an A6 block, y8 head and I opted for z6 pistons. With i/h/e it managed a best of 118 hp and 114 tq to the wheels.
Way better then stock but not worth the money and time it had consumed to get to that point.
There weren't CR calculators that allowed playing with components and the impact on CR. By my early calculations back then, and I'm no engineer so mistakes are likely, my setup was going to be 11.1xx:1.
The z6 pistons do drop CR by about .5 so it made sense. 10.6:1 seemed high enough for pump gas at the time.
Would I recommend it now? Not really...people have proven 11:1 is realistic on pump gas.

ya u might see this in a magazine with a full blown racecar but if u are planning on turbocharging this car U WILL DETONATE THE ENGINE and if u are wanting a SAFE daily driver car then have fun when ur engine explodes ...also ur gunna need to be running it on atleast 110 octane not 95....because with zc pistons ur gunna be well over 12:1

 

hey listen *** clown ur the one giving misinformation maybe u should learn a little bit before u come replying to my **** like ur a ******* god.. but itn all actuallity ur just an ignorant bastard who doesnt know what hes talking about

that last one goes to this *** clown

 

I would love to see proof of 16:1 CR on pump gas. 12:1 will be pushing it on pump gas. I would have to agree with Nick in saying get the z6 pistons and lowering it to 11.5:1. On 93 octane this should be fairly agreeable, just make sure you have a decent tune. Overall though, you will never make much horsepower on a N/A D-series motor. Unless you are Bisi(sp?).

 

That was a stupid first post. Welcome to the forum. You can definately make power with NA D-series motors, and u dont havta be Bisi. Pulled this out of another thread I was watchin. Member on here and D-series named AgentJam is makin some pretty decent power on the sohc.
