ive been looking around lately, and i dont know much about all of this frankenstein mess
but from what i understand
the zc (b16a9) pistons
d16y8 head
and
d16a6 block
would be the best build for this?

please correct me if im wrong
im very curious about this build, and i really want to look into doing it

what would the compression ratio on this be? estimated

 

Look in the FAQ for the compression ratio calculator. You can input whatever combo you want.

 

dang, thats pretty cool, haha, thanks!

 

i couldnt find it.. can you send me a link?

 

here use this one http://lmgtfy.com/?q=honda+compression+ratio+calculator lol use the first one thats on top. you meant d16a9 pistons? I like how you added the word 'SUPER'

 

Only because I'm in a good mood...

I like this one because it takes into account milling of the head/block.

 

wow i didnt even notice i said b... my bad, haha, but obviously the d16a9
and ive heard people say ranges of this from 12:1-14:1
so if so, then yes, "super" haha
atleast in my book

 

If you do the same setup you want up on top you should have a 13.4:1 cr dayuum that is SUPER high cr

 

haha
d15 block, and crank, d16y8 head, p29 pistons, d16 connecting rods, and an a6 headgasket
make 15.66:1 cr

 

I'd like to see you try that setup you just posted.

 

no way, haha, i know it wouldnt work, but its just crazy to see numbers like that
even though i just pulled up 116.88:1

 

now that im done messin around with that calculator crap

ive never done a build like this, much less a build at all

what EXACTLY would i need to do this?
d16a6 block, rods and crank
d16y8 head, and 2 layer headgasket
p29/pm7 (zc) pistons

and run 89 octane

this should make 13.11:1 cr


am i missing anything? even little stuff?
will this work and have valve clearance?

 

well your missing quite a bit if you think thatll just power itself ha, but yea you got the main idea down and that set up would work. Dont know what kinda car you have but you might have to convert to multi point and such also. Just keep that in mind.
There are videos on youtube of guys with all motor single cams that are pretty quick.

 

Will 89 octane run a 13:1 motor?
I think you are missing a lot....good luck

 

x2 get used to picked up the 94 octane or higher pump lol

 

well i knew that.. haha. but i was just asking, like, anything id have to convert and such
idk, but i have a 91 ef hatch (dx)
but yea ill need to do the multi point swap, convert to obd1 or 2?

its automatic right now, but i picked it up with all the parts for the 5 speed to manual swap, an extra d15b2, d15 tranny, eg seats, eibach springs, and extra interior pieces.. even though im gutting it, haha
but all for $600
so im hoping doing to do this build, and swap to manual, with the extra $700 i have
is this realistic? ive found the parts pretty cheap so far..

 

thanks!

 

If you do all the assembly AND have a way of getting all the parts not to mention gaskets/seals/machine work at a cheap cost then yeah you can do it for $700. Now considering you've never done a build as stated above you probably won't be able to do it for $700. Why don't you try pricing it out and total it up.

 

oh btw, the kinda dumb part on my end, this is going into my dd, haha
my friends are telling me this setup will not work
anyone that has experience with high comp engines?

 

might work but the chances of blowing up an amaturely built wayyyy to high compression for a DD car is pretty high. I would avoid this like the plauge. If you want to raise the compression. Do a rering, bearings and mill the head some.

 

I read through this thread and will give my advise.

Personally, i don't think the build is work it. For the money time and effort, you would get an engine with a peaky power band, still with little torque, and running a high comp engine like that for a daily would not be reliable imo.

For the most part, all motor d series are not worth it because other series engine are so so cheap now days. If you really have your heart set on a d series though, your best to start off with a dohc!! They are superior in design, flowing more air through every bit of the power band right from idle, and make more torque!

Something to think about

 

Definitely a big deciding factor, for the money invested you could definitely obtain a whole new(er) engine.

As for the DOHC ZC being superior in design, I guess that may be a debatable point BUT I have been running a DOHC ZC in my car for the last 8 years and I LOVED that thing like no other!!

 

What i meant was that a dohc cylinder head is better in design. Stock for stock, a twin can engine flows 30% more air than a single cam. More hp and more tq

Same rules follow with other series engine

 

well the thing is, im not super noob at this, i mean, my buddy is a honda tech, and he works on them all the time, i help, and learn what i can
neither of us are pros, however, hes deffinately no noobi just wanted a more professional opinion..
im thinking i might build this engine, then put it in a shell in the future, and drag it
but i thought of another build
its pretty much a mini me, but with a thinner headgasket
the d15b2 block, which i already have
with a d16y8 head which i can get complete for under $100

ive checked, and the cr for this build would be 11.0:1
thats not that high, but its alrigtht with me

any thoughts on this in a daily driver?
im thinking id need about $200 more to have this in and running, doing all the work myself, with my buddies help of course


anyone think this would be quick? with minor mods like chipped p2p ecu, skunk2 adjustable cam, dc or hp racing headers, and cai, mpfi swap
d15b2 tranny (si tranny eventually,but,what tranny is that exactly? haha)
in a completely gutted ef hatch (dx)
just dash, center console, and 2 front seats will be left, with no air bags, no p/s, and maybe no a/c, just heat for defrosting and for when its cold

 

No one here can tell you if this setup will be quick, it's subjective. Fast for you may not be fast to someone else. Go look up the "All Motor * SOHC * Chime In !" thread and read some of the people's setup to get a rough idea of what kinda of power/times their particular setups can do.

I find it interesting that you say your buddy is a Honda Tech but isn't a pro.
