oh thanks now as far as pistons and rods

IIRC D15b7 pistons in a D16Z6 engine and a 2-layer HG will yield what, 12.5:1 compression? You could slap a Y8 head on for a little higher compression ratio. This will get you into the N/A range with oem parts.

i got d16a6 motor it in 89si hatch

SKarpenz
04-04-2009, 01:37 AM
Yeah I totally ignored that part. LOL

But it shouldn't make a shit, aren't all D16's the same on the lower end (for the most part) minus pistons?

04-04-2009, 01:40 AM
so whats realistics numbers on whp

SKarpenz
04-04-2009, 01:46 AM
High 100's maybe. With high compression and cam/valvetrain. Doubt you'd make over 185whp. Maybe I just don't have much faith in the SOHC as an all motor app.

jerseyef9
04-04-2009, 01:48 AM
i would be happy wit 170 man to be honest i know they don't have that much room its okay just like the sohc for now later when my budget is up to par i will get in to the swap thanks for your help

SKarpenz
04-04-2009, 01:49 AM
Yeah bro. Just don't expect huge numbers from the SOHC. If your using OEM shits then it won't matter anyway since you wont be deep in $$$. Good luck with the build.

allmotorX
04-04-2009, 01:29 PM
Hmm 150-160whp on a sohc would get you into mid to high 13s n/a you can put zc pistons in and i would say keep your head and get bisi level 2 regrind cam pnp the head a lil thinner headgasket maybe 2layer like the above statement, i/e/h and youd be good for 13's

bigdare23
04-05-2009, 03:20 AM
You're luckly if you get 145hp out of a N/A d


Most n/a motors with 150hp+ have some $$$ invested. My suggestion would be to throw some boost on that motor or do a swap. Don't get me wrong, I went down that path of the n/a build d, but got rid of the parts before I finished because after researching people with similar builds and seeing thier results I decided it wasn't worth it.

Starrfire
04-05-2009, 09:54 AM
In laymans words, you ain't getting 150 whp. All of these engines you see that do have some serious secrets within them, and most of the people that say they are "stock" builds are lying like hell. You'll be lucky to get 130 whp out of that setup. D series motors that make more than 150 whp cost about as much as a cheap k swap.

04-05-2009, 04:32 PM
Dont build it. I put close to a grand into the head of my n/a y8.
Big mistake, huge waste of time and money.

I will be doing a sohc build n/a just to have some fun with it but I do have a gsr with 13 to1 compression and some nice head work with flat face vales the same will done with the sohc or higher people may say don't do it but what every I say just do it too see what it makes and what it do people told not to go high with the gsr but it is still running with no problem so do what you do and keep it moving and if you blow it up how much is a sohc vs a gsr ok then

jdm93civic
04-07-2009, 11:30 PM
I think he could get in the 150's. I would say y8 head. Here is my suggestion.
Bore it .20 over
11:5 - 12:5 Comp Pistons
H-Beam Rods
Valvetrain
Block Guarded
Tuned
And do research on what bolt ons make power and don't. I beleive you will be in the 150's or really close. For a DD that is all I would do.

God damn dude, punctuate much?

I agree though, do it to see what you can get from it. Run high octane and get it tuned and you may surprise a lot of folks.

i don't know man, all motor d motor that could spank folks would be extremely nice, but i think the amount of money and time invested into it, over the life of the motor, might not be worth it. but really, money not being a problem, anything is possible. i just want to send my 95 civic coupe into the 12's with a sohc.

u just need higher compresson and a bunch of head work thats the week point in the d's.......

-EX tranny
-Vtec head y8-z6
-Cam stg2-3
-Valvtrain
-Ported-match the intake man.
-High comp. 11:5-12:1
-Tune
- U should be around 140-150hp, and that will beat/stay with most B's

if you want a budget build 150whp d series...they dont exist, i have done it. here is what it took.

honda cbr 954rr itb setup with porsche trumpets (complete custom)
je 11:5:1 ceramic coated pistons 78mm
custom stainless header
one serious p&p (Z6 head)
ferrera oversize valves+springs+retainers all titanium
hondata s300
crower pro billet rods
arp rod bolts and head studs
cometic head gasket (alot thinner then stock)
acl race/main/journal bearings


was not worth it

my bolt on h2b makes the same power as a bolt on K. i don't see why more b swap people don't do it. The torque is way better than my other gsr hatch. i run the same times and mph's as a k too. I wouldn't do a k20, but rather a 2.4 hybrid would be the only k I would do.

Well...time to put my two cents in...I had a built d16z6 and achieved 146 whp, so I know 150 is attainable. Just not cheap. I'm building another d series n/a now. Gonna try to get 160whp who knows. Here was setup on the old d:

D16z6
PnP head
62 mm throttle body
Stock Intake manifold port matched to head and tb
Hondata intake gasket
crower stage 2 cam
Ferrea valves/retainers
D16a1 pistons on stock rods
Y8 head gasket
Aem cai
Dc header
Magnaflow 2.25" exhaust
Cat delete
270 cc rc's
FPR
Holley fuel rail
Walbro 255 lph fuel pump
UR adjustable cam gear
Apexi vafc

also make sure you do other upgrades like msd ignition, fuel rail maybe bigger injectors..?

Craziest high hp hardware for a d series while keeping in a budget is:

Z6 head (straight ports vs. Y8's offset)
01+ Civic GX pistons
LS rods
ITBs (if really going cheapo then the Y8 manifold flows the best of a d's)
Bisimoto cam & valvetrain
and the other common stuffs: h/e bla bla

Minus the itbs it should still break 150 tuned

There is a guy in Washington state that has a old d15b2 with weber carbs, bisi valvetrain and cam, bisi header, and exhaust. Dyno'd 152 to the wheels on the original 150K mile bottom end.

I will be building a b7 block with a milled z6 head, sk2 valves, springs and retainers, crower stg 2 cam, zc pistons, sk2 int mani, 68mm t/b, G-SR injectors, 2 layer head gasket, hondata and I,H,E. We'll see what I can do puttin it in a fully gutted 95 cx if all goes well LOL. When we're done we'll run aight!!!!!
I wanna run you when you get done if thats cool, and that 68mm tb will be overkill!!! But do as you please

Ok. What do you have? And I have been thinking about that 68mm t/b. I will prolly go with a 62 instead. Parts are slowly coming so it might be a while.

I have slightly modded z6. If i were you i wouldn't go higher than a 60mm tb that way you wont loose much bottem end

Thanks! Didn't know that. And we'll see about the t/b may just leave it stock to save some ca$h!!!! If anyone else has any pointers for me they are greatly appreciated, this is my 1st build EVER!!!!!!!
