Complete D series info
 
Some good info in here for those of you who want to build a sohc for an allmotor application. Contrary to belief they can make very good power when you put them on the same level as a b/h/f/k series in terms of compression and displacement.







enjoy you sohc heads lol

fully built N/A sohc:


some "race" d's:



converting from dpfi to mpfi on ef's

I'm building a D15B7 engine with a stage 1 cam, H beams, 8.5:1 pistons, ARP head studs/nuts, ported & polished head, 50-1 Garrett, and Neptune and can't wait! Oh yay...running a HF trans for fun...boost for days. Bump for a cool ass sticky post!

honduh_head 06-21-2008 12:06 AM

with the right bolt ons to go with that compression it should be fun... im thinking 140-150 whp and decent torque. will def put the hurting on stock b series.

honduh_head 06-21-2008 12:06 AM

haha sounds like fun in deed! thanks too btw :)

rooster 06-25-2008 11:53 AM

great thread--built sohc's are sexy

honduh_head 06-26-2008 09:26 PM

yes they can be...im trying to research a semi built d16z6 and cant find one....freakin driving me nuts lol

honduh_head 06-28-2008 10:16 PM

D series mini me Q and A
 

ef2d15 02-08-2009 05:37 PM

a d16a6 block and a d16z6 head is a very good mini me build with some boolt ons and it will be quik

eg2 panda 03-29-2009 10:54 PM

its alot of work....but hey the end result is what matters i love my SOHC

92BlackEgMTX 03-30-2009 07:51 PM

turbooooooo

92BlackEgMTX 03-30-2009 07:52 PM

i was going to build a d series for a longggg time just never got the guts to do it.. still have the pistons and rods to do it just never actually went for it..

honduh_head 03-31-2009 01:48 PM

its possible, but it would take a lot of work... a lot of guys get their builds into the 175 hp range with all oem internals and a good cam.

just look at the threads i posted and do some research... i actually would love to build a nasty ass SOHC. oh wait i have a single cam... in my V8 hahahahaha

89hatch 06-03-2009 11:40 AM

looking to do this build real soon. any suggestions to help increase hp??

die in a dick fire noob 06-03-2009 12:04 PM

cam, high comp pistons, etc...

Mat*speC1 06-03-2009 12:48 PM

mine is almost done...cant wait...i need a couple more parts...

89hatch 06-03-2009 01:10 PM

so im thinking of rebuilding my a6 block with a machined crank (since it has a spun bearing) and using sum 88-89 integra pistons with the z6 head. that should give me a decent amount of power right? is there anything specific i will need to do such a build?

The President 06-03-2009 01:25 PM

uhhh... what?

89hatch 06-03-2009 01:28 PM

???

hondafan2 06-03-2009 03:55 PM

so you are using zc pistons instead of the d16a6?

89hatch 06-03-2009 04:42 PM

yeah i would like to. they would give me more compression but i am concerned with the stroke. they are a lifted piston so i dont know if i could use them or if i had to change to a thicker head gasket or what. thats why i was asking if there is anything more specific i would have to do with that kinda build. thanks for the input...

The President 06-03-2009 05:12 PM

DOHC ZC pistons at that. :lmao:

I'm sure there is a better alternative

ILIKETODRIVE 06-03-2009 05:36 PM

Not really. There's isn't a large aftermarket support for D-Series.

No, you do not have to use a thicker head gasket. Heck, go ahead and use a Z6/Y8 gasket instead of the D16A6 gasket (0.037 vs 0.048).

There are actually 2 different "styles" of pistons. The difference between the two is seperated by what year DOHC ZC/D16A1 they came from (or are for). 1 style has a fairly large dome and a slightly lower compression height than the D16A6 pistons (88-89), the other style has a very small dome and a slightly higher compression height than the D16A6 pistons (86-87). The more common style is the 88-89 because with the compression height of the piston being lower, you do not run into any kind of risk of piston-to-deck issues. It's actually lower (numerically higher) than stock D16A6 pistons. The 86-87 style are basically zero piston-to-deck (according to zealautowerks), which is why they aren't that common of a piston swap.



That is THE ONLY GOOD online calculator for Honda's.

The President 06-03-2009 05:42 PM

so... D16a1 (dohc zc) will drop right into an A6 engine? hmm.. learn something new everyday.

is it just me, or do they not show the 88-89 ZC A1 pistons?

ILIKETODRIVE 06-03-2009 05:47 PM

They're both 75mm bore. Both styles of ZC pistons and D16A6 pistons have very similar compression heights.

FYI - all D13's through D17's are 75mm bore. :thumbup:

FYI x2 - yes, there is such a thing as a D13. It's 75mm bore/73.5mm stroke! It's oversquare like a B16! The D14 is 75mm bore/79mm stroke. IMO, best D-Series block.

honduh_head 06-03-2009 07:27 PM

Jesus simon u need to get out more lol

Jk luvu

Thnx for the input

die in a dick fire noob 06-03-2009 07:56 PM

i'm glad you came in here to clear these things up i was just going to have to type a large post...

and imagine throwing that down in your sig like hte people who say 85x89... oh yeah, 75x79 motherfucker!

<3 babycakes.

89hatch 06-03-2009 09:27 PM

good shit!! thanks guys. will let you know how build comes along when i start next month.

honduh_head 06-03-2009 09:31 PM

Hahahahaha

ILIKETODRIVE 06-04-2009 11:28 AM

lolz

I might have to source a D14 longblock and build one for a daily. Then join H-T just to make a sig that says that!

honduh_head 06-05-2009 12:32 AM

ya well mine is 3.9 x 3.622

beat that!
