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.

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!

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.

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

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?

so you are using zc pistons instead of the d16a6?

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...

DOHC ZC pistons at that.

I'm sure there is a better alternative

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.

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?

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.

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.

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!
