Specs for a D17a

[Soulless]

I was wondering where i can find the specs on this motor..Like the stroke. Mainly the crank and rod specs.

[custom_junky]

bump...i would like to see this as well

[dj02]

from the horses mouth ofcorse :D link to specs (http://www.hondacars.com/models/specifications.asp?ModelName=Civic+Sedan)

[pitchblacktyper]

its SLOW and thats all you need to know

[Rexinre]

We need to sticky some things for the D-17. It should get some more attention then it is.

aside from the b21 non vtec motor in the old preludes, this is the next to ugliest stepchild honda ever produced.http://www.d-series.org/forums/images/icons/icon13.gif

[kyosoeg6]

im personally looking for pics of the pistons. anyidea where to find that info from

I can agree with that one!

[pitchblacktyper]

i think its 7thgencivic.com can hook you up on the pics. just have ta search around on there.

[stmotorsports]

I can agree with that one!

nah the d17s are good for some stuff, you just gotta know what stuff ;-)

[Rexinre]

Just don't like the way it looks!

[pitchblacktyper]

good for door props and rat mazes..

[Import Al]

The D17 hasn't been developed fully or received enough interest, but is a G engine. Its lite, torquey and has a tested design. It makes plenty of power with current kits like TSI extreme, Dezod, SF stage 2, DH-Racing, etc. 300+whp manual A2 in an HX and you'd be flying ;-)

[Soulless]

I have plans to use the crank and rods...
Thats not what i was looking for...I want the specs like lenght of the rods..differnce in stroke of the cranks and such..

[stmotorsports]

'01+ D17* stroke is 94.4mm, rod length is *said* to be 140mm, piston compression height is *said* to be around 27mm...
I have a D17A2 (EX vtec model) head that I measured chambers, came out to 32.8 cc's

I've been meaning to dig my stuff out & get measurements, have had too many other projects goin on the last few weeks tho...

Hopefully I will get a chance to in the next few days, planning on measuring cc's of pistons also.

If you're trying to put all the stuff in an older D16 block, it does work- do a search on h-t and sohchondas (or see my sig ;-) )

i did do a search on hondatech. ive found that the whole rotating assemblys fit in the d16block. however the compresion still sucks. under 10.0. what my question is, what pistons can i use or combanation of parts to get a comp ratio of about10.5-11.5

[Soulless]

Well, I guess I will go ahead and tell you my plans...

D16z6 block and head
z6 pistons shaved 3 mms (so they dont stick out the block)
D17 crank, rods and oil pickup

from the person that had this motor , slightly different, used y8 instead of z6 block and head, it gave her 11.3:1 CR.

[ametzzz]

is the d17 crank, rods, and oil pickup more efficient, lighter, or stronger?

[Rexinre]

I heard that the rods were thinner then the d16s. Anyone else?

yep- thats been my entire hold up with my project, finding pistons. I know there has been some people talking about using normal 30mm compression height pistons (D16, non-vtec D15, etc) and just having them machined down to match the deck height, but I haven't spoken to anyone thats successfully pulled it off. I'm thinking of trying to find some d15 vtec or vitara pistons but i haven't been able to find any piston specs on the jdm d15Bs

I like the 7th gen coupe w/some nice 17" wheels.

I've heard the D17 rods are lighter aluminum but can handle around 14 psi w/ proper tuning. As for pistons, you'd better off finding swappable ones than $$$ customs in a z6 block. Good projects!

al-um-i-num... ... .... ...rods??!!
:slap:

D'oh, meant steel. How light are nice billet steel con rods?

[freeturkeys]

just get urself a nice set of crower rods for the d17 then ya dont gotta worry about it

as far as i knew, the d17 rods were *supposedly* 140mm but apparently not...

anybody see why i don't think the crower stage3 and the stock d17 pistons wouldn't play nice? :cockbloc:

[Solblu]

Can you CC those pistons and give us the Volume?

[stmotorsports]

yeah i still gotta find a more accurate measuring tool, i could give a close estimate but thats about it till then

plus i'm kinda out of commission right now- scratched cornea YAY!! :sadface:

[sohcD17]

Ive got a d17 as well...its a 01 civic lx...wondering where i might b able to get a vtec head that fits my car..thanks

you should've gotten ahold of me a couple months ago- I had one & let it go for around $200
might be able to get another one

A1 Pistons.

[fastasfuk]

i have d17 block for sale its vtec its out of a 2000 it has 22k on it it was swaped out for a k series 600obo

[custom_junky]

are you sure that the car is 2000? the d17 didn't come out until 2001.

[d16a6crx]

ok, so im hopefully getting a d17a1 shortblock for free (hydrolocked, all rods are fawked) but, correct me if im wrong, i plan on using the d17 crank in a d16a6, with the a6 rods and pistons. the a6 pistons have a ~3mm higher compression height (30mm). how much more compression will this difference give me?

thanks

[fastasfuk]

my bad i mean 2001

you will have to have the a6 rods machined at the crank end to fit within the d17 journals and the crown of the a6 pistons machined down the ~3mm to a lower compression height so the pistons don't smash into the head. Even if you could get those a6 pistons in there without hitting the head, you'd still have some retarded diesel compression ratio. If that d17 you're getting was hydrolocked, make sure you get that crank thoroughly checked out by a competent machine/engine shop- there is a pretty good chance the crank could be bent or twisted

$600 just for the block?? did i read that wrong?

haha alright. i knew about gettign the rods machined to fit the journals, i forgot to mention that.

[br1anpham]

Reading this makes me want to try to get a D17 crank in a D16. Consdering I will need custom pistons anyway if i wanted to go 77.4mm bore, I might as well get some custom pistons for the D17 crank. Does anyone have any experience with cumstom forge internals? mainly the prices.

[stmotorsports]

UPDATE:

D17A2 (PLR-A0) piston volume: 6.4cc

.

[slyw/fbpsi]

The d15b piston has a piston height of 27mm as well. Race engineering has d17 pistons made by wiseco http://www.raceeng.com/showItems.asp?cat=IMP&id=10132331012054433345477711232344784322343236654 55111201132201232012235670343223223234343443223034 44323442344454343266&subcat=PS&Supplier=RACE 5th through 8th line down.
