So i have been working on this d17y8 build for probably around a year now just slowly buying parts and doing a lot of research. ive read through danz d17 thread about a billion times and that thread really motivated me to want to build this so thank you danz lol.

so plans.

block
d16y8 .5mm over sized (also decked .009" for flatness)
d17 crank
new oem d17 rods
arp rod bolts
new oem .5mm OS d17a1 pistons
new oem rings
new oem rod and main bearings

head
d16y8 head (mill .016")
crower stage 2 cam
crower valve springs and retainers
fully ported
ferrea 5000 flat faced valves.


looking to get around 11:1 cr. on 91 octane.
dont really have any power goals just what i get is what i get. would be happy with 140whp and 115ft/lbs.
tuned on chrome pro by a local business who specializes in hondas.

okay so lets get to some pics.

took 3 people to get it in there. took me a cherry picker and a jack to get it out.






now moving from my nice bright comfy shop here

to my nice dark garage that i dont have a picture of.

got the d17 crank, oil pan, oil pump, pully, and stuff


have to rig up the oil pan to work with y8 stile dip stick


have to rig up the oil pum to work with the y8 style dip stick


heres it all together

okay. so my new rings came in and got them all on then the pistons went in.

couldnt think of anything cool to put on my pistons so i went with the obvious.




got the arp rod bolts tightened up.



then i notched and installed the girdle.


when installing the girdle i did something incredibly stupid.
well i switched the middle two bolts with just two random bolts.

and since the middle ones are longer they didnt tighten down well.
so my dumb ass forces it to tighten down.


and it was just this one but i jacked up the block.


its only on the outside so it shouldnt leak oil but from were the main seal bolts up.

i think ill just get some devcon and just fill it in best i can. and try to keep the main seal from leaking.

next have to get new main seal water pump. and a few other things and the block will be done.
then its time to start on the head.

^^^you think so? i dont think there is enough room for the hondabond to seal well.

know of anything cheaper then devcon that might work lol?
You could weld it, but I think it will be fine how it is now as long as the spot doesnt open up any more.

Did you buy those pistons from honda? You do know there are factory high comp pistons for the d17?

you serious?
i did not know that lol. oh well these are in and everything should work out fine.

i dont think the hole will open any more but i may just get some devcon. i would rather be a little bit more safe then sorry lol.
There is a natural gas D17 motor, pistons new from honda are $200 they look similar to p29 pistons.

Im debating using those pistons for my next d17 build and shoot for 13+ comp.

shaving the head an flat faced valves.

after decking the block .009
then i will take .016 off the head to a total of .025 off.

zeal claims thats 10.62 with a .037 head gasket then add .3-.5 to the cr from the flat faced valves and walla 11:1ish cr

so i got some crap from autozone that is supposed to patch holes.

i put some in it and i think it might work.



then i grind-ed it down carefully till it was decently flush.




then i put on some rtv and put on my main seal. hopefully it will hold.

soon will have the oil pan and water pump and really most of the block put together.

Well I shaved .030 off my block and ran a .027 HG and my compression calculated out to about 10.8:1 thats why I asked.. But I forgot you have .5mm more bore which will make the CR a bit higher! Nice, cant wait. It should pull hard with a nice round bore!
