couldn't you use LS rods with the GX pistons, they have the 21mm wrist pin, and the same length as a d series. just a thought.

I could get some LS rods, but like any d series crank, I'd have to have them machined down and I didn't feel like that investment. As it was I had to spend $53 on one new d17 rod. Then you have to go to the dealer for the bearings because there isn't any aftermarket coverage on such new rod bearings.

If I was going to go with any other rods, I'd use the A20 rods I have because they're as beefy as the b-series and they have a 19mm wrist pin, same legnth as the d16's and the rod journal is the same as d-series. You simply need to shave 1mm of the width of the rod at both ends.

turbo sol

just a thought, you can find them for 40 all day with pistons, maybe less if you get just the rods, and the mchining is easy and should cost more than $20 for all 4 rods,All that is needed with the GX wrist pins is to thin down the think end to fit between the counter weights of the crank, this would only be something to think about if you are goign to use them with the GX pistons (21mm wrist)

if you stick with a 19 mm wrist then it sounds like you have done your homework on the a20 rods. (i didn't know that about them)

A20 rods? Where do those come from exactly?

dsCRXsi

So how would a stroked d16 do with a supercharger?

And nice work! and do you have an idea on what you spent? over all?

dsCRXsi

What is your estimated budget for this project?

And what would a supercharger do to this motor?
Good Bad Explosive?

I think that overall I've spent about $600 with all the bells ans whistles. This includes my hookup here at work on new parts and whatnot but overall I'm very happy.

I wouldn't suggest any sort of forced induction with a 11.2/1CR however if you changed up your piston's or had them milled down more then I did then I'd think about it.

A20 rods, or the a20 motor for that matter, 1986-1989 accords. Carb or Fi, it doesn't matter.

Pretty sure that they are from late 80's preludes and accords. My mom's '89 Accord LXI has the A20A2 engine.

A20 rods have 20mm pin... wont work with d16 pistons...

You really need to dyno this!

psileepR

bump for a good new idea.

i calculated about a 1.45 r/s ratio on a d16 motor using a d17 crank (94.4mm) and stock length d16 rods (137mm).

that is even worse than an h23 r/s ratio (~1.48)

Im wondering was would a safe redline for the stroked d16

xci_ed6

he is running d17 rods

Man... Im wanting to do a D-series build up too, damn good post bro...

i'm just throwing some ideas around but if you post the block i'm pretty sure you can have a pretty safe high redline...

no?

considering the fact that the internal parts are all light as it is compared to larger motors...

a book i have laying around about hondas ( either civic duty or "how to modify honda engines" ) have examples at the back that talk about a stroked D16 all the way to 2.0-2.2 liters!! and a nice redline at 7 grand or something!! go figure ( i need to get the book back from a buddy, i'll post up more reliable info later on)

so uhh yeah!!

7thGear

also something to chew on

sounds like an awesome project. its rare to see originality around honda forums because of the sheer number of people, and the fact that most good ideas have already been done! I am also curious to see some dyno numbers. Id be willing to bet that this motor puts down quite a bit of torque compared to a stocker. good job man

M_Bureau

This thread is killing me... Someone hook this guy up with some Dyno time!

Any news yet? New developments, kill stories, anything?

By the way, I have a theory on the "Thinness" of the D17 rods... Did someone at Honda do this so that they didn't have to change the block casting to retain rod swing clearance? (Just a guess, as I haven't actually ever seen a D17 rod in the flesh)

<FONT COLOR="blue">**edit** Oops, just realised (from reading Alt.Honda posts) that rods are thinner along the axis of crank rotation because of the smaller journals on the D17 crank, not thinner at the base like I had imagined. Sorry! [/edit]</FONT>

Let us all know how this project is progressing!

any update?

crx_88_si

ok im all confused here.. what EXACTLY did u do to get this all to work!?

redzcstandardhatch

bump it up.

stmotorsports

WOW - I'm impressed...
I have been wondering if this was possible for awhile now and have just recently started amassing parts as kind of a side project, but now i definitely know what to look for...
Just out of curiousity, could you clarify why you ended up using the z6 pistons instead of the GX's? Was it the valve reliefs or the wrist pins? Maybe I just misunderstood but it sounded to me like you said the GX pistons share the LS's 21mm wrist pin size(?)...

MAD PROPS to you for being a pioneer in figuring out something that a lot of people have been wondering about ever since the introduction of the new d17.
THUMBSUP x100

ps- is there going to be any updates to this on sohchonda since alternativehonda is apparently no longer active?

Westrock2000

What are the GX and PDN pistons from??


Also, just imagine this thing sleeved and bored. Talking 1.8L+....like 120-130Ft-Lbs!!!

Ya what he said

So using an A20 rod (shaved a little) with D17 (DX??) piston is the most compatible?

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">
OH YEAH, shaving? The d16 or b series rods need the crank journal narrowed a few MM......I didn't have any rods shaved, I simply used the d17 rods because they're the same legnth as the d16 rods, just obviously fit the narrower journals on the crank.
</TD></TR></TABLE>

So I guess this is best bet, just get the whole rotating assembly. Crank, rods, and pistons.
