does anyone know if the bottom end of the D17 and D16 is interchangable?.... I mean can I use it on the D16Y8?

:?:

 

[soccaian]

infinate and i have tossed the idea around a few times, but we can't seem to come a conclusion as to whether or not it would work... i guess someone should donate a spare d17 block and let us find out! :lol:

Ive pondered that thought a time or two. Be nice if the crank fit a D15. Im still looking for a D13 if anyone finds one. I just want the bottom end. I like its small bottom :shock:

 

[R0Y]

well..... this came to mind coz my friend have one sitting in his shop and it's taken from an Si = Ex but the thing is that we don't want to play with the direct injection stuff so we're thinking if the bottom end will bolt up to the D16Y8 head.... plus then I'll still be able to use my jrsc :twisted:

I'm a tech at a dealer, and recently pulled a d17 out of an 02 ex. To start the head gaskets from a d16 and d17 are different. Not much matched up.
Pistons pins on the d17 are placed higher on the piston than the d16's. d16's have a 90mm stroke verses a 94mm stroke on the d17. Nominal bore on the cranks are the same at 48mm. I am doing more research when I go back to work on monday. I'll get some pics of the rods and crank up as well.

Great! ED9ory.... keep us posted

 

[ED9ory]

no prob I'll try.

Awesome info. Can you tell us exactly what's supposed to be "oval" about the pistons too? That's another mystery that nobody really knows the answer to.

By the way- which dealership do you work at? I grew up in Houston, and I'm up in Austin right now. I'm curious.

:mrgreen:

'00 and before GX pistons use 21 mm wrist pins, '01 and later use 19 mm wrist pins.

Per my thinking, just have LS rods shaved and use '98-'00 GX slugs.

Calesta, I work at John Eagle Honda. the "oval piston" is not visible to the naked eye. I cant see it and the micrometer I have is too small to get readings of the piston. If you want I can post a pic up of the piston.

Sorry to Hijack but can you find out the rod length on the D17's ?
Thanks

Thanks ED9... I just wonder where exactly they're supposed to be oval. If you're not getting any out of round readings on a mic, it's got to be a direct fit in a standard D series 75mm bore, right?

I'm curious about the rod sizes as well- can you measure them? How about the compression height in relation to the other D series pistons? I heard they moved the wrist pin up quite a bit in the D17 pistons... is that true too?

 

[R0Y]

so does that mean that I can completely forget about this D17andD16 combination...... since it's like impossible :?

 

[Perfectionist519]

According to the piston comparo page, D17 pistons have a 27mm compression height.. D16's seem to be somewhere around 30mm.

If the D17 rod length is 140mm (compared to D16 137mm), I would assume that you could use D17 rods and pistons in a D16, and better the rod/stroke ratio from 1.52 to 1.55.

Crank journels are a differant size

 

[Perfectionist519]

What's differenet? The width of the rod, or the diameter of the bearing surfaces?

If the rods are a bit wide, they could be shaved like LS rods..?

Anyone know the length of the rods?

 

[Guest]

The crank journal is a different diameter if I remember right. I>E. it wont bolt up to a D-16 crank.
