I've searched but couldn't find anything. My wife is going to start saving up for pistons and rods for her D15B VTEC but we can't find what rods and pistons to get cause' of the obvious. Any help would be greatly appreciated... TIA

any 1.6L rods will work, but there are no pistons available. you can use PMS pistons but they will raise compression considerably.

So if I use the 1.6 rods and PMS pistons it'll raise the compression...

BUT...

What if I use 1.5 rods and some kinna other pistons.. Will that work? Why is it so hard to find pistons and rods for this block? Is it that different from any of the US blocks?

 

you cant use 1.5l rods the crank journals are differant sizes. the reason its hard to find a combo is because the 1.6l rod, one off stroke, and 1.5l block. basically the D15b uses a 1.5l block, 1.6l 137mm rods, destroked 1.6l crank.

 

You must use 1.6 rods. I am currently building a D15B with LS (B18B) rods and PMS pistons. The LS rods are the same length as the D15B's rods. This combo nets around a 10.3:1 compression. If you use the LS rods, you must notch the bottom of each cylinder to clear the crank end of the rod. You could use any 1.6 D-series rods, but you may end up with different rod lengths, changing the rod length to stroke ratio. Hope this helps somewhat.

 

all sohc 1.6l hondas use 137mm rods, so theres no problem using them. for some reason i was assuming he was building for boost or is already boosted. simply because the stock rods will handle any N/A power you can make w/ the D15b. you are right though, that LS rods work, and the cylinders need notched.

Didn't think about that... I am building it for boost, so can a 1.5 US crank fit in the block?

 

well, if you put a 1.5l standard crank in then theres no rod options, LOL, its pretty much a run it til it blows situation. i mean, cosmetic headgasket, and unshrouding the valves could make the compression work out w/ the PMS pistons. tell you the truth, thats a good idea. just have a reputable machine shop do the headwork. i will play w/ the compression calculator once i get home, and see what i can come up w/.

Cool, thanks! Do you have a link to these PMS pistons...?

 

OEM honda civic gx 01-03 piston. mega cheap too

 

Would those be good for boost? Or should I just find an aftermarket company that makes those pistons but forged?

So I can get Forged Rods for a D16z6 and forged pistons for an 01-03 civic?

 

compression is gonna be high w/ them, and i doubt anybody makes an aftermarket piston for the gx since its a fleet vehicle, but you could try. any 1.6l rods, pistons arent so easy.

 

Damn! So has anyone built one of these engines before? There has got to be something out there...???

 

nope, they run em til they die, then get another.

 

LOL that's what I was affraid of...

 

for what its worth, im running the D15B with GX pistons, all motor. feels awesome no need for boost haha. i dont see why u cant boost the d15b on stock pistons with forged rods...should handle more than a daily driver will likely throw at it, unless your goina get stupid.

I emailed the guys at endyn and they say <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by people over at ENDYN &raquo;</TD></TR><TR><TD CLASS="quote">

Unfortunately, the only aftermarket rods available for the D16 are custom billet pieces at $650.00 per set. We have made pistons for the D15's in the past at $485.00 per set.

Hi I was told that you guys might be able to help me. I’m going to be rebuilding my wifes JDM D15B VTEC engine for boost but since it wasn’t available here in the US it’s hard if not impossible to find a piston/rod combination. Do you guys do anything w/ that engine? If so please let me know! Thanks



Shane.</TD></TR></TABLE>




So I emailed them back making sure that they knew I was talking about JDM D15 VTEC and not the USDM one... So we'll see what they say...

yeah let me know what they say becuase i couldnt find and aftermarket off the shelf internals for the jdm d15b they keep telling me"should have bought a b16 and why didnt you get the z6 instead"

i would like to have a almost 300whp d15b stamped motor instead of buying a z6 block to build up but it almost seems like that what im going to have to do

That's pretty much the same thing here. I wanna build it just because it's not the common thing to do... But i'll let you know what they say...

 

They do make aftermarket pistons for the 01-03 gx. They are make by wiseco, race engineering sales them. http://www.raceeng.com/showIte...=RACE
They start at the 5th place from the top.

So you now you can user d16 forged rods and d17 forged pistons for your d15b vtec buildup

 

The GX is a 1.7L?

but what will the compression be?

I know someone who had vitrara pistons in his d15b vtec. The vitraras are usually 8.8 c/r in d16s but was 9.4 in the d15b. So, you would be looking anywhere from 9.4 to 9.6 depending on your setup.

Man, I wish my email notifications works, so I wouldn't have to check my profile on here

 

Im very ineterested in this D15B work, dont stop please. I have a D15B and I have a turbo layin around but no piping, but Im looking to beef internals soon. This will be a DD, but I want to be able to beat on it pretty good out on the mountain roads. So far I've read that I need the Z6 forged rods, and GX pistons. Will any Z6 springs, valves, retainers, etc. work? Any cam options?

From what i've read, the D15B has a pretty decent cam.. Might be good to stick w/ it? Don't quote me though since I don't know specs...

Where are the Vitrara pistons from or found? I need some info on them.. I think they are suzuki pistons right?
