Default ls rods in d16

Would anyone be able to machine ls rods to fit in a d16y8 with vitaras? I know its possible and has been done before but I dont know anyone local that I trust doing it.

not to rain on d16sandrail parade, maybe he can cut you a hell of a deal… my experience is it cost me over 200 to do this about 5 years ago. eagle rods aren't much much and offer a better piece of mind. IMO.

one up side though would be that you don't need to notch the block with LS rods.

I have a local machine shop that did mine for $150 and that included the bushings from crower. LMK

Finish modded ls rod


Ls rod next to d15 rod

I'm not looking to spend that much on the rods, im just trying to make a cheap little build. Also i already have eagle rods and vitara pistons i bought off a local guy for $175 but im want to save those rods for my next build.

Well then good luck with your build. the amount of time it takes to do the machining properly is what adds up the cost. You can't beat the price when you think about the benifits to them.

- 400whp rods
- oem quality
- cost effective

If $150 is to much, not much i can tell ya.

if you can get it for 150. thats a good deal.

if you are shooting for over 300hp I would pony up for eagles, or FJT has made some custom rods to correctly place vitara pitsons.

here are the 2 set ups I have built.

LS rods with SRP pistons / stock z6 rods and pistons


stock z6 rods / Eagle rods with Vitara pistons

i can't remember, but they weren't the lightest things. maybe one of the guys who still have them apart could weigh them?

Why would anyone not spend another 150 to get Eagle rods for 300 shipped from pretty much EVERY dealer in the country? lol

It all comes down to cost vs. nesecity. I do not need eagle's so i went with these rods. Like everythign, you don't need a ball bearing turbo to make 400 whp a journal bearing works fine. But it sure is nice to have a better stuff.

yeah but the price difference there is a lot more than in this case. the $150 for a bulletproof setup seems like it's worth it IMO.

y0, are vitara pistons press-fit...and, what size is the pin on them?

reason i ask is...

in 1999 i built my first D. it was 12.5:1 with spray. i ended up using peened LS rods, but with custom forged pistons. the dummy who i consulted suggested getting the pistons made to accomodate the larger LS .826 (IIRC) small bore.

mistake.

anyway, i wanted to reuse the rods in a later NA build with press-fit pistons and my research showed me several examples of, when the small bore was re-bushed to accomodate the .747 pin of the smaller pistons, the bushing actually rotated in the bore (eventually).

so, i ended up just using peened y8 rods and trashing the idea of re-bushing the LS rods i used previously, but that was ok since i was only NA.

The vitara's are full floating pistons and the wrist pin size is 19mm.

ahh, ok, so normal d-series size @ .747-8

full-floating, that's good. bushed small bore will work just fine for that vs. press-fit.

thanks.

Fu*#in' Honda-Tech, I agree with rota, who the ____ would spend money to mod stock rods for a boosted setup. Get some eagles for fu-ks sake. What are you guys doin'? HMT 4life. lol.

what exactly is being machined on the ls rods to fit the vitara pistons? is it the wrist pin inner diameter to allow floating wrist pins and or the thickness of the rods piston end to fit into the vitara piston? also i heard of people using b16 rods any difference between the two?

the question in this post was about fitting LS rods to vitara's in a d16. to do that you have to:
1. create a bushing for the wristpin (LS wrist pin is bigger than d16/vitara wrist pins)
2. thin down the LS rod around the main bearings, so it fits on the d16 crank (between the counterweights) - you can see this area already machined on the images above.

LS rods are used bc they have the same length as d16 rods. b16 rods would be too short .
I too have heard of people using b16 rods, but that is in conjunction with Supra pistons (over seas model only).
https://honda-tech.com/forums/forced-induction-16/anyone-still-interested-toyota-b16a-hybrid-piston-rod-package-sohc-d-series-engines-267641/

if you're into NA you can find a civic GX (natural gas) d16 and mate it to an LS rod without the bushing, (if memory serves correct) for an High compression sohc.

--

but like everyone said above, spend an extra 150 and get eagles. I did it both ways, and wouldn't do LS rods again. Eagles were less hassle and give me piece of mind.

so for the eagle rods they are just regular d series rods but beefed up of course and no special lengths to keep in mind and they are already floating wrist pin setup perfect for vitara corret. no other mods necessary to install.

but like everyone said above, spend an extra 150 and get eagles. I did it both ways, and wouldn't do LS rods again. Eagles were less hassle and give me piece of mind.

That's the worst analogy possible, a ball bearing turbo isn't more reliable as would an Eagle rod to an OEM cast rod.

This is about reliability and doing things right, instead of a Tial BOV use a DSM to save that 150 bucks or something lol I don't agree all that much with a Vitara piston either but I let that slide usually, but the rods can be used for ages without breaking whereas a stock rod is just that, stock.

http://www.fjdistributors.com/ has vitara pistons and rods for this setup
d-series.org has covered this a bunch of times and many suggest against using ls rods in a d.
