Okay so far I have a compression issue for one cylinder. It appears to be the rings, as I put a tiny bit of oil in the cylinder to check and sho’nuff it came up.
so…
Ima buy some pistons (probably the wiseco 12:1 set) along with some cams and dual coil springs, but I don’t wanna put a whole bunch of hp through on some stock rods. Yea b17 rods are pretty strong to start but ehhh they’re stock heavier than necessary and old…very old… lol.
So I want to pop some rods in there. I’ve found 2 companies that I know for sure will make rods for it: Crower ($762) and Pauter ($950~)
I know you get what you pay for, but I am not aiming for anywhere near the horse power they’re said to be stable up to… I would like to get some eagle h-beams but so far have been unable to verify either way if the do or do not make them. I have found 2 websites claiming to carry them but cannot find a part number listed. I’ve looked through eagles catalogs and haven’t been able to find any that even have the same dimensions…
HELP!!!111
I need to know if eagle makes rods for a b17a or if someone else does that doesn’t cost an a$$load!!?! :uhoh:

i thought that the b16 rods were the same as the b17 rods. just a slight difference in height and stuff, and the crankshaft was a bit diff but we ain’t talking about the crankshafts.
nothing wrong with going with b16 aftermarket rods. if i’m wrong ppl can correct me on that.
I’ve gone through numerous forum posts and seen this quite a few times and have seen it being corrected. The b17 rods are quite enough different that going with the higher compression pistons it could be catastrophic. I’ve got the exact measurements:

??? maybe u misunderstood me. UPGRADED eagle rods that are for the b16 or b18c could be an option. catastrophic would be if u did all this raising of the compression and never took the motor to a tuner and ran on 87 octane.
a slightly different length rod wouldn’t change your compression much (if any), it would affect the stroke. obviously if it didn’t go as high as a b17 rod the compression would just be slightly less than it would if u did have a b17 rod. shotpeening ur b17 rods and getting them knife-edged can do lots for them too. some arp rod bolts are a must too.
[QUOTE=teggyguy;2037705]Yes I definitely was considering a shot peen and knife.
So you’re saying that you think the b16 rods will fit the crank for the b17? What about the bearings would those need to be different?
ARP is DEFINITELY a must! lol
Got the head studs already
Do you know anyone that does reputable shot-peening? What’s the $ amount for that?
Looks like the b16 rods are about 4mm longer.[/QUOTE]
ok at least u figured out whether they are longer or not. b17 rods..... *thinks* i know other rods can fit, whether they fit ur crankshaft depends on bore that end of the connecting rod. so a dial bore gauge and mic will come in handy.... or some plastigage (a whole lot cheaper). but mic and dial bore gage is what is very accurate.
regarding shotpeening....... doesn't golden eagle do that? i believe most machine shops have that capability. and same goes for the knife-edging. i'd look for a local machine shop and inquire with them to get real quotes.
i remember reading an article in honda tuning or super street or something where they built a b16 turbo with up to about 500+ hp. i know its not that big of a deal, but they built it on a stock block EXCEPT for the piston cuz there was no way in hell a stock piston was gonna be able to handle that. but they wanted to prove that a b16 with stock rods with arp rod bolts was gonna be able to hold and perform when mated with a built head and forged pistons on a turbo build.
it was proven and everything BUT the amount of time they spent on tuning will burn a hole in ur wallet. they had to up everything in such small increments so that they did not detonate and also so that the stress on the motor could be controlled and minimized. but they were able to do it. so if anything i say shotpeen urs, get it all done if anything and u’ll be able to maintain the use of ur rods, and make sure u keep them in the right order so that u dont’ have to worry about which spot it goes into on the crankshaft. then u can just replace the bearings, to get the right clearances that u want and need.
I personally wouldn’t upgrade the rods unless you’re going turbo. The stock rods will be fine on an NA engine.
Changing rod length will not change stroke. Stroke is dictated by the crankshaft. You do not want to change the length of the rod, unless you REALLY know what you’re doing you’re going to get yourself into all types of trouble.
Shot peening is a good idea, but it doesn’t do a lot. Knife edge a rod? Never heard of that. Only heard of knife edging a crank. Which is something you don’t need to do. In fact many people recommend that you DO NOT do it as you could run into unfavorable results. Balancing the whole rotating assembly is plenty good.
Teggyguy, what are you building this engine for? Is this your street car? A race car? A drag car? A track car? 12:1 is very high. You’re not going to get it to run well on pump gas with a compression that high. Have you done the research on the things you’ll want if you ran that high of compression? (appropriate cams, headwork, upgraded intake manifold, exhaust manifold, exhaust and extensive tuning)
lol knife edgeing i thought was possible too on the rods. not too sure on it but i thought i saw it being done or something. i could be wrong tho. but maybe i can find something about it. i had a SUPER old issue of hondatuning back then where they did the frankenstein killer b-series issue. where it went thru basically everything u need to know about building a bseries (short version).
reason i didn’t bother asking what this guy is gonna do with some high ass 12:1 compression pistons is cuz i’m actually curious which one of these guys will actually go thru with it… cuz its ridiculously high for street use. even for track use, u gotta have some really good pump gas or start dumping in some race gas.
and ps, i found some crower rods for the b17, but its 710+shipping, so kinda in the same ball park.
x2 on what colin said. no need to upgrade the rods if your staying n/a. the stock rods are very strong. and stock pistons will also be fine and you can choose what compression you want staying oem. type r, b16, jdm or usdm will give you different compression ratios while staying fairly on the cheap side.
Heh yeah 12:1 is some high ass compression for sure…
Luckily my effective here in colorado is going to be somewhat less than the said static (calculated through the volumetric information available)
Nearly 1 whole 1:1 ratio less.
Either way, I do eventually plan on doing boost and thus why I decided to move the new rods in now anyways. I think I’m going to check the reviews on the endyn bumpstix and see if they have something good for my application. ATM I have p73-00 pistons in her, but considering the prices on rings I figured it’d be better to just upgrade anyways. I do plan on running a s300 with a wideband and tuning it up.
Currently I have
Titanium retainers.
Type-r springs and valves.
Type-r Intake manifold.
DC Sports 4-2-1 header (going to go when I do this build)
JDM-r cams
JDM-r pistons
Balanced/Polished crank
Aem shortram (may go full cold air if the weather ever changes)
Milled head like .002" i believe
And thats about it for motor…

umm ok. yea u denver guys have to deal with a bit more complication with ur higher elevation but i didn’t think it was that bad. but u said u eventually plan on going boost but do u plan on doing that on those pistons wiseco 12.5:1 pistons? cuz that raises a flag in my head.
but regarding those pistons tho… someone correct me if i’m wrong, but wont machining be required to put these on b17 rods? i know he said he wants to get new rods. but will it be required to be done on aftermarket b17 rods as well to get them pistons onto them? i just wanna verify it so i ask that on my behalf.
LOL! Yea I did say I plan on boosting. Those pistons will not be used in that case though. I know the static vs. effective and the maths for that. The most I’d run static when boosting would be 10:1 (which is high I know, but I prefer the high cr low boost, i know it requires more tuning)
Per the wiseco’s mounting to the rods the rep at wiseco didn’t say anything about that. The compression to motor is 11.5:1 - 12:1 according to their catalog.
I just talked to endyn and apparently I can get custom pistons and pop those on the b16 rods for the same effect. So I may not go the same direction. Luckily I can’t loose much on those wiseco’s anyways and I have a couple people that would probably buy them from me here in town too so either way, I can get the b16 rods for a couple bills and the custom pistons and go that way (just need to get a quote to decide).
Per the rods I’m still waiting to hear from eagle. Endyn does custom rods but they’d be from crower so still in that boat =|
Bloody b17’s lol. I hope that I can get the rods situation taken care of soon.

i hear ya. i think thats why most ppl take their b17’s and go n/a. considering it probably has the best r/s ratio that is well balanced n everything. lots of praise regarding the crank too. i’d love to get a gsr later down the road, but i wanna start from stock and build it up instead of have it already be modified.
The crank from what I heard is as good if not better than the type-r crank.
What I may do is grab up some eagle h-beams for the b16 and go with the roller wave pistons. I can go that route and then I can boost down the road too, I’d have to have another set of custom pistons made, or I might just stick with the high cr na build and call it good and but a b18c for the boost stuff…or I could buy a b18a (like a 93 rs or something) and buy the ls/v head from endyn and go with a boosted ls/v beast hehe…
Alright so I have a VOTE:
stick with the wiseco’s and stock rods or buy the b16a rods and sell my wisecos and buy roller waves from endyn that are custom.

Wiseco 12:1 piston kit
Crower perfomance rods
