building a b18c1 pretty much for street dailydriver.
block i aquired had no rods, so i got from another gsr.
i dont see going past 9000rpm, maybe 85-8700rpm.
basically what i have is type-r internals( valtrain-cams,etc).

will shot peening polishing be necassary or these rods plenty strong for that type of rpm?
i do want to get them balanced at the least, i hear important to do.

any posts or feedback welcome.
thanx

 

Shot peening is the very least you should do if you're planning on going up to 8500-8700 range. Let's look at it this way, ITRs have a red line of 9000rpm, but don't use stock GSR rods right? The ITR rods are shot peened from the factory for that purpose, to take out stress lines that could cause them to fail at such high rpm. So you should get the stock GSR rods shot peen at the minimum or you can acquire a set of ITR rods, which btw I have for sale if you're interested *shameless sale plug*

Here is what the stock GSR rods looks like after going up to 9000 repeatedly.

ok
thanx
just wanted to ask see what peoples think
good pics, ill take your advice on that.

 

gsr rods can easily sustain high rpm.
i would recommend you have them balanced.

the rods in those pictures didnt fail from rpm, they had other issues as indicated
by all the heat they absorbed.

 

That is correct,

Loss of oil, oil deprevation, led to spun bearing, led to heat stress, led to rod bearing giving out. Here are the rest of the bearings:

Sorry to hijack your thread, but I'm in the same boat as you, bought a B18C block with no pistons rods. Just wanted to bring up, before you buy some new pistons you should make sure the bore on those cylinders are good. Since I don't know how mine was run prior to buying it, I'm going to do a light 20 over on it. GL.

 

plenty strong , good.
yeah balancing for sure i want done. thanx(sgt)

jcda6-loss of oil & 9000rpm, so thats what happened.
just curious? failed oil pump or?
thanx

 

was already bored/honed when i got it(50over).
but yes, same thought even so, for my own sake, i will check it anyway.
thanx

 

It was actually my fault....the machine shop that did the job wasn't very meticulous and overbore the walls...from the first start up, the car puffed smoke, even after my careful break in. I've had to put 1 quart of oil every 2 weeks. There was a period of two weeks where I had negelected to check the oil level and drove to work. Sure enough, there wasn't enough oil and the engine basically grind to a haul. Lesson to be learned: take the block to someone who's very rebutable and knows Honda engines.

What about polishing the rods? I've been thinking about doing this to help relieve some of the stress points and insure that I've got a little extra strength. No one in my area seems to shot peen rods.... I live in a black hole, no wait it's just Idaho!

 

I have GSR rods if you need them. Plenty strong. Also have standard bore GSR pistons. I run Eagle and Crower rods on my engines, but I am paranoid about engine failure. Stock GSR rods are more than adequate for most N/A applications.
