stock rods with je pistons

[srdub-t]

i know theres lots of theads on this but for some reason i cant find any good answeres. I know the sr rods are pretty good so i was wondering if i can get away with stock rods and je pistons (stock bore and stock compression) bossting like 25 lbs on a gt3071r?

[srdub-t]

bump cuz i know someone knows

Regardless whether they can handle it or not, I would say upgrade, why go half assed when you are dealing with bottom end internals, because you cant just easily upgrade later.

[srdub-t]

but i was thinking that it might not be half a$$ because it might not even be worth it because the pistons im looking at are only good to 500 horse and if the stock rods can handle that then why even bother with other rods?

[redtop91]

The common consensus is that although the stock rods can handle that amount they don't do so very reliably. I'd say that if this is only a weekend or even once monthly racer stick with the stock rods although personally I'd just upgrade them while I was in the block anyways.

so 500 hp on stock rods is defenatly pushin it

[redtop91]

Yeah IIRC Enjuku had their stock internal SR at around 500 and it popped but I don't know if it was a piston or rod that failed. I'm pretty convinced it was a piston failure though.

[homeslicej2]

Yeah, SR pistons will fail before the rods. Enjuku recommends their ER spec rods for 400-450 whp. They have ARP bolts and weight balanced to one another, but are also lightened. I don't know, but personally, I wouldn't use unmodded stock rods at 500 bhp, but that's me.

I have said this before and I will say it again. The pistons will fail before the rod. The rods are short rods and don't see a lot of odd leverage that a longer stroke rod would see.

However, 500 is a grey area for stock rods. I've only seen stock rods used at that power level for determing how much the stock internals can hold.

Most builders replace their rods when they're looking at the 500s.

My suggestion is if you have the money, go ahead and plunk some down on new forged rods. If you don't, you're gonna be playing a game on whether or not the rods will hold. I'd like to say with certainty they would hold, but I unfortunately can't say that.

[homeslicej2]

I was hoping you would chime in. Hey, why'd you change your screen name?

[Hijacker]

I got tired of the old one. I always get blank stares when someone at an event asks me what it means or how to say it I've been using this one on some of my airsoft forums recently, and it fits since I like to hijack threads

I've been wanting to see someone with Brian Crower rods pop up. Those suckers are rated for 750 hp and were reasonably priced last I looked.

[redtop91]

I'll probably be using a set on my rebuild or Pauter if they make SR rods.

[homeslicej2]

Makes sense I guess. I never knew how to pronounce, or what it meant, but I always forgot to ask. Pauter makes SR rods. I look for the site that has them. I've wondered about BC rods too.

[Hijacker]

If I felt that I could justify putting rods in my motor, I would do it. I would probably go with BC because of the rep the company has earned. but given that my power goal are mid 300s, stock rods are more than enough.

My old name was japanese. It was the name of a character from an anime I liked back in college.

[homeslicej2]

^yeah, my goals are only for around 300whp one day, so I'll go with rods similiar to what Enjuku offers. I checked, Pauter doesn't make SR rods. Here's the link to their site.

[redtop91]

Yeah I just got finished looking at that. Oh well. Mazworx uses Manley rods. Anyone have a say in those?

[homeslicej2]

Manley is good stuff too. Mazworx does Enjuku's engine work don't they?

[slik_s13]

i was gonna go with BC rods but. im just gonna stick with my stock rods and get them cryo-ed and shot peened, i still havent decided to weather or not im going to switch out the old bolts to new OE's bolts like you did. decisions.....

[srdub-t]

kinda off subject but i was surfing the net and i came acrosst cosworth headgasket on there website for only $120. Cosworth is a very reputible company, has anyone used there headgasket?

[homeslicej2]

^ Try searching and if you don't come up with anything, make a new thread about it.

[srdub-t]

iv tried searchin, just thought id slip it into this thread

[Hijacker]

This is the first I've heard of Cosworth making a headgasket for SRs. Make sure that it's for the RWD. I could see Cosworth making FWD headgaskets, what with the SE-R racing series and all.

I'm only going the route I'm going because I looked at my power goals, and my goals don't necessitate aftermarket rods. In fact, I'd be rebuilding with stock pistons if I didn't have to overbore the block to clean up some scoring of the cylinder walls.

You have to determine your power goals long before you start buying parts so you can have a plan of attack for the motor.

[slik_s13]

oh yeah thats a must. im not even going for as much power as i wanted to at first when i started the build. i figured i'll get my hands on experince before i go for big #'s. my next build i'll go big but for this one im gonna take it easy make sure i get everything right the first time. i just like the extra assurance thats why im concidering the new bolts.

[RICKDICKULESS]

it's not the rods it's the bolt's i've made 500hp on a stock block
