My question is exactly that.

 

Not sure exactly but I have seen LS and B20 motors take 9K with no problems!

 

Thats a pretty vague question...Boost? Rpms? What?

 

I take my LSVTEC to 8k with those rods and bolts.

I would guess to say rpms! As for rods, I believe they are good for 300whp, anything above that should be stronger.

 

Im building a NA LS Vtec. Its going to have a revlimiter or no more than 8800. Im using the skunk2 stage 1 cams. Im looking to make around 190 so WHP. Sparkracing.com sells forged I beam and H beam rods for like $220 with 9mm ARP rod bolts. What should I do. I dont want to buy the forged rods if I dont have to. But then again I dont want to have to worry if the stock will hold.

 

Mine have see 8.5k every pass at 11.5:1 CR. Now I hope they are ready for more.

 

Is yours a daily driver? Im using type R pistons with a GSR head should be around 11:1. I just dont want to snap a rod and have complete engine failure.

What about your rod bolts? Stock or ARP or other?

 

Anyone know how much the Skunk2 stage 1s make power to? I dont think there that much more agressive than the CTR cams. There was a dyno of a LS vtec setup similar to mine and didnt make power after 7800. So I dont think ill be revving over 8400 or so. How reliable would the stock rods be then ?(with arp bolts) Thanks J

 

just fine, thats about stock redline right

Do you have any 1/4 mile times?

stock redline on a ls block is like 6700, but i have taken my old motor to 8-8.5 many times a week. also i forgot to shift one time and i don't have a rev limitor it went for real to 9700 or maybe alittle higher, it sounded so bad and i was so scared but nothing happened. however i do not expect anyone to repeat this stupid almost deadly mistake.

oh yeah all stock bottom end

Fuel cutoff is 7200.

 

you are right i was guessing but i knew it wasn't that much higher then 7000

 

bump

 

anyone else?

 

No one will be able to give you a definitive answer on this. Only "i used LS rods and took it to xxx rpm and i was making xxx hp."

I would PERSONALLY not go past 240-250whp NA or otherwise with them in, and this is assuming you HAVE arp rod bolts.

 

people tend to forget that honda's are over-engineered..... i take my ls rods with arp rod bolts to 8500-9k daily....

 

Alright im going to order the ARP bolts and have them installed then. Im looking to make between 190-210 WHP on my LSVTEC. So I should be good and no more than 9k rpms.
Thanks alot Jay

 

my ls rods with arp rod bolts held 10000 rpm all motor 200whp and aprox 370whp at 8000rpm with 200 shot, ended up breaking a rod with the nitrous though.

 

Well I think the LS rods are rated for 250 hp, any higher and aftermarket is recommended

 

Were these in daily drivers and how long did they last like that?

yes I remember reading an article a long time ago, Im talking 97 - 98, about how you can use LS rods in a D-series motor b/c they are stronger than the D-series rods and are recommended for turbo applications that do not exceed 250whp.

I know a few ppl that tried this and never had a problem. The Rods are not he weak link in the LS/B20 Bottom end, its the rod bolts!
