I have a rb30 s2 block and head but I was wondering how much power can the standard n/a rods will take before the break? any input will be awsome Some original photos have not been recovered yet.

Allot of people will say it's all in the tune. Maybe 300rw/kw. You'll never know. It also depends on the condition of the shells, rods ect. A decent tuner should be able to pick up any crank noise with their dyno muffs anyway. But I have this saying, do it once, do it properly. It will save any head aches if it does break lol.

cheers; yeah it will be a daily driver/cruiser, all i want is reliable power, and it will have std vlt pistons, around 8-10 psi low mount etc.

People do say 'its all in the tune' but there's still a limit to a part. You could throw a rod on a standard engine, or it could handle 400rwkw, there's no guarantee's. A good tune doesn't mean you can push parts beyond thier limits. ---------- Post added 04-12-10 at 17:04 ---------- Quote: Originally Posted by 2ltrbtu [View Post] cheers; yeah it will be a daily driver/cruiser, all i want is reliable power, and it will have std vlt pistons, around 8-10 psi low mount etc. With that boost, you'll have no problems as you're working well within the limits of the rods.

As above, it could go the first time you plant your foot down or it could last for the next 5+ years.

300rwkw is fairly common on standard internals

I doesnt really matter, standard rods with good rod bolts should go between 350-420rwkw on most dynos without any problems, that around ~130mph. If you bend one, go buy another bottom end for less than $300 and do it again.

awsome I just want a mild build. cheers
