Reuse A Conrod

[itshimdazza]

Guys,

I believe that I may of crackedd/broken a conrod in my R33 GTST SII. Now I have a question as I have a friend that had some forged conrods that have been used (for about 4000Km's).

Now my question being not very mecahanical but can you reuse conrods (even if that are forged) in another engine?

Hopefully you can give me some worldly advise..

cheers,

Darren.

If they have the correct dimensions and are not damaged, there is no reason why this couldn't be done.

depends on the price.

they can be reused... but when GTR rods, for less than $400 - will hold over 400rwkw... forged rods are a waste of coin.

I wouldn't use 1 rod of another design. Your first problem is the static mass of the rod/piston combo. You always want them all matched throughout the motor and it may not be possible to shed enough mass of that 1 or the other 5 to get them even. The other thing is that the centre of mass may also be different depending on where the weight is in the rod which may lead to other engine balance problems with harmonics.

I would say that if it is a visually different looking rod and/or it weighed a different amount do not use it.

Well I can get them close to $320 , i believe their worth close to $600..(new)

Also i have another question that if 1 of my conrods is broken do you just swap that one or do you do all 6 at the same time?

all 6 if using a different brand/model

just one if you are direct replacing
