Well WickedIXMR and me had a discussion about building a bottom end using Aluminum rods instead of the heavier H-beam Carrillo rods.

From what I have read, Aluminum rods are better for high revving motors. The rods don't eat up bearing like the Carrillo rods, but the weak point I heard about these rods are that these rods will eventually fail once a lot of miles are put on them.
So from what I have gathered, that Aluminum rods are perfect for high Revving motors that won't see a lot of miles and that will be teared down once a lot of miles is put on the motor.


Also I heard Carrillo rods would be a better choice for street car, mainly because the rods are strong and can hold up to the abuse of high revving. But the fall back is that the rods eat bearings.


Now understand I want ppl who know what they are talking about opinions on this matter.

After I get rid of my Mr2 (hopefully around tax time) I will be starting another project and what ever car I get next I will not be driving it a lot since I have two daily drivers. But because I don't have a tow vehicle, I will be putting on miles getting to and from the track, so I am just trying to figure out what rod would suit me better.

So would it be better to have a Carrillo rod, that the only thing that I would probably have to replace often is the bearing (much easier than rods)? But because of the weight of the rod, I have a better chance of blowing up the bottom end revving it up to 10k rpm

or

Aluminum rods would hold up better to a 10k rev than its heavier counterpart. But I will have to take apart the bottom end after so many miles of hard driving to replace the rods.

If anything I said is not true, plz bring it to light
