You guys are making 500whp on that?! That looks like the same size as a QR25DE rod! The piston has a very thin top ring land too.. I think I'll be building the engine before putting it back together..

They're thin but they get it done. A few people have bigger rods in the vq30, but the majic is using the vq35 and the parts made for the 350z.

I'll take "What is rod ratio?" FTW Alex.

Hey I got some custom Arias pistons ill sell yea for the VQ30 very stout and nice.

I was surprised at how small the rods are... the other thing is the small diameter rod bearings.. a smaller bearing is more prone to spin under a big load.. or high RPM. I know the rod/stroke ratio is good.. but still.. the rods are TINY! I guess I could toss in the stock block, and see what it'll hold.. I have a few VQ30's sitting here anyway..

I've had a TON of problems with Arias.. in the past year, we had 4 sets of pistons with problems due to manufacturing. I've switched to CP.. and haven't looked back. I was trying to avoid building a block.. but if I have to I will do it eventually.

I always figured that since the power is divided up on 6 pistons/rods instead of 4 that each one sees less load therefore making the skinny rod less of an issue. Is this theory correct? By this thinking then a V8 would be just that much better, even if the displacement was the same.

Scrawny rods and thin piston ring lands (relatively speaking) are really only a problem if you have detonation issues. Avoid detonation and you can get away with a lot.

Yeah I was amazed to see they were skinny when I dropped my Upper-Oil Pan. You would think they would bend easily under boost.

Heck, they are still strong considering the size. They almost look Forged a bit.

Nissan sure may durable motors.

Its not the size of the rod.. Its how you use it!

+1 to that look at all the guys that crack the ford 302 block in half with stock internals its proboly the most common problem once over 500whp mark on a good tune
