Is there any truth in this? I'm planning on making major power and this information is leaning me back towards the B-series motors lineup.

So is there any truth in this?

If there is, what has been done to prevent it? Shotpeening? Cryogenically treating it?

No. Honda cranks are awesome. Especially the H22.

 

The weak part of the H22 engine is the rods not the crankshaft.

 

I blew a 2.2 motor and the crank was in perfect condition, everything else was gone.

 

Actually the rods are decent too. Its the ringlands on the pistons that is the weak point.

 

hey guys,

rods are fine, crank is fine, head is fine, like he said, it's the ringlands. Honda uses forged cranks stock. look at all the guys racing with them, and see how many have done anything past balancing them. Not that many. Unlike most domestic cranks which are cast, hondas are forged stock. One thing we don't have to spend a ton of money on, yippee.

That's why for many of us the rod ends egg even with the stock RPM limit... But in any case, the ring lands are also weak, though I haven't heard of many going w/o FI.

 

****** ringlands.. h22 arnt made to rev like those b16s u know

 

of course they are... i just takes a lot of balancing on the bottom end

 

I'm talking our stock rods compared to domestics and d-series, can take quite a bit. Like you turbo guys said the ringlands will go first, I'm guessing the rods are next.

that's something i will never know....... i built my engine before i went turbo, i ddin't get a chance to blow one up on FI first
