So I have been doing research on this but can't find a definitive answer as to how high I can safely rev a b20v setup like mine. From what I have read some say not to take it past around 7k because the b20 can't handle more than that. Others say they take it to 9K no problem. But all this is on a stock block. I'm running ycp high comp pistons and arp rod bolts with a stock b20 crank and stock b16 head on oem head bolts. I had a nice gsr head ported and polished with skunk2 cams when I was building the block, but something came up and had to sell 😭😭 but that's a story for another day. I'm currently revving to 8k, not really trying to go past that for now, just wanting to know if I can keep doing this SAFELY. I know best way to figure out where I stop making power is a tune, which I will be getting hopefully in about 2 months after I get some cams. For now just want to know if 8k is safe.

 

From what I've seen and read, 8k should be fine with arp rod bolts in the bottom. But you might wait for somebody that owns a b20v to chime in, just to be certain.

 

Thanks for the reply! Iv read a lot of posts about this but haven't been able to get a clear answer from someone who actually runs a b20v. Maybe my searching sucks but I'm trying
