Stock Engine Block?

[dandoyzki]

I am currently building my turbocharged forged 1nzfe engine, replaced pistons and rods with forged ones, used arp bolts and stud kits,

BUT

I am only using the stock block, Can I hit 300 HP with no problems at all? To those who have experience here, What is the safe zone for this?

Thank you

I think a number of people exceeded 300 HP with the stock block. Which rods and pistons did you use?
