I agree - Toyota engines are notoriously under tuned in favor of reliability.
MWR sells high comp 12:1 pistons and forged rods as well as upgraded valve springs and seats. My plan next year is to wire in a standalone ECU so I can run my engine on 93 octane pump gas and slightly increase the rev limit. Once that baseline is established then a bottom end build would be in order with a 12:1 compression and an 8k rev limit. At that point I would hope the 2zr would make around 180hp but I don't really have anything to go off of to have a realistic idea what it could reliably make.
