Lift?

[Kirk5691]

I'm sure this question has been asked before, but it never hurts to ask again. Has anyone found a way to move the lift point? I would like to move the power band lower in the rpm range. Being an old duffer I have in the past advanced or retarded camshafts to fine tune an engine combination or create more top end or low end power. I'm assuming that with the 2zz this is done electronically. Can it be moved around electronically? If so how? Are there aftermarket cams that accomplish this? Or, you can tell me it cost too many $$$ and I should shove a Honda V6 under the hood. Thanks for your help and hilarious comments in advance.

I'm far from an expert, but I do recall reading that you can use the earlier computer and re-pin it. This gives lower RPM activation. Someone with more tech exp than me will know.

the 2003 vibe GT has the lowest lift engagement point of any of the models. I think yours is already at the lowest stock engagement point since it's a 2003. The only other way that I've found to change the engagement point would be an aftermarket ECU. Call https://www.ddperformanceresearch.com/ and see what they say.

Thank you for the tips, especially the dd performance info.

If you set it to a low enough point, you will damage your performance. You need an aftermarket computer to change it. I know multiple ones can do it, but usually you're looking to spend at least $1000 on a stand-alone, then probably another $400-800 on dynotuning to make sure you don't go too low.

Ideally you'd want lift to engage at the "crossover" point: the speed where output is equal with or without lift.
Toyota probably can't set it that low because of emissions; the greater valve overlap would result in excessive HC at lower RPMs.
