Water injection worth it?

[mr2turbored]

I'm about to install a 2D system to my mr2 turbo. I've got it to help with det control and help lower the intake temps as much as possible. Still deciding were to place the jets as i'm still learning about the effects.

But for now i'm about to install the Kit with the car running 0.9 bar on a GT28rs turbocharger. I know this is a future mod but will installing this modification now create a noticable power gain?

I know this is a silly question as its a future mod and won't really be needed until after my engine building and alot more boost. Just getting curious to what it'll be like when i fit it now.

And i know, someones going to just say, stop asking questions, fit it and find out. lol

Thanks
