New Injector Size Options

[swerve]

Hey guys,

Am chasing a little info on injectors. Turbo install is just around the corner and I am querying the injector setup to run with. From quotes in this forum the standard supra injectors seam to be fine running the ct26 at standard boost, however, when you go up the 12psi the CT26 can put out, they need to be replaced with larger.

Now to the actual question. Is there such a thing as running too large an injector? If I buy new injectors for when I want to run 12psi, will they be too big for the 7psi setup?

That being said, what size injector is required to cope with 12psi. 550cc, larger, smaller?

And finally apart from sourcing injectors from a supra, how do you know what injectors we are looking for. Is there a way of identifying whether a particular injectors will work or is it simply a matter of walking into a shop and saying "I'm after 550cc (or whatever size) injectors for a 5sfe?

Thanks for your help guys, no way I could have gotten this far without you all.
