I currently have a greddy turbo kit, and I was wondering if its worth replacing the td04 turbo with something else? What other direct fit turbos would work better with the greddy manifold? I am tuning Megasquirt already and want more power. What injectors would match with a better turbo? thanks

the td04 15g will give you up to around 250-260 rwhp, not much sense in swapping it out just yet.

If you're going to replace the turbo itself you might as well get rid of the mani too... so basically just save for some nice DIY setup.

Get injectors in the 440-550 range, most EMS Miata guys run somewhere in there size-wise regardless of turbo selection.

I would go with a new turbo and mani if you have the engine and drivetrain to support it.
