How to get around 500bhp from my rb26dett R34?

[c20let2k]

My stock turbos have seen better days now and i'm gonna upgrade thows with new reinforced garrett's.

These are good for around 600bhp, and i want's to see about 500bhp from my rb26dett r34.

What injectors do i need? Is it low og high impedance?Will i need a new fuelpump?

I have the basics as big exhaust, hks boost controller, hks airfilter mod and so on..

What more do i need?

These turbo's i'm going for:

ECU... any stand alone (Power FC, AEM, etc.) or going with a Rom Tune will need to be addressed.

Injectors, 700cc+ will be a good range for you to look into to keep head room on duty cycle. Add an adjustable fuel pressure regulator to that as well.

Fuel Pump... assuming this is a R34 GTR, I don't know the strength of their stock pump so I'll leave that upto someone else.

I have this piggyback unit, stand alone or something i think..It's a R34 GT-R V-Spec yes.

Will the engine be reaible with this sort of power?Did change my clutch this summer, so that will last..

Hans (HxC_Nismo) on here has been at those levels with mild upgrades, he'll chime in hopefully. But with the proper tune you shouldn't run into issues.
