Have a look at the RB25 dyno results page and see what mods people are running to achieve your power goals -

You're not going to do it with either of those. Injectors too small (and too old and shitty). Coils are shit. Upgrade to at least Splitfire, if not Yaris coils or R35 type coils.

Fuel pump is probably too small too.

if 500whp (373kw) is truly your goal, your fuel choice also matters which can affect the turbo you choose to run.

As far as ECU's go, find one that your tuner will tune.
No one does or trusts online tunes for cars like these. They're pushed too hard and are too individual (even with same list of mods) to get anywhere close to trusting a tune from another car.

You'd need so much gear to convince yourself the tune is actually okay, to the point where you could just DIY the tune from that point.

All fail whale items, please don't get any of them.
