OK so I've searched about the injectors but dont rly know where to start for the turbo. Whats the step up turbo upgrade for the RB25? Like the SR has has the s15 turbo or I guess GT2871R, whats the next step up for the RB25? Also, if there's not rly a turbo like that is there anywhere I can get injectors for an RB25 below 500cc's? Nismo 555cc's are the smallest I can find, will supra or RB26 injectors fit?

What are your hp goals? That will dictate what turbo you'll want to "step up" to. And why are you set on injectors below 500cc?

350-400whp but if not I want just slightly larger injectors so I can push it farther on the stock turbo.

S15 injectors are 480cc and sidefeed, that's a possible.
