So i'm trying to shop for fuel components to help build my brothers rx7. I am very inexperienced when it comes to fuel applications for rotary engines. I would like some recommendations for injector sizing, turbo trim, fuel management system etc. The goal HP goal is 350whp for a daily driven turbo rx7. I hope I get amazing recommendations as always.

Hello can you add some more detail like ecu type fuel type, or is that what you are wanting to know, if so there are plug in and wire in types. and that would depend on the car and its wiring condition and what level of build you want to do

Regards Ross

that's what i'm aiming for I do know rotaries have 2 sets of injectors etc. so i'm pretty much looking for a list to do 350 whp safely.

My go to for numbers like that with a LOT of headroom is 2 id1050s in the primary and 2 id1700s in the secondaries. Its overkill but easy. You can probably get away with 1300s in the secondaries but why bother.

Some people will also suggest id750s for the primaries but again, why bother as their resolution is more than adequate to idle properly (and pass california smog for that matter)
