which injectors when going aftrmrkt manifold?

[Iknowthefuture]

With aftermarket manifolds and fuel rails, iirc it says 10.5 or 11mm injectors top feed.

I have my eye on 750cc DEATSCHWERKS Injectors for the RB20DET. is that what i can use?

Will rb20 specific fit? rb26? any insight.

I couldn't find a thread so maybe somone else might be wondering too.

I used my stock fuel rail with Deno injectors.

It really depends on the type of fuel rail you are switching up to. You have to cater to the rail itself. If you are able to fit your stockers in it, then stock style upgraded injectors should fit too. For reference, nissan style top feed injectors fit in 10.5-11mm top feed rails. You just have to make sure not to get nissan style low impendance injectors (RB26) since the RB20 uses high impendance injectors. Stock sized injectors are better fitted for 10.5mm. I have found the need for a thicker O-ring to make them work in a 11mm rail in some cases.

you can use low impedance injectors just fine. you just need a resistor box

If you decide to go with a rail that has the bigger 14mm port, I should still be able to find an injector for you that will fit.

its a combination of rail and intake manifold, the rb20 uses top feed high impedence, if u can get those from DW they are drop in and just need a tune, if u go with gtr top feed low impedencce u need to wire in a resistor which is not that bad but its still something that needs to be done and is not too hard but its not simple either, your other and final choice would be to use side feed inj which is completely a** backwards and makes no sense, more than likely the rail your using has like 10.5 which is oem size, for simplicity i would get inj that size, and if u want to use an fittings get a top feed rail but make sure its 10.5 DO NOT buy those dual rails they are peices of s***
