The SR20DET uses high-impedance (11ohm I believe) side-feed injectors. Will high impedance (12ohm) top-feed MSD injectors, along with an aftermarket top-feed fuel rail designed for the Nissan Sentra SE-R (with the SR20 motor) be compatible with the RWD SR20DET red/blacktop? I am sure the injectors will work seeing they are the correct resistance but will the fuel rail work fit up correctly? Just need some affirmation on the two (injectors and rail). ---

I checked that fuel rail off that NX2000 with the SR20DE and its Identical to the Blacktop’s SR20DET. So by that I would have to say they are the same. ---

i got one from a yard to install onto mine to fix where it was bent and, it is not exact for the redtop, the space between them is the same, but where it mounts to the intake the FPR is on the other side and only 3 of the 4 bolts match up. it could probably work, but it wasn’t enough for me. ---

OT: I have a sr20det fuel rail in my garadge if anyone wants it. You just have to pick it up for pay for the shipping +$2 for my gas 🙂 Maybe you could grab it G and use it for comparisons. ---

Hrm, I wonder if any of you misunderstood me. What I wanted to know specifically is are the mounting points, as well as location of all injectors exactly positioned as those on the SR20 Sentra motor. Because I won’t be using a stock SR20 rail; I will be using topfeed injectors which require an aftermarket rail and I have a chance to get an aftermarket top-feed rail that is made for the Sentra SE-R. In anycase, I did e-mail the company that made it and they said it will work. ---
