> [@SHIFT\_SR20DET](#): > > FC (RX-7) Turbo II’s Fit This is being said, but I can’t see how it is possible. All FC injectors are topfeed. Which means they won’t/shouldn’t fit into the SR/KA. Some Subaru injectors fit. Not all. ---

E - Topfeed D - Sidefeed Both STI and FC Injectors you will need a new rail. The only Injectors that are a direct fit are the SR’s 370’s. ---

I got an Sentra SE-R’s Top-feed fuel rail with MSD 50lb injectors for $106USD off eBay. :bigok: Brand new, the MSD injectors are like $67USD each and the rail is $150USD or something.

> [@Jacky Ngai](#): > > is it bolt on without any problem? thanks! I’ll let you know sometimes next year (Jan-Feb 2005) when I get the actual SR motor. If it isn’t an actual bolt on, I’ll order the one for the SR20DET from the same company ([www.JGYCustoms.com](http://www.JGYCustoms.com)). ---

digging this up… werd on the street is that DSM injectors will work confirmation? what options are there in the 444 - 480CC range? ---

DSM injectors are low impedance (2-3 ohms), while the SR20DET are high impedance (11ohms I believe). You can make them work by increasing resistance on them. I’m no electrical gurul here so I have no clue how to do this. Get your hands on the RX-7 injectors. They will work. I’m not sure how much modificatio is required but it shouldn’t be that much. 1993-1995 FD3S - 550cc/min, ND side-feed primaries, 850cc/min, ND side-feed secondaries ---

gotcha, i dont really want to go with 550cc, thinking 480’s max, so perhaps i’ll hold out for S15 injectors. ---
