Maybe this has been asked before, but here it goes. Can the silvia injectors be used without any mods to wiring harness, such as resistors with a stock modified b-13 ecu? The fuel injector seems to be same type used in the fwd models as it is not a top feed, but a galley fed injector! Seems to be more options for RWD sr20 as far as injectors. I have nothing against msd, but a company like DENSO who makes oem injectors seems more reputable. Thanx for the inputs!:D

Stock Silvia (also 300zx, q45) injectors are a common low boost upgrade. You can use any larger injector for the silvia as well. However you will find that most of the side feed upgrades are more expensive than the MSD's AND the rail cost. I myself don't like the look of the rail and opted to go with Apexi 550cc injectors and Nismo adjustable fuel pressure regulator. The only Silvia injector upgrade I don't recommend is the Tomei, they are side feeds, but required their installation kit as the injector does not just fit into the rail. It is a PITA to install. The Nismo regulator basically looks like a stock regulator with an adjustment srew on top. These regulators can be purchased from Andreas. Hope this helps!
