im actually PMing a member about a set of sard 850's. i really dont like to buy used items that i cant test, but they supposedly have only 5k miles and collars/plugs for 315$. If i buy used injectors should i send them to get cleaned before i run them

Wouldn't hurt, but by the time you spend the money to get them flow tested and cleaned you could've had a new set. I have an install guide for Sards into a factory rail as well. I can't remember if it's on this site or Tamparacing.com. My Sn is the same on both.

Anyway, I recommend the Sards because they have a better design than the Tomei/Nismo units. Larger windings for increased control, better spray pattern and a lower lag/dead band. You can get your engine to idle better and smoother even though they are larger cc injectors. Generally speaking the higher the cc an injector is, the harder it is to get a smooth idle with them.

He is speaking about my injectors. DW are crap injectors, they have a high rate of failure. I am also on Tamparacing.com ( Super Coupe)

Anyways, I can send you a video of my car if it means anything constant idle, stays within .5 with a enthalpy rom tune. Car has seen 30 psi on a HX40 with no issues. They were used on my previous car when they were new, before I put them on my current car I had them checked by witchhunter, they were all perfect. Still had them cleaned and freshened up with new o rings, and caps. All of them OHM exactly to spec also.

If you are worried about installing them, I could possibly give you my rail with them already installed as I am going top feeds. Only thing I would be worried about is fuel leaking out during shipping, obviously I would do my best to get it all out.

Also no you cannot use the pins from your stock harness. Tried that, they are different. I am giving you clips that actually "clip" into place. Very easy to solder the clips into your harness. Just connect the two wires per injector and you are good go. If you are scared to do that you don't need to be modifying cars. Keep your old clips with a pigtail, if you ever sell them and go back stock you have those to wire in. Takes 20 min tops, big deal. Most injectors require you to wire in new clips anyways, sometimes even resistors if they are low z.

I don't deal in crap parts! My injectors are ready to make power, tighten down rail, wire clips, ride out.


Yes, if you go ID 1000's you will spend quite a bit more money. But it all comes down to what you want to spend. I myself, once I sell these injectors will most likely be picking up ID 2000's for more power.
