ktm Posted May 19, 2007 Share Posted May 19, 2007 I have a set of the 440cc Supra turbo injectors. I am nearing the completion of my engine build and I test fit the injectors in the manifold. The injectors ends fit into the ports in the intake without the o-ring installed. However, if I put the stock o-ring on the injector end, the o-ring seats itself outside the port. My question is should the end of the injector slide into the manifold port with the o-ring attached? The end of the injector is larger than the OE pintle cap. Thanks.

trippintl0 Posted May 26, 2007 Share Posted May 26, 2007 i removed the supra o-rings and installed the stock 280zx o-rings onto my supra injectors, and it fit in there, if i remember correctly.. although it has been a while. Yes, I don't think it will slide into the hole where the pintle caps originally go. Quote Link to comment Share on other sites More sharing options...

Yes, I don't think it will slide into the hole where the pintle caps originally go. I did the same with my supra injectors. I am running a Pallnet O ring fuel rail. It all is working great.. I am running the non turbo 311 injectors. But once I go Megasquirt I will switch over to my 440 turbo injectors. Quote Link to comment Share on other sites More sharing options...
ktm Posted May 28, 2007 Author Share Posted May 28, 2007 My mistake on this one. I had the wrong o-rings on the injectors. As soon as I replaced the o-rings with the correct set the injectors seated correctly. Thanks for the replies. Quote Link to comment Share on other sites More sharing options...
