I have a set of precision pte 1200 injectors in my car. I just got rid of the kinetix ssv plenum, and I'm putting a stock plenum on. But, the stock plenum won't sit all the down on the lower collector, because it is contacting the fuel rails. I have about a 1/2 inch gap. I'm currently using stock rails with -6 AN fittings welded on. So, I am using some spacers to take up the gap left between where the stock rails bolt to the lower collector, because the injectors are longer. Would switching to a set of aftermarket rails solve this issue for me? I have also considered an iso thermal spacer, but I don't think that would fill up the gap from the collector to the lower plenum.

Thanks in advance for any input.

 

Hondata sells a thicker spacer for the vq35de, thicker than the iso thermal spacer...also, I know when I had RC Injectors, I needed bigger spacers and RC provided them...you can see if you can get those...

 

I think I found what I need:http://www.frsport.com/Nissan-350Z-1...r_p_15698.html Thanks to thatv35guy.

350z006, I found that one that hondata makes, I didn't see a measurement for how thick it is.

 

as you have found out, domestic style injectors like the PTE need a plenum spacer.

The one you listed or the one that Dynosty sells for the cosworth also works.
