Hi everyone, okay so the story is I’m going to put a holset hx32/35 hybrid top mount on my rb25det NEO. Got most if not all parts/supporting mods ready. I bought injectors for R35/350z fitment a while ago (Before I bought plenum and rail) as they are top feed and fit the NEO....But I would very much like a Front facing plenum as it completes the looks, I know you don’t gain performance with the greddy knock off but this thread isn’t to debate that. FFP is mainly for looks and easier access to maintenance & repairs. Anyway... here is a pic with the injectors fully seated. It looks that they are too far back. They look recessed by about half an inch? I haven’t fitted these front plenums before. But this doesn’t look right? Surely the injector must be further in towards the front of plenum/mating face area? Secondly, are the supposed to fit inside the first hole in the rail? Because it doesn’t. It’s not a snug fit. It’s very loose. I bought a 419 piece o ring set off eBay and surprise not one of the o rings fit inside the rail. I guess I will need to take injectors and rail to o ring specialist and get some? Picture 3 is with another o ring on the injector, pic 5 is without second o ring fully pressed into the rail. In the meantime I’m just going to run standard rail and standard injectors on the greddy knock off manilfold. If anyone has done this setup before or similar situation please any info will be greatly appreciated. Rory.
