I think you will find that the RB25 is a crossover plenum as well. The RB26 is the one that is forward facing. People have installed these plenum's without much success in a peformance increase

Cheers,

unless u are making big power (300rwkw) and yr plenum become a restriction,

u will LOST power by doing it, and it WILL not improve (maybe decrease) throttle response as well.

as stock plenum has the most even air flow by placing in the mid of all cylinder.

the reason GTR using it because GTR has muti throttle body

    • Ultimately, if the tip is not far into the runner and the o-ring seals, then you are in business. Have you applied pressure to it as is? It is not really a problem for the injector to twist once it is bolted down, the oring seals it and you don't want it jambed into the oring too hard The plenum is intended to take multiple size lower injectors with different adapters, but the way you have it is fine if they seal.
    • Are these the Dmax ones you are in reference too? https://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35#description Not a bad idea to get the uni flange ones. I have sent just jap an email too. Will see what they say lmao. Only thing is the Dmax ones are on a big back order. Low key anything will be better then my OEM ones I got as they are sounding like popcorn when I go under load lmao 😂☠️🪦.
    • They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.
    • Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....
    • Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)
