heya,

jus wondering what the size of a std rb25 throttle body is?

would adding a larger plenum and larger throttle body to a mild rb25 (zorst, fmic, pod, boost) have a positive effect on performance or would it make a negative effect given it is running the small std snail?

cheers!

I think the throttle body is 75mm

I recently wanted a xf throttle body put on but found out its not much bigger

I had the standard one shaved inside to make it larger and shaved the fin aswell so that when its wide open there is minimal restriction

As for the plenum, do it! I had a custom one made at about 6.5litres, as compared to the standard being about 1.5litre

The plenum makes yyour cooler piping about 1.5meters shorter, therefore the air gets there quicker and has less time to heat up

I run the standard turbo, my custom plenum made it alot more responsive

      some days eh? The keyless entry and interior light on/off with the key will be controlled by the Body Control Module, but I'm not certain where that is or what it looks like (you might get lucky with a search to get a part#, which could be printed on it). I'd start at the A pillar/ Under dash/kick panel on the driver's side

      It might be hit and miss, but Nissan Genuine Parts and Pitworks are not the same thing, although both are available from Nissan Dealers with Nissan Part Numbers. Nissan Genuine Parts are the OEM stuff, Pitworks are their attempt to get people back from generic parts makers

      I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.

      Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too.
