Hi guys,

Going to buy a Greddy plenum for the RB25 for simplicity of pipe work. In addition to my list below, what is involved in changing the plenum?

New gasket

Throttle cable modification (any recommendations?)

Throttle body adaptor

Water and vacum line extension?

Cheers

hey gtst89, i will also be doing the same sometime in dec (will be doing it with fmic) with the Throttle body adaptor u can buy the kit with the plenum to suit the r33 rb25, or else i belived a Q45 throttle body will fit perfectly.

Water and vacim lines, if need to be extened is easy as going to buy the lines from autoshop (i guess it is the same stuff i use when i did my ebc)

I am also interested in the throttle cable mods :confused:

cheers mike

You have to either make up a Throttle bracket and get a longer throttle cable, I have found going to a wreckers yard and getting an older model Nissan pintara cable works great. You also have to extend to connectors as they don't reach under the plenum to connect onto things like the AAC valve, so if you’re experienced in extending connections that shouldn't be a problem. Vacuum and water lines, only need to be trimmed up to fit. They are simple. Apart from that, theirs nothing else really to it.
