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.

    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
    • I'm interested,do you still have it?
