I thought it was the other way around - you can put the plenum/multiple throttle bodies onto the manifold if you drill some extra holes for mounting. That'd be a lot easier than drilling holes into the head.

just get a custom front facing or greddy plenum and run a 90mm throttle - it'd be alot easier and probably around the same money. Just look up JimX's custom front facing intake photos

oh, and nice to see a few more ppl from skylines stockholm joining us on the forums! welcome! :)

Hi guys, the RB26 inlet system goes..................

plenum > throttle bodies > inlet manifold > head.

The RB26 head has different bolt patterns, port sizes and water jacket spacing to a RB25 head. So the RB26 inlet manifold won't fit on an RB25 head.

If you want to know more, there are thousands of previous posts on this subject, do a search.

Hmm too bad cus the complete intake with plenium, throttlebodies and inled manifold just lie to no use in the garage. thougt i it would fit i could get rid of that stupid piping straigth over the engine an turbo..

but will the RB26 throttle bodies fit the RB25 Inlet manifold then..

Desperate to get down the intake temp. it's now really high.

and sorry searched but could just find that the GTR plenium wouldn't fit nothing more specific.

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      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.
