Balance Pipe Manifolds On Rb26

Just did some back to back testing on our car with HKS low-mount balance pipe manifolds.

Our car runs HKS GT-RS turbos and the car suffered from the dreaded turbo shuffle. This is not a problem when racing but on the street it made the car really frustrating to drive. As the car started to build boost it would 'choof' its head off.

Replaced the HKS twin low mount manifolds with the balance pipe items and 'hey presto' problem is completely gone. The car is a lot more streetable and driving on the road is now a lot less hassle.

But....

It seems to have softened the car up a little, not coming on boost as hard and appears to have lost a little bit of power overall. Will be dynoing the car on friday to see if my observations are correct.

id say the shuffling is as GTR said is from the twin scrolling style setup, across the manifolds

when you use the balance pipe, it does as the name implies, balances the exhaust gas across the manifolds

but that probably gives a drawback and takes away the splilt pulse style setup

i think i had a similar problem with my gtr, tho i didnt really care too much for it.. i can make the car do it for pretty much the length of the m5 motorway.

it often sounds like a chu chu train just when coming on boost slowly, does not really happen with wot. or notice it then anyway.

angus smart that is the one lol.

especially on the freeway, it does it all the time, unless you give it enough throttle for it to take all the air, then you spool up instead, and let off to slow down and then resume chu-chu, chu-chu-ing.

wouldnt be so bad if it was just quieter

up hills on light throttle was murder

wonder if turbo shuffle affects the R35? haven't read any comments suggesting so yet...

I doubt it, as the turbo systems are completely separate, for the same reason the z32's dont seem to have the problem. I wonder if the shuffle is the turbo's causing each other to go into surge, and building up a pressure harmonic between the two?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
