  1. I han't done a Neo head.. but I'm guessing that Nissan didn't stray too far from what they already know works.

    Please take another pic, up close and front on, just like mine so everybody can see what your looking at.

    Top work on the mod. Im about to embark on this procees, Where did u get the replacement plug, Did u press it back on or hammer

    Thanks

  2. Gday,

    Just replacing the timing belt on my rb25 headed 3.0, Im using a dayco 94777 belt to suit dual lower tensioners, its a 150 teeth belt.

    I have aligned the cams with the dots & got the crank on the dot also, the first 2 cam lobes are facing outwards & cylinder 1 is up, do I have to count the teeth on the belt to make sure its all aligned or is this all?

    Yep, Align marks, Set tension, turn crank twice, check again job done

  3. ^ I don't know where you get your advice from mate, but it's horribly incorrect.

    Bigger pipe down NOT reduce down low torque. Infact it increases it by allowing the gases/air to move around more freely - so long as the motor is tuned accordinly of course.

    So putting a bigger exhaust on ur car will have the same response as stock,    Not a chance

    So ur saying a bigger pipes air speed velocity at low rpm is the same as a smaller sized pipe.   Not a chance

    The smaller the pipe, the greater the air speed velocity will be, until it gets restrictive, where it robs u of top end

  4. i dont believe there is any response gain by using a split dump

    Whenever u change the size of a pipe,  

    bigger pipe=more flow at top end and reduced flow(air speed) down low.

    smaller pipe= increased flow at low rpm  while being restrictive in the top end.

    3 inch pipe will flow say 500hp.

    Where two 1.5 inch pipes will flow 500hp will alot faster air speed and alot better response

  5. My dump gasket has gone and 4 of the bolts have vibrated off, so I thought Id put a split dump pipe on

    The turbine outlet is quite smaller as it is split,   This will obviously bring boost on faster but sacrificing top end flow

    I believe they split them to stop the pulsing of the gases out of wastegate interrupting the flow of the turbine outlet

    Are they a worthwile upgrade, or only for response and midrange

  6. Does anyone know where the outside part of the inlet VVt cam gear should be when setting the timing at 0 deg?

    The back of the cam gear doesnt have any reference marks, see pic

    You can tell by the impression the bolt has left on your gear, from ur photo looks like the centre
