hey i have an r33 s2 gtst and i need a new timing belt on it, i was wondering if the gears have marks on them that you lime up with the belt so that it is installed perfect, i know it needs to be tuned and stuff after the belt is installed but if i can change the belt myself and be able to start and drive the car safely then i can just get the timing tuned. I was just worried that if it didnt have marks so i know the right alignment of the gears that i could damage the engine when i go to start it

The gears do have marks on them, but you line them up with marks on the metal plate behind the gears, not with marks on the belt. Basically you line up each cam gear with it's mark, and set the crank to o degrees, then put the belt on without moving any of them. If you set the crank to 0 degrees on the timing marker before removing anything, the cams will be already lined up (assuming the cam timing is correct to start with).

I would also change the water pump, timing belt tensioner & idler, and the camshaft seals while it's apart.

Also....why would you need a tune after replacing it????  Hell No!!!!  You aren't replacing/renewing anything that affects or changes the tune.
Follow the guide and drive!!!


He wants to adjust cam gear timing...
I honestly though most people didn't do this anymore because of the gains vs dyno cost.

Not accurately enough. You need to use a timing gauge light to get it right.

I could never get my timing light to work correctly on an rb. Mine is the clamp over line type. Not a direct plug.
From memory it was showing off the scale, like 40+ deg

 

I honestly set and forget. I'll take it to my mates shop soon and see if we can get it spot on using measurements and pen marks.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
