Never done it before on a skyline96 gtst

but is the hardest bit the pulley or something else?

just worried the cams may move when i take the belt off( so do i need to hold them in place?)

due to spring preasure?

ive also been quoted under 50$ for a water pump from auto pro but thought water pumps were dear for my car?

i'd be double checking part numbers... that doesn't sound right, mine cost $130 from tweakit (probably not the cheapest but can't be that far off) get a manual if it's ur first time (can buy a CD version on ebay for like $15)

But u just have turn your crank to no.1 TDC then your cams should line up with your 0 degree mark there is one on each cam and i think one on the crank (can't remember)

I got the manaul for free ,that guy who sells them is a scam! i know he got his at the same place :) it on the web for free

There is an excellent thread on the STAGEA forum. Covers all the steps to change the timing belt on a RB26 motor , Yes , the crank pulley nut is the hardest thing to undo , its done up to 650ft/lb torque , you may need to make up a pulley lock tool to hold the pulley still while you crack the nut.

650ft torque do you need a 10 ft extension bar for that or does metal atoms seperate at that force?

are you serious? no torque wrenches will be able to do it up again? i was thinking is it ment to be 165ft pounds?

i don't know what it actually is, but i can tell you it is far,King tight... took me a while to get mine off...

make sure u lock ur flywheel before attempting to undo it..

isn't it hard to actuall 'pull' the harmonic balancer off as well? ie need a proper puller?

yeh, only costs $20 from supercheap can get cheaper but they didn't have small enough bolts to fit factory Harmonic balancer...

water pumps from an rb30 are dirt cheap - be careful they have less blades that a standard one so they pump less water - the rb30 ones are kind of half way between standard and the n1 water pumps.

I thought the balancer bolt was only 450lb/ft but yes still bloody tight :).

Make sure if you buy bolts for the balancer puller that you get high tensile, at least 8.8 and preferably 12. If the bolts snap you are in a world of trouble getting the balancer off.

Make sure you replace tention spring correctly behind pully as it is ecentric. spring must clip in behind dowel to give correct tention on belt. Get onto VACC for instruction manual for rb25det it will help you a great deal. :)

You actually dont need to buy the bolts because the bolts that hold the cam cover on are the correct size. I did this in mine a few months ago however was a rb20 but i would assume the rb25 would be the same.

And I paid $70 for my water pump from repco.

Just buy a new crank bolt from Nissan, the one for my car was only about 10 bucks and you know its going to hold up.

Damn the old bolt was a bitch to get off. 1 metre breaker bar: no good, crank over engine with extention bar under chassis rail: no use. In the end had to use a trucksize rattle gun, which meant radiator and condensor out just to fit the gun down there!

And i went a genuine Holden VL waterpump because it has the no. of blades between std and N1, the car has never overheated. It has a Nissan part number anyway, most likely the same as an R31 RB30E, works perfectly and alot cheaper.

I reccomend taking the radiator out. Makes removing the harmonic balancer alot easier and it will probably save your knuckles from a good skinning.

You can line up a torsion bar so that it's up against one of the rad supports or the ground even, and use the starter motor when cracking the big mofo bolt for the harmonic balancer... some people don't like to do that though..

As someone said, just line of TDC 1, and everything should be fine. Just check the markings about 50 trillion times before you put it all back together.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
