I am doing a timing belt on an r32 gtst next weekend and have a few questions.

1. The Crank pulley bolt is 30mm?

2. The torque setting for the crank pulley bolt is 142nm then 152nm?

3. Does the crank pulley have threaded holes for a harmonic balancer puller or do you need a puller that pulls externally on the crank pulley?

4. Does the radiator need to be removed?

rb25 crank bolt head is 27 mm rb 26 is 30 mm , it has from memory 6 mm bolt holes , u have to take radiator out put car in gear handbrake up then u can undo the crank pulley bolt , turn it a few turns ( 10 mm out ) put the gear puller in place once it becomes loose take the big bolt out and the pulley will come out then .

do it up the same way torque it to 142 - 152 nm but dont worry u wont break it in a hurry .

thats true but dont expect do place the bar on the rail the starter wont have the grunt to undo it , u have to have the bar a fair way from the rail to get a bit of movement firts in order to get it undone .

i undo them with a 3/4 inch rattle gun but not everyone has these .

Surely having the car in gear and hand brake on with my 22" snap on breaker bar and a pole on the end will be enough to undo the crank bolt.
Puts too much stress on the gearbox.
the breaker bar has a lifetime warranty doesn't it? lol .
Of course. Once it breaks, its lifetime has ended.

It's like a "concrete warranty" - once it's off my concrete, what warranty?

The gearbox can take over 700Nm of torque. If you can apply that much torque through a breaker bar, you should probably be in some sort of record book :D

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
