hehe, ben, wasn't saying you were being cheap matey :( just thought that maybe since you were doing it at night you didn't have enough.

Mine was installed when the tank was full. I didn't have to even put my hands in the fuel. Spent a bit over 1 hour to install it, no noise, no nothing. good flow. perfect.

I wouldn't stress too much about the orientation of the sock mate. My car, and others that I have installed, as well as many others that are running gtr pumps on the forums are alright.

This orientation fits the best with that bottom plate still in place. I'm not sure if this affects it, but my pump still has the bototm plate in place, and it is sitting on the gtst rubber ontop of this plate. i'm sure that would help hold the pump steady more. Maybe the orientation that I have it clears the tank.

It seems like you're spending a fair amount of time doing this. If you want, I can put you through to an honest workshop near our area that do an absolutely great job.

I know - northern beaches performance? Thats the place you were mentioning before?

Wouldnt you have trouble when you get low on fuel as the orientation ensures you pick up from the very bottom. That why you can run the tank very low before you have any fuel pickup issues.

Haven't spent too much time. Main wait was the tank seal. Just driving the car now with a noisy pump :D

I'd rather play around with it myself then I know what is done.

Hopefully the pump is ok and I can quieten it down.

Cheers..

How did you go with the pump, were you able to quieten it down?

I have a 32GTR pump in my 33 (there when bought it) and mine is also very noisy. I had no luck repositioning it in the tank, and still makes a lot of noise.

Can someone tell me, what would happen should the pump fail? Will the engine just stall, or is it possible to do more damage, ie. if on boost at the time, will it destroy the bottom end?

Well I just tested the pump for a couple of seconds without fuel. It sounds really quiet out of the car. (At first I had the hose connected and metal pipe connected - it was noisy then).

So I think it must be the way it is sitting in there.

My new pump GTR has about a 2mm thick rubber sleeve aroud it so I think Iwill leave that on and see if I can position it better. Anyone else got tips on which way to bend the bracket etc. Very fiddly job.

It is really tight in there. There seems hardly enough room to have any gap the whole way round the pump and the relief valve piece at the top. It seems inevitable that it will touch the tank. I'm thinking this might be the reason so many people complain of noisy pumps. WOnder if the sedan fuel tank is different

I see somebody mentioned they bent the cradle to the right to allow it to clear - was that when looking from above?

I did this and added a bit of rubber to test. It is a lot quieter but every now and then it makes some wierd noises. Maybe it doesn't touch all the time but every now and then part of the pump rests on the tank.

Will I dont think its moving but it does get a little louder when the car is warmed up and in traffic.

Anyone know if they bend the bracket to the right?

Also, how loud is yours? Mine is like a buzzing - it doesnt get noisier when I rev it though (compared to idle).

Maybe I'm being fussy though.

Should it be almost silent?

      Fark what are the changes of that snapping like that, clean. Nek minnit, custom radiator goes in, with built in oil cooler like those discontinued PWR ones from yesterdeacades ago

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      By Duncan · Posted

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
