^^^ Dan, are you aware that N1 water pumps are only good for pure track cars? 5 minutes idling at the traffic lights in hot weather will pretty much cook your motor with an N1 water pump - as they are made for constant high revs and the anti-cavitation design of them causes very poor water circulation at low (idle) revs. Just a thought.

Hey andrew

I did some research after last time u told me this, and its the N1 Oil Pump that does this

the n1 water pump has no problems whatsoever, it actually eliminates low end cavitation without compromising top end

besides 5 minutes of idling in hot weather will not be caused solely by the water pump. the tubes, water pressure and rad core is also an issue..

srs, check it out, its the oil pumps. thats why im gonna stick with my stock oil pump, but the n1 is a worth upgrade

-D

EDIT - it may very well be a case also of supporting mods - i have new hose and 52mm radiator. that would help offset idle temps, however I really dont think a 52mm radiator does much more than a stocker when one is standing still ;P

ah, well that is a bit bizarre. That information was given to me by Craig at Main North Nissan, who knows his Skylines inside and out, backwards and forwards. I was going to put an N1 pump in mine when I replaced it and he advised me very strongly against it and told me the story I repeated. He talked me out of spending extra $$ on the N1 pump, so it was actually against Nissan's interest to tell me that.

Weird.

But let me guarantee you - when your water pump is not working properly (like mine wasn't) then you easily cook your car and hit 100 degrees in 5 minutes flat in hot weather .... I can assure you that as fact. Despite me having an aftermarket radiator, oil cooler and twin thermos it STILL cooked, as the water pump was transporting very little water around the engine. It is a heat transfer system, so if the pump is not pumping enough water around, you cook. Easy as that.

The design of the N1 pumps is much more hollowed out on the outer housing which stops the top end cavitation. This does however result in much lower flow during lower engine revs/revolutions of the water pump/belts. Think about the logic.

I am just repeating what I was told by Nissan's top parts guy in Aus :) He sells a LOT of Skyline parts to a LOT of punters, and businesses alike.

Hey Chad, next 35+ degree day go warm up your car then let it sit out in the sun and idle for 10 minutes. I bet you your water temp reaches and exceeds 100 degrees C! Might be good to test out the theory and graph the temps. But hey, if yours works fine then maybe I am wrong.

IIRC the stock water pump is the same price as the N1? Loads of other people running N1's on their dailies... SLED's old beast had one I'm pretty sure (since pete organized the group buy in the first place)...

anyone else?

Sorry for OT.

-D

Edit - Main North Nissan eh? I rang them up to ask about HICAS repair or Consult codes and the guy on the phone had NFI what I was talking about :|

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
