^^^ 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.

-adjustable caster rods

-coilpacks

...and a partridge in a pear tree

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 :|

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
