I'm not totaly happy with my oil presure so I'm thinking an upgrade to the oil pump may be the go and after a bit of searching I have come across NITTO,and N1 and I'm thinking there may be more.

The NITTO was around $1200/1300 and the Skyline GTR NI $580 appart from the $ how big is the difference between these two.

Will the GTR N1 fit the 98 R34 GT-T and will there be a significant improvement over the OE GTT one in there now ?

I'm not modding this car, I only push it around a little bit occasionaly, I'm not $1300 bucks worth unhappy with the current pressure and it wont see the track while I've got it.

Having said all that summer is coming so soon would be the time to do this if I'm going to so any advice on this would be gratefully received.

Oh and while I think about it how hard / many hours in fitting to a 98 R34 GT-t.

I don't know how R34's work, but incorrect oil pressures (32's, 33's) are the result of a dirty pressure switch, I would first clean the switch (near the oil filter). As for fitting a new pump, its a engine out job. Others have reported the Nitto pumps are as good, if not better than the $2000 jap pumps.

If it's not going to the track, or be bouncing off the limiter, there are better ways to spend your money than getting track orientated pumps for a lazy daily driver.

I definately wouldn't worry about the oil pump. To replace it you will need to take motor out and pull it apart (it is possible on car but still heaps of labour, balancer off, timing belt off, drop subframe, sump off).

You can get a second hand rb25 for less than the cost of an oil pump....

:P Thanks guys didn't realise how much info was in the Epic fail thread thanks for that , oil pressure sender cleaning will be done.

Just a bit more I came across this:-

NISMO OIL FILTER

FEATURES:

  • 21% LESS PRESSURE LOSS
  • 24% INCREASE IN FILTRATION
  • 10% LESS FLOW RESISTANCE
  • 37% INCREASED LIFE

PRICE: $49.95 EACH

And just wondered if there's any mileage with these claims or is it just manufacturers rhetoric ? reason I asked I noticed an overall slight drop when I changed the oil and filter last time the filter that was in was a Jap no name which I think may have come in with the car.

I'm using 10x40 Nulon quick flow full syn and a Nissan OE filter.

All I can say is FARK THAT! I could be wrong, but with the 'shithouse' Ryco filters, I have no strange variations or delays in oil pressure (that said im going to start using Nissan ones for peace of mind)

IMO if you're going to spend $50 on the filter, add that amount to what you spend on oil and use Motul 300v or something.

I think it's all a load of crap, when theyre $8 each, just change it when you change your oil.. May as well use a genuine Nissan filter, theyre pretty much the same price maybe cheaper than the Ryco equiv.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
