N1 Oil Pump - Epic Fail

[Jack88]

they are a saw tooth gear design...not a gerotor like other RB pumps. Saw tooth pumps are less prone to breaking due to harmonic vibration.

Well im glad i stuck a new RB30 pump on my 2530

Furthermore everyone should dry sump without question regardless of their needs or requirement as risk is not good.

problem with a dry sump setup is cost - for something decent you are looking at up to 7k

i think there was a implied in nismoids post. You failed at the interwebs.

Ofcourse every oil pump is a risk. But we dont log on here to see every couple of months a comment about how my std oil pump just killed my motor, or my (insert brand name here) pump just shat itself...its always the N1 pumps that come up either on here, or in conversation/passing comment or someone at the track blows one up.

Its obvious the risk is higher using one, its virtually the point of this thread. Hearing one bad story should be enough. It was for me, except ive been exposed to multiple, whether on here or at the track. Im sure alot of people who have seen this thread will agree with myself and the others who share the same opinion about N1 pumps.

Its simple. You get whatever puts your mind at ease and fits in with your budget.

Dry sumps all round for everybody.....hooray

guys loosing sleep over the pumps go and buy the reinik (edit reimax... still getting used to name change) gears. they are very highly regarded in japan and folks smarter than me have been using them in aus with great success. they may not be jumping up and down telling everyone about it, but the price is right, they have the research behind them to back up their product and that should be the end of your oil pump problems.

If you're spending 7k on a dry sump setup you're spending too much.

nitto would be my choice, crd has been exposed to all oil pumps available and i trust the opinion of a man who started modifying gtr's when we were all still playing with matchbox cars and smashing them with hammers to simulate an accident

dry sump for me is overkill for a weekend warrior

Where are these available from?

I still think the best fix would be a splined collar/gear.

[Moodles2]

Do the Reimax gears replace the gears on the N1 pump or the stock pump?

Cheapest Reimax gear set i can find so far is 670 au + del. through Greenline.

It probably is best value for $$$ if you are planning on taking your engine to pieces or in the build stage.

Lookin forward to these new gears!

would they work on a stock pump? or does the stock pump not provide enough pressure?

say compared to a n1?

They can be made to suit a stock pump, but these first ones are going to be for the N1 pump.

Pump selection should be left upto the engine builder.

I to had a n1 let go on e and decided to go external pump

i have had no probles since and thrash it of limeter all day at the track and the cost was not to bad

$1000 for peterson single stage pump

$200 for mandrel for the crank

$200 for speedflow fittings

and 1 day in the gargae making a bracket for the pump

This is the way to go imo

That's under valuing it a bit to say the least. Add another $600 and ur closer to the mark you woulda spent. (not saying u didnt spend that but just adding this so everyone doesn't jump to the conclusion it only costs $1400 to do a complete external oil pump setup)

Shane, are there different thickness N1 gears? I remember getting confused when I last looked at the Reimax ones

There are indeed my good friend. So what we'll have to do is the person after a set will have to specify what thickness gears they are after.

Cool, I'll try get my oil pump off this weekend and confirm thickness.

FWIW, here are some parts numbers that I came up with and pricing for an external oil pump kit. I only really needed to find someone to make a bracket for the pump itself, most of the parts are there minus the hosing and belt. Might be a couple of extra fittings required depending on where / how you wanted to mount it.

Some of the prices may have changed since I did it (about 4 months ago)

[Moodles2]

Were the Group A GTRs from the early 90's a dry sump or externally oiled?

JWAuto are doing CNC brackets...their work is incredible...the same CNC machinist 888 Racing use. Top shelf stuff. They are doing the brackets in a kit only though...im doing a group buy on them as soon as they are ready. I saw one of their VL CNC'd rocker covers to suit single cam engines running roller rockers...porno! Ill see if i can get a pic.
