N1 Oil Pump - Epic Fail

[FineLine]

If i was over reading the play i'd be saying that you said Tomei pumps are shit and you shouldn't buy them, being you've also kill one

They are not shit, there is only select evidence here and there, perhaps as paul said the material has changed, who knows what goes on in a manufacturing plant during tougher times.

Dude I dont know where you get your info But i reccomend you find a new source. The current one is making you look like an asshat.

The only oil pump I have ever purchased and or owned other than the original stocker is a Jun. This pump has survived 2 engine failures. One when the clutch ripped the engine and drivetrain apart and the other when I shat a turbo through the engine.

The oil pump has been apart and inspected and crack tested on both occasions and is now happily singing away on track duty at over 500 rwhp.

that post did 2 things...made me lol and then gave me a warm fuzzy feeling that my JUN pump may live longer than i expect it too. Nice one Fox.

Well i just went by your post

Check out the price of the Jun pump while you're at it. A fair bit less than the tomei item and I have broken about everything except the Jun oil pump to date.

Can be read in many ways

Just keeping it real Paul. I have the utmost respect for most things Jun. That oil pump and a set of Jun pistons were among the few survivors of that clutch debacle.

I would gladly reuse those slugs if i could find a tight enough block. They are standard bore and its tuff to find a block that will give us the correct piston to wall clearance.

Subsequent research led to Cosworth being the actual manufacturer of said pistons. Speaks plenty for Jun that they chose such a well respected outfit to outsource from.

Ash returns serve very close to the baseline but manages to keep the ball in play

Point taken, I was referring to engine components in general. As for the Jun pump it is one of the few survivors.

hehe... the fact im working graveyards isn't helping... im seeing shit i probably wouldn't normally

Ah i see, that is indeed good news then! Least it's clear for everyone (if anyone has been silly enough to be awake for nearly 24hrs like me)

Thanks for the clarification dirtman

Good ole debates on oil pumps, always entertaining

[FineLine]

And as for you dirt man, Get your stick out of our pot. Go brew up your own concoction to stir.

[NickR33]

yeah I read that the same as Ash... but I have no excuse hehe

I've had N1 pumps on a couple of engines that I've destroyed, pump was never at fault though... that said recently I've found myself short shifting at 8K to be careful I don't nudge the limiter

anyway that's hard luck Rezlo, sounds like its a killer setup, would be a wild ride... I would be checking that bottom end really carefully, fingers crossed for you

some people pay good money to see sh1t that ain't there and stay awake for days...lol...you however are making money from doing it so don't be a sook.

my advice is buy some reimax gears for the pump you have. should be cheaper than any of the other options listed and they are good. very good. they have the runs on the board as far as I'm concerned..

I hear a rumor you were going to be at the bank tomorrow night.... Not true??

Have a chat to Powertune in NSW about their RB26 oil pump gear sets. Made out of somethin crazy like P20 tool steel or somethin and the same size as a JUN gear set and they can machine the stock housing to suit.

I like this idea.

I had an N1 pump fail <2000km old

Had new gears machine, apparently by Powertune - fingers crossed

[R32 Driver]

I called Powertune and they dont know about/sell these gears?

who did you speak to? and rough cost?

Thanks

Brisbane VL guru's JW Auto are producing an external kit we are helping them design. After problems getting the last supplier to move on these JW is keen to produce a bolt on kit for us. These kits will unfortunately for some require the removal of air-con but will utilise a modified STD pump housing making them a truely 'bolt on' kit. Very easy for someone with basic mechanical skills to install and will come with ATI balancer, modified pump housing, Peterson single stage pump, CNC'd adjustable pump bracket, Gilmer drive pulley's, anodised fittings and braided lines. They wont be cheap but they will be the best 'wet' sump set-up for RB's.

Once JW provide a sample kit for us we will make them available for limited release via a group buy.

listen to paul (dirtgarage) - i spoke to my tuner about this exact subject & it was simply explained it to me like this:

"the n1 pump has a sintered steel gear which is more likely to shatter under load whereas the nitto pump has a billet gear which literally has chewed up bits of a cast iron block in a recent engine failure"...need i say anymore

[Marko R1]

oh & the nitto pump is very well priced when compared to the tomei/jun

Speak to Dan at ERD (SAU user elite32) - he is manufacturing the same gears now
