using a used jun oil pump

[NismoS-tune]

If you do alot of homework on RB26 builds you will also find that Eagle rods fail actually more often then the N1 pumps if you put it into perspective. And look how many of us run eagle rods ?!

Someone (shop owner) convinced me the Eagle rods would suffice under 800hp and be reliable... Soon after I realized that I could care less that they were half the price of the good rods so I tried going to Carrillo rods but it was too late as everything was already balanced. We'll see how they go. The weakest parts of my car are the rods, transmission, OEM fuel tank and driveshafts. Let's hope it stays together eh?

i am giong to be under 700whp cause i am going to be using my stock tranny so i will be around 650 and hope my tranny holds up.

I wish I could afford to make that kind of power

yes evilgtr all of that is true. and i have done my research believe me. hence why i just revieved my bnib r34 crank. i also ordered pistons and rods. i am giong to be under 700whp cause i am going to be using my stock tranny so i will be around 650 and hope my tranny holds up. i am going to be at the track rather reguraly for 1/4 so i wont be on the limiter all day but will see some limiter. i will be locktiting my screws but as far as reimax gears by the time i do that i might as well spend the few extra hundred and buy a jun.... i still have to think about it more i guess. i know rips uses the n1 on some of their 1000whp gtrs with no complaints. so i guess the hating on the n1 pump might just be alot of heresay.

If you buy a genuine N1 pump and have the gears replaced with the reimax gears then re-seal the pump and and use some locktight on the srews then punch the heads to avoid seperation. Add a quality Crank damper and you should be fine. I am running the N1 pump but didnt opt for the reimax gears - instead I had my gears removed and machined to remove all the tiny burrs then re-assembled. So far so good.

We all know there are alot of horror stories regarding the N1 pump but CobrAA hit the nail on the head when he said people are quick to blame the pump. Everyone drives there car differently,if you intend on eventually running 7-900whp or taking it to the track and excercising the rev limiter on a daily basis then maybe a larger pump is what you need for your application. But if thats the case you will also need stronger rods,crank,mains,valve train ect ect. If you intend on running 700whp or less then I feel the N1 (properly set up and with supporting mods) will suit your application just fine.

The Aussies punished these pumps for years on the track and Iv yet to see video footage of a GTR pulling over or quitting the race due to pump failure,HI OCTANE used the the N1 pumps on all their time attack R32 GTR's.

If you do alot of homework on RB26 builds you will also find that Eagle rods fail actually more often then the N1 pumps if you put it into perspective. And look how many of us run eagle rods ?!

All parts have the potential to fail, the trick is trying to perfectly match parts that will fit the criteria for the intended purpose of your build.

Well if you want to take the risk mate then go ahead. But if budget permits go for a new one. Nismo oil pump is just a bit cheaper compared to JUN, you might want to check it out also.

I'd do it. It's still a Jun pump. New used doesn't mean much if it's in good condition. Kinda like some people buying a car that's already modified. It's used.

Do it

yea i know.... i have just heard so many conflicting arguments on the n1 apparently there was a bad batch of them that made it out there such as the ones on ebay. i am spending about 10000 on my build and i dont want a bad oil pump to ruin it. and evilgtr your right cheaping out always bites you in the ass i just cant fit it in my budget spending 1500 on a oil pump!!!! i want my car done as soon as i can. I know in an ideal world i would wait and save and do it right but i am not that patient and i am not trying to cheap out on something i need. just trying to get some opinions. i might end up going with the n1. of all the bad stories i have heard about them i havent heard any problems when they had a new r34 crank. we will c.......

[cobrAA]

the thing is.... people never tell the whole stories and just blame the n1 pump lol. They're good pump.

[evilgtr]

You didn't order a used crank,rods,pistons for a reason.. So why cheap out now.
The old saying goes "we never have money to do it right,but we always find money to do it twice"

You won't have issues with the N1 pump, ultimately it's your car so the final decision is yours.

So i dont wana get flammed for this even though i might. But what are your guys opinion on using a used jun oil pump? there is a guy on here selling his. I know its a cheap way out and i planned on going with a n1 oil pump (i ordered a r34 crank, weisco pistons, eagle rods....etc) but i have just read far too many horror stories about the n1 pump (felix) for example. so how sketch/bad is it to run a used oil pump? i mean it is a jun i know its not as good as tomei as some have said but it is still supposed to last. so anybody feel free to chime in.
