well in case anyone is wondering what happened at jambo apart from my converter in the gearbox shitting itself. my n1 oil pump decided to colapse and melt the bearings onto the conrods f**ked my engine.

piece of shit cost me about 10g damage.. aparently their a major problem and little word of advise dont buy one if your running big power.

apparently the jun or cusco ones are around 2g but they the best but apparently so are the n1 pumps ....yea right......

ahhh thats why you were your nice happy self ........................................ NOT

ya rude bastard... well now i know.. sorry to hear that mate, was waiting to see it on track too..

Nothing wrong with N1 pumps

Its the purpose and the treatment that kills them.

Not always,

mine let go on me a few weeks ago, and i hadnt given her a thrash for at least a week.

got myself a stage 2 HKS pump. apparantly these are made to withstand +900HP engines. Not cheap though, cost me $1200 with labour

N1 not too good with big power.....................

If you were building a 900HP engine, you would surely do your research and opt for a JUN or Trust equivilent pump in the first place.

Like R31 Nismoid said, its funny how people just blame the N1 pump when in many cases people havent properly researched their oil pump requirements properly and just fitted an N1 pump to a car that may require something with more flow capacity/higher strength.

well i did research and after asking people what was the best everone said n1 apparently not i didnt care how much it cost thats just what was recomended to me so i took peoples advise...

Who told you the N1 was 'the best' - And more to the point, best for what exactly?

Sorry to hear about your engine :pirate:

Hmm, i was thinking of buying a N1 oil and water pump for my 32 but purely for preventative maintence purposes, but now i'm questioning that, should I?. I'm only running a few mods at the moment, about 130-140rwkw and i'm aiming for 200 down the track. Seems a logical selection for my type of applicaton, no? But a few questions; Do N1 pumps bolt straight on to a RB20DET? What's the price difference between N1 and genuine stock parts For the RB?

i spoke to them at high octaine in sydney they recomended them as well as a few othe r people building big hp cars but i guess i no now,,,,,

have to get another set of crower conrods if anyone nows who can do a good price..

An N1 pump will be more than ample for your application.

sorry to hear that campbell. I know of a few cases now of failed N1 oil pump causing engine failure. It's enough to convince me not to use one in a future build. A friend of mine had one let go just recently after getting his car back on the road. the pump gear just broke. It seems they may have had some quality control problems with them? Jun pump is good value at around $1100 or so.

Once again depending on who you talk to. From what I have been told the N1 pumps are slightly more suited to higher rpm applications. In which case the stock item is the way to go. But hey, just what I have been told. I havent got the equipment to do my own independent tests.

okay n1 oil pumps are okay i guess...street driving.. i def would not recommend an n1 oil pump on the circuit

i would tend to go for a jun or tomei oil pump it really depends what u are going to use the car for and how much power your pushing....

has anyone taken apart an n1 oil pump and standard oil pump to see what the differences are...?

oh great.. i have my newly built motor sitting on a stand in the garage with an n1 pump on the front ready to put back in the car..

really didnt need to read this thread :)

Its always the way, its not a very convincing thread if you have a N1 pump.

I run 440 rwhp and have a N1 pump, have been running it for about two years no probs yet, and i hope not in the future fingers crossed.

Blown motor i feel for you it hurts.

exactly

Dont automatically presume that because everyone uses the N1 pump that its the suited pump for your application.

Everything in life has its limitations,

Figure out exactly what your aiming for, then fit what is suited.

When you say "N1 pumps are no good for big power" how much power are we talking exactly before shit goes pearshaped?

it really depends what u use the car for ---track 300rwkw i killed 2 n1 oil pumps....pieces of shit... i have a tomei oil pump and i wouldnt use anything else... and i also have more power...

everyday driving n1 is fine but if u have big power 330-360rwkw + i would recommend to change it even for street.

    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?
    • Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it  
    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
