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...... |

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. -------------------- Built and Tuned by

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?

An N1 pump will be more than ample for your application. -------------------- Built and Tuned by

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.

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. -------------------- Four Doors For Life!

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...? |

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