dontfeelcold Posted October 10, 2006 Share Posted October 10, 2006 I read on a website that NSX's can have a tendancy to smash (literally) oil pumps, when they expand, the clearances become to tight and BANG! Maybe something similar with the N1's? Link to comment https://www.sau.com.au/forums/topic/136134-n1-oil-pump-killed-my-engine/page/5/#findComment-2572025 Share on other sites More sharing options...
indeedy man Posted September 18, 2007 Share Posted September 18, 2007 So does that $1200 price estimate for a JUN/Tomei/Trust oil pump fitted include an enlarged sump, external oil return, head restrictor and baffles. Or are those extras costs? if so can sum1 give me an estimate for that too. is there a cost difference or preference between the brands? cheers thanks for the info Link to comment https://www.sau.com.au/forums/topic/136134-n1-oil-pump-killed-my-engine/page/5/#findComment-3357320 Share on other sites More sharing options...
Yawn Posted September 18, 2007 Share Posted September 18, 2007 It definitely does not include all of those other oil control mods you mentioned. It is only the price for the pump itself Link to comment https://www.sau.com.au/forums/topic/136134-n1-oil-pump-killed-my-engine/page/5/#findComment-3357558 Share on other sites More sharing options...

indeedy man Posted September 18, 2007 Share Posted September 18, 2007 yeh i thought that was too good to be true hahaha. You are right that i dont need it definitely not now anyway. even for what i would want to do to my car in the future i probably wouldnt require that serious a oil setup. but for 1200 big ones i thought it might be worth it.

NickR33 Posted September 19, 2007 Share Posted September 19, 2007 I've got new N1 pumps for my 25 build... not worried as its really a circuit motor that won't be pushing much more than 250rwkw... almost standard rev limit and baffled/circuit sump, restricted feeds etc what I want to know is should I run the crank collar or not... I suppose logic would suggest with the price of the collar its cheap insurance? also guys that have had the pump fail are you sure you it wasn't detonation that pounded the crank which may have cracked the pump? might be a case of which came first the chicken or the egg? most had forged pistons which can take a fair bit of detonation before they are damaged... of course I would expect some pretty smooshed bearings in this case as well...

GTRgeoff Posted September 19, 2007 Share Posted September 19, 2007 Nick, get the collar mate. Peace of mind, and take a look at the old pump when it comes off to see where the pressure is exerted.

NickR33 Posted September 19, 2007 Share Posted September 19, 2007 will do cheers Geoff... I must admit I haven't looked closely at the old pump even tho its been sitting on the garage floor for weeks! I'm just replacing everything that goes up and down or round and round regardless of condition... and its all pretty stuffed hehe Link to comment https://www.sau.com.au/forums/topic/136134-n1-oil-pump-killed-my-engine/page/5/#findComment-3359982 Share on other sites More sharing options...

R34NRG Posted May 16, 2008 Share Posted May 16, 2008 (edited) f*k me i just read through the 1st page......i decided to go with the n1 pump and the collar thinking that it would suit wat i wanted. pretty much a weekend car now, occasionally the spirted run. very rarely will see anywhere near the redline. and maybe take it to the strip when saturns moons perfectly align every now and then. should i be worried with 350-400kw and a n1 pump? i just couldnt justify spending 2-3k on a oil pump, but if its going to cost me my engine......maybe i should have..........

Don't ask for advice if you are: 1. too foolish to have worked it out beforehand, and 2. a weekend warrior who is going to bash the advice of an engineer that has worked in the V8SC pits. What would you like? Shall we get a roster together of people who are going to come hold you hand? It's not the mediocre power figure that is critical. It's banging it hard on the limiter. Even the most incompetent drivers will soon learn not to. The only other option aside for staying off the limiter is lift the redline to where you can't hit the limiter. Common enough practice if you are aware that it isn't there for every day. For Sandown I used to run an extra 500rpm so I didn't have to shift up between turns 1 and 2, but I didn't then use it for the rest of the track and it was locked down again as soon as the day was over. Now, it's the weekend, so either get back in the playpen son or go do some of that traffic light drags you must be aching for.

I was so undecided as to wether to spend the extra tin on a better pump but the more research i did made me do it and quite a few oil mods at the same time. I ended up using the Jun pump and collar and darn glad i did.

Duncan Posted May 17, 2008 Share Posted May 17, 2008 well I don't beleive that you need anything other than an n1 pump unless you are really going to be abusing it (eg rev limiter launches etc). for your average rebuild an n1 pump is fine. that pump posted above clearly shows huge abuse. You can't really complain if the pump cracks when you are doing that to it. Lucky the pump died before the rod jumped out of the block. We run n1 pumps in the race and targa cars and have never had a problem. Probably used 10 of them over the years. this inclues many race launches (not from redline though) Link to comment https://www.sau.com.au/forums/topic/136134-n1-oil-pump-killed-my-engine/page/5/#findComment-3874127 Share on other sites More sharing options...
Duncan Posted May 17, 2008 Share Posted May 17, 2008 btw yes you might hit the limiter if you are not paying enough attention to your driving - its when you keep it there you have a problem. the drivers foot is what controlls the revs not the limiter in the computer.
