On the other hand the N1 oil pump costs an extra 3 arms & 4 legs, lol........and with the overhead oiling issues that RB's are renown for, why would you want to exacerbate the problem.

you'll only ever want an n1 oil pump for a race car. its not suitable for street at all, as it cavitates at low revs, unlike the stock oil pump. theyre both as good as each other, just theyre geared for different applications.... at least thats my limited understanding of them...

-D

yeah at the end of the day you don't really need either pump but for the same reason you're going for a better Belt (ie. few $$ more) you are better off with the N1 waterpump.

Maybe your mechanics are not very familiar with RB engines?

EDIT:

Gates or Nismo are in the same league.....both have kevlar in them. Also, waterpumps will give up the ghost under normal circumstances way before oil pumps.

spot on pete!

When i first got my GTR i wanted to "test" a lot of the workshops around the place to see what ones i'd look at taking my car to and to get a ruff gauge on prices. So i sent out an email that included this:

I would like to do a full 100,000km service to it including:

Timing belt, spark plugs, water pump, oil pump, oil, oil

filter, fuel filter, flush and replace coolant, all other

fluids (clutch, diff, gear box, power steering, HICAS,

ATESSA, etc), front engine seals, idle bearing, tensioner

bearing, tensioner pulley studs, thermostat, all other belts

and anything else you can suggest.

and off his own back Shaun from Boostworx recomends the N1 oil pump as well as Mark Patterson (some of you may know him). The reason being is that the R32s have the biggest oil issues and the N1 pump plus a slight mod to the sump when changing the pump is recomended especially for R32 GTRs. Lots of other workshops said either "bring it in and we'll have a look" or "noooo oil pump is impossible to change without $1000 labour and its a head f**k just leave it". So it looks like something i might need to investigate further after your reactions, but... Shaun from Boostworx own recomendation, it's hard to go past that! maybe i should have a better chat with him about it. So if anyone has information re these pumps, link me up pls =)

Interestingly enough, both said for the water pump that the stock unit is fine, its just water, not like its anything that critical like oil! (note, i'll still get the N1 pump from you SLED)

btw SLED, Shaun also recomends the Gates Racing timing belts =P

And finaly some info that people might find interesting: out of the 8 or 9 companies i sent the above service request to, boostworx was a) the fastest to respond b) the most detailed/itemised quote c) the cheapest e) the nearest match to my "demands" f) offered more advice than any other responce and most importantly g) DIDNT ASK ME TO COME IN!!! so i'm always going to take my car there for service etc. and if anyones looking for a mechanic they are my recomendation :P (but i think we all know that already)

Fish,

Whats the modification to the sump they are refering to..If your going to upgrade oil pump you should do the crank collar as well if it's not done already!

I think the big thing with all RB oil "issues" is you need sump baffle them, put oil restrictor in the head and a good catch can system that drains back to the sump...

Getting ready for autosalon takes ages.

anyone know where i can get cheap carpet for flooring?

tell me about it :P car goes in for front bar fit and paint on saturday after the side skirts get fitted, ill be painting interior on sunday and hopefully squeezing time in somewhere to detail it

See if Clarke Rubber has the thin rubber flooring with the carpet material on top?

As a guess :P

+1 to Boostworx. Shaun also told me that it's very pricey to get the oil pump replaced (have to take off the cross-member, etc) so the labour costs would be around $600+ but the pump itself is like $600 but he also mentioned that it's worth the effort.

The last thing you want is low - 0 oil pressure! I might consider getting mine replaced, too. If anyone ends up doing a group buy for a N1 oil pump, put me down for that as well... otherwise in about a month or 2 I'll just get it replaced.

But the exhaust comes first

Hey Sinful, long time =P

i cant remember what was said exactally as it was over a year ago all this took place, but thanks for the tips, i'll make sure i add them to "the list" =D

Yeah its been awhile!! I will be town next weekend..Coming Go Karting??

Check this thread out, it's a good read http://www.skylinesaustralia.com/forums/Fa...;hl=N1+oil+pump

Your standard oil pump is rated up to around 330kws and N1 up to around 370kws. I still run my standard pump (has funky jap internals) and it's in great nick and I wouldnt have a clue how longs its been on there for, so you might not need to replace until you have had it out, but doing the crank collar is a very good idea!

    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
