Hey guys,

I would like to know if it worth changing the oil pump from standard to aftermarket (JUN etc)?

I just bought a R32 in Japan and as a first time GTR32 owner I do not want to blow the engine due to oil stravation....

Any help would be greatly appreciated....

Cheers,

thuy

Its a big job to do for just the oil pump.

Here's some things to do instead

-Always start the car and drive straight away(no sitting idle)

-Never use more than 25% throttle until the oil temp guage has moved above 70degrees

-Always use slow shifts until the oil has warmed up

-Dont use cheap shitty oil

-Always allow for cooldown time

Easy :laugh:

If you plan on taking it on the track, overfill the sump to the bottom of the hump on the dipstick, and try not to use r compound tyres (they generate lots of grip which moves the oil in the sump)

If you blow the motor up for whatever reason, THEN you do the jun oil pump :down:

wow thanks for the great tip

couple of question though?

-how do i know when is 25% throttle?

-does it help if i get a greddy oil sump?

and i think since you know so much about the car I also would like to know the following

- i just bought a Greddy T517z(2) would this fit on the hks dump?

-with the following mods

turbo back exhaust

oil cooler

pfc

is it ok for me to make 250kw@the wheels using standard injectors/pump? and not blow the engine? It will be tune by ben at Racepace

thanks for the helpmate

mate i would suggest putting a bigger oil pump for sure.

If by "bigger" you mean "higher flow" then you will increase the risk of oil starvation, as the higher flow pump will push more oil to the top of the motor than the standard pump. This will empty the sump more quickly, unless you add other oil control mods.

Read SK's oil control thread Here

+1 for N1GTRs tips, re 25% throttle, I think he just means take it easy until its warmed up, ie just drive at normal traffic speed. Also;

- dont hit the rev limiter

- dont use oil that's too thick. IMO ?W-40 is as high as you need to go with a quality oil.

- providing the injectors and pump are in good condition they'll be fine for 250

Only reaspn for pump failure is the gearset cracks in the pump, nothing to do with lack of flow. As previously mentioned more flow is actually worse as the problem is oil control in the RB's. With too much oil being delivered to the head and under high G-forces it just adds to the problem of oil starvation. Check the oil control thread if your serious about building a tough RB. Otherwise leave those bits stock. Its kinda all or nothing in some ways.

I read the oil control thread but don't really understand it. :thumbsup:

As I said I'm not going to even rev over 5500rpm nor take it to track/ hard corner etc....

Just want a reliable good looker car (i bought gtr32 after I sold the chaser manual) have I made a mistake?

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
