Should I Change Oil Pump On Gtr32?

[JImports]

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,

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

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

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. Rb26detts are prone to oil pump failures. Which in turn say good bye to your bottom end.

If you can afford it definatly upgrade it.

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

thanks for all your help guys

so leave standard oil pump but should get a greddy sump?

Also martini 0w40 is ok?

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.

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?
