Oil Pump

[94 skyline]

Hay

I just had a dyno done to me car it is putting 183rwks i was advised by someone that i should upgrade the oil pump, he reckons that that kind of power i should upgrade i want to put a boost T on aswell to push it to 200rwks, is this true about the oil pump

cheers

I highly doubt you need an upgraded oil pump for 200rwks... I'm pushing around 260rwkw with standard oil pump without any oil control issues for about 10months now.

I have done my water pump though due to '100,000km service'.

I'm only pushing 170RWKW's in my RB20 and I just did a big end bearing up at wakefield due to oil starvation. In saying that I was bouncing of 7500 rev limiter (maybe not bouncing but it was a drift day) and had the car being thrown around fairly violently.

So unless you are belting your car side to side, and redlining it, you don't have much to worry about, But i would do it if you were building your motor

Yes - on the proviso you have done the rest of the mods.

183 rwkw in a GTS-t is very good so I suspect you have a few mods already. FMIC, Zorst, Turbs, Puter etc....If you want to push 200rwkws - safe not sorry. Spend now and save later. Would you risk an engine rebuild?

Im probably going to upgrade my oil pump i would rather spend money on that than an engine rebuild,

Thanks

I don't know how much over 200rwkw your going to go, but do you think upgrading your Oilpump is the only thing you need to keep up that power level?

It is a bit of work to change the oilpump.

well i want more power so will will be doing more mods to my car,i have got someone who can fit my oil pump for me

[JarrydF]

you should be alright with the stock pump. Just get a oil pressure gauge and make sure the oil pressure is always at a save level.

[BMYHOE]

well you might as well rebuild the rest of the motor while your there....

Talking about what sort of skyline exactly?

[94 skyline]

Its an 94 r33 gtst This is My first nissan skyline so i am not sure on what mods i need to do so it does not blow my engine and to get more power

[StinkyPoo]

i've got a dyno print out for my RB25det with 236rwkw... I'm pretty sure the engine has had no mods, and i've been drifting, hillclimb, motorkhana with this car.

[R33GTRKid]

oil pump I am pretty sure means motor out, so you may as well forge the bottom end given the costs associated with R&R the motor verses the parts to forge. Then you can run a comfortable 300rwkw without stressing at all.

Ok, as its your first skyline ill be very blunt;

-Changing oil pumps in a GTST is a waste of time with that power level, or if its working fine

-You will break the oil pump if you bounce off the redline time and time again

-Always warm up before using more than 30% throttle on cold start

-Always cool down (fit a turbo timer if you're a leadfoot)

-Before adding power, sort out suspension and a short shifter for the gearbox

-Once you've got it sorted suspension wise look for more power

Powerwise;

-FMIC (forum sponsors)

-EBC (forum sponsors)

-HKS GTRS kit (forum sponsors)

-ECU, ideally one that uses MAP vs TPS for mapping (forum sponsors)

-Quality exhaust including highflow cat, good dump pipe (forum sponsors)

EDIT: If you need any further clarification, call a few workshops and get quotes for "just a new oil pump fitted"

thanks for the info guys realy help

[rossco_01]

i have a 33 gtst pushing 230 at the rears and never had anyone telling me i need a new oil pump talk to autotech in hume Ed will sort out any questions you have he knows his shit about skylines and RB motors

Mistake on my earlier post -

Beggining of the thread I assumed 94 GTS-T was an R32 RB20DET not an RB25DET R33.
