hello >_<

imported a 91 gtr a few months ago and its great no dramas at all with it.

replaced all the essintials, filters and oil ect

my question is, after reading alot of threads ect, if i should change oil pump?

since sarly R32's have an oil pump drive that is about half the width of the later gtrs

i looked around and i think a N1 oil pump is best option since car is stock and have no plans to mod it, does engine have to come out to replace oil pump ??

car has only 143xxxkms and motul 300v oil

thanks for any input

Given the stated kms I wouldnt be spending too much money on the motor.

Just be aware the oil pump drive in the car is not as strong as a later model. So I wouldnt go doing a heap of 8000rpm clutch dump starts or bashing the rev limiter continuously.

Have a good look at the harmonic balancer - make sure it is one piece. A failure there will result in an oil pump failure. It will be 20 years old so the rubber in them will have seen better days.

In anycase treat it like it is - a 20 year old motor.

do it with the engine in b4 its too late. its not too hard. i strongly advise u get a stronger pump than the n1 with the short oil drive tho. go nitto or some billet gears.

To do that is both engine and crankshaft out. Might as well do it when it has a planned or unplanned complete rebuild.

In my opinion, the crank collar itself (the tolerances between it and the short oil drive on the crankshaft) and how the collar is applied is more important than the pump itself.

If you are going to do an engine out, you may as well get a R33 crankshaft for the long oil drive.

thanks for all your input guys. might let it sit for now all my gauges are reading normal but every time i drive it its at the back my mind lol

next major service 150k km ill sus to see if this pump swap can be done at home, i really dont want to take engine out :down:

    • Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure
    • Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.
    • Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15  
    • Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.
    • 8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
