New Oil Pump. 32 Gtr

[shaunpierre]

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

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.

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.

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.

Did you install the crank collar engine in? Any risk of engine on head (of installer)? Edited May 24, 2011 by WHITE gtt
