Just wondering what's the deal with all the apparent genuine n1 oil pumps on eBay, there as low as $175au in the states and all say there genuine Nissan and come in packaging and gasket. Is this a Chinese scam or are they real? http://www.ebay.com.au/itm/SKYLINE-N1-OIL-PUMP-JDM-GENUINE-NISSAN-RB25-RB26-/250976280154?pt=Motors_Car_Truck_Parts_Accessories &hash=item3a6f5a1e5a#ht_500wt_689 (http://www.ebay.com.au/itm/SKYLINE-N1-OIL-PUMP-JDM-GENUINE-NISSAN-RB25-RB26-/250976280154?pt=Motors_Car_Truck_Parts_Accessories&hash=item3a6f5a1e5a#ht_500wt_689) http://www.ebay.com.au/itm/Genuine-Nissan-N1-oil-pump-RB20DET-RB25DET-RB26DETT-/220817136311?pt=Motors_Car_Truck_Parts_Accessories &hash=item3369ba1ab7#ht_2585wt_989 (http://www.ebay.com.au/itm/Genuine-Nissan-N1-oil-pump-RB20DET-RB25DET-RB26DETT-/220817136311?pt=Motors_Car_Truck_Parts_Accessories&hash=item3369ba1ab7#ht_2585wt_989)

I doubt that they are genuine N1 items for that price.

Yer I know, that's what I thought but then u can see the Nissan stamp on the housing. I know china do good copies, but hmmm? Any one used em yet or shall I be the guinea pig and see what there like

you can get a genuine RB25 oil pump for around the same money shiped over, fit the crank collar and you have a pretty sweet deal Some original photos have not been recovered yet.

I don't think they're ideal with a 30 because unmodified, they pump too much oil. Someone will need to clear this up, but I think thats the jist of it..

they are being sold by nissan dealers so I'd say more than likely they are genuine parts

I'll give ya a ring on the weekend mate

pigsy might be able to help me with this one. But if you change to a N1, don't you need to change the oil collects Some original photos have not been recovered yet.

You need a crank collar welded on, or grub screwed if you prefer. Either way it requires the removal of the crank im pretty sure. For the same price as the pump, billet gears, crank collar and welding, it would probably make sense just to spend all that money on a wet external (as pigsy already convinced me to do)
