GTR Oil Pump

[Genesis®]

Hi Guys,

i got some gears (sump extension kit, 10row cooler & oil filter relocation kit, cam gears) going into my GTR32 and wondering is it possible to modify my existing oil pump for more flow? I am think either modifying or get a new N1 oil pump but would like to hear any past experiences which some of you guys might have.

thanks in advance.

All I know is I've been told to get a new oil pump as the stock on the GTR R32 is far to small. Look's like I'm after a new N1 as well. So be intertested too on the advice.

BTW My beast was fairly well modded when I took delivery but some of the essentials have not been done to support the other mods. It has like a pair of GTR R34 N1 Turbs, all the HKS, TRUST and Apexi bling blings you could want for Christmas.

But no Oil Cooler, larger Oil Pump, Sump, Radiator. But hey - I no complain. Saved me heaps and has given me something to work towards.

I have Nismo Fuel Pump, SARD Injectors and Fuel Reg being installed and tuned today

the problem with the r32 pumps is the drive engagement is too small, nissan knew this and fixed it on the r33 an r34 you should invest in getting your crank collared then fit a newer pump.. You can mod the stock pump by changing the spring rate in the pressure valve, this is all the N1 pump is anyway, something i found out after paying for a r34 N1 pump then having a close inspection and realising the stock one is the same!!!

i have checked with Nissan and seems that i can get a new collar from them. Is this the same crank collar you are referring to?

thanks

I thnk that later model R32's have the same crank as the R33's.

but I'm not sure of the change over date unfortunately

the 94 r32's with the pull type gearbox run the same engine as the r33 they have the re designed crank drive, around may/june i think they changed!

93 model r32's also have the larger crank journal. I just fitted a jun crank collar to my early 32 crank . If i had known earlier i woulda just used a later model crank .

Talk to Ed about this, Greg from Pro Engines did the upgraded spring in the pressure valve on mine which is the only difference on a N1 pump. Its a piece of cake to do when you've got the sump off.

Ive also got Tomei sump baffles sitting at Ed's if youre interested
