N1 Addons

Do the GTR N1 water and oil pumps directly replace the standard ones on an RB26 motor?. Sorry if its been posted before but I did a few searches and found nothing...

How hard are they to replace? I am planning on doing the cam gears and belt and think I read somewhere that its a good idea to do the water pump at the same time. I want to do the oil pump too though....better not be an engine out job. Any tutorials around on SAU??

Also can the water and oil pumps be had for any cheaper than $380 and $530 respectively? I found those prices online.

cheers

Anyone?

Yes, No?

Those prices are about right, I dont think youre going to find them much cheaper.

They do bolt straight on however, the N1 water pump isnt reccomended for daily driven cars as the flow less at low rpm than the standard one to avoid cavitation at consistent high-rpm. So if youre stuck in a traffic jam, the N1 will be pumping less water than the standard RB26 one.

Ah, good to know, thanks.

What about the oil pump, is it a worth upgrade?

[Amaru]

N1 oil pump is fine for daily driven cars and yes I would consider it a worthy upgrade.

Still a point of confusion as to the difference over the normal oil pump, some say it just has a higher relief spring pressure and someone else has actually had two apart side by side and said there is noticeable internal difference in them.

Either way theyre not much more than a standard pump and push a bit more oil pressure than your standard one, so definately not a bad thing.

pffft, for an everyday car it seems better to just leave them standard then!
