stock RB26 oil pump choice today

[bigboss59400]

Hello,

I know they are a lot of informations about rb oil pump but I still can't decided ...

I don't want to put an external pump or oil restrictor or extended sump.

Car will stay stock and might see some track days.

 

Here's the option I see so far:

- Tomei pump because it has a 25% increase flow rate only (Nitto is 40% and too much for my setup I guess), if using Tomei should I overfill a bit the sump ? I'm afraid of empty this one)

Tomei manual say you should run it with extended sump...

- N1/Nismo; I'm afraid of buying a bad batch of around 2010. 10 years later is the manufacturing ok with these parts ?

- stock, N1, Nismo housing with aftermarket gears (Reimax for instance)

 

I'm looking for the more reliable option as I don't want to destroy something or pull out the engine for a wrong choice ...so let's say budget is not a criteria

 

Thanks for your advice

You answered your own question there I feel.

If you want a stock street car without any track days then use a stock/Nismo/N1 pump and keep off the limiter.

If you want to do track days go Tomei and Extended sump there is a reason it says to use one.

I have run a tomei and sump with baffles for over 6 years and 40,000km+...so far touch wood no issues.

Thanks

Thanks for your reply,

Then remaining choice are :

- new stock housing with reimax gears (or is there any other brands ?)

- nismo, I suppose the flow rate is increased, can I still use it on a standard GTR ? (without oil restrictor for instance)

re they ok now ? because 10 years ago there were a bad batch...

Tomei all the way(Not saying other brands are bad).

Spool gears, just make sure it's the latest version. The older generation were anodised black (not sure why, because it strips straight away).

I will not go with Tomei as it required more modifications

THanks for the hint Dose pipe

Anyone knows the Nismo flow rate and if it's required an oil restrictor on a standard RB26 ?

Best regards

I'm pretty sure Nismo/N1/stock are all the same flow rate.

[bigboss59400]

So I found 

n1 has a higher pressure but same flow rate

nismo is similar to hks 

so I will go with stock one with Reimax or spool 

thanks for the help

I'm selling a brand new Nismo oil pump if you decide to go down that route.
