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...

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.

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
