Neebo is nothing like the track. it is the longer high speed sweepers that cause the problem. The oil goes to one side of the sump and is held there by the G-Force so the oil pick up only breaths air not oil.

This is why I have only gone to Morgan Park in Warwick for track days so far. The track is more like a closed road than a race track. No prolonged corners or high speed bends etc.

GTRman1992 exactly what I've been told. You can never pull as much Gs on the road as you can on the track. But I'd really wanna be safe, so I popped the sump on to have peace of mind. Not really keen on 10 grand worth of damage.

John...yes I believe you have to pull the engine to get to the sump, not too sure on this though.

hey does anyone have any ideas or pics on what a good baffled or gated sump would look like or bits you have seen that are a good idea to inprove on?

I've got my rb25 in bits and just about to put it back together but would like to put some baffling in it as i will be doing a bit of fast driving even though its not a rb26 or gtr i'm guessing the rb25's suffer from this aswell just not as bad?

BTW aftermaket ones are out (i'm a cheap bastard :( ) and know a lot of people that can help with the fabrication.

Thanks

John

The trust oil sump increases the capacity and the sleeve around the new pickup acts as a baffle.

We put one on the Targa prepped GTR and had absolutely no oil surge issues.

The Jun one is just a baffle plate/windage tray and does not increase the sump capacity which is one of the biggest problems with the R. It is virtually the same as the Nismo one and all it did( yes, we tried that first ) was to delay the onset of the oil guage dropping.

My advice is if you are track running a GTR , have a very good fast reading oil pressure gauge with an adjustable red light.

I used that light to save my engine on a few occasions last year when I won the Enjo Speed Event Series.

Do the things Sydney Kid suggest but don't forget , they only have 4.5L std and with the std *oil up the top*problems, there may be as little as 2L left in the sump to run the bearings.

Cheers

well I would of never though that the R's were like that

another way you guys can fix the prob is running a dry sump set up if your going to be on the track a bit it is not a bad idea a few more dollars in it than $900 but yeah you get the benifit of running a supper cooling oil system & get ride of surge once & for all

      Ceramic turbine damage to engine - what did yours do?

      By Lithium · Posted

      Whoa, that's a name I've not see for a long time! Sorry to hear about the engine / turbo damage.  Fwiw with any engine problems it often really a case of just seeing what happens when it's apart, ymmv - I wouldn't rule out the possibility that the damage isn't even from the turbo failure, or possibly from a combination.  The airflow between cylinders isn't dead even, injectors can go off over time as well, with the turbos overboosting if you didn't have upgraded fuel system there could have possibly been a bit of leaning out - stock triggering is often a bit unreliable by this age too.  Basically its an old engine and a few things could have been going on, and you won't know how much work is needed until the engine is apart.

      I'm just shocked there's a euro driver on our roads who is thinking of other road users and not attempting to blind everyone. I wonder if Prank uses his indicator too...

      So whats the deal with the porous block VR30DDTT

      By Duncan · Posted

      Its hard to tell really. The Q50 owner's forum talks about it a lot and has quite a few people directly affected, but no idea what % of cars sold actually had the block replaced. Also, there seem to be 2 distinct issues which both get diagnosed by Infiniti as requiring a block replacement (no wonder they are going broke) 1. "Porous block" where coolant mixes with oil through thin or poorly cast parts of the block 2. Head coolant gallery plugs not sealing. If I was noticing engine coolant loss I'd start with cooling system pressure test (as always) and then I'd pull the cam covers and reseal the coolant gallery plugs on both side before worrying about a potentially porous block.  If neither of those did the trick it would be put in a second hand engine out of japan; I haven't checked pricing but I'm sure there are plenty around by now as they've been in production 10+ years

      To clarify what I posted above, I thought you both had a situation where it cancelled sooner one way than the other.....if it is reasonably even where it cancels in either direction that is probably normal (consider gentle movements like lane changes, you don't want it to need half a turn of lock to turn the indicators off)

      Son, in this country, that is a piece of Gyprock. f**king drywall. FFS! I also like the autocorrect of trailer to tablet. I was reading it and thing, "what the hell drugs is he on?" Then the photo made it clear enough.
