GTR Owners Read This!!

[GTRman1992]

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 JUN oil sump.

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.

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

[maccattack]

Trouble is, dry sumping will cost you around $5000

yeah thats if you go out & buy a full dry sump kit or you make (if you think you can)

it your self should only cost around $1500 or there abouts

You have no idea how many times I thought I have prepared my car for the track only to be told this this this needs to be changed first. Not a cheap hobby nor car to choose for the track.

What things were you told you needed?

What things were you told you needed?

mainly oil cooler and oil sump but i was very suprised that the GTRs are not capable of handling track work straight from the factory
