I have seen oil surge in my R33GTS25t, I have 225/60x16s, DBA slotted rotors with EBC greenstuff. On hard stop from 60-70 kph with a full stop (ABS active) the oil light will flash for less than a second as the car stops!!!!

Better baffles or accusump are the only things that will really fix it, I drive round the problem at present but would like a cheap effective fix.

Most good speed shops should stock them. There are numerous places in Sydney.

From an independent US motorsport supplier...

The best and original coolers for motorsport, fitted as original equipment by most leading manufacturers, McLaren, Penske, Lotus etc.

Just bought one:) told me dimensions are 300 x 250 so not as huge as they look in the photos, besides a bit of extra oil never hurt anyone.

they use 3/4" banjo fittings (supplied) and the coolers are made by Serck;)

the guy told me that they are the same one Nismo use for their N1 models

Steve, Let me know how it goes, I plan on getting an oil cooler soon.

If you fit a fast acting oil pressure gauge you'll see that the RB25's suffer from oil surge just like the RB26's.

I think Sydneykid can modify the exisiting sump for extra capacity etc.

Paul, shall do, big cooler means extra oil volume too, cant hurt.

Brendan, definately will be fitting thermostat and remote filter, just need to fine some:) I am looking for a remote filter with thermostat, rather than inline sererate thermostat, but it is proving rather illusive. got quoted $20 per foot for braided 1/2" line from OG speed shop - going to have a look tomorrow.

    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
