hey all i have only recently bought a turbo skyline, it has a rb25det wit forged internal, im not to sure what oil temp or pressure is normal, the oil temp usually sits at around 80-95 depending on how im driving, im goinf to be using this car for drift and just wana know what the limits should be on oil temp and is i should get an oil cooler, also another thing, it has an apexi fc and im unsure what the knock gauge means, it usualy wont go above 10, what should the knock be at? cheers

Knock should ideally be at zero...though 10 is generally fine. <20 is ok too. Knock is bad for engines and generally indicates a bad tune or overly sensitive knock sensor, and is one of the many reasons for engine rebuilds.

Not sure what PSI oil pressure should be at.

Oil temperature is important, 85-90 is ideal. If your are taking it drifting an oil cooler may be in order but you won't know till you go.

85-90 is ideal between brackets.. if ur just cruisin around doing nothing other then that... no thrashin, then ur oil coolin system sucks balls. Introducing minimal heat into the turbo will make it go to 100 real easy. while ur drifting/thrashin the car, 80-90 is ideal.. Stays relatively "cool" enough so it doesnt thin the oil out too much.

If it strays over 110 while on the track, which will happen very quickly and easily, then pull over and let the shit cool down

I had an oil cooler on my previous RX7 and while being severly cained, on a 40deg day the oil temp never rose above 85.. awesome cooling (had water spray) but on a cold day... it would struggle to get past 60deg.

Oil pressure... around 20psi @ idle is ok.. even down to around 10ish is ok.. @ around 6000rpm ud want it be @ around 60psi (from memory)

Dude, as per your other thread, what Gary (Sydneykid) said is worth knowing.

Any track work Id suggest an oil cooler - any "row" cooler is better than no cooler.

I need to get an oil temp guage so I know whats going on.

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
