Hey all.

I've just purchased an oil cooler, and was wondering where people were plumbing them in.

My tuner had two thoughts, the first is to oil the oil just prior to it going into the turbo, the other the cool the oil post turbo before it goes back into the motor...

Just interested in what people are doing.

:confused: ....id be perhaps talking to another mechanic. Not trying to be rude, but i have never seen oil coolers plumbed up in such a way.

The best, and to the best of my knowledge the only really sensible way is to get what is called a sandwich plate. You can get them from Earls fittings or most speed shops for between $40-60. You remove your oil filter and screw the sandwich plate to the block where the oil filter goes.

You then screw the oil filter into the sandwich plate...so that the sandwich plate is sandwiched between the oil filter and the block (sandwich...get it:))

The sandwich plate has two ports, an inlet and outlet...basically you plumb these lines to/from your oil cooler...as the oil filter is on the driver side of the block, most ppl try to install the actual oil cooler on the same side to minimise the length of oil lines required.

Hope that helps:)

Cheers heaps,

Thata a much better description of option two. He's a great tuner... just a little out there with ideas from time to time :)

I guess the thoery is cooling the oil before it goes into the turbo.

No the idea is not that bad if u think about it. i ran a similar set up on my last motor and the oil temp was definately lowered. THe way i ran my set up was, from the turbo outlet i ran 1" alluminium piping thin walled in a big S shape toward the bottom oil return point, making sure that oil does not build up inside the alum tubing. after that , i bought wrap around heat sinks that you sometimes see on high pressure hydraulic line and wrap it on the piping. The theory was to cool the hot turbo oil before it got return into the sump, nothing kills oil faster than heat, But i also ran the conventional set up on the otherside of the motor.

The irony of it all was that i had a good oiling cooling set up, but there wasn't just enough of it when i need it the most, until i got a 7.5 litre capacity sump plus huge oil lines for cooler and a large oil cooler. next stop would be a dry sump and a 20litre set up in the boot i guess

    • Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?
    • Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).
    • Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
    • Perhaps the answer is... more jacks!* *proper jacks must be used.  
    • I NEVER think about using a scissor jack unless there is absolutely no other alternative. f**king things are dangerous, annoying and stupid.
