Hi Guys,

This is a C&R Radiators water to oil heat exchanger. Suitable for wet or dry sump installations but wont fit a stock car easily.

Ideally you use this with a cross flow radiator where the bottom hose is on the pasenger side of the car. Cool water from the radiator then goes through the heat exchanger to the block.

This is the second largest heat exchanger that C&R make and is the 18 plate version. For more info look here.. http://crracing.com/custom_built/external_heat.shtml

Cost me just under $600 USD. Will accept swaps for parts to suit an R34 GTR or $300 cash + delivery.

Item is located in Cairns, will freight anywhere...

It weighs about 8KG despite being aluminium, the heat exchanger core is copper.

Reason for selling:

Change of plans.... I was using some custom watercooled heads on my twin turbo VW race engine that allowed me to then use this water/air heat exchanger for oil cooling. The limited space in the car for radiators made this heat exchanger a very convenient method of oil cooling as all the radiators are used for cooling coolant only. Ive now switched back to air cooled heads, so the entire cooling system has been revised.

Its best to run the cooler on the pressure side and preferably with an in-line oil thermostat so your oil temps warm up faster and dont get overly cool on the track. I suppose you could run it on the scavenge side as well, though your oil temps where they enter the block would always be lower than your thermostat would be rated at due to plumbing length and heat radiated from the tank.

You never run a cooler on the suction side. At the most you run a strainer on the pickup or scavenge stages to protect the pump from debris in the event of a blow up.

Oil in and out fittings are a generic metric thread, I cant remember what exactly though. I had -16 fittings in it, but they are in my peterson dry sump tank now. All the sizes for dry sump systems seem to be pretty universal, the threads are the same on everything. You can buy adapter fittings at pirtek that fit with -8, -10 or -12 if you want to run smaller.

      I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp

      Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆

      A little PU bush story

      By GTSBoy · Posted

      Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
