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.

Contact: Ian 

Ph: 0434 147 478

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.

      Red Line 75W90NS in rear diff R34 GTT

      Great to know! The guys from The Skyline Shed are going to sort it out and send what I ordered anyway. Turns out their supplier sent them the wrong stock.  But it's good to know I "can" put this in if needed

      You do not need an LSD oil in any stock (non-GTR) diff, even if it is an "LSD". This because none of the (non-GTR) LSDs are clutch/friction type LSDs. Either viscous or helical - neither of which require an LSD oil.

      Hi everyone, I bought the Redline diff oil and the seller has sent me Redline 75W90NS even though that’s not what’s pictured.  I’ve already booked a hoist to go and change my diff tomorrow but I’m not sure if the NS is ok for the rear diff in a R34 GTT I think the NS does not have any slip modifiers so would that be an issue?    thanks in advance

      Not easy to find pics from 15 years ago, but here is a partial one. Keep in mind that it curved immediately from the airbox, then kept a straight line for the MAF to read correctly, followed by a 45 degree bend straight down to the turbo. This connection was the most difficult as it had to twist as well as bend to meet the almost vertical straight section of the intake.

      Yes, well, wrt a wheel alignment, there are two types. Either: You have very little added adjustables, in which case the alignment can be done by anyone in any tyre shop or equivalent, and will only take 30 minutes, and so there is no reason to even consider leaving the car there. OR: The alignment is a major exercise because you have adjustables everywhere and so you will need to be taking it to a shop that is skilled and experienced at setting up race cars and the like, and you won't need to worry about leaving the car there.
