Yes you are 100% correct - you got me on the wind chill factor mate... it is non existent for inanimate objects :/

I'll tell you what I do know about Fahrenheit though; the temps in f are different when you look at them in the context of this discussion; 180f = 82.2c , 210f = 98.9c a difference of 16.7c (30f) which I think you'll agree is quite significant.

Those temperature calculator thingys on the internet don't work that bit out for you... lol

BTW You'll love Canada; the people are great, they love to party and of course the snow is just awesome!

There are some top snowboarding spots to check out around Fernie BC (Three Sisters) where I'm originally from.

Yeh 30 degrees Fahrenheit is about -1 degree Celsius lol (as I'm sure you know being you are from Canada). So if a thermostat opens 30f below operating temperature then that is 1c below operating temperature.

It is impossible for a standard heat exchanger (radiator) to bring water below ambient temperature. That would require a thermodynamic refrigeration cycle, eg. the vapor-compression refrigeration air-conditioner in your car. Wind chill has no affect on a radiator unless the temperature of the water is above ambient temperature. If you parked a car with a cold engine out in a freezing cold wind, the water in the radiator would not drop below ambient temperature. However if you warmed the car up first and then parked it in the same wind, it would cool down to ambient temperature quicker than if there was no wind. It would never go below ambient temperature, it's impossible.

Off topic, I've always wanted to go to Canada! Intend on doing a year-long working holiday over there at some stage; snowboarding being my main activity :D

I dont think they sell them anymore i cant find it on there site.

Sorry I hadnt replied earlier.

If you are only hitting 100 deg on the track you dont need to worry so much. An oil cooler will fix that with ease, unless you have one already.

There are also antiboil mixes you can buy that will work up to 130 degrees I believe, or a water wetter agent. I would also pose the question, is a GTR rad any thicker?

Bare in mind oil is the primary cooling system, not the coolant.

Well ive got a oil cooler here and going to install this week and well see how that goes at the next drift day but since its winter and outside temps are under 20 degrees its not a problem like this weekend hit max 90 degrees so will see how it goes with the oil cooler in a few weeks.

Fair enough, I don't understand Fahrenheit in the slightest so I'll take your word on that :P

However, it still isn't going to affect much. The thermostat may start to open then but it will only be fractionally. It wouldn't be enough to stop your engine getting up to temperature. You could have a 3 meter thick radiator (for arguments sake I'm making it ridiculous :P ) and it still wouldn't stop you getting up to temp; as long as the thermostat is in working order then the radiator plays no part until the thermostat opens.

Oil cooler is the ticket.

Please document and update the post once you have it fitted, is good info to keep record of in future.

Will do, but the results will be more use for say a day where the weather is 25 degrees plus but that will have to wait til later on in the year.

Where do they them i cant find them.

Hi mate,

The HPI Evolve Radiators are a brand new product that have just arrived - They are now listed on our website for ECR33.

Click the link below for specifications:

Good son of rajab. There's so much wrong with that it actually makes my brain hurt.

Back on topic, the Justjap cooling pro ones are OK however the bungs don't always seal perfectly (get a copper washer for the water temp sensor) and if you are still using the standard airbox (rather than a pod) the JJR ones don't allow the cool air scoop to fit properly. You can still leave the scoop sitting on top but it's not ideal. The Fenix radiators are lower on the air intake side so the factory scoop still fits. Besides that no problem at all with the JJR ones.

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
