I have the UK GTiR Rad which is probably double the thickness of the jap spec version, so if i were to get an upgrade i'd probably have to get the all aluminium thicker again core unless of course having the copper core and aluminium housing / tanks is much more efficient than the UK spec rad?

Rob: How did you get on with housing your thicker rad mate? was there much modding to be done apart from the obvious fan sizing etc?

I still have the AC installed with its associated rad so reversing the fan location would be difficult, would the slim line fan still fit in this instance?

The problem with oe rads uk or jdm is the fact the core is crimped to the end tanks, this is where they tend to leak from. Ally and copper rads are welded/braised. I still had the A/C when i got my copper rad and there was no problem with clearance for the condenser. Although ive since ditched it.

Im confident that the aluminium body and copper core version would fit with the AC rad etc but i dont know whether the all aluminium version which i think from memory is 53mm thick will fit with the AC parts still attached?

arc intercoolers are a waste of money how can u say the only time you get heatstoke is in traffic jams you go out for a hard drive then pop the bonnet up the cooler is red hot your best bet is a charge cooler ,dont waste your money

I'm hoping I have not waisted my money (again)... :doh:
I hoping the ARC will pass air better than the OE cooler which has more but thinner cores.
Aslo plan to blanket rising heat.
I have to say that on cool days round knockhill, my TMIC is not that hot.... two slow laps, followed by maybe 8 laps hard driving then a cool down. Also, the TMIC has a very short pipe run which works well when you have a small wienie (turbo) like me...:oops: ;-)

It went in fine mate, If you have a bigger turbo you will probably only be able use the passenger side fan, I think mine is over kill though.

Stick with the copper one it's a far better option.

As Rob has mentioned. It will fit but you may (will) have to ditch o/s OE fan. There is plenty of room to fit the OE n/s fan though. The rad itself is a direct fit onto the OE mounts.
The all alloy rad may be overkill though on a road going gtir.

Here's a couple of pics to give you an idea... I have no AC fitted though.

It is a road going GTiR but also will be used on the track as well. Will see how the oe uk spec rad fairs up.

I was not too impressed with the performance of the OE rad when on the track.
The temp would rise quickly and the OE rad would dump it's load into the expansion bottle then onto the ground. It's just too small when it's trying to cool a tunned engine (1bar +) and OE oil cooler.

I only used my car twice on track with OE cooling setup. It kind of coped at 0.7bar but as soon as I upped the boost to a bar it complained bitterly.
The alloy rad performes very well on track... both water and oil temps stayed down and it does not even dump any fluid into expansion bottle.
I'll be fitting maual water / oil temp gauges and will get a more acurate idea of what the temp.
You could go for an uprated rad and if it runs too cool on the road, blank some of it off.

This is true, just the AC with the all alu rad issue now.

I have had the front mounted oil cooler since day one so never actually got to the stage at where the water would be dumped into the expansion bottle although im only running standard boost etc so maybe thats the reason.

Imo the cooler the better when running it in anger on track. Thanks for the help though guys.

Im hoping to get my R on track for the first time this year, so that will be a good test for both ARC and copper rad, ive never seen very high oil temps during road use so ive not fitted an additional oil cooler yet. But like you Ant im only running standard boost (well 10.5psi). Having the condenser removed should help with air flow to the rad too.

It will indeed and comparing it to others that have you will see much lower temps.

Id recommend having the oil cooler mate as the oil temps do get very high, especially on a hot day obviously, get one with a thermostatic sandwich plate and you wont need to bother about cold winter driving with it in place.
