great advice tom

fine, i'll re type to your standards

"i'm unsure that the position and diameter of the top tanks for an rb26dett motor is the same as an rb25det or 25neo as the are all different head designs and may not be compatible. generally gtr models also have different radiator supports and reinforcement bars due to having a fmic as standard. This may also change the mounting dimensions of the radiator"

i fitted my just jap "cooling pro" rad today

it came with the hole for the sensor in the bottom corner but mine had no sensor (my 32 had one and my 31 has one too)

had to go to a bolt shop and get a blanking plug, also the bolts that hold the radiator shroud on are different, not a perfect fit but its good

only think i'm experiencing is the temps going up in traffic (ecutalk display) must be insufficient airflow through the thick core or a bit of air still in the system

Interesting thanks Tom. I just fitted a Jayrad replacement today, re. the part number posted earlier in this thread. I haven't taken it for a drive yet but it too had the missing bung (@*$&^#@$) which I have for the time being plugged with an old sensor and silicone, hoping that it makes a 'good enough' seal.

Had to get the car back on the road as I've been without wheels for about a week and I have had to keep borrowing a car/getting lifts; I am still in the dark about the dimensions of the stock radiator (was thinking of photographing and documenting the old radiator before I throw it out) and would still love to be able to replace with a 40 or 50mm thick all-alloy one and not have to worry about the stupid plastic tanks splitting.

Has anyone else noticed that the S2 radiator part number in FAST has been superseded? Jayrad apparently are sole Aussie distributors for Denso, whom I am guessing may have made the originals? (although I know everything has a Calsonic sticker) so maybe the upgrade was to the thicker (25mm) core, which the Jayrad part is?

i thought mine was a 24mm core but the new rad is about 3 or 4 times thicker so mine was prob 16mm too

for the bung hole i took the whole rad into a bolt shop b4 i installed it and they had a bung shaped bolt thing with an alan key hole in the back

we thought it was 5/8 unf (imperial fine pitch) but there was a metric one that was a better fit (the guy muttered something about 16mm tapered thread) go to a specialist bolt place and ask them that the nearest metric is to the imperial 5/8
