Hi All ,Tank size`s are different & top fixing point`s are different to so you will have to do some work ,i will get detail`s this week so if your happy to WAIT then i shall post as soon as i have info ok,cheer`s Chuckie.

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Has anyone else noticed that the S2 radiator part number in FAST has been superseded?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

"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 a there 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.

awesome tom,care to write it in engarish?

    • Thank you, 100% the intent. New coils were due and the 17" sixers look/feel loads better than the stock wheels. The aero options are so spot on.   Thanks for the warm welcome, all!
    • 98 r34 gtt Been rocking my latest setup and car running like never before. Have put a good 200 miles on it since all the latest changes and additions. everything is dialed in and have been driving it a bunch.   However, all a sudden last weekend as soon as I pushed throttle passed 4k and the engine stumbles, (slow or fast acceleration) hesitates and doesn’t go above 4100 or so, like a misfire. Everything else seems fine. I had a “good” set of coil packs that I removed from car when I first got it when I changed them over to new coils. I swapped out current ones for those, but no change. I also changed the plugs, no change. Seems to rev over 4 when out of gear with no load just fine no “misfire”, but as soon as its in gear with a load of any kind, it “misfires” as soon as rpm drop back below 4 k it runs perfectly, smooth, starts, restarts and drives fine as long as I keep it below 4 k while in gear. All readings look fine, no CEL   Any idea as to what could all a sudden cause an issue when pushing rpms passed 4 k?
    • When you say your cams are 272/262 is that 272in and 262ex?
    • We're arguing semantics. I am saying 45 accel and a 55 deccel ramp are "2 ways". Even a 45 degree ramp and an 89 degree ramp is "2 ways", because it is literally... two ways. The cusco 55/30 ramp is a 2 way. It's two ways. I get it though - in normal nomenclature a "2 way" would be 45/45 or 55/55 or 60/60 i.e the same locking in both directions. And something like 45/65 would be considered "1.5 way". I would then say if we're getting into the nitty gritty then every locking diff is a "2 way" diff and we should not speak in 1.5, or 2 ways but ramp angles instead. Which ofc if one of those ramp angles is 90deg, that side is not doing any locking. :p So Nismo don't obviously sell 3 things. The fact of the matter that they only sell two items really goes to show that there's a 2 way and a "1,5 way" which is really a 1 way. I believe the actual lockup for the 'adjustability' of the GT pro is really just setting preload for when the ramps actually start locking up. It's not changing how much 'wayness' there is. It is (somehow) horribly explained. People just buy whatever diff and go "locks up good bruh" and that's what ends up on socials forever.
