While rebuilding the S1 Dayz RS4, I measured the thickness of the core at 25mm. I compared it to the other RS4, the one that has the "gurgles", and was very surprised to see it was only 17mm.. Even the 25G is 25mm.

I now recall that when I was fitting the FFP I broke the top hose connection and bought a replacement radiator off the forum, never noticing the different thickness. Someone flogged me a bodgie rad. My BAD..Buyer beware. When the 25G got front shunted I used the core off the RS4 to get the rad fixed. Hence it being 25mm now. It runs cool as a cucumber.

Just maybe, the reason the 17mm Stag has the gurgles is because the rad is too thin and it boils when pushed?

Next thing is to get a Rad with a 25 plus core.

Not only an FMIC but also a tranny cooler. I had thought of putting in an oil cooler but I have a remote oil filter also and it would have been a PITA to fit. The alloy rad fixed all.

S1 is quite thin (approx 15mm, same as R33 GTST IIRC)

An aftermarket koyo rad (standard construction, plastic top and bottom tanks) is thicker at about 25mm, but has fewer flutes than the stock rad, as the flutes are wider.

No idea which would flow better, could be a close call (fewer large flutes v's more smaller flutes) but surely additional thickness will improve cooling?

Y31 Cima rad is identical in width/height as the C34/R33 rad, but is double row, so a good upgrade for cheap if you can get one!

      WA PITS: Am I screwed?

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      WA PITS: Am I screwed?

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?

      100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!

      ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
