C34 Radiator Core Thickness.

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!

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
