Radiator re-core Problem

My radiator was recently re-corded after crashing my R33 GTS-t. I picked the radiator up today and it feels heavier. I know it was aluminium before because it wasn't painted and was really light. Now the entire radiator has been sprayed black and im thinking it’s something other then aluminium.

I have no experience with radiators and just wondered if it’s easy to tell by looking at it? I want to get more of an idea before I ask the guys who fixed it.

It cost me $340 for the re-core.

Any help would be greatly appreciated.

AFAIK every radiator recore done for less than $500 is a brass or something. If you want to pay double that you can get a Trust or Koyo race type in polished alloy.

The standard one is alloy but the replacements are better. I have a triple core in mine.

Is that a triple core copper or aluminium. hey do you know how to tell how many core your radiator is?

Copper has better heat sinking properties than aluminium so it's probably going to be a more effective radiator. But it has a fair bit of extra weight, and I imagine it's not nearly as corrosion-resistant, so I dunno.

Either way, copper is more expensive than aluminium. Whether a better option or not, you got a more expensive radiator for your money.

Triple core refers to the number of layers the radiator has. The easiest way to tell is by the thickness of the radiator. A single core is usually only no more than 10-12mm thick. U can count the number of cores by looking down the  radiator through the top

Looking through the radiator cap hole it has two holes for each fin which run from top to bottom. I guess this means double core.

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
