Okay guys, decision time! I have searched with no results….

Powder Coating Vs Anodizing

1. Which is better?

2. Which last longer?

3. Which will act better as a heat “radiator”?

4. Which will be less restrictive for airflow and not clog up the fins?

Any further info would be great!

Regards,

From what i have read up so far:

Anodising is "staining" the aluminium surface at a thickness of approx 0.3 - 0.5mm therefore not affecting its thermal properties.

So looks like anodising is the way to go...

Would really appreciate you opinion guys!

As I said before, paint is an insulator, but radiator paint is designed for the job so if you must paint use that. Anodizing is no problem.

Powder coating - you may as well just go back to stock IC or blow up your engine now.

Thanks guys! I have also read that anodising can damage the IC fins due to the sulfuric acid wash.. is this true?

Would radiator paint fade/flake off the polished parts of the IC?

I have painted my intercooler black and can't see it making bugger all difference to it's efficiency if done sensibly. I masked up the rear of the cooler and the sides of the end tanks and only painted the front so it looks stealth but still allows the majority of it's surface area to be free of paint.

I bought good quality etch primer and matte black acrylic paint and laid a very light coat of each on the front of the core and end tanks. The primer was just to try and guard against stone chips etc. By masking the entire rear of the core you stop the majority of paint being passed through the core and coating the cooling fins. My cooler still works great.

Thanks for the replies... i wanted to get my FMIC black for the stealth look rather then performance or cooling gains... so far it seems that a VERY light coat of radiator paint or Anodising is the way to go...

Got any pics please krizza_ca18det?

Cheers

I would also be concerned about the durability cause a stealth black intercooler with stonechips/flaking paint will look very shit house and cheap. Would a black mesh insert over the intercooler be a better option and also guard against said stone chips?

Yeah ring around and get a few prices. You have two options in getting it anodised or that radiator paint. If anodising doesnt wreck the fins or look patchy that seems the best option as it wouldnt stone chip. Let us know what prices you come up with for both as im going to get mine done as i prefer the stealthy factory look.

Here are a couple of pics I took of my cooler this arvo. Only one small stone chip after a year of use ( but plenty of bugs! ). I don't have any pics of my mates cooler but it doesn't look too bad. I can't help you with a price either, as his uncle owns an anodising business so he got it done for free.

Sarkis have you seen the avo ones

http://www.avoturbo.com/avoshop/product_in...products_id=241

They make them in black and they use the existing intercooler lines. Easy installation. I will show you my stealthy kit next time.

anodising is so thin it is measured in microns. The longer they leave the item in, the thicker the anodising. Anodising is one of the most hard wearing and durable surface coatings you can possibly do. The intercooler would probably want 5-20 microns, BUT with some anodising on aluminium you get a very Cloudy/ Patchy finish, and can look quite bad.

If you choose to paint it, i would recommend using a thin first coat of etch primer. You can use any automotive paint/laquer on it, heat wont be a problem.....

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
