Im looking for a new radiator of a second hand one in good condition for my FD.
Ive been looking at Koyorad n-flo but where could get one of these.
Just wondering where you guys have bought yours from.
Also i would be looking at upgrading the fans, so any advice there?
Many thanks for the help

have a word with hayward rotary from the banner there based near the reading area i think.
going to get on the phone tommorow, hopefully it wont be to exspensive.
I got a Koyo through Clive. Cheap they arent though. It was a shade over £500 I think.
alot of people are getting the 52mm thick one off ebay for £100 and having good results with it.
i was looking at the ebay ones but just unsure about the quality of them and well when it comes to cooling your rotary theres nothing better than quality products
there are a few track cars running them if you need some results, ill have some results next month aswell as ill be fitting mine behind a 4 1/2inch thick cooler, that will test it lol
I\'m going to be changing my set up around soon and will be selling my PWR rad with twin fans and almost new hoses. Haven\'t got any dimentions to hand but could get them if your interested. Hope to be changing it over in the next week of so.
Would want £250 for the lot and its in good working order
Best picture i could find of it when i was removing my engine

Its either the 42mm of 55mm
I think im going to buy a koyo Nflow from ebay but which seller to go with, anyone bought one from the US, if so who was the seller?
Oh the boost pipe is holding nicely =)
Koyo rad = £4-500
New engine caused from overheating = £2-3k
I know what I would rather spend more on :)
Well im running a cheap one from ebay on my track FD and tucked behind my front mount it saw 86c constant on the motorway and went up to 106c after a really good thrashing on the track (last saturday so was baking)... Dont see a reason to swap it now.

Prof is running a cheap one in his FC, its started to leak more so he is going to have to change it, it seems the core and the end caps on the cheap ones are fine, it just depends on how good the welder was that put them together!

you were one of the guys i was thinking of.
Theres a car racing in the nippon challenge with one and loads of them on the road.
Unless someone could prove to me how much better a koyo was in terms of temps then i wouldnt bother
its the problems that prof has had with his that has put me off the cheap ones
Where u get yours one from Gavink?
they are all made by the same company in china so getting them from different places doesnt really make that much difference

thats the cheapest vendor at the moment but id wait a few weeks till all the companys get a big shipment in thats coming from china as you will be able to get them for under £100 again
Koyo n-flow off eBay US- £280 delivered a few months ago including customs charges. Insane to pay £400 plus from the UK.
Don\'t waste your money on new fans either, stock ones are very good.

this.
a pair of decent fans will set you back £100+, you\'ll need to make a shroud (cable tying them to the back of the rad is lazy), chop up the loom a bit and there\'ll be no benefit over the standard fans.
Just got the radiator and ive noticed there no ast nipple on it.
I know how to do a removal and lucky for me my egi will be raided for the filer cap but what are the advantages or draw backs of not having an ast.
Ive heard that you can get super heated air pockets creating problems and causing your car to over heat.
Is it wise to remove the AST?
I dont run an AST anymore and havent had any issues with overheating, i see it now as one less thing to worry about.
Ive given mine some low speed thrashing around the b roads and also flat out runs along the motorway, never had any issues there.
The biggest issue was refilling back up with water after changing the rad, its a nightmare, takes forever to burp the system, at one point i thought my waterpump at stopped working as it had that many air pockets!
cool, was a bit worried at first.
Well the job is done and ive no longer got an ast in the car but someone stole my antifreeze so filling the system will have to wait till morning.
