Aftermarket vs OEM radiator

Hi Guys

Last week my radiator started I picked up a hairline crack on the tank of my oem radiator.

I would like to what would be best, Fix the oem one (change tank) or replace the entire radiator with an aluminium one?

Thanks

I'd go aluminium if it was me. Probably cheaper also.

New radiator would be best but be careful what you buy as there's plenty

of cheap crap that looks nice but isn't as good as an O/E rad from Toyota

Quite a lot is advertised as uprated but i very much doubt a lot of it is.

OEM, Copper core, job done, lets chat again in 15 years

Thanks Guys

Would the oem be a wise option even if I have bpu+

Yes will be fine for bpu+

Srd rad job done

I would also go OEM if not running a big single turbo, and then the STD rad will cope fine, if you go for a large alloy rad it can have the undesirable effect of over cooling the engine, especially in winter.

Thanks

Would it be beneficial if I change the plastic tank only to aluminium as the core seems perfect?

I don't think that would be cost wise, also you have no idea what the core is like inside.

One of the Australian members uses an OEM rad on a 800whp big twin setup, if an OEM rad can keep that cool down there I don't think you'll struggle over here

Genuine Toyota Rad if you can get hold of one!

Failing that both Whifbitz and SRD have there own aluminium rads which are great, And a bonus with them is they also look the part in the engine bay

OEM radiator on mine

Fluidine rad, best alloy rad for the supra but are £400 + new.

If that's two people using OEM rad, does that mean its good for 1000fwhp?

Is it recommended to upgrade the fans then if going big power?

Still using the stock viscous fan on mine

Actually Fluidyne has had alot of quality issues and isnt considered the best at all. PWR and Koyo should be the top alloy ones. I have a Fluidyne on my Supra and it was warped from new and now it's leaking at the top on one of the welding seams.

The ARC radiator was tested in the USA on Ken Henderson's Big Twin Supra. One of the Few radiators I've ever heard to have superior cooling capabilities over the stock radiator. It's what I have on my Supra as well. And while most recommend the stock clutch fan over any aftermarket setup, The SRD twin fan kit is no joke... Even running the car hard for extended periods my car never goes over set temperature parameters. The ARC/SRD setup is also extremely effective in stop and go traffic.

My OEM replacement (ordered from Toyota & fitted in Japan) is a Koyo so I would place my trust in Koyo if going alloy.

Thanks guys

I'm thinking of keeping my oem radiator (since it has a brass core) and just replacing the plastic tank with an aluminium one. To get the best of both worlds.Any thoughts?

Has anyone tried this?

If its the original rad its 20 years old, i wouldn't waste any money keeping the old core

and just buy a new one, either o/e or a known quality aluminium one

Chris Wilson use to sell an uprated stock type rad that I had on mine, very nice unit but I sadly ruined mine at RAF Marham

Next time round I went with a Koyo and thats been on the motor ever since.

You only really need an uprated / bigger core if you have a whopping great FMIC blocking it or electric fans and are using it on circuit

The Fluidyne rad on mine was poor, fitment wasn't great and coolant temps - in HK summer - got quite high. When I did the single conversion it got swapped for a Power Enterprise aluminium rad which has a double core and lowered temps significantly. IMO the PE rad was the best available for the Supra, unfortunately they are now discontinued.

just fitted a KOYO rad on mine .. VERY nice quality ! did shave a couple mm of the lower rubber bushings to get the upper mounting brackets flush. but other than that the fitment is spot on .... dont come with a filler-cap though :S

I asked MVP and Titan motorsports, both got back to me saying the same thing; Koyo

I would go OEM or a Koyo Aluminium, I put the Koyo on the car a few weeks ago; fitment and quality was excellent
