Radiator upgrade

Radiator upgrade

Ok so i have always had some problems with the cooling system in my r33 GTS-T, even before i reinstalled the turbo, but now that i have it seems the the condition has become much more frequent (note i have a massive, not my choice, front mount on the car and can only assume that it must be helping the problem, when the car overheated when N/A the front mount was still installed). the latest time has got me thinking about replacing the radiator completely so the engine has more room for error, i cannot find leaks anywhere and i have seen the water boil past the cap valve so i assume this means that the system is capable of holding atleast a little pressure (i have replaced the cap incase that was the reason aswell).

So my main question is there a decent-ish aftermarket upgrade for around $300, i have seen people rave about koyos but they all seem to be out of my price range, so far i have found

http://justjap.com/cooling-pro-alloy-radiator-nissan-skyline-r33-r34-stagea-rb25-rb26.html which is around $250 shipped 

or 

http://worleyautoparts.com.au/product/alloy-radiator-for-nissan-pintara-skyline-r33-r34-auto-manual-1993-2003-atmt/ for $150

basically i would just like to know your opinions on what the problem could be and/or any preferences on the brand of radiator for relatively cheap.

 

Cheers

Do you know your water pump's condition?
Do you know your current radiator's condition?
Do you have a clutch fan and shroud / Correctly set up thermos?

the water pump seems to be fine, the water definitely circulates through the system.

the radiator has no massive dents in the fins but the coolant has become murky rather quickly after the last flush, not sure where that is coming from though.

and i currently has the stock clutch fan and shroud with what i assume is a stock thermo fan (not too sure on that it might actually be on the ac but i've never seen it kick in before it actually starts to overheat) which now that i type this seems a little strange, the a/c getting warm is the first sign in the car that it is starting to overheat which might be the thermo kicking in.... i have no idea now.

Get the Worley one if you're not making massive power. I used to track my car with that and was decent, until I starting making modest power.

Just file down the thermoswitch port down flat, they are always jagged and don't seal too well out of the 3 I've seen and installed.

Reverse flush your radiator and flush your block and heater cores.

I recently flushed the whole system and it worked fine for about 3 months. i drove 8hrs straight one day about a month after and the temps were fine but i barely made it .5hrs 3 days ago without over heating on a rainy day. Could this just be really settled gunk somewhere in the engine?

And anyone else have opinions on Worleys?

I have also found a moshimoto for ~$460 shipped http://www.prospeedracing.com.au/products/mishimoto-nissan-skyline-r33-performance-aluminum-radiator.html

Or a fenix for $360

Not saying its the solution just yet but should i just go the cheap $150 worley (the car probably makes just barely over stock power, but i have possible plans to try to hit the 300kw marks so not massively stressing the car) or should i bite the bullet and spend the 2-3x more on a decent-ish brand now?

Mishi and Fenix all china...

If you're spending over $400.. might as well go Koyo or PWR

[NickRB20]

Well there ya go. I always though mishi and koyo were on the same level.
