radiator

[Shawnhalu]

Hi guys.. Do u guys change OEM radiator out to aftermarket ones?

Is it a must? if country is hot? and occasionally playing with sliding only?

what do u think abt HPI radiators?

thanks

 

[tooley]

definatly change it, thicker = better, get shot of the viscous to and go to electric fans.

TBH if you're doing any sliding, it will start to overheat soon. I can imagine that in a hot country this will be even worse.

The stock rads ok for a stock car used for normal use, but start upping the power or driving it heavy i.e on tracker or drifting and its well advised to uprate. and ditch the viscous fan at the same time as it gay.

I've just fitted a koyo rad but any thick alloy rad will do:thumbs:

 

[LuPix_S15]

Yes, yes like all the guys advise... esp for hot country and if you're drifting low speed or donuts etc (no wind cooling effect) :thumbs:


The other important mod for hot weather and drifting is oil cooler... should get this as a priority - for me it was more so than thicker rad!!

 

[Auss15]

I would seriously consider fitting an oil cooler as well if you are doing drifting

 

[Shawnhalu]

yeah thx for the recommendation i would order one soon

guys what is the difference between the 1 core & 2 core radiators? i have google it. and it came to said 2 core have greater surface contact which i dont really understand.. but what i know is they said 2 core are better than 1. the funny thing is i saw radiator price for
HPI = $400+ (2core)
Yashio = $800+ (2core)
ARC = $700+ (1 core) <-- why it cost must more expensive?

 

[JEZ 8553]

With Yashio and Arc you are also paying for the name. I doubt there will be much difference in quality so id go for the HPI as long as its an S14/S15 fitment.

 

[Shawnhalu]

i heard alot of ppls recommending koyo.. what abt koyo compare to hpi?

 

[Auss15]

Koyo are very good after market radiators with good fitment. I personally chose a Greddy/Trust because of quality(welds are excellent) and I can still retain the stock fan shroud

 

[tooley]

Koyo are good, cheaper than ARC and Yoshio but good never the less.

As far as makes go you will not go wrong with any top JDM make

ARC
Trust/Greddy
Koyo

Spoilt for choice really. ARC are by far the most expensive.

 

[Shawnhalu]

guys which koyo model r u all talking about.? i saw the koyo one selling on frsprt cheap but the frieght to my country is expensive..

i dont have so much budget. but the HPI is really tempting for me.. coz they giving offer. the diff u all said in rads is the welding or other stuff?

 

[craig8585]

They are all pretty much the same mate - as Jez said, the price difference is for the name. If it's 50mm+ and alloy, you can't really go wrong

 

[Shawnhalu]

oh thx mate!

 

[craig8585]

^^That's just my opinion of course.

Most of us in the UK with uprated rads have Apex Performance rads that cost £100 when the company do a groupbuy on them. I've not heard complaints of any problems with them at all in any respect.

 

[Shawnhalu]

Yeah great I have a look in that too.

Craig can u giv me a list of what an sr20 engine parts or overhaulling, I am kind of new to the scene.

 

[Hypnotik]

I have a Koyo Copper radiator and the stock clutch fan, my car has never been hot even after staying on the track for 10+ minutes at a time.

 

[Shawnhalu]

Great how much u got for it?

What do you mean by this? Do you mean servicing items?
