Radiator Options?

[Kaido_RR]

Hey,

Background Information: 350-400hp R33 GTS-T driven rarely on the street, mainly used for track work

Im currently running stock r33 gts-t radiator and radiator hoses. Im looking to upgrade, im not interested in anything china so please dont suggest it. I'm not sure what size i should go and if i go for a larger size i will have issue with head soaking.

Atm im looking at Nismo, ARC, Trust or Koyo. Nismo and ARC and both similar price and at the higher end of the scale.

Any input on size and brand would be great. Also would it be in my best interested to replace the stock clutch fan with twin thermo fans setup? And if so how do you go about removing the stock clutch fan?

Thanks Michael

Hey Michael,

I've heard good things about the EL/AU twin thermo fans. There good, flow very well, cheap and have a shroud. Only need to made minimal mods to make it fit (cut shroud and wiring). If you choose twin thermo's make sure you use a shroud to guide the air thru the thermo's.

I'll be running the twin AU falcon thermo's with a Greddy alloy 50mm radiator and a sard breather kit.

The stock clutch fan has 4 x 10mm bolts behind the vicous centre. unscrew them, take the fan and vicous out, then screw the bolts back in as it holds the water pump pulley on.

Hope that helps,

Johno

Edit, there was a company in the states who can do a 50mm Koyo rad for about $450 delivered.

Race Radiators (here in melb)

$660 inc GST replacement for the R33 GTS-t

Brilliant piece of work, ive got one in my car, and a few other guys i know are running them.

Top fabrication on them... in this instance, go the local product

Keep the clutch fan also, GTR's here in Melb dont alter the setup and make a fair whack more power than you are.

Talk to Richard at ARE, here in brisbane. Their work is top notch. They have done both our intercooler and radiator on the race car.

dont do what i did and weld tanks to a cut down mack truck radiator like i did the intercooler. the only time it gets up to temp is doing circle work at the local burnout pad, the minute it gets a wiff of air flow it cools better than my dads double door Maytag fridge/freezer. lol

ended up removing the coolant temp circut from the ecu completley as it would constantly run rich

thanks for the feedback

im not going to buy local as for the same price or $100 more i can get a j-spec one within 5days.

Also what is the go with rad cap? can i use the stock one?

[Kaido_RR]

well after looking into it looks like the trust rad for the r33 need the stock shroud to be mod. to fit
