Aftermarket Radiator and Nismo Thermostat recommendations
Does anyone have a good recommendations for an aftermarket radiator. Like many of us here, I am in the middle of an engine rebuild and figured this is a good time to install a better capacity radiator. Also, any thoughts on the NISMO thermostat? Thanks, Ernie

I will be going with the Koyo unit and several people have installed it before and are very pleased. Adam from Z1 mentioned that the Nismo T-stat has been causing him problems with throwing CELs so i'm not sure on that.

I have the nismo thermostat and the koyo radiator. I would not recommended it. It has not thrown any CEL but the install on the radiator was not just a drop in. had to do some shaving on the core support for fittment and shaving on the electric fan a little to clear the bottom pipping on the turbo kit. Too much work. I would just go with the thermostat if I was to do it again

I have the Stillen radiator and the Nismo 154*f T stat and found that the stock system the ave traffic temps were in the 195-205 range....not good for that light to light sprint
The new set up runs at 170-175 and once in awhile I see 195 in lots of traffic. The radiator fans hardly cycle anymore.

Hey Deep I have the NISMO t-stat and no issues, and the Stock Radiator. But... now that I have the TT in, only time will tell. I was thinking of the Stillen Racing Radiator.

They claim it is plug and play... just a drop in replacement. I wonder if anyone else has purchased this unit? I would be very interested in following this issue closely because we are in the same boat here.
I was going to a Siebon TCII cf hood, painted to match REDLINE. I also like GQ_ 626's front end. Initial D - maybe with the all the ventilation exposure, a new radiator would be moo. (You know, like a cow's opinion... it's moo. ) Sorry couldn't resist.... long day at work. Or would it create too much under car lift?
Keep me in mind as you discover bits of wisdom during your project!!!

I would wait for the 350EVO Fluidyne street version radiator.

i have the stillen radiator. fits just fine with the greddy turbo piping... had to shave just a hair of plastic off the bottom of the fans to get them to slide in the brackets of the radiator... no big deal at all... no part ever fits right anyway so i say its as good as its gonna get. I recommend it well enough that I retail it... if that means anything to you.

Yeah, the Koyo is a great unit, but it does require modifications and grinding to get it to fit. Honestly, I havet seen the need to upgrade. I might try this thermostat that everyone is talking about. But even on the track...albeit it was 70 degrees outside....my temp never budged. If you track your car in hot conditions, the radiator might be more useful. If they were truley plug and play, I would likely just buy one, since I have seen them for around $400shipped..maybe less. GSC Motorsports ran a special on them a while back.

i would recommend a nismo thermostat. my car was very sensitive to the heat when tuning... and the runs at normal operating temp were always less power than the runs after letting it cool down 10 degrees.

I will be ordering that NISMO thermostat, just another one of those items to add to the GRAND TOTAL. Damn my wife's going to kill me one of these days. My defense to her, "I could have bought a viper for 82k, but nooooo. Well, think of all the money were saving with this buildup. With the difference between 82k and my roadster+project costs, we'll take a vacation. Just not now."

trust me, the t-stat is an utter waste of time and money unless you are doing lots and lots of track days
Yes the KOYO is tremendous compared to stock - its not a bad install but it is time consuming. So far, that is the only one we installed, so not sure how others fit. I would not be surprised if the Blitz and PE are the same units as Koyo, since Koyo is the largest aftermarket manufacturer of radiators in the world

let me expand my last post a bit - if you live in cold climates, its a waste IMHO unless you do frequent track days. For you SoCal guys where you never see freezing temps, its likley to work just fine without a SES light..of course it could be that freaky 04 ecu again
