what do you guys do for cooling? im thinking about goin with a PWR civic halfcore * gotta clear my turbo manifold etcc* and converting it like javier from full-races what are you guys doin to make sure the SR20 doenst overheat? thanks

Its easy: get the biggest radiator you can find. Most of the SR cars use a Koyo or larger and some form of underdriven water pump puller or electric water pump. SRX cars run big ass Fluidyne radiators like this http://buckfang.com/gallery/albums/album11/IMG_7366.jpg.
A Civic or half-anything radiator isn't going to cut it. If your stock radiator interferes with your manifold, then you need to talk to your fabricator about getting some skills.
hahah i make the manifolds. im tryin to do an equal length i can probably find another area to moutn the wastegate, i just wanted to it in the frnot, **** make a full-race style B13 manifold for personal use. and i know javier runs a PWR civic half core and sai dhe ran in AZ heat all sumemr with no radaitor fan and never overheated. btw whats the specs on teh howe radaitor u ordered if u can provide me with everyrthing i need to get from him to get a similar core fo rmy car that be great i have no prob chopping the sh*t outa my radiator support
Racing is much more intense that driving around in Arizona. Besides, we race out in the high desert where track temps are 120+.
Someone in the SE-R community is working with Howe on a drop in radiator, but the Howe guy wouldn't tell me who. I'm sure if you call or email Howe and ask to buy one they'll let you know.

since you wont have AC, you could easily change the radiator so that it mounted in front of the core support, then add some ducting to keep the air from going around the radiator. this would give you some more clearance, but might interfere with the intercooler.
that Civic radiator wont cut it.
youre also going to need an oil cooler to keep temps down. the radiator alone wont be enough.
i have an oil cooler (11.5x7.5") and the griffin radiator, and i got it to maintain a steady 195* coolant temp and 210* oil temp for an entire 20 minute session at 17-20 psi. no cool off laps. the Toyo RA-1s were overheated WAY before the car did.
It sounds like you would suggest a Fluidyne or Howe over a Koyo for SRX...is this for B-chassis, S-chassis, or both? Because at this point I am leaning toward either a Koyo for ease of installation, or domestic (V-8) Summit aluminum radiator.
i would recommend against the summit radiator. if it has the cap on the end tanks, you have to tilt the thing out from under the core support. if you dont have much room (and it sounds like you dont) it will be nearly impossible to fill the radiator. i have this problem, though it luckily has just enough clearance for me to tip it out and get the cap off.
if you get one, make sure to add the filler neck so you wont have to do this.
I installed a CSF all-aluminum radiator in my ITS NX2000 to replace the Motorsports NX2000 radiator. My temps dropped from high-180s/low-190s down to consistent mid-170s during races. For the most part it bolted right in, but I had to slightly modify the upper tab mounts to account for the thicker radiator.
A caveat, one that I understand is also an issue with Koyo radiators: the upper and lower necks are smaller than the factory radiator hoses. According to the rep at Absolute Radiator (where I got it) it's there to be able to use the same radiator on cars other than the SR20DE-powered ones. They ship you some cheesy rubber adapters that you slip over the hose fittings to make them bigger.
Well, that's plain silly; why get a bigger radiator only to have the inlet and outlets reduced? For us it was unacceptable; we cut the fittings off the radiator and welded on the correct-sized hose fittings using stock aluminum tubing and a beading tool. I don't recall the proper size but I can look it up if anyone is interested (you can also measure yours).
As noted, it works fanatistic in keeping the car cool (and the driver too, since I don't have to run with the heater on full-blast...)
Not much less than the Koyo; maybe $15-20? My purchase decision was based on availability at the time; the only physical difference seems to be that the Koyo has cast end caps, the CSF has stamped end caps. Other than the neck sizes, I'm satisfied with the quality of the CSF.

>>> saw your article in GRM, nice ride man.
Thanks much!
I just ordered a Koyo last week from Absolute Radiator. They have 1 with larger opening now. I'll let you know of it works.
right now that howe radiator sounds right to me. price wise, and i guess if drivenasa recommends it ill go for it. i have no problem cutting our my radiator support upper tie bar like drive nasa to fit the radaitor, ill just run hoodpins after, no biggy to me.

Actually, they have a new design that has the correct size necks. Edit: Oops, should have read further in the post.
The Koyo is nice, but you can get the same or better for less $ with a custom unit from Howe or elsewhere. I chose Howe because they have a great deal of flexibility in spec'ing out a custom radiator- including tabs and brackets for it to drop into stock location. And it was a good deal cheaper than the Koyo... mine is arriving today, and although I didn't have all the tabs put on for it to be stock, it was only like $250 shipped.
Definitely shop around when getting a radiator, especially for a dedicated race car since you'll have more flexibility with its size and mounting and you can usually get a domestic style for much cheaper.
btw drive nasa looks like you modified the lower portion of your radiator support is that correct ?
That is correct- Jeff cut out the top and bottom radiator supports to fig the big Fluidyne. His was the only car that survived "The Scorcher" in Las Vegas back in 2002 I think it was. (August in the desert, 2 pm race. I think the track temp was like 150 or something ridiculous... people were cooking eggs on the paddock. I know that 95 degree shaded garage felt like standing in a refridgerator.) Everyone else blew the motor on their racecar and a few on their tow vehicles heading home!

Errrr...so for my EC car, you think a custom Howe is the best bet? And I suppose I would have to send them dimensions, including mounting tab locations?
HotshtSR20 recommended against a domestic radiator if the filler cap is on the endtanks, because of issues with filling the radiator...any thoughts here? I ask because you mention a "domestic style" in your second-to-last post. Thanks.
