The Quick and Dirty Answers

Radiator: I got my OEM NX radiator from O'Reilly Auto Parts for $114.99. Two rows, full width, and it's got a cooler implement setup in the middle so you can be creative with oil, gear oil, whatever :) I've got one in my Classic, with 0.00% problems.

================================================== =====

Cams: Jim Wolf's cams are just about the best thing for a Nissan. Below are what I've picked up from SEARCHING and from personal experience.

Reference: Highport cams
Intake >>248* duration >>10.0mm lift
Exhaust >>240* duration >>9.2mm lift

JWT S3s >>260* duration >>11.3mm lift
Some people say there's little to no seat-of-the-pants change without headers, intake, and 2.25" or 2.5" exhaust, though dyno charts show otherwise. I personally think they're great for toolin' around town in, and other peoples' experiences suggest that they're not too shabby with nitrous. Top end is definitely quicker, area under torque curve is increased in top-end, and there is little to no loss of tq in the lower RPMs. No, I don't have a dyno graph, sorry. My bookmark link's broken.

JWT S4s >>266* duration >>11.8mm lift
These WILL make your car idle like a small-block chevy so if you're trying to be sneaky, these are probably not for you. There's a little loss in the bottom end torque (both measured and felt) but the top end is ridiculous. If you are boosting, or planning on turbocharging, this will probably be a good investment. If you're running these normally-aspirated, don't do so without the usual I/H/E, and I would have it dyno'd with Air-Fuel ratios to make sure it's all sane. And, no, I still don't have a dyno graph. Yay Firefox Explorer.

S5s, for turbocharged applications, have too much valve overlap, and have had problems with valvetrain reliability as of late, so I wouldn't reccomend those to someone walkin' in.. C-series cams, according to some people on the forum, could possibly net some more top-end, and higher peak HP, but my somewhat educated guess would suggest that S4s will have a wider, flatter tq curve. Reference these judgements in multiple posts... from Kojima, Miko, and others.

HOWEVER! You're talking about a GA, so, this whole post about cams means nothing, unless you swap that nasty iron-block out :)

Hope I at least helped with the radiator part. Search please!
