a/c question.

[USMCgetsome]

I searched and noticed back in 2004 someone ramius83 and the infamous jonpowell chatted about a bracket retrofit for the rb motors. This was to use the standard a/c system and ka a/c compressor. Anyone ever do this? Better yet is anyone running an a/c system?

300Plus has his A/C working (I think). I have mine wired up and it is theoretically functional, but I need new lines and a drier. We are both running the stock RB25 compressor.

I have to figure out my overheating issues first because A/C will only magnify them.

We are working on a similar effort with retro fitting for the RB's A/C.

But will continue once our fabracator gets back from his lengthy vacation = .

keep me posted about this!

Do you guys need brackets for s13s? My compressor on my 14 fit fine? Its not hooked up or wired, but it sits there out of harms way.

I have perfect ice cold a/c that functions as it should and does not cause overheating on my RB25 S14 this'll be the 2nd summer with it. I'll try to find the thread, I posted last summer a how to guide on it. basically all u need is to have the ka lines modified to bolt up to the RB compressor. and a little wiring.

please do try to find it! (I'll search too)

AC IS FOR WEENIES!!! nah i got ac it works only when my windows are down or when i am in my house posting on nicoclub, i got a secret project i am working on that uses the ac compressor location

[Coolwhip]

its either a dry sump or a weenie enlarger pump... thats all you

[imotion s14]

Just wonder, for you fellas with AC.. hows the space for e-fans with a condenser up there?

[Darius]

Right now, I have two 10-inch Perma-cool fans on the condenser as pushers towards the radiator. However, I either do not have good enough ducting around the radiator or the fans don't blow as much as advertised. I'm guessing its a little bit of both. Either way, there's plenty of room for dual 12-inch fans mounted to the condenser. If my weather stripping job doesn't work, I'm ordering some 12-inch SPALs.

10" is not going to cut it, save yourself some time , go straight to the 12" 's

[300Plus]

Im running two 12inch permacools on the condensor, with a nismo thermostat and water wetter oh and a mishimoto radiator and in 100 degree hit with 100% humidity Ive never gone above half on the temp gauge. and I was stupid and mounted the temp sensor for the fans in the lower hose so really it could be even cooler.

I've been running A/C on my RB25 s13 for 2+ years with no major issues. I ended up using an RB26 compressor with modified KA lines that I had fabbed up at an A/C shop. My wiring guy did the wiring ages ago but from the looks of it, it's not rocket science. The system cycles off/on just like factory.

As for cooling, I have FAL 12" 210s mounted as pullers (I modded the upper and lower rad supports for more clearance) and they seem to be adequate. I also have a pignose A/C fan mounted on the front of the condenser as a pusher. (Yes, they suck MAD amps, btw) With the A/C off on a hot day, the temps stay between 80 and 85C. Mind you, this is in the jungle heat of South Florida. With the A/C on, the temps stay between 85 and 90 and if I come to a quick stop at a light after cruising for a while, they edge up to 93 or so. Yes, it's hot...but given the fact that I have a huge FMIC, condenser, thick *** Koyo rad and then the fans, it's not too bad. I'm thinking about switching to a silvia front end solely for the increased frontal area to aide with cooling or a 180sx kouki bumper with the licence plate cut out and some group N vents thrown in there too.

Yes, I'm running a bottle of water wetter, have a nismo Tstat, and have extensively bled the cooling system. Headgasket is good to go because I changed it last year and have only driven about 150 miles in the past year.

who's running an external oil cooler? Man i forever had a lil bit of heat issues with my old rb setup. nismo tstat koyo rad 2 12in pullers even with water wetter. nada. still would hit 90-99temps. hated it.

anyhow, keep that info coming about the a/c systems.

[USMCgetsome]

damn it. Where did u guys score your a/c brackets from? i got a series 2 block. I am interested in running the ka24e sohc compressor. If i understand it correctly if i leave all my s13 a/c items in i won't have to rewire much except rb engine harness and the power wire for the a/c compressor?

who's got a part number for that a/c compressor for the ka24e?

i have an external oil cooler, but no A/C. i can say for sure that the external oil cooler does a lot to keep temps down (both water and oil). my oil cooler is not even ducted and it helps a lot. before the oil cooler install, my oil temps would hit 210 and climb to 240 under hard track driving. now, the temps take a while to crawl to 210 from 180 up (when the thermo opens), and the max i've seen on the track is 230ish after 20 minutes of hard lapping. as soon as i'm on the cooldown lap the temps settle back down under 200 in no time. taking a lot of the heat away from your factory oil to water cooler helps keep the water temps down too.

for those running A/C i would really consider upgrading the fan setup. factory has a huge mechanical puller on the front (which works great if you can fit it with the oem shroud... arguably better than e-fans). in addition to that, it also has the fans mounted to the condensor. i'd be worried if i was trying to run AC with just a pair of pushers in front of the condensor. radiator will probably not see much airflow.

What about with 12" dual pullers?
