RB----->A/C

[FRaCTioNaL]

Hey there. Let me introduce myself. I am new to the forums and my name is Daniel. I've been considering buying another 240 for a time now and was leaning towards an RB25 motor. However theres is one little thing I need to clear up. Can an RB swap have air conditioning?? I ask this because not one swap I have seen has it, and considering I live inPuerto Rico air conditioning is a must. Is it even remotely possible to keep the system?, cause if not I'll have to start looking at SR's.

[DuaneG]

Yes, it is possible but more difficult from what I hear.Want it done right take it to somebody who knows what they're doing. :P

[FRaCTioNaL]

Don't worry I will take it to someone who knows what they are doing. However just wanted to see if theres someone here whos actually done it so that I could maybe get some pointers.

[ISUJinX]

If youre willing to wait a few weeks... I'm taking pictures of my swap as it goes in. A/C, Power steering and all!

i had ac, it can work

custom lines is pretty much the hardest part, but i think the best way would be to make a bracket for a the ka compressor to mount on the rb.

[Darius]

haha hey Andy, I hope you know what you're getting into with the A/C. Not a plug-and-play deal.

[ISUJinX]

Oh yeah, I know. I'm pretty confident I can get it to work, even if its not right away. I'm 3/4 of the way to a mechanical and electrical engineering degree :-p. In any case, I'm doing it, it -will- work. I'm not driving a car without A/C or PS (except my track car).

[krayton]

my memory is killing me.

but i think i used the rb compressor. i only had to make one custom line to get around the turbo which cost like 30bucks.

Amen. Never have, never will.

[Darius]

here's the thread of the discussion...old, but thorough

zerothread?id=125307

[rotorimp]

Yep--It is a MUST for a daily driver here in Phoenix--I will definitely have ac. I have been looking at it and I dont think it will be anything too hard to overcome.

[FAST-DATSUN]

Power steering and a/c on 89-94 is easy...95-98 is harder but can be done...

[FRaCTioNaL]

Thanks everyone for the replies. Darius thanks for the thread, for some reason it just wouldnt appear in my searches? Isujinx I can definitely wait, I'm not swapping until after christmas so please do post your picures.

[turbo corey]

i make a bracket that will let u use the ka a/c bracket and u can use the ka a/c i make them 4 40.00 let me no

[TOPSECRT88]

The KA a/c unit was used on my RB26...just a custom bracket..

[240z4u]

I am going to get a bracket from corey, ill post on how it works out.

[Darius]

I don't understand what the difference between the RB and KA compressor is?? Why not just use the RB compressor and get a new line? Just trying to save the cost of new lines by buying a new bracket?? I'm lost here.

[turbo corey]

call me (phone removed, again.) and i do not no if it will work on a rb26 but i will find out in a week i will have my rb26 and i will see if it will work on it i will get pics give me your e mail i will get pics tommrow

[turbo corey]

i am just thring to help but my thread is locked by Kamin Moderator

dude do you seriously not see what im trying to do?

dont just post your number and try to sell things.

send me pictures of the product, and we can talk about this. till then, stop. you are a non-contributing member and half of your posts have just been trying to sell things.

till you can show me proof of your product, stop trying to sell it. NICO is not your personal advertising space. see all those banners on the right? they PAY to be there.

this is your second warning.

[turbo corey]

i e mailed you call me

[Joe]

unless you can magically transmit pictures via a telephone im not calling you.

you have been a member here for a week. whats to stop you from taking 5 or 6 member's money and disappearing? then it makes ME look bad for letting it happen. and it has happened before on NICO. you have been a member for 6 days. you need to EARN respect here.

email me pictures! no pictures! no options!

[turbo corey]

e mail you pics do i look dum y so u can make it and sell it come on if u call me then u will no this is not a good sart Kamin the Moderator do not be a mod thug

[turbo corey]

i will not sell them i will give them a way 2 sets free and u pay 4 shiping is that good 4 u now i can not rip no one off now can i give my #

HAH yea cause im really gonna waste my time making AC brackets for KA compressor's on RB's. and insulting me is the absolute worst thing to do.

p.s. i work at a performance shop for a living. it would take all of 20 minutes to make one of these brackets during my workday tomorrow. .

i will not sell them i will give them a way 2 sets free and u pay 4 shiping is that good 4 u now i can not rip no one off now can i give my #

NO

dude. your REALLY starting to bother me.

im gonna say this one last time

NICO IS NOT YOUR PERSONAL ADVERTISING SPACE. STOP TRYING TO SELL THINGS YOU FABRICATE, TO MAKE MONEY.

i laid down the rule. you email me pictures or you will not be selling these here. this is VERY fair on my part because your arent an advertiser of the board and as a general rule we delete all posts pretaining to manufacturers and shops selling things that arent paid advertisers.

FINAL WORD.

[ISUJinX]

Thanks for the thread and the replies Unfortunately most of the AC stuff was missing when I got my KA. All the interior fittings and controls are there though.

I will be posting pics and doing some sort of write up, because I like to have it documented Sounds like I just will need lines for AC. Thanks for the offer, turbo corey... but Kamin is right, you have to ern your respect here. If I need to fab a bracket, I can do it myself. And for the love of chunky peanut butter.. If you are going to try and sell things online, at LEAST have the decency to attempt to conquer the english language. My eyes were starting to bleed from your posts :-p.

Did anybody ever dig up a documented PS writeup? I found the "Bend the lines to the other side" posts, but they only mention DE lines - any chance the single cam lines will work?

Let's get back on topic here because I have a very important newb question that needs expert advice and electrical engineering prowess to answer <sarcasm>.

How exactly does the triple pressure switch work? One side is a normally closed relay that receives power from the A/C relay (low current side) then went to what was pin 15 on the KA ECU.

1) Now that the ECU is not there, can I simply ground that B/P #15 wire and achieve the same thing?

The other side of the triple pressure switch is normally open.

2) Does the switch automatically close the other side of the relay (opening the side from the A/C) and stop power from the A/C relay to the compressor? Or did the ECU from pin #9 have some control over the triple pressure switch?

What I am planning on doing, I think...is to ground #15 and simply wire everything else up as it is shown on this schematic. It's probably crappy to control the system with the triple pressure switch, but that sounds like it is the easiest way to go about it. I honestly don't care as long as it blows cold air and the compressor doesn't assplode.

See diagram for reference.

Im not too sure about the pressure switch on the compressor itself, but ive tested this the switch on the reciver dryer is a 3 position switch, 0 system pressure is open, and a system charge is closed, and a system over pressure is open again, i have tested it with a multi meter, not sure about the psi for each though but the over pressure is pretty high. I have custom la/c lines with the rb20 compressor, and get power from my a/c relay and run the power wire through the reciver dryer pressure switch as my saftey device and a aircraft grade cb/switch inside, but like everyone else its not working now, i have to replace a reciver dryer line damnit.
