So this is my first update in along time.
So where to begin.
I still havn't finnished my mag center caps problems with getting the CAD program to do what I want and time to do it.
Headunit started to have issues so I replaced it with a chinese special "EONON" brand. I bought it directly from the manufactures website and it works pretty good has DVD, USB, SD card, 7inch touchscreen, Digital TV tuner, AM, FM, GPS, Bluetooth all the bells and whistles. For what I payed for it I'm pretty happy with it.
I also had some starting issues so I purchased a remanufactured genuine Nissan reduction drive starter from the States.
So the Air Con system is finally functioning as of yesterday there are a few more things that have to be addressed to get it working at its best potential.
First step was upgrading the radiator as I wasn't sure If the twin core standard Stanza one would handle the motor behind condensers especially in summer also it had started to develope leaks in the top tank so it was getting rather worn out.
The radiator I used was a ebay chinese special which so far has been really good. Its a triple core I did have to modify the lower tank and outlet. Luckly I know a guy who knows how to TIG weld ally.
Then came the task of mounting the twin condensers infront of the radiator. The condensers are from a Toyota Dyna truck. I went with these as they were the only ones I could get that would fit in the space avaliable. I went with two to increase efficiancy as they are very small. Also due to the thermo fan and brace a single one in the center wasn't an option.
Then came the task of installing the compressor. First I had to change the crank pulley to the twin groove. The bluebird I wrecked had Air Con so the pulley, bracket, and tensioner pulley all came from that. The compressor however came from a 6 cylinder L-series motor as the one from the bluebird had ceased. As the compressor was different I had to make small adaptor brackets to fit this compressor to the bracket that I as the one from the 6-cylinder didn't work with the tensioner pulley.
As you can see in the photo the reciever drier was also installed it has a trinity pressure switch one terminal will stop the compressor if the pressure gets to low (no enough gas) or to high (blockage or condensors are not cooling the gas enough). The other terminal starts the thermo fan once the pressure rises to a certain level (when the car is sitting at lights etc)
I then installed the evaporator and internal electrics. When I removed the evaporater from the vehicle out bush I also grabed the entire air box and I'm glad I did as it also had a larger and more powerful blower fan and speed resistor.
Then came getting the hoses made to suit the entire system. I had to get the fittings for the Dyna condensers custom made due to the tight space I was working with. I also had the entire system connected with flexible hoses and routed in such a way they if I need to move the condensers out of the way I can without degassing the system.
Then came the oil and gas. After a fair bit of research into retrofitting procedures I discovered most of it is opinion making what is correct and who actually know what they are on about very difficult to gauge. I say retrofit as the compressor, evaporator and TX Valve are from the R12 gas days. So I went with an Oil that supposed to safe for all seal types as well as changed any seal that I could without taking stuff apart to far. R134A was the gas of choice.
As you can see cold air
The improvements that I have to make is a small thermo fan on the first condensor triggered off the compressor to improve efficency as well as turn down the thermostate to get the air colder at the vents. Then we mite be able to fit in more gas to get it cooling even better. Being a custom system there is a bit of trial and error involved.
