LS3 to FZJ80 AC conversion help (2 Viewers)

[crujones]

I recently bought an 6.2L LS3 93 FJ80. It's 95% done it runs and drives down the road great but never had the AC set up. Good news is it still has the Land Cruiser AC and the LS pump. I combed through a lot of similar build threads but haven't found really what needs to happen on the AC. Is it as easy as getting some custom Hoses made and wiring in the power? If anybody can help point me in the right direction it would be greatly appreciated. Thank you.

I’ll take some pics of what I’ve got here when I get back to the shop.

As far as I know, yes to custom hoses which any competent A/C shop should be able to fabricate. I would think you could use the wire for the original compressor and splice it into a pigtail like Santech MT0133 which should plug into the GM compressor, and add a ground to the other side of the pigtail.

It’s literally one wire. And making the hoses.

Do a search in the 80 v8 swap thread under my username. I’ve listed the part numbers and the tool (only $125-150) to make what you need. Incredibly easy.

Here is the AC stuff I used. Cut the ends off the stock lines and used the factory ends that attach to the firewall and condenser. I adapted to the condenser side close to the core support.

Buy this tool. It’s awesome.

Yes to all custom hoses.

Thanks for the input guys. I'll get to work on this soon. To add to the complication the Land Cruiser is at a buddies house in Austin while I am in Colorado. I'm headed down there in a week and a half to do 3 or 4 days of wrenching then driving it 15 hours back. It will be nice to have AC.

Make sure you have a new dryer on hand.

I would also consider this:

A/C system - how to remove the cooling unit, evaporator, expansion valve

It's summer and some of us are experiencing A/C troubles so I think it's time to do a writeup on how to remove the cooling unit, evaporator and expansion valve out of a '97 80 series. Removal of the cooling unit is very straight forward, plan on about half hour and minimal cursing :D You...

My evaporator was plugged full of muck, but cleaned up nicely. I replaced the expansion valve too.

Was just going to suggest this also. May as well while the system is open.

Thanks again guys ordering up parts now.

You can cut and weld the alloy lines like any alloy, also if you dont have a tig you can use that s*** you see on line where they are melting it onto coke can's etc . They look like filler rods but you just use a gas torch. That is what a lot of the mobile a/c trucks use as it is quick, easy and effective.
