i have a 1jz in my 89 supra when i put the motor in i had taken out all ac lines condensor took the compresssor off the motor lol well now i'm regreting that i did that now the problem is i cannot find the ac compressor that came with the engine i tried searching the forums and the info isn't really clear. some people said that you can use a 2jz compressor but you have to change the head with one from a 7m compressor i just wanted some verification that the heads are swapable and that the 2j compressor bolts up to a 1j block thanks guys
