Talk to a Jap importer, they have heaps of second hand turbo's for around $350- $500 with bearing turbo,water cooled bearings and wastgate included..With out efi you can't run an intercooler so low-ish boost under 7 Lp with S.U or Stromburg as carby...
Could use blower off V6 Commodore or imported one off V6 U.S Ford,I have seen in Parts peddler..
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
