Great thanks for the input. So from what I have read for a 606A transplant:
1. Mating an element updated fi pump from a 603A.
2. The turbo from the 603A so that you can have a vacuum operated wastegate.
3. The 4 speed tranny that I have should work fine.
4. Engine mount arms rom my existing engine should mount up to the 606 in the same position.
5. Air cleaner and exhaust plumbing need to be sorted out.

For a 603A transplant:
1. Air cleaner and exhaust plumbing need to be sorted out.
2. ALDA wiring
3. The 4 speed tranny that I have should work fine.

Am I missing anything?
