1kd was available with auto and manual.
2kd manual only. Fitted to r151f which is i junk. Ask me how i know.
They have faults. Throttle response is poor and you have to rev the tits off them to make them pull. Bellhousing is same as a KZ. I have one in stock.
You could run an auto but it would be miserable to drive. The factory suto for the 1kd was an a750f which has its own ecu as its fully electronic. Iirc the ecu has immobiliser on board so you will need keys to match .
Iirc the factory kd ratios are 3.05:1
I also have wiring diagrams. If you want my opinion on the swap yoill have to ask for it
