I'm hoping someone can help! I'm attempting to replace an SPi automatic engine/transmission with an earlier carb unit. I intend to transfer the injection and ignition gubbins from the old unit for emission purposes, but the old engine has a crank position sensor on the torque converter end, which obviously the replacement engine does not have. It does appear to have the facility for a sensor at the crank pulley, can I use this? and if so what parts do I need.
Hopefully somebody here is more conversant with the injection set up than an old traditionalist like me and can assist, many thanks in advance.

We have now completed the conversion, thanks to previous advice, and the car is running. It is still on the original automatic ecu, which I believe is causing the lazy pick up from idle.
I purchaed a Cooper SPi ecu from a well known auction site, but it has two input plugs instead of the single one on the existing ecu, and needless to say the engine does not want to play with it installed. Is there more than one type of ecu for this engine or have i been sold a pup?

Thanks for all the assistance. The car is now running much better on its new ECU. Pick up from idle is still pretty poor, if the thottle is opened too fast, ie when attempting heel & toe down changes, but I guess this is due to a problem elsewhere, which will no doubt become apparent with more investigation.
