I am rebuilding a 83' 633 with spares from 87' 635 doner which is a runner.
I have finished the motornon the 633 with cam injectors and header. It is a solid runner with 155+- psi in all six cylinders.
Realizing the EMS on the 83 can't be chipped has any one had experience with a swap in of a 87 system on to the 83' 633 platform?
I have asked the local dealer who is working with me on the mechanical setup to investigate the opportunity.
I think I am not the first one considering a EMS swap.
Any comments?
Thanks Ian H
