You will have to be more specific with your questions regarding the years of the components you are asking about.
In either 1988 or 1989 the 1G-GZE ECU pin-outs on the Crown model changed from 24p-10-18p to 26p-16p-22p.
While its possible that all those components will 'click' together, I would be concerned that the signals generated by the non-original bits are not what the ECU is expecting and the thing will default into limp home mode.
