The early phase 2 16v XSi's (until build code 07664) were fitted with 186 cc/min injectors like the ones below. They also had different ECU part numbers from later cars and I think put out 132PS rather than 135PS.
I have a reconditioned set of the later ones (200cc/min) like below and the question is whether I can fit them to an earlier build designed to take the 186cc injectors? Will the earlier ECU adjust the injector pulses to keep the correct air/fuel ratio or is it likely to over-fuel? Although both versions of the 16v XSi used the Bosch MP 5.2 ECU I presume they had slightly different maps.
Cheers
