'90-'92 CE has an early M104 or a M103 3.0L block with a M104 twin cam head. It uses CIS-E like the M103, not the HFM injection found in most M104. In short, it can be used but shouldn't be the first choice since some of the sensors are different and it uses a unique and expensive EZL ignition control module. Those differences would have to be sorted out.
