Nah, it will run just fine. One of my friends here in town has a '90 Shadow ES that he swapped an '88 2.2L T1 engine into and it runs great on the '90 2.5 T1 electronics. The car also has an '89 CSX radiator/intercooler. The spark/fuel curves won't be optimum, but it will run fine and make good safe power. He just took it to the dyno and made 184 wheel HP and 234 wheel TQ with that setup.

 

so it will run you say, but will you run into problems like stall at stop lights or rough idles? Just looking for more feed back before I pull the motor and stick the 2.2 in the caravan.

 

No idle problems on my friends car and definately no stalling.

Since you have an '89 Caravan (SMEC) you could try to find an '88-'89 TII SMEC to run the 2.2L engine instead. You would need to wire in the charge temp sensor, and preferably add an intercooler however.

 

you refered to a charge temp sensor. I sthat the sencor right on top of the intake manifold?
