Ahoy Gents,

I have just swapped my early 83 944na motor for a later 87 motor.

There are slight differences to the head and i was informed the cam shaft between these two engines was also changed slightly.

My question is should i also change the ECU and MAF to as im currently still running the original 83 setup

- or - should i just run the old camtower / camshaft to avoid any sillyness as the gain in hp might be so minimal or none-existent.
