From my experience that is about as complete a bolt in as it gets. You don't need to change anything in the fuel injection. Just be sure to have the mixture setup
on a CO analyzer once you get it running. The K-jet system will compensate for the greater airflow with more fuel. You might want to use a Turbo 240 clutch to make sure the clutch will take the extra torque. If your car is an auto you might want to consider a different stall speed torque converter. This is a completely
different motor with much more high rpm power. You may have a little trouble getting it through an emissions test if you are in an area that tests.

While you have the motor out is a good time to regasket things like the oil pan, the valve cover, front seals. Replace the timing belt. Clean out the PCV breather box on the side of he motor under the intake manifold. Lot's easier to do all this with the motor out. Wish you well. Lots of work but it'll be worth it for the extra performance.
