A20A3 is the 2.0L FI engine with SOHC cam for the 85 Prelude, what all is different than the 1.8L engine I have now. Mine is Dual Carb and FI might provide more HP than what I have now.

I dont have the A20A3 but want the easiest Engine Swap I can find for my car. What other Engines will swap with the least amount of problems to that car.

Any help is needed.

Also will the header work from the 2.0 on my 1.8L
