Im looking into buying a prelude and i would like to know what engine would be the best to build up

 

Well, there are a few questions you should go over before anyone can give you a good answer.

1. What generation Prelude are you interested in?
1st, 2nd, 3rd, 4th, or 5th?

2. What are your plans/goals for this car?
Do you want to go fast:
A: in a straight line?
B: around corners?
C: both A & B?
D: none of the above

3. How deep are your pockets?
