I recently purchased my Del Sol form my uncle and have been thoroughly pleased with the exception of one thing. POWER!!! The engine in it is a D15B7 and is way weak! I am aware that the Del Sol came with better engines and being it is a Honda, one is capable of swapping for even better types. I must admit I am fairly good at working on cars but I have very little experience with Honda. What I am leaning towards is one of the VTEC engines but I am leary of changing every single bolt. Which engine would you recommend for the greatest gain with the least amount of hassle?
