^ wut? Did he just say a basic kswap is not going to be faster than a b18c7??

There is no replacement for displacement.

OP - Cheapest option Rebuild your b18c7.

Better option (if your planning to keep the car for aeons to come)

Basic K24 swap keep the accord box on it for now, as funds free up and you find a good deal a on a rebuilt box jump on it than. (after the swap to swap the box is a clutch job basically)

Budget ~10k is what you should aim. It will be less if your putting in the hours yourself. For the initial swap. There will be some after swap costs too, depending on how far you wanna go.

Another option is ofcourse b20 vtec can be had super cheap these days.
