hi, i am new to Honda and just purchased a 93 prelude s. i imagine it has the h23a 2.2 liter engine. i bought it as a rebuild. the motor has bad rod knock (blown headgasket is the culprit). the car has 197k on it. i wanted to know how hard an h22a vtec swap is or should i just rebuild what i have. an also i have two 86 civics, both standard models, would the stock 5 speed tranny bolt up to anything i have? any help would be great and thanks alot
