I've got a 92' LS Integra, bout 124000 miles. Im looking into the ls/vtec crossover but im not too sure about how it works. Is it an expensive project and are the results worth the money and time invested? Also, how extensive is the work to make this change? Im wanting to boost it later on and throw a five speed in. Also, this car has not been running for a while so i was looking into a complete rebuild altogether. Appreciate the input and help.
