I plan on using the Jacobs unit on my project engine. That is after exhaust, custom head work, custom intake plenum and with an aftermarket ecu or piggyback. I think you could spend the money better elsewhere on the 3.0 but I have heard a few people who were happy with it enen in a relatively stock application.
