We have started setting up the GM Ecotec engines for airboats bigger than a Mini. These engines are VVT ( Variable Valve Timing ) and SIDI ( Spark Ignition Direct Injection ). They develope max torque at 2000 rpm and just sip gasoline. The 2.0L Turbo LNF developed 310 HP and the 2.4L LAF will put out about 210 HP. We have learned how to set them up to run standalone so they can be put on a boat, dune buggy, antique car, sand rail, ect. Here is a video of the 2.4L LAF on a test stand.
