A while ago I checked out the possibility of doing an Ecotec swap for a friend but it didn't pan out. It was several years back but the information that I turned up included online sources for stand alone wiring harnesses , programmed PCM's, cams and a wide variety of aftermarket high performance parts. The Ecotec design can stay together making significant horsepower. Hot Rod did a dyno test with the LSJ engine with some bolt on parts and made 372 streetable horsepower.Ecotec Bolt-Ons
What is very attractive about this engine is that its ideal for a sport compact/Fiero, its light , will probably improve handling and is capable of high end performance.
