The Brian Crower stage 2+ camshaft upgrade for the DOHC 6G72 engine is a great way to gain power, even with an N/A engine. These not only change duration, but they also increase valve lift. And, because of that, we recommend changing out your valve springs as well. Old OEM springs can wear out and lose their spring pressure over the years.
