2tz-fe Engine

[SigmaProjects]

Does anyone know about this engine. All I know is that it's a 2.4L 4cycl and there's a 2TZ-FZE supercharged version. These two engines go into a previa so at least the N/A version is pretty easy to get. What I'm curious about is if it's an aluminum or an iron block and how much larger of an engine is it? I'm planning on using this to swap out my old 22RE out of my celica, I'm not really looking for serious power ( but there is always the option for the 2TZ-FZE supercharged engine), I'm mainly looking in to it as a reliable replacement. These engines should be durable since the previas are 37XXlbs vans. Before you guys start saying "go with a 3S, 1JZs, 2JZs, 7Ms, etc.," I've checked them out and right now the 2TZ-FE is the cheapest and seems pretty close to the original setup. I thank any info in advance.
