I have more 'iffys' to throw at my elders.., going engine shopping soon Options

[monkeywrench]

Ok, if my '94 celica ST is FWD Manual (does auto or manual mean anything to choosing an engine, anyway?), and I want to keep it FWD (i don't have the money or tools to convert it to RWD like i so would love to), am I limited in my options for a new engine? The 7afe in my baby is shot to hell, and I want to experiment. At first I wanted to put a 3sgte in it, but I don't know if that engine is meant for RWD cars only, or you can put it into a FWD?

Then I was thinking about finding the V6 engine out of a wrecked (not too badly) '04-'06 Camry (I forgot the engine name). I doubt I'd be able to find a 4agze, so I want something big and powerful but slightly new so i have decent fuel economy. Would most engines (besides the engines on the Sticky 'engines that WILL NOT fit into a celica') pretty much fit into the celica's engine bay (with the little adjustments of motormounts and whatnot)?

Does anyone have any ideas on what I could do? Or what cars I could inspect in my local junkyards? I know I want to stay within the Toyota family. If I got a different engine, would my celicas computer be compatible with the new one?
