3S-GE looks good and is one of the only engines i could find, seems reliable enough coming from a front end wrecked MR2 because its mid-engined. I don't know if this is against forum rules or anything but I'll link what I found: http://www.gumtree.com.au/s-ad/ipswich/engine-engine-parts-transmission/toyota-mr2-gen2-3sge-engine/1079838484 It needs an inlet manifold, do I need an engine specific one or can i just get one that fits MR2's in general? ANOTHER thing hahaha, gearboxes - what ones can I use that are compatable, what should I look out for? Sorry if this is alot of questioning but I am also doing a bit of research on it at the same time, this may just be an easier form of information. Really keen on learning how to do this properly hopefully before Christmas. :)
