what are the main flaws with a rb20det swap?

[lucki17]

so ive got a 92 hatch and i want to put a new motor in it so i was thinking rb20, i dont really want a sr20 just because they are so overdone these days, and i want something different,i do like the sr just want something different. my question is what would be the problems in putting one in? im probably going to have pros do it if i have to be cutting shit and welding shit, but can i just get motor mounts and sqeeze it in myself? ive done a honda swap but they are like changing a tape in a vcr, not hard at all. i helped my buddy put an sr20det into his g20, is it harder then that? if this question offends you please dont even let me know just dont reply and dont read it again...
