Okay, so ive pretty much decided that im going to put a new engine in my car this summer. it will either be one of these two: http://www.speedtechracing.com/product_page.php?id=16
or

My question is, when shopping for after market parts, i know it has to fit the engine, but what if it wont fit in the actual engine bay? Do i shop for the car body, or the engine?
