Say you're a young hoon in a former Iron Curtain nation chock full of old Russian cars, and you want to do a low-buck engine upgrade. What to do? Well, one easy route is to start with an old rear-wheel-drive Lada and then stuff a readily-available Fiat Twin-Cam engine in it. Since the Lada is based on the Fiat 124, it's reasonably close to a bolt-in deal (though a certain amount of bash-to-fit engineering is needed, due to the whole "based on" business). This Hungarian site has the swap pretty well documented, in case you're tired of the Soviet-style power in your Lada and want to upgrade. [zsiguli.hu]
