What size engine can you buy for £100 ???

and where?

im just about to drop a crappy 2.0ltr black top in mine but reading that msg just stopped me in my tracks! lol

my engine has cost me around £400 so far, and still incomplete ....

its clean, has only done around 40,000 miles,

but seriously, if you know where to get decent mondy engines from for that cheap or for a few hundred, please tell me, before i make the mistake of dropping that flat lump in (which is better that the even flatter lump i have in already! lol)

thanks
