Toyota Starlet engine. 1.3L turbo. forgot the engine code. Those little engine are pretty tough and will take upgrades pretty easily. A friend of mine boosted it all the way to 18 psi before fucking something up.
edit: Forgot to mention. He picked one up in Montreal (Quebec, Canada), complete engine with turbo, ecu and the whole shabang, for 900 bucks (CAN).
Installation of that engine is $700 labor, and a front mount intercooler setup (not required) is $600 incuding parts and labor. The engine ranges from $1000-$1600, and then you'll want a few hundred set aside for odds and ends that come up.
