okay, so here's the deal. i've been leaking coolant through the head for awhile. i took the car to my mechanic, and he said i either have a blown head gasket or a cracked head. either of which i'd have to fix myself, due to having no money. he also informed me that my transmission was basically shot. he's very trustworthy, and i have no doubt that it is.
so it'd all probably cost me well over $500 just for parts. well, so i was thinkin, would it be possible to drop my 1.6 liter stock engine and throw in a 4agze? i could get a good deal on the engine/tranny combo. i mean, more than $500, but it'd be well worth it. and i could get a lot more power. if i'm going to swap the head gasket and transmission anyway, i'd just as soon swap everything and get all the benefits of a good engine.
how possible is this? will it be able to be installed without major body work? please help me out, i need my car back. also appreciated is any technical info (HP, etc.). what fuel efficiency am i shooting in the range of?
