what is the biggest difference between the gtx and the stock 1.8 besides the turbo? i know the manifold on the gtx is made to handle the turbo and so is the ecu, but is that about it? i'm asking because i have a turbo, but i blew my head gasket. i was thinking of doing the swap thing, but i was also thinking of just getting another stock gt engine or rebuilding mine and putting the turbo and the manifold off a gtx on it. i think that would save me some money and i won't have to wait for the engine, but am i thinking right or is it more to the gtx than the turbo? well if anyone can help me i would appreciate it. i have $1000 and i'm just wondering the best way to spend it.
