motor setup ideas?????

[chd_wrly]

so i have a 04 aveo hatch. I have around $800 in it all together and finally got it runnin. It runs like a top but im unsure of the deowoo motor? Does gm make a replacement motor that gm built? Ive looked up the lsj swap and i would love too and i dont have alot of money tied up at all but not sure i want to fork the money over because i have a 18 month old and im unsure of "ALL" the parts i would need and the cost. And most likely i would have to take it to one of the preformance shops where i live and they do all the work lol. There is a shop where i live and they do hydrogen kits on cars.. It cost $1200. It will boost up my mpg, keep the motor clean internally, but ive read that its not good doesnt work and all. The guy that does it has put it on his cars a few other customers cars and one came back and said that shes gettin more mpg and all but they was busy and couldnt talk long about it. Does any one know anythin about hydrogen kits put on cars? I would love to hear feed back lol
