ok it's long but you can skip to the middle if you want. here is where im at. i got my celi 1994 mabey 3 months ago. my plan was to do the 3sgte swap. only problem is, i got an st. now my new plan is to do an engine swap (practice) sell this car to get a gt-four and either rebuild the engine or take it from there. my question is, which engine should i go for. i have the 7s-fe now but i know it wont go much longer with me at wheel and 237,000 miles on it. i have been thinking and i think i dont know the diference between the 4age silver top and 4age black top, or if the 4agze(supercharged) is any different. it just came to mind, buuut you think i could turbo charge any of the engines in the future? or would goin after the gt-4 just be easier? or what goes into turbo charging your car(components to consider)?any answers to all or any of my questions would help alot. lemme know any advice as i would be doin this in ma front yard and with friends in my automotive technology(high school) class.
