Just a Thought that crossed my mind
when i was thinking i need a light on fuel reliable car
So here the senario you have a complete s13 with no engine and gearbox
But if you were on a budget what would you do
must be N/A .....not turbo engines
1st option must be a 4 cyclinder readily available
2nd option must be 6 cylinder readily available
3rd option must be a 8 cylinder readily available
let see what you come up with
oh and it doesnt have to be nissan engines
