My friend has a 91 civic hatch with a 1.5l. It burns a lot of oil and we are thinking about getting our hands dirty. What could we do by ourselves to give this engine some more life? I was thinking about changing out all the seals and gaskets as well as cleaning out the internals. Please give me as much info as possible. Links to DIY guides would be great as well. Hopefully we can get this thing ready for boost so any suggestions on a cheap turbo would be great. We have good mechanical skills for the average joe so shoot away with anything u got.
