Hi I'm thinking about garaging my 172 and keeping it as a project for track use only with the intention of putting it back on the road in the future. Is weight shedding the best place to start with this? and what can I take out to get my car as light as possible. I already have plans for coil overs, better brakes, braided brake lines, de cat pipe with exhaust system, etc etc. I have also noticed that the megane 225 is the same engine. does anybody know whether the internals of the engine are the same because the turbo off it is also an idea that I have had and what else would be needed to turbo it? I already know about manifold, would it be wise to put an intercooler on to? Any information would be much appreciated thanks.
