I recently bought a skyline r34 Gtt, fairly modified, I want to keep the engine in its best condition and want it to last as long as it could. Are there any specific things I should be doing? Yes I know the really basic things like changing oils every 5kms and using the good stuff, letting your car warm up before boosting. What else could I be doing ? As I am new to the automotive world I'd like to get as much tips as I could!
