Help me please tryin to beef up 318

^^What KK said. Wise words.
But you're not saying where yours is deficient. There's a bewildering amount of mods you can do, that will affect your teener in different ways.
So, Are you going racing? Or do you just need a bit more Giddy-up off the line? Do you need to tow something heavy? Are you trying to keep up to somebody? Are you looking for bragging rights? How much money do you have to spend in total, cuz some/lots of mods don't end with the engine. How much of the work do you anticipate to be doing yourself, and do you have a weaterproof place to do the work? Are you thinking of buying tools? And so many other questions.....
