Welcome to the site mate, very much the same as above, bolt on parts is where to go maps and chips dont do anything to the money when standard as the engiine is strangled standard!
Full exhaust, k&n/mountune cias, with or without a map will see 160-175bhp
Add cams to that with a map you'll get 180-185bhp
Then you can add a cast inlet manifold, cosworth or mountune the mountune one is the best but double the price if you stay n/a, if you supercharge or turbo the cosworth one is best as you dont have to worry about the lack of pressure in the inlet
