LOL you must be joking, does it even have a turbo, i cant see one?,a re you aware that diesels naturally have a lower bhp output that petrols of the same size

its a 1.8 my mothers 2008 2.0l turbo diesel Vw engine only has 110 bhp

and these 1.8's are slugs, theyre even slower than my 1.3 HCS lol

if it is standard, a air filter change wont do diddly s**t
