If you tune it properly you should get mid to high 20's mpg from a 2 1/4 lump, and if everything else is sound, a steady 75-80mph is also easily achieveable!
trust me it is definatly achievable i had no overdrive and was off the clock on a polish fresh laid motorway with no weight in my 2a and was running late for my mates wedding and made the time up sat nav said 78 when iwas crusing and i was getting 25 mpg pretty good and crusing at 50/ 55 i can get 28 but i have adjusted my jets so it runs really really sweet and fitted a big bore stainless steel exhaust and a KnN filter so it is a bit more perky or at least sounds it hahaMy s3 is my only motor, and no overdrive. Hate driving normal cars.
How on earth do you get that sort of mpg? If this is Evan nearly achievable I got some work to do.
75-80 mphreally don't know what would escape first diff, gearbox or pistons.
