hi all, unfortunatly, ive had to buy a second hand engine for the car, as mine was frigged i was under the impression that mine was a twinport. however, the scrapyard said that twinport wasnt introduced until 04/05. my car is a 52plate, 03 registered astra mk4 1.6 sxi 16v. not particularly bothered like. mine has 80k on it. the one thats going to go in, has only 55k. which is a bit of a bonus. just hope its going to be okay, as its costing around the £700 altogether for fitting aswell.. cheers, andy.
