just strip it, rear doorcards and all e/w motors etc they weigh a bit!change the suspension make the handling nice.give it a good serive aswell. no point in dropping a 16v engine unless ur using it for the topend. driving an 8v gti now and agaisnt 16v ibiza cupra sport (ABF engine) theres no difference in the performance till bout 75mph and thats a stock ibiza that weighs about 1250kilos. factory statistics say the ibiza 0-62 7.9 secs, 8v golf 0-62 10.1 secs. ran 0-62 in 9.2 secs as tis stripped,ibiza in 8.4secs, engine in better condition that the ibiza even tho both around 90k on the clock! dont waste ur 400 quid on performance when your best option is lightening the car itself! spend £300 or so on the suspension and keep a nice motor with a lower insurance group for urself!
