Small turbos were the later models and ran a different management to the earlier big turbo models, in standard form its the quicker car around town, to convert to big turb spec you'll be looking at around 2500 to 3000
Lux models were available in big and small turbo.
Common probs! minefield could be anything m8, but fuseboxes are notoriously crap, check all the electrics. Everything isexpensive so make sure you get a good one, even stupid wee things cost a fortune
chassis number should start with WFOBXXGKAB and end in 7 digits, small turbos will have this on a plate in the passenger side of the dash, viewable throught the front screen.
Iv got a buyers guide that i made up when i bought mine and i would put it up here but iv not got a clue how to do it
Will mail it to anyone if they want it
