No change from 30k to produce a 600bhp car to compete with the Top cars around, more to make it bomb proof a Skyline box is around 9k fitted im told.
Dont bother though by the time you finish the Top cars will have over 700bhp. .

ps. My Saff cost 34k to get to 200mph spec & that dont include the 3 previous conversion which were then up-graded. That Ferrari sounds cheap me thinks
