Rx7 kit is circa £3k landed, so expect the same, then your going to have to get some wheels to fill up the arches, £2k+, + tyres + fitting.
Prefer to go fi myself
Jeez, yeah for that price id much prefer to go fi instead! plus with that kit on youd pretty much have to have FI to pull it off, just need a spare 20 to 30 grand. Then i'd just get a GTR instead
