8-10k if starting from scratch I think? This has EBC, PFC and "full hks exhaust mines dump pipes" already. I would be "guessing" to say that if it has dumps and an HKS exhaust it likely has fronts and cats done but fair point as that's extra cost, neither of which are that expensive. Already has ATS clutch as per the ad, Cam gears are cheap. Tune is a valid point, I'm not sure if there's a 4wd dyno here so would likely get Chris at RacePace to tune it, when I spoke to him last he said tunes for adding mods like that aren't too bad, 4hrs etc, so less than 1k. I know some local tuners but the dyno access is the issue, one of the 4wd shops might have one but they get pissy about letting people use them.
I can do all the labour required (not painting but that's mates rates).
