good everyday car. if the plenum is square then its a 2.8. limited tuning for the 2.8 exhaust,air filter,cam etc. the more you do the higher the price and you will pay lots for bigger power gains.
if you set it up right with air filter and exhaust it can be a great drivers car as the 4wd makes the handling great in wet when the 2wd brigade are spinning away.
i have had a few and have one now(its a turbo technics car). as an all round car i prefer one to a cossie.
